Discover this:https://github.com/mihaip/dex-method-counts Tools show you libs that have many methods. Your dependency in graddle so huge, are you really using all of it? If no try to delete unused

Answer 2

Android newer build tools have support for mutidex. you can enable multidex support by editing your build.gradle file like below

  defaultConfig {
        ...
        minSdkVersion 14
        targetSdkVersion 21
        ...

        // Enabling multidex support.
        multiDexEnabled true
    }

Also you have @override this method in your Application class

protected void attachBaseContext(Context base) {
 super.attachBaseContext(base);
 MultiDex.install(this);
}
