Question

I am setting an imageview to an image from the sd card. This runs smoothly on the android emulator 4.1, however on the emulator with android version 2.2 it returns a failed binder transaction. I find this very odd and can not figure out what the problem could be. The image image is set the following way:

               try{
                    String pathName = Environment.getExternalStorageDirectory().getPath() + "/Drop Insight/" + c.getString(iID) + ".png";
                    File path = new File(pathName);
                    if(path.exists()){
                        BitmapFactory.Options options = new BitmapFactory.Options();
                        Bitmap bm = BitmapFactory.decodeFile(pathName, options);
                        remoteView.setImageViewBitmap(R.id.ivwidgetimage, bm);
                    }
                    else{
                        remoteView.setImageViewResource(R.id.ivwidgetimage, R.drawable.defaultpic);
                    }
                }
                catch (Exception e) {
                    Log.e(DEBUG_TAG, "Failed", e);
                }

I have already tried options.inSampleSize = 4; but that did not solve the problem.

Thanks for any explanations and help.

For code like yours, this usually means that the bitmap is too large. You are limited to 1MB per Binder-based IPC transaction. I am not aware that this limit was raised in Android 4.x, though that is certainly possible.

Hence, make sure that setImageViewBitmap() uses a small enough Bitmap.
