Android Never Call Method Oncreatethumbnail

Post a Comment
Based on Android documentation, method onCreateThumbnail is called before pausing the activity, and should draw into outBitmap the imagery for the desired thumbnail in the dimensio

Solution 1:

It is not possible to customize the activity thumbnail which system uses in the recent apps preview.

The method onCreateThumbnail had been broken since Android 4.0.3, when its call was commented out (see the source code).
