Sorry. I forgot to include the logcat details. Here they are:

Well, I figured this out. It is not the nativeSetImagePix that wasnt being 
accessed. There was a problem in reading the file in the readBitmap function 
because the bitmap wasnt in the ARGB_8888 format. 
This piece of code is required instead:
final TessBaseAPI baseApi = new TessBaseAPI();
        baseApi.init(TESSBASE_PATH, DEFAULT_LANGUAGE);
//        baseApi.setPageSegMode(TessBaseAPI.PSM_SINGLE_LINE);
        BitmapFactory.Options opt = new BitmapFactory.Options();
        opt.inPreferredConfig = Bitmap.Config.ARGB_8888;
        final Bitmap bmp = BitmapFactory.decodeResource(getResources(), R.drawable.digits, opt);
        ImageView img = (ImageView) findViewById(R.id.imageView1);
        img.setImageBitmap(bmp);
        baseApi.setImage(bmp);

• Changed title: Throw exception for unsupported Bitmap types
• Added labels: Type-Enhancement
• Removed labels: Type-Defect

Check already exists in ReadFile.readBitmap().
