Android notification is not opening activity
<p>I have a simple activity where I create a notification. When notification is clicked, it should open another activity. However, the Resualt activity doesn't start. Where did I make a mistake? Thank's for any help. </p>

<p>MainActivity:</p>

<pre><code>public class MainActivity extends Activity {
Button btnShow, btnClear;
NotificationManager manager;
Notification myNotication;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    Button notif = (Button) findViewById(R.id.notif);
    manager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
    notif.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            showNotif("09364415580", "hello!", getApplication());
        }
    });

}
public void showNotif(String from, String body , Context con) {

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

    PendingIntent pendingIntent = PendingIntent.getActivity(MainActivity.this, 1, intent, 0);

    Notification.Builder builder = new Notification.Builder(MainActivity.this);

    builder.setAutoCancel(false);
    builder.setTicker(body);
    builder.setContentTitle(from);
    builder.setContentText(body);
    builder.setSmallIcon(R.drawable.searc);
    builder.setContentIntent(pendingIntent);
    builder.setOngoing(true);
  //  builder.setSubText("This is subtext...");   //API level 16
    builder.setNumber(100);
    builder.build();

    myNotication = builder.getNotification();
    manager.notify(11, myNotication);

}

<p>ResualtActivity: </p>

<pre><code>public class Resualt extends Activity{
    @Override
    public void onCreate(Bundle savedInstanceState, PersistableBundle persistentState) {
        super.onCreate(savedInstanceState, persistentState);
        setContentView(R.layout.resualt);
        Toast.makeText(getApplicationContext(),"hi ! hi ! hi ! " , Toast.LENGTH_LONG).show();
    }
