I have a music player app that plays music on my device using MediaPlayer. It will play through my device's speakers, but I can tap the device Settings App and turn Bluetooth on, then tap Bluetooth and pair or connect to my Bluetooth speakers, headphones, car player etc. and play though them.
I would like to be able to turn the device Bluetooth on and select the Bluetooth speakers etc. by tapping a button in my App instead of having to leave the app and use the device's buttons.
