alanv / tesseract-android-tools Goto Github PK

What steps will reproduce the problem?
1. Follow Readme
2. Compile all libs with success for arm and armv7
3. run the test app

What is the expected output? What do you see instead?

There are 14 testcases,I pass for testcases 1-11 without problem, so I think my 
libs are ok, I didn´t get any UnsatisfiedLinkError.

When I execute 12º testcase testGetUTF8Text method I get an error fro Junit:

Test failed to run to completion. Reason: 'Instrumentation run failed due to 
'Process crashed.''. Check device logcat for details

I pass for test path for eng.traineddata, so I think there is a internal 
problem iwth this lib.


What version of the product are you using? On what operating system?
Tesseract 3.00
Leptonica 1.66

What steps will reproduce the problem?
1. I'am trying to run the sample tesseract-android-tools-1.00, I installed 
leptonica-1.68,tesseract-3.01 and jpeg-8c and android-ndk-r7, all these steps 
gone without problems.
2. I defind the right paths for TESSERACT_PATH, LIBJPEG_PATH, LEPTONICA_PATH in 
jni/Android.mk.
3. when I tried to build the sample tesseract-android-tools-1.00 using 
./ndk-build in ndk root I got the provided error.

What is the expected output? What do you see instead?
I run ./ndk-build in android-ndk-r7 folder but I get this result:

What version of the product are you using? On what operating system?
Ubuntu 10.4 amd64, leptonica-1.68, tesseract-3.01,android-ndk-r7

can anyone help please?

Please provide any additional information below.

What steps will reproduce the problem?
1. Follow the README file for installtion. 
2. Follow the modifications in this site: 
http://rmtheis.wordpress.com/2011/08/06/using-tesseract-tools-for-android-to-cre
ate-a-basic-ocr-app/
3. Try to run the test app

What is the expected output? What do you see instead?
Expected: the test runs are successful. 
What I see: I see all(3) tests failing and the following message :

junit.framework.AssertionFailedError: Make sure that you've copied 
eng.traineddata to /mnt/sdcard/tesseract/tessdata/eng.traineddata

What version of the product are you using? On what operating system?
Tesseract 3.00
Leptonica 1.66
Ubuntu 11.04

Please provide any additional information below.

I look up the /mnt/sdcard/ and I dont see any tesseract folder. 
I created one myself. i.e. /mnt/sdcard/tesseract/tessdata/eng.trainddata
but it still doesnt work. 

Btw, this might be important: When I mount the sdcard, I dont get any 
/mnt/sdcard filestructure. Instead I get 7.9 GB 3664-3434/Filesystem/ which I 
guess is supposed to be /mnt/sdcard. 

What the reason it is named differently? Should I rename them to mnt and sdcard?

What steps will reproduce the problem?
1. On many device simulators, the install fails due to insufficient space when 
trying to run tesseract-android-tools-test.apk from eclipse.

What is the expected output? What do you see instead?
Test apk installed on device simulator, and run from eclipse.

What version of the product are you using? On what operating system?
Latest tesseract android tools based on tesseract 3.0.1/leptonica 1.68, Device 
simulator on MacOS, running tests on eclipse.

Please provide any additional information below.
I have prepared a script based on adb which pushes correct version of 
eng.traineddata and apk files to /mnt/sdcard on which more space can be 
allocated.

Please see attached files.

What steps will reproduce the problem?
1. Windows 7: follow readme instructions to build

What is the expected output? What do you see instead?
I've followed the readme at http://code.google.com/p/tesseract-android-tools 
the best I can, and I've gotten a good start, as libjpeg is compiling. After 
that, it fails.

I get:

What version of the product are you using? On what operating system?
I'm using the latest (1.00) on Windows 7

Please provide any additional information below.
I'm not experienced with makefiles and it's been a long time since I've used 
UNIX tools, so any help is greatly appreciated.

Tesseract 3.00 and leptonic 1.66 works well, but I have a
error in compiling the libraries leptonic 1.68 and tesseract 3.01. 
how can i get the new files android.mk for compile?
please help me

What steps will reproduce the problem?
1. git clone git://android.git.kernel.org/platform/external/jpeg.git libjpeg
2. git checkout e0eadaa39b72e33f032220246c771d7302ebeaf8

What is the expected output? What do you see instead?
error: pathspec 'e0eadaa39b72e33f032220246c771d7302ebeaf8' did not match any 
file(s) known to git.

