add this to gradle.build:

defaultConfig {
...
minSdkVersion 14
targetSdkVersion // your version 
...

// Enabling multidex support.
multiDexEnabled true
}

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

• follow android developers page's instruction: https://developer.android.com/studio/build/multidex.html
