I have already tried using

-libraryjars /libs/unity-classes.jar
-keep class com.unity3d.** { *; }
-dontwarn com.unity3d.**

in the proguard-project.txt , still the same, how to fix it? Thanks for helping

Tried even

-keep class com.** { *; }

still the same

Answer 1

See an earlier question on Proguard errors with unity-classes.jar.

This is an issue with the classes in the Unity library: some of the preverification metadata are corrupt. You should check if there is a more recent version. Otherwise, you could modify ProGuard to accept the corrupt classes, as discussed on its issue tracker.

Note that you should not add -libraryjars or -injars to your configuration. The Android build process (Ant, Eclipse, Gradle) already specifies those options for you.

Answer 2

Try add this in your proguard-project.txt:

-keep class com.unity3d.** { *; }
-keep class org.fmod.** { *; }
