Android App crashes on release with proguard

Question

My App crashing when I create a release build. The app was working correctly and all of a sudden this happened. I have this line in BaseActivity.java MultiDex.install(this); I have tried multiple options from SO but none of them worked. The error is also not providing enough details or I am not able to locate the point where this issue is occurring. Any help would be greatly appreciated.

Here is stack trace.

Answer 1

from here

remove below lines from your proguard file

#1 to
-assumenosideeffects class * implements Interface {
    public <init>();
    public Object interfacemethod(); # May concern methods with same signature in other Objects
}
#end

And Replace

-assumenosideeffects class android.util.Log{*;}

With

-assumenosideeffects class android.util.Log {
   public static *** v(...);
   public static *** d(...);
   public static *** i(...);
   public static *** w(...);
   public static *** e(...);
   public static *** wtf(...);

}
