Android error "android.app.Application does not implement dagger.android.HasActivityInjector"

I solved my problem adding android:name in AndroidManifest.xml

If your implementation is correct then please check in manifest file if you have add/assigned the name of Application Tag.

 <application
    android:name=".base.BaseApplication"
    android:allowBackup="true"
    android:icon="@mipmap/ic_launcher"/>
