I see you enabled multidex, but not completely.

android {
    defaultConfig {
       multiDexEnabled true
    }
}

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

Also, if you didn't do it already, follow the steps in the doc to add multidex to your application class and manifest.
