Answer 1

It seems you have a problem with Over 64K Methods and then tried to resolved it with multiDexEnabled true in build.gradle (app module). But you need to add more than:

1. add: compile 'com.android.support:multidex:1.0.0' in dependencies of build.gradle

2. Extends your Application class to MultiDexApplication. and add MultiDex.install(this); in onCreated method of Application class.

your issue should be resolved
