Description

MultiProcessSample in googlesamples/android-testing will crash occasionally.

And if change the private process to main process, repeat 100 times, will success.

Steps to Reproduce

Expected Results

Test success.

Link to a public git repo demonstrating the problem:

I have commit code of repeat the test 100 times in my repo.
https://github.com/shifujun/android-testing/tree/master/ui/espresso/MultiProcessSample

Inizia con MultiProcessSample ed esegui ExampleInstrumentedTest 100 volte sull’emulatore API 28 fornito, confrontando le configurazioni del processo privato e del processo principale. Segui il fallimento attraverso le chiamate segnalate di EspressoRemote.java e utilizza il repository di esempio collegato per riprodurlo. Il lavoro è completato quando il test multiprocesso ripetuto termina correttamente senza la IllegalStateException.
