Android: app crashed when starting after signing in release mode

问题

Currently I am facing an issue of app crashing when starting after signing in release mode, but in debug mode it worked fine.

I could not figure out the problem right now, even though i did research and keep look for solutions but i still not managed to make it works

When the app crashed it doesn't show in my app logcat but shown in "No Filter"

The errors was

java.lang.NoSuchFieldError: NO_ACTION

ProGuard

-dontwarn retrofit.**
-dontwarn okio.**
-dontwarn com.squareup.okhttp.**

回答1:

Your problem is that proguard is renaming your code and that you're using reflection.

The easiest fix would be to disable proguard (set minifyEnabled to false in your build.gradlefile).

If you want to keep proguard enabled, you need to add -keep yourclass in your proguard rules file. Example if I want to keep the Activity class:

-keep class android.app.Activity

If I want to keep all the android.app package:

-keep class android.app.**

More informations on proguard here.
