MultiDexApplication does not implement HasActivityInjector

I use New Android Injector with Dagger 2 by https://medium.com/@iammert/new-android-injector-with-dagger-2-part-1-8baa60152abe

Before MultiDex support App has worked.
I have added multidex support to app/build.gradle and AndroidManifest.xml.
After MultiDex support i have got error logcat by instaling on device

New Android Injector with Dagger 2 does not support MultiDex ?

Answer Source

Have ou declared your current Application as the android:name in application tag in AndroidManifest.xml?

In your case, you must use the one that extends multiDexApplication.
