Hello, we are a group of researchers that investigate the occurrence of flaky tests in Android.

We voluntarily ran your GUI tests 12 times and found that some tests pass or fail non-deterministically, which characterizes them as flaky tests [1]. Below we list each flaky test we found, and its number of failures.

• cleanLayout1Test - failed 1 time (stack trace)
• cleanLayout2Test - failed 1 time (stack trace)
• penAboutScreenTest - failed 8 times (stack trace)
• testLookupSetting - failed 8 times (stack trace)
• patternSearchWithFavoriteTest - failed 8 times (stack trace)

We ran these tests on a generic Android Emulator (AVD) with Android API version 28.

If you confirm this behavior, our suggestion is to add the @FlakyTest annotation on these tests. See https://developer.android.com/reference/androidx/test/filters/FlakyTest

If you wish for a repair proposal, please let us know.
