1425334 - Give root permissions to adbd when running emulator unit tests

Status: RESOLVED FIXED

(Firefox for Android :: Testing, enhancement)

Description

[Geoff Brown [:gbrown]]

A lack of adbd root permissions results in a variety of errors when running a modern Android emulator environment (sdk 26, android 7.0).

$ adb shell ls /data/local
ls: /data/local: Permission denied
$ adb root
$ adb shell ls /data/local
tmp


We already try to use 'adb root' in android_emulator_unittest.py, but it does not always work because we try to use it too early:

Attachment: restart adbd after emulator has connected

This fixes this issue on trial runs with Android 7 on an arm emulator.

It doesn't break any existing jobs:
