Can anyone give a simple example of the usage of PhoneStateListener?
I have tried to overwrite the listener and register it with the
TelephonyManager with the Context.TELEPHONY_SERVICE.
But i only saw my logging statement printed out right when I started
to run the application. The logging showed the PhoneState as IDLE.
But then after that when I use telnet to emulate an incoming call, I
don't see the logging statement been printed for PhoneState - RINGING
or PhoneState - OFFHOOK.
here is my code snippet:
TelephonyManager tm =
(TelephonyManager)this.getSystemService(Context.TELEPHONY_SERVICE);
tm.listen(this, CallStateListener.LISTEN_CALL_STATE);
public void onCallStateChanged(int state, String incomingNumber)
{
switch(state)
{
case TelephonyManager.CALL_STATE_DLE:
Log.d(DEBUG, "PHONE STATE - IDLE");
break;
case TelephonyManager.CALL_STATE_OFFHOOK:
Log.d(DEBUG, "PHONE STATE - OFFHOOK");
break;
case TelephonyManager.CALL_STATE_RINGING:
Log.d(DEBUG, "PHONE STATE - RINGING");
break;
}
}
