If Bluetooth is paired and connected manually, get the connected device:

1. Check the connection status:

Java code
    1. int A2DP = Bluetoothadapter.getprofileconnectionstate (BLUETOOTHPROFILE.A2DP);
    2. int headset = bluetoothadapter.getprofileconnectionstate (Bluetoothprofile.headset);
    3. int health = bluetoothadapter.getprofileconnectionstate (bluetoothprofile.health);

2, depending on whether there is a connection to obtain the connected device:

Java code
  1. int flag =-1;
  2. if (A2DP = = bluetoothprofile.state_connected) {
  3. flag = A2DP;
  4. } Else if (headset = = bluetoothprofile.state_connected) {
  5. flag = headset;
  6. } Else if (health = = bluetoothprofile.state_connected) {
  7. Flag = health;
  8. }
  9. if (flag! =-1) {
  10. Bluetoothadapter.getprofileproxy (mainactivity. This, new Servicelistener () {
  11. @Override
  12. public void onservicedisconnected (int. profile) {
  13. //TODO auto-generated method stub
  14. }
  15. @Override
  16. public void onserviceconnected (int. profile, Bluetoothprofile proxy) {
  17. //TODO auto-generated method stub
  18. list<bluetoothdevice> mdevices = Proxy.getconnecteddevices ();
  19. if (mdevices! = null && mdevices.size () > 0) {
  20. For (Bluetoothdevice device:mdevices) {
  21. LOG.I ("W", "Device name:" + device.getname ());
  22. }
  23. } Else {
  24. LOG.I ("W", "mdevices is null");
  25. }
  26. }
  27. }, flag);
  28. }
