crashlytics initialization :

public class myapplication extends multidexapplication {   @override public void oncreate() {     super.oncreate();      fabric.with(this, new crashlytics());      if (!buildconfig.debug) {         log.d("ez", "release mode. crashlytics enable");         //fabric.with(this, new crashlytics());     } else {         log.d("ez", "debug mode. crashlytics disable");     }      throw new runtimeexception("this crash");     } } 

i fixed timeoutexception adding following build.gradle

ext.enablecrashlytics = true 

or if have several extensions already:

ext {     ...     enablecrashlytics = true }
