maratische android startmusicandnavigation

You can start playing music by one click. (by default you need start Spotify and after click on play)
My app starts spotify, waites before spotify will be ready playing, starts playing last song and after run spotify app or navigation app. (you can select one time)

while spotify is started in background, you can select playlist

I created it for my car multimedia system, because I want listening music and use navigation without click on car buttons