What version of the product are you using? On what operating system?
1.00 on Windows 7

git show-ref | grep e0eadaa39b72e33f032220246c771d7302ebeaf8 produces nothing 
and I know I followed the readme correctly so I'm stumped.

What steps will reproduce the problem?

1. clone the project:  git clone 
https://code.google.com/p/tesseract-android-tools/ 
2. cd tesseract-android-tools/tesseract-android-tools
3. ndk-build

What version of the product are you using? On what operating system?
I use Ubuntu 11.10 for building my windows 7 shared directory (use Ubuntuk 
Android-ndk to build tesseract on windows 7 folder)


Please provide any additional information below.

I think something wrong with the file box.cpp

Please help me out from those errors.

Any help will be appreciated. Thank you

What steps will reproduce the problem?
1. See code below 

What version of the product are you using? On what operating system?

1.00. ndk-build on debian squeeze. Eclipse helios on Windows 7, Android SDK 3.0 
API 11.


Please provide any additional information below.

Thanks for the installation instructions, everything built without any 
problems. However, when I try to read a file (I am trying ReadFile directly 
since setImage falls over at the same place) I get:

03-30 14:31:49.913: ERROR/AndroidRuntime(598): Caused by: 
java.lang.RuntimeException: Failed to read pix from file


So this is my code:

TessBaseAPI api = new TessBaseAPI();
boolean ok = api.init(dir, "eng");
String testImg = getFilesDir().toString() + "/digits.jpg";
File f = new File(testImg);
ImageView im = (ImageView) findViewById(R.id.image);
Bitmap bm = BitmapFactory.decodeFile(testImg);
im.setImageBitmap(bm);
if (f == null || !f.canRead() || f.length()<1 ) {
  Log.e("ocr", testImg+ " is not readable");
} else {
  Log.i("ocr", "Trying to read file");
  Pix px = ReadFile.readFile(f);

}       }

The jpeg file is ok, since it displays in the ImageView, and contains digits 
0-9 (attached). I have also tried using ReadFile.readBitmap, but then I get 

03-30 12:07:56.143: ERROR/Leptonica(native)(507): Bitmap format is not supported


Any help would be appreciated.

Thanks
Ian

        final Bitmap bmp = BitmapFactory.decodeResource(getResources(), R.drawable.test);
        //digits is a .jpg image I found in one of the issues here.
        ImageView img = (ImageView) findViewById(R.id.image);
        img.setImageBitmap(bmp);//I can see the ImageView. So we know that it should work if I sent it to the setImage()
        baseApi.setImage(bmp);
        Log.v("Kishore","Kishore:Working");//This statement is never reached. Futhermore, on putting some more Log.v commands in the setImage function, I found out that the native function nativeSetImagePix is never accessed. I have attached the Logcat output below to show that it is not accessed.

        String outputText = baseApi.getUTF8Text();
        Log.v("Kishore","Kishore:"+outputText);
        baseApi.end();
        bmp.recycle();
error:
could not initialize Tesseract API with language=eng!

thanks advances!!!!

What steps will reproduce the problem?
1. Follow the README
2. the "git clone git://android.git.kernel.org/platform/external/jpeg.git 
libjpeg" command fails. 
3. User can't build the tesseract.

What steps will reproduce the problem?
1. Build library successfully
2. Use TessBaseAPI in my app
3. Here is the code:

                TessBaseAPI baseApi = new TessBaseAPI();
                File file = new File(link.getText().toString());
                baseApi.init("/mnt/sdcard/", "eng"); // myDir + "/tessdata/eng.traineddata" must be present
                baseApi.setImage(file);
                String recognizedText = baseApi.getUTF8Text(); // Log or otherwise display this string...
                baseApi.end();               
                content.setText(recognizedText);

What is the expected output? What do you see instead?
The content of image file must display in the EditText view, but the app was 
force closed.
And I don't know how to find out the error.

What version of the product are you using? On what operating system?
I use eclipse Eclipse IDE for Java Developers, tesseract android tools 1.00, 
API 8 android 2.2.

