@mayfu - Any news about this? Thanks!

I could confirm the test server is running on emulator (adb -s emulator-5554 shell am instrument -e with_uiautomator true -e main_activity.. ) but tests could not connect with this exception:

"It looks like your app is no longer running.
It could be because of a crash or because your test script shut it down."
