Signed Apk Crashes With Facebook Login

My Signed apk crashes first time on facebook login with this error: AndroidRuntime: FATAL Exception: main com.facebook.aq: com.facebook.c.f got an unexpected method signature: pub

Solution 1:

I guess you're using proguard. Facebook SDK sources are open. No need to obfuscate them. We added this rule to our proguard.cfg file: -keep class com.facebook.** { *; }