Please provide any additional information below.
I don't have file buld.xml in my tesseract-android-tools-1.00,

What steps will reproduce the problem?
1. download and compile according to README
2. create project with target platform < 2.2
3. run & experience crash when loading libraries

What is the expected output? What do you see instead?
When setting the target plattform to 2.2 the app will load the tesseract libs 
and execute just fine. when deploying on pre 2.2 device app will crash. 

What version of the product are you using? On what operating system?
i am using an up-to-date version from git. I am compiling on mac os x 10.6.7.


Please provide any additional information below.
The libs compile fine and work under adroid 2.2+ as expected. when deploying on 
an pre 2.2 device the app crashes when trying to load the libs.

Hi,  can any help me out with some step by step build instructions for the Mac 
OS envrioment, or even a link to a pre compiled lib for tesseract-android-tools 
?

The initial build / set up phase is all ways the very trick, and any help would 
be great

thanks,

Latest version of Tesseract is 3.02, but the tests fail when compiling against 
this version.

I want to recognize some certificate, such as driver's license.
How do I use tesseract-andriod-tools?
Who can give me a demo?

I want to know if the Binarize.java in the tessrac-androidd-tools is working, 
and if so how to use it to binarize image befor OCR it ??
thank you

What steps will reproduce the problem?
1. capture a pic with about 16 number no characters between them.
2. image size x = 500 , y = 100
3. decoded to bitmap with options.inSampleSize = 2;

What is the expected output? What do you see instead?
I want to get the line of numbers correctly, I'm getting instead fatal signal 11

What version of the product are you using? On what operating system?
win 8 , tesseract 3.2

Please provide any additional information below.
capturing an image with line of same number of characters works without errors

What steps will reproduce the problem?
1. I put the latest eng.traineddata file in the android "asset" folder
2. This is the code for copying the traineddata file from the "asset" folder to 
the sd-card.

        File tessdata=new File(DEFAULT_DATA_PATH+"tessdata/"+DEFAULT_LANG+".traineddata");
        if(!tessdata.exists()){
            try {
                tessdata.createNewFile();
                InputStream in=packageResource.getAssets().open(DEFAULT_LANG+".traineddata");

                OutputStream out=new FileOutputStream(tessdata);
                byte[] buffer = new byte[1024];
                int read;
                while((read = in.read(buffer)) != -1){
                  out.write(buffer, 0, read);
                }

                in.close();
                in = null;
                out.flush();
                out.close();
                out = null;
            } catch (Exception e) {
                e.printStackTrace();
                Log.e("tag", e.getMessage());
            }

        }
3.

What is the expected output? What do you see instead?
   I expect to copy bytes from the eng.traineddata file using inputstream.read(byte[]) but an IOException come out from the native level.I tried to do the same thing copying bytes from the file using java.io.FileInputStream() and everything is OK.I think the error concerns with Android.

What version of the product are you using? On what operating system?
  tesseract-android-tools....1.0
  tesseract..................3.01

What steps will reproduce the problem?
1. Compile the library project
2. Copy language file eng.traineddata to expected location
3. Run the test project

What is the expected output? What do you see instead?
All unit tests should pass

What version of the product are you using? On what operating system?
Latest SVN of tesseract-android-tools with recommended library versions on 
Android 2.3.3

Please provide any additional information below.
In logact I can see the message "Could not initialize Tesseract API with 
language=eng". And the tests testInit and testGetUTF8Text fail.

Building went fine on Ubuntu 10.04 with Jenkins, then I copied the files to a 
Win 7 Machine and I run the test from here.

What steps will reproduce the problem?

Iam using Eclipse for developing android app.

while testing tesseract API I got this error: " tesseract-android-tools] Could 
not find tesseract-android-tools.apk! " what does it mean and what should i do 
please help!

below is the code Iam using and there is no error in this code :

package ocr.text.phase1;

import java.io.File;

import com.googlecode.leptonica.android.Pix;
import com.googlecode.leptonica.android.ReadFile;
import com.googlecode.tesseract.android.TessBaseAPI;

import android.app.Activity;
import android.graphics.Bitmap;
import android.graphics.BitmapFactory;
import android.os.Bundle;
import android.util.Log;
import android.widget.ImageView;

public class OcrtextActivity extends Activity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

