How we can Find cause of CTS Error?

I found some CTS errors which are given below:

Compatibility Test Case: CtsAppTestCases

Package Name: android.app.cts.DialogTest

Error:

This Test is expecting the lifecycle as onPause() then onStop(), but onResme() was called rather than onStop(). According to Android Activity Docs – “After receiving this call you will usually receive a following call to onStop() (after the next activity has been resumed and displayed), however in some cases there will be a direct call back to onResume() without going through the stopped state.” So, it is not mandatory to get desired sequence.
