Firebase Performance Monitor Issue With Support Lib 26.0.0

I am getting the below error in com.google.firebase.firebase-perf plugin. Caused by: java.lang.NoClassDefFoundError: android/support/v7/app/ActionBarActivity at com.goog

Solution 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.

Solution 2:

https://developer.android.com/reference/android/support/v7/app/ActionBarActivity.html

This class was deprecated in API level 24.2.0. Use AppCompatActivity instead.
