Facebook App Event sdk 4.38.0 throws NPE in ViewHierarchy.setAppearanceOfView










10















I'm having a problem in one of my apps where I use facebook sdk. After upgrading sdk from 4.27.0 to 4.38.0 fabric started to log this fatal exception. I don't know when or how it happens cause i can't reproduce it myself. Maybe some of you had this problem after upgrading facebook SDK.

  • To reproduce the case you can just create ImageView and set empty BitmapDrawable: imageView.setImageDrawable(new BitmapDrawable()); imageView.setClickable(true); Then Facebook SDK in ~2% cases (currently) based on device id will enable button indexing feature and it will fail because BitmapDrawable.getBitmap can be null.
