Description

On Android KitKat (API level 19) without Google Play Services, AES-GCM does not work properly. This is because KitKat uses Bouncy Castle 1.48 which does not support updateAAD.

If Google Play Services is present, AES-GCM should work well.

If you want to support all Android versions without depending on Google Play Services, use CHACHA20-POLY1305, AES-EAX, or AES-CTR-HMAC-AEAD.