 TessBaseAPI api = new TessBaseAPI();
        boolean ok = api.init("D:/android/workspace/tesseract-android-tools/tessdata/", "eng");
        String testImg = getFilesDir().toString() + "/javac.jpg";
        File f = new File(testImg);

        ImageView im = new ImageView(null);
        Bitmap bm = BitmapFactory.decodeFile(testImg);
        im.setImageBitmap(bm);
        if (f == null || !f.canRead() || f.length()<1 ) {
          Log.e("ocr", testImg+ " is not readable");
        } else {
          Log.i("ocr", "Trying to read file");
          Pix px = ReadFile.readFile(f);

        }
    }
    }



What version of the product are you using? On what operating system?

My Eclipse version is : Helios Service Release 2

Operating System is : Windows XP

Please Reply as soon as possible Iam waiting! thanks!

First of all, by following the instructions in README it compiled out of the 
box. Thank you very much for bringing easy way to compile tesseract on android!

Just a couple of suggestions:

1) On OSX, wget is not installed by default. curl is installed instead. So I 
suggest adding the followings to README:

...
wget http://tesseract-ocr.googlecode.com/files/tesseract-3.00.tar.gz (on OSX: 
curl -O http://tesseract-ocr.googlecode.com/files/tesseract-3.00.tar.gz)
...
...
wget http://leptonica.googlecode.com/files/leptonlib-1.66.tar.gz (on OSX: curl 
-O wget http://leptonica.googlecode.com/files/leptonlib-1.66.tar.gz)
...

2) It looks like the following three instructions from README are not actually 
needed as correct paths are already in Android.mk file:

export TESSERACT_PATH=${PWD}/tesseract-3.00
export LEPTONICA_PATH=${PWD}/leptonlib-1.66
export LIBJPEG_PATH=${PWD}/libjpeg

I didn't execute them and it compiled without problems. Perhaps you may want to 
remove them in order to avoid confusion.

Running "ant release" (as stated in README) fails:

Is that actually needed?

What steps will reproduce the problem?
1. Try to make an application that uses tesseract-android-tools as a library. 
2. In the main application, attach the code that I have written below. In the 
res/drawable-hdpi include a file that you want to test
3.

What is the expected output? What do you see instead?
I expect the letters of the image that I am trying to test. Instead I never get 
any output. I know that the nativeSetImagePix function is not called upon. 
Thats all I can understand.

However, please note that the tests for tesseract given in 
tesseract-android-tools-tests ran successfully. The problem here is sending 
Bitmaps to decode for text.

What version of the product are you using? On what operating system?
tesseract-3.00

        final Bitmap bmp = BitmapFactory.decodeResource(getResources(), R.drawable.digits);
//digits is a .jpg image I found in one of the issues here.
        ImageView img = (ImageView) findViewById(R.id.imageView1);
        img.setImageBitmap(bmp);//I can see the ImageView. So we know that it should work if I sent it to the setImage()
        baseApi.setImage(bmp);
        Log.v("Kishore","Kishore:Working");//This statement is never reached. Futhermore, on putting some more Log.v commands in the setImage function, I found out that the native function nativeSetImagePix is never accessed. I have attached the Logcat output below to show that it is not accessed.

        String outputText = baseApi.getUTF8Text();
        Log.v("Kishore","Kishore:"+outputText);
        baseApi.end();
        bmp.recycle();
    }
}

An improvement request--

Would like to have methods for returning Tesseract Region/Word bounding boxes 
added to the Android API. The following functions in Tesseract's baseapi.cpp 
would do it, I think, with a result returned as ArrayList<Rect> or Pixa:

TessBaseAPI::GetRegions
TessBaseAPI::GetWords

Having these bounding boxes available would be helpful for assessing the 
coverage and quality of the results returned from the OCR engine beyond what's 
already available using meanConfidence() and wordConfidences().

What steps will reproduce the problem?
1. Convert Bitmap in to Pix Object
2. Rotate pix with Leptonica using this function from api : 
Rotate.rotate(Pix pixs, float degrees, boolean quality)
I am calling it this way : 
Pix temp = Rotate.rotate(pix, 90f, true);


What is the expected output? What do you see instead?
I am expecting rotated Image , but just a content of the Image is rotated.The 
Image self has old Dimension (I add images, you can see it)
Do I am using wrong this function or this is api issue?
Any help is very welcome.

