Changing ImageView content causes OutOfMemoryError

Question

I have a very simple application with one ImageView and a Button. The first Drawable resource loaded by my ImageView is specified with the \"android:src\" tag i

Answer 1

Seems like before loading a new Bitmap I had to recycle the Bitmap displayed by the ImageView, now it is working without a problem. Hope this helps someone else, just call the folowing method before setting the new ImageView's content.

((BitmapDrawable)imageView.getDrawable()).getBitmap().recycle();

so the code now looks like this:

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data){
    super.onActivityResult(requestCode, resultCode, data);
    switch(requestCode){
        case INTENT_REQUEST_SELECT_IMAGE:
            if(resultCode==Activity.RESULT_OK){
                Uri selectedImageUri = data.getData();
                Log.i(TAG,"selectedImageUri.getPath()"+selectedImageUri.getPath() );
                ImageView imageView = (ImageView) this.findViewById(R.id.ImageView_of_text);
                ((BitmapDrawable)imageView.getDrawable()).getBitmap().recycle();
                imageView.setImageURI(selectedImageUri);
                imageView.invalidate();

            }else{
                //TODO define what to do in case the user canceled OCR or any other event
            }
            break;
        default:
            break;
    }
}

Please note the call to recycle on the Bitmap of the ImageView.
