title: Signed app crashing and unsigned apk running
body: <p>This issue might be related to some SO questions as i searched a lot here, but no any post helped me. My app running when it is unsigned but it crashes instantly when i run the signed APK. I put it <code>debuggable true</code> in gradle and checked i found this error logcat.</p>