I am writing with same Problem here : 
http://stackoverflow.com/questions/9376490/rotate-laptonica-pix

What steps will reproduce the problem?
1. I created path for tesseract, leptonica and jpeglib library package

2. I got an error with no such file(.mk)file for jpeglib


What is the expected output? What do you see instead?
Expected output is creation of .so file so that i can run the project in 
android.But i got no .mk file in jpeglib package 


What version of the product are you using? On what operating system?

Using cygwin and windows 7
Please provide any additional information below.
Please help me how to use create .mk file for jpeglib package and how to use 
tesseract code.

Here is my code sample. If I remove the Binarize operation, it works well, 
shows a grayscale image with black text and a lighter background that looks 
sharp and in focus. b is an ARGB_8888 bitmap taken from the camera in my tests 
(with inSampleSize of 2 to fit in Memory).

Pix pix = ReadFile.readBitmap(b);
pix = Convert.convertTo8(pix);
pix = Binarize.otsuAdaptiveThreshold(pix);
Bitmap bmp = WriteFile.writeBitmap(pix);
ImageView imageView = (ImageView)findViewById(R.id.image);
imageView.setImageBitmap(bmp);

When I run it, i get an output in B&W like expected, but all the characters of 
the text that was in the photo are converted to a white blocky form with a 
black background that looks like a really badly scaled low-resolution copy of 
the image. I tried to change the parameters (Global, small tiles, big tiles, no 
fraction etc...) but no luck (gets better and worse results depending on the 
parameters, but nothing close to an acceptable result). Tried to use the 
Sauvola Method after adding it in the JNI, same result. I tried to UnsharpMask 
and NormBackground before trying the binarization, do not help that much either.

What steps will reproduce the problem?
1. Use git repository explorer in eclipse
2. clone libjpeg using git://android.git.kernel.org/platform/external/jpeg.git
3. Error message: unknown host.

What is the expected output? What do you see instead?


What version of the product are you using? On what operating system?
latest, I am using windows xp.

Please provide any additional information below.
android 2.2 sdk version, and latest android ndk

I am using tesseract 3.00  .I was able to use it correctly with english 
langauge traindata but not with any indian local langauges such as hindi and 
tamil etc. 
I was getting the error at

actual_tessdata_num_entries_ <= TESSDATA_NUM_ENTRIES:Error:Assert failed in 
file tessdatamanager.cpp line 55  (Segmentation Fault).

This error generally happens when the traindata is of different version that 
tessearct but i am using same version 3.00 hindi traindata with tesseract 3.00 
and still getting this error.


Exact problem  shwon in my logcat is

Please, see the JUnit test case attached

PSM constants as defined in the ccstruct/publictypes.h are as below:

enum PageSegMode {
  PSM_OSD_ONLY,       ///< Orientation and script detection only.
  PSM_AUTO_OSD,       ///< Automatic page segmentation with orientation and
                      ///< script detection. (OSD)
  PSM_AUTO_ONLY,      ///< Automatic page segmentation, but no OSD, or OCR.
  PSM_AUTO,           ///< Fully automatic page segmentation, but no OSD.
  PSM_SINGLE_COLUMN,  ///< Assume a single column of text of variable sizes.
  PSM_SINGLE_BLOCK_VERT_TEXT,  ///< Assume a single uniform block of vertically
                               ///< aligned text.

  PSM_SINGLE_WORD,    ///< Treat the image as a single word.
  PSM_CIRCLE_WORD,    ///< Treat the image as a single word in a circle.
  PSM_SINGLE_CHAR,    ///< Treat the image as a single character.

  PSM_COUNT           ///< Number of enum entries.
};

The ones in the TessBaseAPI.java are as below:

    /** Fully automatic page segmentation. */
    public static final int PSM_AUTO = 0;

    /** Assume a single column of text of variable sizes. */
    public static final int PSM_SINGLE_COLUMN = 1;

    /** Assume a single uniform block of text. (Default) */
    public static final int PSM_SINGLE_BLOCK = 2;

    /** Treat the image as a single text line. */
    public static final int PSM_SINGLE_LINE = 3;

    /** Treat the image as a single word. */
    public static final int PSM_SINGLE_WORD = 4;

    /** Treat the image as a single character. */
    public static final int PSM_SINGLE_CHAR = 5;

Thus, the constant PSM_AUTO in java corresponds to PSM_OSD_ONLY in tesseract 
C++ API, and to get the effect of AUTO, you either need to use 
PSM_SINGLE_COLUMN or PSM_SINGLE_LINE from java code. This needs to be fixed.

