MainActivity

public class MainActivity extends Activity {

   

      final static int NOTI_ID = 50;

      

      Button btnNoti;

      //Notification을 관리해준다.

      NotificationManager notiManager;

      

    @Override

    protected void onCreate(Bundle savedInstanceState) {

          super.onCreate(savedInstanceState);

          setContentView(R.layout.activity_main);

         

          btnNoti = (Button) findViewById(R.id.bt_noti);

          btnNoti.setOnClickListener(listener);

          //notification 초기화

          notiManager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);

         

    }

   

    private void notiStart(){

      

      //생성될 인텐트의 컨택스트 ,이동할 컨택스트

      Intent intent = new Intent(MainActivity.this, SecondActivity.class);

      intent.putExtra("str", "value");

      //앱이 꺼저도 노티가 유지될 수 있도록 하는 기능

      PendingIntent pendingIntent = PendingIntent.getActivity(MainActivity.this, 0, intent, 0);

      

      Notification notification = new Notification.Builder(MainActivity.this)

            .setSmallIcon(R.drawable.ic_launcher)

            .setTicker("Noti Message")

            .setContentTitle("Noti Title")

            .setContentText("Noti Content")

            //노티 시간설정 여기서는 즉시 적용된다.

            .setWhen(System.currentTimeMillis())

            .setContentIntent(pendingIntent)

            .build();

      //notification에 유니크한 아이디값을 주어 관리한다.

      notiManager.notify(NOTI_ID, notification);

      

    }

   

    OnClickListener listener = new OnClickListener() {

            

            @Override

            public void onClick(View v) {

                  // TODO Auto-generated method stub

                  switch (v.getId()) {
