Failed binder transaction when putting an bitmap dynamically in a widget

by

This is caused because all the changes to the RemoteViews are serialised (e.g. setInt and setImageViewBitmap ). The bitmaps are also serialised into an internal bundle. Unfortunately this bundle has a very small size limit.

You can solve it by scaling down the image size this way:

 public static Bitmap scaleDownBitmap(Bitmap photo, int newHeight, Context context) {

 final float densityMultiplier = context.getResources().getDisplayMetrics().density;        

 int h= (int) (newHeight*densityMultiplier);
 int w= (int) (h * photo.getWidth()/((double) photo.getHeight()));

 photo=Bitmap.createScaledBitmap(photo, w, h, true);

 return photo;
 }

Choose newHeight to be small enough (~100 for every square it should take on the screen) and use it for your widget, and your problem will be solved 🙂
