How do I get the Android DD app?

Daft question maybe… but how do I exit the DD app on Android?
I cannot for the life of me find any way to exit it. DD prevents me from starting DJI Go 4, the only way to get back to DJI Go is by restarting my phone.

Unfortunately you have to go to the multi-window view and swipe the app to close it. If that still interferes then you have to go into settings and force the app to stop.
