i trying receive notifications when connection state changed "connecting,connected,disonnectig,disconnected". registered action_connection_state_changed, receive log in "default" statement of "switch-case".

please let me know how receive notified correctly regarding states mentioned in switch-case in below code?

code:

final int connstate = intent.getintextra(bluetoothadapter.extra_connection_state, bluetoothadapter.error);              switch (connstate) {             case bluetoothadapter.state_connected:                 log.d(tag, logand.show("onreceive", "bluetoothadapter.state_connected"));                 tvstatus.settext("bt state_connected.");                  break;             case bluetoothadapter.:                 log.d(tag, logand.show("onreceive", "bluetoothadapter.state_connected"));                 tvstatus.settext("bt state_connected.");                  break;             case bluetoothadapter.state_connecting:                 log.d(tag, logand.show("onreceive", "bluetoothadapter.state_connecting"));                 tvstatus.settext("bt state_connecting.");                 break;             case bluetoothadapter.state_disconnecting:                 log.d(tag, logand.show("onreceive", "bluetoothadapter.state_disconnecting"));                 tvstatus.settext("bt state_disconnecting.");                 break;             case bluetoothadapter.state_disconnected:                 log.d(tag, logand.show("onreceive", "bluetoothadapter.state_disconnected"));                 tvstatus.settext("bt state_disconnected.");                 break;             default:                 log.wtf(tag, logand.show("onreceive", "connstate: unhandeled case."));                 break;             }             break;

you need

bluetoothadapter.extra_state

instead of

bluetoothadapter.extra_connection_state
