Hi.
I wanted my application to know when the bluetooth of the device is turned
on and when it has been turned off.
I register the receiver intentfilter
IntentFilter i = new IntentFilter();
i.addAction(BluetoothAdapter.ACTION_STATE_CHANGED);
bluetooth_manager.registerReceiver(receiver, i);
in the receiver objects class, I wrote this:
String action = intent.getAction();
if (BluetoothAdapter.ACTION_STATE_CHANGED.equals(action)) {
Log.d(TAG,"Bluetooth State Changed");
String state = intent.getStringExtra(BluetoothAdapter.ACTION_STATE_CHANGED);
Log.d(TAG,"State: "+state);
}
When I turn my bluetooth on or off, my log shows me Bluetooth State Changed.
But the State always comes a null.
Can someone help?