What steps will reproduce the problem?
1. Build tesseract-android-tools
2. Bitmap is located under location specified in "_path" (.JPG file)
3. Code:
// prepare bitmap
BitmapFactory.Options options = new BitmapFactory.Options();
options.inSampleSize = 4;
Bitmap bitmap = BitmapFactory.decodeFile(_path, options);

// Convert to ARGB_8888, required by tess
bitmap = bitmap.copy(Bitmap.Config.ARGB_8888, true);

// do OCR
TessBaseAPI baseApi = new TessBaseAPI();
baseApi.setDebug(true);
baseApi.init(DATA_PATH, lang);
baseApi.setVariable(TessBaseAPI.VAR_CHAR_WHITELIST, "0123456789:");
baseApi.setPageSegMode(TessBaseAPI.PageSegMode.PSM_OSD_ONLY);
baseApi.setImage(bitmap);

// show recognized numbers
String recognizedText = baseApi.getUTF8Text();
baseApi.end();

4. run code on device

What is the expected output? What do you see instead?
expected output:
>> correctly recognized numbers with autorotation

What version of the product are you using? On what operating system?
latest tesseract-android-tools
tesseract-ocr-3.02
tesseract-ocr-3.02.eng.tar.gz
leptonica-1.69.tar.gz

What steps will reproduce the problem?
1. run "ndk-build" in the main project directory after checking out the project 

What is the expected output? What do you see instead?
Expected successful ndk built, instead - missing files and references are 
returned. Example:

What version of the product are you using? On what operating system?
ndk r8d, tesseract 3.02.02, Windows 7

Please provide any additional information below.
It seems there are missing source files. Some of these are included in other 
releases under the jni/com_googlecode_leptonica_android/src 

What steps will reproduce the problem?
1. String recognizedText = baseApi.getUTF8Text();
   int[] wordConfidences = baseApi.wordConfidences();
   List<Rect> rect_lines = baseApi.getTextlines().getBoxRects();
2.
3.

What is the expected output? What do you see instead?

The number counted from recognizedText should be the same as the number in 
wordConfidences.
But they are different.
So I do not know how to match each word with each confidence.

What version of the product are you using? On what operating system?
tessearct-android-tools (Its document says it is built on tesseract 3.02)
Ubuntu

Please provide any additional information below.
First, great thanks for this useful tool.
I want to examine in the recognized text, each line, each word and its 
confidence value.

For example, I am trying to recognize digits with the special font.
The recognized text is:
///////////////////////////////
\n 0 0 - - -\n
\n
 -0630000470 898005714972- -\n
\n
    - -    -       - - 5 -
/////////////////////////
And BTW, why are there "-" outputs? I only train 0123456789, the ten digits.

I suppose the space separate words. However, in this way, the count is 
different from baseApi.wordConfidences().

I have a look at hOCR.html, which has a clear vision of each line, each word in 
each line and its confidence value, boxing borders.

Is it possible to output a similar format, for example, in array, or ArrayList?

Thanks a lot.
Best

GetUTF8Text() return a String.
wordConfidences() return a int[].

In order to make sense of the wordConfidences() function, one has to parse the 
text returned by the GetUTF8Text() function into words.

However, I could not get the parsing done correctly. When I try to separate 
words based on spaces or '\n' I get an inconsistent number of words from the 2 
functions.

Help ~~~~~ 0_0

hello,

i i have task to capture test from image so that i decide  to  use tesseract 
lib,

i have successfully build the library project. and create on another android 
project name demoOcr in that i add library project as 
tesseract-android-tools-1.00.

following is my activity class.

