You have too many methods. There can only be 65536 methods for dex.

As suggested you can use the multidex support.

Just add these lines in the build.gradle:

android {

    defaultConfig {
        ...

        // Enabling multidex support.
        multiDexEnabled true
    }
    ...
}

dependencies {
  compile 'com.android.support:multidex:1.0.0'
}

Also in your Manifest add the MultiDexApplication class from the multidex support library to the application element

    <?xml version="1.0" encoding="utf-8"?>
    <manifest xmlns:android="http://schemas.android.com/apk/res/android"
        package="com.example.android.multidex.myapplication">
        <application
            ...
            android:name="android.support.multidex.MultiDexApplication">
<!--If you are using your own custom Application class then extend -->
<!--MultiDexApplication and change above line as-->
            android:name=".YourCustomApplicationClass">

            ...
        </application>
    </manifest>

override attachBaseContext method

@Override
protected void attachBaseContext(Context newBase) {
    super.attachBaseContext(newBase);
    MultiDex.install(this);
}

If you are using your own Application class, change the parent class from Application to MultiDexApplication.

Another solution is to try to remove unused code with ProGuard - Configure the ProGuard settings for your app to run ProGuard and ensure you have shrinking enabled for release builds.
