I made a sample project using ndk + openGL. Idea of the app is simple, open the camera when you tap on the screen AR object appear on place where you tapped.
When I worked in debug mode all was ok, but after I switched in release mode, compilation is ok, I can open the camera, but when I tap on the screen the app crashed.
Of course there any logs... So, to open the logs option (in order to find out the reason of the crash) I added such line debuggable true in release section.
But, now when I tap on the screen the app don't crash...
What is the possible reason of crash? How can I check it if I get crash only with debuggable false and can't see logs...?
Here my gradle
apply plugin: 'com.android.application'
