Android API 26 SecurityException issue

In my app I have a fragment and an imageButton inside of this fragment. When I run the app in my device (Android 8 - API 26) and click imageButton, the app crashes and throws a runtime error which I didn't see before.

E/AndroidRuntime: FATAL EXCEPTION: main
              Process: com.example.mustafa.diyetisyenadmin, PID: 26366
              java.lang.SecurityException: Permission Denial: null asks to run as user 1 but is calling from user 0; this requires android.permission.INTERACT_ACROSS_USERS_FULL or android.permission.INTERACT_ACROSS_USERS

So I added the required permissions in Manifest.xml and also tried every codes in the topic Android permission.INTERACT_ACROSS_USERS_FULL but I get the same error. I have solved Autofill problem with this topic but in that fragment error occurs just only I clicked ImageButton. What should I do to solve this problem?

Finally I found out the solution. Problem occurs since I had a method in my activity named getUserId() that returns String user_id and send data to fragments. I changed it's name and now everything works fine.
