* Don't fail silently if the AVD name is not provided.
* Add the following flags to the emulator:
* -no-window: since we don't really interact with emulator is CI
* -no-boot-anim: no need to run the boot animation
* -no-snapshot-load: removed because it serves nothing
* -detect-image-hang -restart-when-stalled: helps recover the
emulator from freezes during execution
* Disable warning dialog about nested virtualization.
* Terminate the emulator instance if the script expects it to not be
running, i.e. save time by attempting to terminate and move on with the
script execution instead of simply failing and doing nothing.
* Add a timeout to the blocking call 'adb wait-for-device'
* Save logcat output to a file for quick access to the logs,
and put both emulator and logcat files under testresults folder,
which would them available in cases of failure without needing to
create a VM for debugging to get the logs.

# list packages` shows only 16 packages installed), and after around half a
|
|
# 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
