The android emulator launcher script is mainly used in CI and thus makes sense to be moved there. This also makes it easier to make changes without having to wait for submodule updates. The env var ANDROID_EMULATOR_RUNNER points to the path of the runner script, and can be used by qtbase. qt5.git part of the change. Task-number: QTQAINFRA-5596 Change-Id: If253e0a5f14d67526995561b1859312e61efdfff Reviewed-by: Alexandru Croitor <alexandru.croitor@qt.io>

# minute the boot animation starts spinning (bootanim=running) again despite
|
|
# boot_completed=1 all the time. After some minutes the boot animation stops
|

# again and the list of packages contains 80 packages. Only then the device is

# fully booted, and only then is dev.bootcomplete=1.
