I am using the following libs :
- com.google.firebase:firebase-plugins:1.1.1
- com.google.firebase:firebase-perf:11.0.4
- Support lib 26.0.0
- build tool version 26.0.1
*fyi : It is working fine below support lib 26
回答1:
We were facing similar issue. It was one of the libraries which was causing this issue. That library was still using ActionBarActivity in their code. It worked fine after removing that library.
EDIT: Alternatively, you can create a proxy class in your project. Create a class named ActionBarActivity under same package name as it is there in support library and make it extend AppCompatActivity class.

https://developer.android.com/reference/android/support/v7/app/ActionBarActivity.html
This class was deprecated in API level 24.2.0. Use AppCompatActivity instead.
