Specifies whether or not we want to make use of a special build option in Android called MultiDex.
This enables building apps with over the limit of 64k methods (which can be reached easily when using many third-party extensions like Facebook, Twitter, etc).
The default value is True.
This feature avoids building error:
UNEXPECTED TOP-LEVEL EXCEPTION:
com.android.dex.DexIndexOverflowException: method ID not in [0, 0xffff]: 65536
