Hi,
I wanna write an app to enable and disable the Bluetooth device
synchronized. Referring the Android source code, I registered
following receiver to receive the bluetooth state change event:
private static final String EXTENDED_BLUETOOTH_STATE_CHANGED_ACTION =
"com.android.settings.bluetooth.intent.action.EXTENDED_BLUETOOTH_STATE_CHANGED";
private final BroadcastReceiver mReceiver = new BroadcastReceiver
() {
@Override
public void onReceive(Context context, Intent intent) {
String action = intent.getAction();
if (action.equals
(EXTENDED_BLUETOOTH_STATE_CHANGED_ACTION)) {
Log.d(LOG_TAG, "bt state changed");
ContentResolver resolver = context.getContentResolver
();
// If bluetooth is currently expected to be on, then
enable or disable bluetooth
if (Settings.System.getInt(resolver,
Settings.System.BLUETOOTH_ON, 0) > 0) {
// do sth....
} else {
// do sth...
}
}
}
};
IntentFilter filter = new IntentFilter(
EXTENDED_BLUETOOTH_STATE_CHANGED_ACTION);
registerReceiver(mReceiver, filter);
But it doesn't work. Although the BT status has been changed (the icon
of BT has been appeared or disappeared), the receiver could not
receive nothing.
Could you give me any suggestion on this issue? It is tearing out my
hair.
Any reply will be appreciated.
Thanks,
Stanley
