Problem of starting game from EmulationActivity with extra "GamePath" directly

[allenz8512]

It seems something happen cause Choreographer is null in OnResume() which make app crash，it's normal when start the app first before calling am start, but this means it can't be support by emulator frontends.

Here's the log:
