compile 'io.reactivex.rxjava2:rxandroid:2.0.1'
compile 'io.reactivex:rxandroid:1.1.0' 
compile 'io.reactivex:rxjava:1.1.3'    


compile 'com.squareup.retrofit2:retrofit:2.3.0'
compile 'com.squareup.retrofit2:converter-gson:2.3.0'
compile 'com.squareup.retrofit2:adapter-rxjava:2.3.0'
compile 'com.squareup.okhttp3:okhttp:3.9.0'

我有扩展 MultidexApplication 的应用程序类。

  defaultConfig {
    multiDexEnabled true
  }
}
