Android minifyEnabled true causes app to crash

Question

When I generate an app bundle (release) with minifyEnabled true, when I install the app on a device and run it I get this error:

E/AndroidRuntime: FATAL EXCEPTION: main Process: xxxxxxxxxxxxx PID: 12723 lb at iahac.di(:39) at iahac.de(Unknown Source:10) at fsdi(:4) at lnkaaf(Unknown Source:8) at dai0.run(:2) at android.os.Handler.handleCallback(Handler.java:883) at android.os.Handler.dispatchMessage(Handler.java:100) at android.os.Looper.loop(Looper.java:214) at android.app.ActivityThread.main(ActivityThread.java:7356) at java.lang.reflect.Method.invoke(Native Method) at com.android.internal.os.RuntimeInit$MethodAndArgsCaller.run(RuntimeInit.java:492) at com.ZC31B32364CE19CA8FC D150A417ECCE58Z.internal.os.ZygoteInit.main(ZygoteInit.java:930)

NB: I edited the original question because Facebook was not the cause of the crash.

Answer 1

It's probably due to proguard rules that are not configured correctly. Check if it works when you add this to your proguard rules:

-keep class com.facebook.** {
   *;
}
