Answer 1

Add this to your file build. gradle

defaultConfig {
     multiDexEnabled true 
}

Answer 2

The Android plugin for Gradle available in Android SDK Build Tools 21.1 and higher supports multidex, so you have to add multiDexEnabled true to your gradle file like below :

android {
    compileSdkVersion 21
    buildToolsVersion "21.1.0"

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

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

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