phoneStateListner is Not properly work android

gistfile1.txt

I'm confused for my PhoneStateListner Class. Because this is for full caller Id photo Application.

In than I'm open Service at the time of incoming call/ Missed call/ received call. But this is only work at first time.

Context c;
boolean cut, flag = true;
PhoneStateListener listener;
SharedPreferences prefs;
static boolean ring = false;
static boolean callReceived = false;

public MyPhoneStateListener(Context c) {
    // TODO Auto-generated constructor stub
    this.c = c;
}

@Override
public void onCallStateChanged(int state, String incomingNumber) {
    super.onCallStateChanged(state, incomingNumber);

    Log.d("main", "incoming call receiver.");
    PowerManager pm = (PowerManager) c
            .getSystemService(Context.POWER_SERVICE);
    boolean isScreenOn = pm.isScreenOn();

    switch (state) {
    case TelephonyManager.CALL_STATE_IDLE:
        Log.v("idle state", "CALL_STATE_IDLE");
        // CALL_STATE_IDLE;
        if (ring == true && callReceived == false && CheckMissCall.isReject==true) {

            Log.v("missed call", "Missed call from : " + incomingNumber);
            if(CheckMissCall.isShown)
            {
                c.stopService(new Intent(c, Unlock_hud.class));
            }
            flag = true;
            Intent inter = new Intent(c, MissCall.class);
            inter.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
            inter.putExtra("CellNumber", incomingNumber);
            c.startActivity(inter);
        }


        break;
    case TelephonyManager.CALL_STATE_OFFHOOK:
        // CALL_STATE_OFFHOOK;
        callReceived = true;
        Log.v("call received", "CALL_STATE_OFFHOOK  " + incomingNumber);

        break;
    case TelephonyManager.CALL_STATE_RINGING:
        ring = true;
        // CALL_STATE_RINGING
        Log.v("call ringing", "CALL_STATE_RINGING  " + incomingNumber);
        Log.d("flags", "flags: " + flag);
        if (flag) {

            //cut = true;
            //flag = false;
            CheckMissCall call = new CheckMissCall(c);
            call.setName(incomingNumber);
            call.setNumber4Sms(incomingNumber);
            call.setContactPhoto();

            Log.d("main", "state ringing");
            prefs = PreferenceManager.getDefaultSharedPreferences(c);

            if (!prefs.getBoolean("main_state", false)) {

                return;
            }

            if (CheckMissCall.isRunning) {

                return;
            }
            else {
                Log.d("main", "EEEEEEEEEEEEEEEE:  Unlock hud");
                Intent in = new Intent(c, Unlock_hud.class);
                in.setFlags(Intent.FLAG_ACTIVITY_PREVIOUS_IS_TOP);
                c.startService(in);


            }
        }
        break;

    }
    
    
    Also when I cut call after received. The missed call screen is not call.

I am confused about this thing. can any one edit my code please.
