After update android studio and plugins, new built apk meets puzzling native problem when launch, I found armeabi/armeabi-v7a so files compressed from 200KB to 10KB. While
I had the same problem and what worked for me was to reset global Android studio settings as well as project specific. To do so I just done those steps:
Remove ~/.AndroidStudio2.2/ (on Linux), c:\user\yourname\.AndroidStudio2.2 (on Windows)
Do not import any settings when starting Android studio.
Probably not the most elegant way to solve this, but it works for me.
