Due to Google's policies ( search web for "Android text relocations" ) we cannot distribute x86 package with full FFmpeg optimizations enabled through Google Play anymore, the known workarounds for this would break other features and affect more users than this does - x86 users are a tiny minority according to Google Play.

As a workaround, I provide a standalone download for the APK - compiled with full optimizations, but without bleeding edge Android SDK.

To avoid Google Play from overwriting this version with a newer but unoptimized build, you might want to disable Google Play automatic updates.
