Incoming call broadcast receiver

问题

I have registered incomingCall broadcast receiver, and it works fine, but I need receiver when the call is established (or rejected). What I actually need is something to notify me when the user press 'Answer' or 'Reject' call.

You can override your onReceive method of BroadcastReceiver as below

public void onReceive(Context context, Intent intent) {

    String state = intent.getStringExtra(TelephonyManager.EXTRA_STATE);

    if (state.equals(TelephonyManager.EXTRA_STATE_RINGING)) {
        //Phone is ringing
    } else if (state.equals(TelephonyManager.EXTRA_STATE_OFFHOOK)) {
        //Call received
    } else if (state.equals(TelephonyManager.EXTRA_STATE_IDLE)) {
        //Call Dropped or rejected
    }
}
