How to detect hangup of an incoming call which was not answered.?

I found many questions those are describing how to get the call state of a phone call using telephonymanager .And I was following this question in stackoverflow - How to detect when phone is answered or rejected. But this is to detect the various phone states separately. I need to add a alert dialog only when a incoming call hang up with out answered. How to detect this particular event.?

Android 5.0 and above may send duplicate events. You may consider keeping the previous state for comparison -

private class PhoneStateChangeListener extends PhoneStateListener {

static final int IDLE = 0;
static final int OFFHOOK = 1;
static final int RINGING = 2;
int lastState = IDLE;

@Override
public void onCallStateChanged(int state, String incomingNumber) {
    switch(state){
        case TelephonyManager.CALL_STATE_RINGING:
             lastState = RINGING;
             break;
        case TelephonyManager.CALL_STATE_OFFHOOK:
             lastState = OFFHOOK;
             break;
        case TelephonyManager.CALL_STATE_IDLE:
             if (lastState == RINGING) {
                 // Process for call hangup without being answered
             }
             lastState = IDLE;
             break;
    }
}
}

Try the below code:

private class PhoneStateChangeListener extends PhoneStateListener {
boolean isAnswered = false;
@Override
public void onCallStateChanged(int state, String incomingNumber) {
    switch(state){
        case TelephonyManager.CALL_STATE_RINGING:
             isAnswered  = false;
             break;
        case TelephonyManager.CALL_STATE_OFFHOOK:
             isAnswered=true;
             break;
        case TelephonyManager.CALL_STATE_IDLE:
             if(isAnswered == false)
             //Call hangup without answered
             break;
    }
  }
}
