If your minSdkVersion is set to 21 or higher, all you need to do is set multiDexEnabled to true in your app-level build.gradle file, as shown here:

android {
    defaultConfig {
        ...
        minSdkVersion 21 
        targetSdkVersion 25
        multiDexEnabled true
    }
    ...
}

However, if your minSdkVersion is set to 20 or lower, then you must use the multidex support library as follows:

Modify the app-level build.gradle file to enable multidex and add the multidex library as a dependency, as shown here:

android {
    defaultConfig {
        ...
        minSdkVersion 15 
        targetSdkVersion 25
        multiDexEnabled true
    }
    ...
}

dependencies {
  compile 'com.android.support:multidex:1.0.1'
}

Create an Application class like this:

public class MyApplication extends MultiDexApplication {
  @Override
  protected void attachBaseContext(Context base) {
     super.attachBaseContext(base);
     MultiDex.install(this);
  }
}

Add this application class in Manifest.

    
        ...
