Getting Weird Nullpointer Exception Proguard

Fatal Exception: java.lang.NullPointerException at com.x.c.l.d(ProGuard:713) at com.x.c.e.c(ProGuard:161) at com.x.b.a.a(ProGuard:41) at com.x.b.a$1.run(ProGuard:646)

Solution 1:

I think this code was injected by a malware (Xposed etc) or your app was hacked, repackaged and published elsewhere. I receive the same crashes. If you looked into stack traces from other threads you would very likely find there an ad serving code. I did find it, unfortunately.
