Android 模拟器在 Gitlab CI 上失败

Question

I'm trying to run android instrumented tests on Gitlab CI on a remote linux machine, everything works fine until it runs the gradle task for the tests, it fail without any further information.

I should also mention that one out of ten times, it works.

Can you spot something wrong?

Here is my gitlab CI file:

Answer 1

As explained in this post https://githubmemory.com/repo/mingchen/docker-android-build-box/issues/58 , at the startup, the android system undergoes a lot of processes and may be busy when trying to install the apk. This would cause for example a ShellCommandUnresponsiveException .

To solve this I just added as recommended a sleep 180 after the line with adb shell input keyevent 82
