Installs the given Android package (APK) file onto an Android emulator or device.

If an Android emulator was started automatically via the "Run an Android emulator during build" option above, the APK will be installed onto that device.

Otherwise, the APK will be installed onto an emulator or USB-attached Android device.
If more than one emulator or device is present, this step will currently hang until only one emulator or device is available — this is the default Android SDK behaviour.
