1092192 - Disable Exchange Services on Android 4.2 x86 emulator

Status: RESOLVED FIXED

(Testing :: General, defect)

Description

[Geoff Brown [:gbrown]]

Exchange Services spew lots of messages to the logcat on the 4.2 emulator. There is concern that it might be involved in some test failures, and probably no good reason to keep it running - let's disable.

I can probably run the emulator locally, go into Settings > Apps > all and disable Exchange Services, then use my local system image to update the one we use for tests. Is there another way? I'd prefer something I can do from a shell.

I honestly don't know. Also, I have no idea if this is really affecting tests. Only a desire to minimize other processes on the device while tests are running.

Is it a separate package that you can uninstall?

Locally, I see

chocho:gecko-dev nalexander$ adb shell pm list packages | grep exc
package:com.android.exchange

Not clear what that package covers and if that can be uninstalled.

According to the Totally Authoritative http://blog.burrowsapps.com/2014/03/what-android-apps-are-safe-to-remove.html (a site that I just googled), com.android.exchange can be uninstalled safely.

$ adb uninstall com.android.exchange
Failure
$ adb shell
root@android:/ # pm uninstall com.android.exchange
Failure
root@android:/ #


Disabling in app settings seems to work okay.

We only run xpcshell tests on x86 now, and they have been running very reliably, so I am reluctant to make any changes now.

This may be implicated in dumpsys timeouts seen in experimental mochitest-chrome tests - bug 1315749.
