how can i use functions from androidController?

Can you describe what problem you are trying to solve rather than how you want to solve it?

i need to unlock the screen, but there a keygard screen. i can’t control the device. how can i disable the keygard?

If you are running locally, you can grant yourself access to adb to invoke the unlock app. See this discussion for details: Is it possible to open the lock by using appium in android?

I’m looking for ways to access androidController, but haven’t found them yet
