hello,

I'm new to ANDAR and I am facing some error to configure andar in Eclipse 
enviroment. Although this question has been asked earlier in this forum but 
still I couldn't find any answer for it. So please help me.

I followed all the step mentioned but when I import the andar project in 
Eclipse its showing 2 error:
1.The project was not built since its build path is incomplete. Cannot 
find the class file for java.lang.Object. Fix the build path then try 
building this project
2.The type java.lang.Object cannot be resolved. It is indirectly 
referenced from required .class files

please help me...

Thank you
Andy

hi,

andar runs slower on my new galaxy then on my old G1, why is that shouldn't it 
be way faster, because of faster processor etc.
What is the USE_ONE_SHOT_PREVIEW constant for, should it be false or true, what 
does it do ?

hi

I am a Korean student.So I am not so good at English. So please be good to 
understand my awkward English.

The first to tell you I using the phone is MOTOROLA-XT720, ndk version is 
r3

I finished all step this work :

1. Install the android NDK
2. Make a symlink from your eclipse project folder (should be called 
AndOpenGLCam) to
the ndk apps folder 
4. change line 2 of Application.mk to APP_PROJECT_PATH := $(call my-dir)
3. in the root of the NDK folder run make APP=AndOpenGLCam
4. refesh your project in eclipse
5. If everything went smoothly your libs folder will have the .so files 
that jni needs


also put camera_para.dat and patt.hero files on my sd card.

But on my device is displayed white screen.

How to solve this problem?

please help me

thank you

1. Application is run

Blank screen followed by a force close

Hi!
Great project!
I have to create an app for android mobile devices, that recognizes different 
(trained) markers and display a textbox over the marker on the screen (in the 
end, device would connect to a server, collect some data and display that data 
in text box...for each marker different data would be collected from the 
server). It is a project for my faculty...
As I am a newbie in a world of Android app programing and have little 
experience in java also (I know how to create simple apps, not much more...YET! 
:) ), I wold apriciate some suggestions, where to start to stear me in the 
right direction. Would it be possible to take source code from model viewer and 
modify it, so instead of model it would show a textbox? Or should I create new 
app from scratch using AndAR library?
Any help and info is highly appriciated. Thanks in advance!

Have a nice day!

I'm integrating min3d with AndAR for loading models (OBJ, 3DS...). In order
to do it I've had to extend AndARRenderer and instantiating my own
renderer. There're two changes needed at the code:

1.- AndARRenderer.onDrawFrame shouldn't be final.
2.- AndARActivity (which I also extend) shouldn't override its renderer
attribute (which should have accessors) if it's not null.

Do you think it might be interesting? I'm able to load OBJs and 3DSs now,
which is quite c00l :)

What steps will reproduce the problem?
1. Turn phone vertical (upright) when selecting.
2.
3.

What is the expected output? What do you see instead?
Model / Nothing

What version of the product are you using? On what operating system?
Current (downloaded minutes ago) / Froyo, whatever, should be most current

Please provide any additional information below.

Dear Everybody,

I am trying to play a sound file in AndAR program. but it looks some conflict.I 
am trying to follwoing two way to solve conflict.

option :1 

package edu.dhbw.andar.sample;
public class CustomObject extends ARObject {
private Context context;
    @Override
    public final void draw(GL10 gl) {
        super.draw(gl);

       MediaPlayer mp = MediaPlayer.create (this,context.raw.coconut);
    mp.start();
    ......................
    ........................    
        //draw the box
        box.draw(gl);
    }

here the problem is, when marker detct the program is auto exit. I think the 
problem is context.

option 2: 

package edu.dhbw.andar.pub;
public class CustomActivity extends AndARActivity {
    @Override
    public void onCreate(Bundle savedInstanceState) {

    super.onCreate(savedInstanceState);
    CustomRenderer renderer = new CustomRenderer        super.setNonARRenderer(renderer);
        try {
....................................
MediaPlayer mp = MediaPlayer.create(this,R.raw.coconut);
....}

here I used parameter "this" instead of "context" in create function. now 
program not crash/auto exit. But in draw function, how i can execute folowing 
line to play sound?

    public final void draw(GL10 gl) {
        super.draw(gl);
                box.draw(gl);
                mp.start(); 

because in draw function, mp is unresloved as the declaration problem.

So plese help me to solve this conflict/declaration problem to play sound..

Hi,

The applications AndAR and AndAR model viewer are not visible on the market. 

After reading a little on the android documentation I read the market filters 
for QVGA devices all  
applications that explicitely do not declare that are compatible with small and 
low resolutions.