<code>
public class OcrDemoActivity extends Activity {

    private TextView txtData = null;

    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        txtData = (TextView)findViewById(R.id.txtdata);

        File sdcard = Environment.getExternalStorageDirectory();
        File from = new File(sdcard, "Pic.jpg");
        TessBaseAPI api = new TessBaseAPI();
        api.init("/mnt/sdcard/tessdata/", "eng");
        api.setImage(from);
        txtData.setText(api.getUTF8Text());

    }

</code>

i have add tessdata in my sdcard as well as Pic.jpg

but the now probleme is when i run this project in my samsung galaxy tab hust 
activity load and finish automatically.


i have seen that on logcat that given error that request time failed: 
Java.Net.socketExcepton : Address family not suport by Protocol.

Please Help me out.

What is missing?

Regards.
Milind Kanani

What steps will reproduce the problem?
1. Follow the steps exactly as mentioned in the readme of 
tesseract-android-tools
2. Call baseAPI.init() with the correct datapath, language
3. Call baseAPI.setImage(bitmap)
4. Call baseAPI.getUTF8Text()

What is the expected output? What do you see instead?
Expected to see no error
Instead see the error: "Bitmap functions not available; library must be 
compiled under android-8 NDK" on step 3 and a NPE on step 4 (which is due to 
the error on step 3)

What version of the product are you using? On what operating system?
tesseract-android-tools-1.00
tesseract 3.00
Compiled on Mac OS X for Android 2.2

Please provide any additional information below.
Looks like ndk-build doesn't compile the jni source against the libjnigraphics. 
Hence, libtess doesn't seem to have native bitmap support. I'd very much like 
to know the right steps to build the libs so that this issue can be mitigated.

What steps will reproduce the problem?
1. I dont know how to build the three libraries t this project 
2.
3.

What steps will reproduce the problem?
1.I compiled tesseract-3.01
2.I compiled leptonica-1.68 and libjpeg
3.Add the right 3 paths in Android.mk of the sample 
tesseract-android-tools-1.00.

What is the expected output? What do you see instead?
I run ./ndk-build in android-ndk-r7 folder but I get this result:

What version of the product are you using? On what operating system? Ubuntu 
10.4 64 bit, leptonica-1.68, tesseract-3.01,android-ndk-r7

can someone help me please to found out the reason of these errors?

What steps will reproduce the problem?

I have compiled libtess liblept and libjpeg exactly as said in the README file.

I have compiled the java file in the src directory and created a jar.

My libs directory is as follow:
libs/tesseract-lib.jar
libs/armeabi:
libjpeg.so  liblept.so  libtess.so
libs/armeabi-v7a:
libjpeg.so  liblept.so  libtess.so

I created a small application just like 
tesseract-android-tools-test/src/com/googlecode/tesseract/android/test/TessBaseA
PITest.java It creates a bitmap with a text and it pass it through to 
TessBaseAPI object.

What is the expected output? What do you see instead?

I was expecting to see hello. Instead I get a sigsev

What version of the product are you using? On what operating system?

I am using the last svn version of the project.

My phone is a Nexus one.

I am using android version 2.3.2 from cyanogenmod.

Please provide any additional information below.

How can I investigate more the problem? There is no debug information...

Thanks

It looks like conversion from Pic to Bitmap (or vice versa) is not working 
correctly. This should be tested in ReadFileTest or WriteFileTest with a Bitmap 
=> Pic => Bitmap conversion.

Tesseract OCR is now at 3.01.  This tool still only supports 3.00.

The attached patch allows building with Tesseracr OCR 3.01 stable.

What steps will reproduce the problem?
1.I complie in cygwin tess-two from https://github.com/rmtheis/tess-two
2. and import in my project as library project.
3. now when i try to run the program my application myocr.apk goes in android 
emulator and install but when the tes-two project library tess-two turns come 
it display the error
Could not find tess-two.apk!

:(Please Help 

What steps will reproduce the problem?
1. Using android-ndk-r9 and the tesseract source code v3.02
2. ndk-build.cmd -j8
3.

What is the expected output? What do you see instead?

Expected successful build.  Build fails, error:

format not a string literal and no format arguments [-Werror=format-security]
cc1plus.exe: some warnings being treated as errors

Please provide any additional information below.

I fixed this by changing the line mentioned above:

jni/com_googlecode_tesseract_android/src/dict/permdawg.cpp:208:62

from:

    fprintf(output_ambig_words_file_, word_str.string());

to:

    fprintf(output_ambig_words_file_, "%s", word_str.string());

Simple enough.
