How to get the serial for the emulator? If I use android.os.Build.SERIAL this works for real devices, but not for emulators :-( Contains "unknown" then - should be something like emulator-5554 - so I can use it in combination with "adb -s"
EDIT: my use-case: I have UserAcceptanceTests running on multiple devices / emulators attached. If a test fails on some device I make a screen-shot and want to be able to pull this one automatically - to do so I need to pass the serial from the instrumentation so i can pull the screenshot via adb.
