EXTRA_LAUNCHED_FROM_AA

Default intent extra key indicating the phone app was launched by Android Auto.

Used by MSDKSession and MSDKSurfaceCallback when launching the phone app from the AA session. The phone app reads this extra to detect AA-initiated launches and adjust its behavior (transparent theme, move to background).

App modules should reference this constant (or re-export it in their own constants file) to ensure the key matches between SDK launch code and app reading code.