They say that should be necesray to modify the AndroidManifest.xml to declare 
explicitely the 
compatibility with QVGA devices:

<supports-screens android:smallScreens=["true" | "false"] 
                  android:normalScreens=["true" | "false"] 
                  android:largeScreens=["true" | "false"] 
                  android:anyDensity=["true" | "false"] />

I cannot test it on my eclipse because I have problems to mount  the project, 
to make work the 
source code 

Dear All,

I am trying to compile the AndARPong project

created which is only 120KB(but in trunk AndARPong apk size is 225KB).I already 
tried to install my apk(120kb) in my Desire phone.it can install but program 
not open.

I don't understand what is the problem here. I download the whole project from 
trunk.

So please help me here to sort out this problem.

menas if i switch cube menu it will be drawn cube and if i change menu to 
triangle it will be drawn triangle but in same marker. But I don't understand 
how i can do this. Basically I tried following way to implement menuitem in 
customobject class:

package edu.dhbw.andar.pub;

public class CustomObject extends ARObject {

    public CustomObject(String name, String patternName,
            double markerWidth, double[] markerCenter) {
..............
..............}

    public final void draw(GL10 gl) {
        super.draw(gl);
}
    @Override
    public boolean onCreateOptionsMenu(Menu menu) {     
        menu.add(0, MENU_SCREENSHOT, 0, getResources().getText(R.string.takescreenshot))
        .setIcon(R.drawable.screenshoticon);
        menu.add(0, MENU_SCREENSHOT1, 0, getResources().getText(R.string.takescreenshot1))
        .setIcon(R.drawable.screenshoticon);
        return true;
    }

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {

...........
........

        switch(item.getItemId()) {
        case MENU_SCREENSHOT:
            new TakeAsyncScreenshot().execute();
            break;

        }
        switch(item.getItemId()) {
        case MENU_SCREENSHOT1:
            new TakeAsyncScreenshot().execute();
            break;

        }

class TakeAsyncScreenshot extends AsyncTask<Void, Void, Void> {

{
 box.draw(gl);///should be call box function
}



but its seems no effect when press menu item after program open.

Anybody can help me that how i can implement differet menu item for drawing 
different object in same marker.

Hey!

OpenGLCamActivity crashes. I tracked down the Exception to this line in
MarkerInfo.java:

System.loadLibrary( "ar" );


I guess this is where jni comes in handy. Could you provide some
instructions how to use the generated header files?


Thanks in advance,
Daniel

What steps will reproduce the problem?
1. Run the application as usual
2. Press home button
3. Rerun application

What is the expected output? What do you see instead?
Application crashes usually when it is reopened. Sometimes it just gives a
white screen

What version of the product are you using? On what operating system?
I am using it with HTC Legend (Android 2.1)

Please provide any additional information below.
When you get out of application (ex by pressing home button), onPause and
onStop functions of the activity are called as normal and camera seems to
be released as it should be. However, when I try to run Camera application
it does not work in that stage (goes back to home) Then if I try to rerun
AndOpenglCam, it crashes immediately.

Dear all,

I have downloaded the source file as .java(txt) for AndAR project from 
following site:

http://andar.googlecode.com/svn/trunk/AndAR/src/edu/dhbw/andar/

Now how i can attach this source file (.java) to existing AndARSample 
project.when i tried to open any classes/function it shows "source not found" 

I already tried to attach source(what i have downloaded).Suppose for 
simplebox() I have attached SimpleBox.java but it shoes the sourc attachment 
does not contain source of the simplebox classes..

So how I can add/attach source file to exitsting andAR.jar file?

Thanks
Jubair

I want to display the number of Frames drawn per min, while AndARSample program 
works on real device. Any one have an idea?

Hey folks,

I am creating an Augmented Reality game on the HTC Desire for my university 
honours project, and I am seriously considering using AndAR.

However when trying to get the AndARPong working as part of my research, I have 
failed!

The first error I came across was that I had to include lib/AndAR.jar
So I simply copied the file from another project, 
Is this correct? 

Because I then get an error saying that 
The method arUtilMatInv(double[], double[]) is undefined for the type ARToolkit 

Could someone please reply to this and help me out?

Thanks Euan Hislop

Dear all,

Last copule of days, I am trying to load a texture image(.bmp) inside andar 
sample project(downlod from trunk) application's coding.but every time white 
texture come to screen on marker.here is my coding for texture:

package edu.dhbw.andar.pub;
public class CustomObject extends ARObject {


    public CustomObject(String name, String patternName,
            double markerWidth, double[] markerCenter) {
        super(name, patternName, markerWidth, markerCenter);

    }

......
.....

    int[]  textureIDs = new int[5];
    private Resources res;

public final void draw(GL10 gl) {
        super.draw(gl);
.....
.....
       gl.glEnable(GL10.GL_TEXTURE_2D); 

        //Enable vertex buffer
        gl.glEnableClientState(GL10.GL_VERTEX_ARRAY);

        gl.glVertexPointer(3, GL10.GL_FLOAT, 0, vertexBuffer);


        //Bind our only previously generated texture in this case
        gl.glBindTexture(GL10.GL_TEXTURE_2D, textureIDs[0]);


        gl.glDrawArrays(GL10.GL_TRIANGLE_STRIP, 0, vertices1.length / 3);
}

        @Override
        public void init(GL10 gl) {



            gl.glEnable(GL10.GL_TEXTURE_2D);

            gl.glGenTextures(1, textureIDs, 0);
            //load the textures into the graphics memory


    Bitmap bm = BitmapFactory.decodeResource(res, R.drawable.image);
    gl.glBindTexture(GL10.GL_TEXTURE_2D, textureIDs[0]);
            GLUtils.texImage2D(GL10.GL_TEXTURE_2D, 0, bm,0);
    gl.glTexParameterx(GL10.GL_TEXTURE_2D, GL10.GL_TEXTURE_MIN_FILTER, GL10.GL_LINEAR);
    gl.glTexParameterx(GL10.GL_TEXTURE_2D, GL10.GL_TEXTURE_MAG_FILTER, GL10.GL_LINEAR);

            bm.recycle();


        }
}

here the object is four square and image will be bind in the four sqaure 
object. the coding can compile and install in phone. the four square draw but 
with white texture.I also add image.bmp in drawble folder. but still same 
result.

1. Is AndAR  open source project? Because I did not find any source code for 
modyfy the library.suppose I want to modify class,add functions,change 
parameter.so how i can do that?.Other open source project like 
artoolkit/artoolkitplus can modfy the library because .src,.h is avalaible.if 
AndAR.jar is the library for AndAR, so how we can recompile/modify this 
library? or it is not open source project?

2. What is the function of .so file under libs folder?

Anyone could help me to use a fixed image instead a camera?

If we made this reprogramming it could be easier when we're using an emulator.

Hi Tobias, 

Thanks for porting this code over. 

I'm testing AndOpenGLCam on my new Nexus One. 

It looks like the code is hardcoded to 240x160 in several places. Is this
because of performance? Or just how the original codebase was coded? I
tried to change it to use a much larger preview size, because Nexus One can
do 800x480. 

Also, is it supposed to use the autofocus in the camera? It does not seem to. 

Lastly, I did a test where I counted the number of frames where a marker is
detected vs. number of frames where it is not (by checking cur_marker_id in
the draw() routine).  It seems to detect a marker approximately every 10-20
frames. So I occasionally see the grey box show up for a few frames, but
most of the time I don't see it. 

I test by opening the PDF file on my computer screen, and fill the frame of
the camera with it. 

Should I be getting better results? 

What steps will reproduce the problem?
1. i'm try to integrate with min3D open source.
2. i  made a CustomObject4 that impelments ARObject 
3. the CustomObject4 impements Min3d RederActivity Code.

What is the expected output? What do you see instead?
i expected that Min3d Object augmented very well . 
 Min3d Object augemnted. but background is red..  

What version of the product are you using? On what operating system?
android2.0 Gallsy S

Please provide any additional information below.

 i attach Source File and result screen image.

 please.. help me

Dear All,

I want to know one information about AR in Android. Untill now there is not any 
Android phone released which has 3D hardware/dedicated graphics hardware.As far 
we know Dedicated hardware is very useful & important for rendering object in 
AR specially 3D object.Some Nokia/Iphone/Samsung/SE phone based on 
Symbian/Iphone OS already have dedicated graphics hardware.In these phone AR 
rendering performence is excellence.

So my questions is that how much the good performence(specially rendering 3D 
object) will be AR in Android without dedicated graphics Hardware in phone.I 
want to start AR in HTC Desire(Android).Is HTC desire the right choice for 
AndAR and rendering 3D object smoothlly?

Plz Suggest...

Thanks
Rassall

Hello,

How i can use same source code for 2 application. That menas we install 
AndARSample in the phone. So I want to use same source code(project) of 
AndARSample to install in the phone but different name like AndARSample2. 
Basically every application has own UID. So how i can change the UID/ID number 
of AndARSample application to use same source code/project but different name 
and different UID. 

My phone can install two application (AndARSample & AndARSample1) with same 
source code/project.How I can do this?

Thanks
