T152455 would be handy here.

gdb wait-for-devices complained with:

Your emulator is out of date, please update by launching Android Studio:
 - Start Android Studio
 - Select menu "Tools > Android > SDK Manager"
 - Click "SDK Tools" tab
 - Check "Android SDK Tools" checkbox

I have upgraded it with:

$ ssh jenkins-deploy@integration-slave-jessie-android
$ sudo su - jenkins-deploy
$ cd /srv/jenkins-workspace/tools/android-sdk
$ ./tools/android update sdk --no-ui  --filter tool,platform-tool

That error is gone.

There is some issue to bring up the emulator though :(

And with the API 25 image we're back to boot timeouts, it seems. That's an unpleasant surprise. Our longstanding timeout issues booting the API 24 emulator were fixed by adding the -no-window command line option to the launch command, but this one doesn't boot even with that flag set.

I tried unchecking "Show emulator window" in the web configuration UI and re-running, but that didn't help.

[integration/config@master] Bump Android periodic test to android-25

https://gerrit.wikimedia.org/r/366965

status update

The apps-android-wikipedia-periodic-test job is now configured to use android-25 to take snapshots. @Mholloway proposed two patches to update the Android Plugin which I have deployed them on the Jenkins master.

https://gerrit.wikimedia.org/r/#/c/366253/ to support a change in the system name introduced by android-25

https://gerrit.wikimedia.org/r/#/c/366965/ is the related CI config change to switch to android-25 and change the ABI from x86 to google_apis/x86 (fix found by @Mholloway

https://gerrit.wikimedia.org/r/#/c/366484/ get rid of the -engine classic which is QEMU1. There are a couple side effects:

• QEMU2 no more supports -no-audio, one has to pass QEMU_AUDIO_DRV=none. The CI change is https://gerrit.wikimedia.org/r/#/c/366908/

• the instance has four CPU and the build time went from ~45 minutes to ~11 minutes.

That finally address T158014: Investigate how to improve Android CI performance and stability !

The job currently fails due to screenshot differences. That is apparently not related to the platform or QEMU change.

Fix for screenshot differences (some legit, some questionable and needing review, some due to platform discrepancies) is here: https://gerrit.wikimedia.org/r/#/c/366991/.

Screenshots need updating again as a result of 31aedab. I'll get to that sometime today.

https://gerrit.wikimedia.org/r/366253

The job is now running with android-25 and QEMU 2 which make it run tasks in parallel.

We had to resort to forking the Android plugin. The patch are in our Gerrit and merged.

Co-Fixed with @Mholloway \O/

Once the screenshot tests are fast enough, I guess we will run them on every proposed patchsets and they will never regress :-]
