Error in loading eng.traineddata (3.01) using com.android.content.res.AssetManager() about tesseract-android-tools HOT 6 OPEN

One thing I left to mention is that the IOException comes out where 
in.read(bytes);..And the Exception will not occur when I use an image file in 
the place of eng.traineddata file and everything runs OK.

what's the packageResource in sentence:
InputStream in=packageResource.getAssets().open(DEFAULT_LANG+".traineddata");

I tried with
 InputStream in=getAssets().open(DEFAULT_LANG+".traineddata");
and it turns out alright.

  I put all the above codes into only one function in a separate class so that I have to pass Resources() object (here packageResource) from main Activity() class into the function.... I've tried both with getResources().getAssets().open(DEFAULT_LANG+".traineddata"); and getResources().openRawResource(R.id.eng);. ...Both of them gave the same IOException() on calling the in.read(bytes) function.

I've decided to put the "eng.trainedata" file bytes into an array of C++ file 
and embed into the compiled library file.But the file size is more than 3MB.I 
haven't tested but I'm worried about the performance issue.Any ideas please 
help!

You need to put your traineddata file in "asset/tessdata". Looks like thats 
where you are trying to copy from.

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");
