Android emulator fails on Gitlab CI

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:

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

Take a look at the documentation, the licenses part should be under the android part. So it should be like this:

Emulator: ERROR: detected a hanging thread 'QEMU1 main loop'. No response for 105001 ms

I use Gitlab CI for continuous integration. After every commit I have 3 jobs in the pipeline: debug, unitTests and instrumentedTests. But now instrumented tests failed because of the timeout. I added my gitlab-ci.yml file below
I've already tried downgrade android sdk versions, but no luck at all. Maybe there are some commands for yml-file that could fix the problem.
Also maybe somebody knows how to make all tests not failed for EMULATOR_VERSION > 22. 24 or higher never worked at all.

There are following factors:
looks like google dropped support of qemu engine and only ranchu is supported for now
sdk was partially updated but there are bugs in update process
While qemu is no more supported this concrete bug with hanging seems wouldn't fixed ever.
For switch to ranchu environment:
avoid using *default* platform for avd's, prefer *google-api*'s one (while ranchu kernel is missed in default platforms)
update sdk with --channel=4
Just in case it helped me.

Android Travis CI Error: Invalid --abi armeabi-v7a for the selected target

I have also tried to change the abi in the emulator to google_apis/armeabi-v7a to no avail. Also tried to add google_apis in the system image download. I have currently tried API_LEVEL 22, 27 and 28.
What is the issue here?

You can try ANDROID_ABI=arm64-v8ainstead of ANDROID_ABI=armeabi-v7a

I don't know if this is still relevant since it was asked 4 months ago, but I also just recently had this same issue. I tried many different things people suggested and none of it worked till I set it up this way:
language: android

Travis CI cant find our gradlew file

We are trying to integrate our android app with travis CI. But it always fails with cannot access ‘gradlew’: No such file or directory. We can run the gradlew script from our local computer and the file is tracked by git. What can the problem be?

Most of this is copy paste since this is the first project for us that are using Travis CI.
Our error:

This is how it works in my scripts:
