Cannot Resolve Method setLatestEventInfo

Well below is a simple example of working with Notifications, go through it, hope it helps!

MainActivity.java

public class MainActivity extends ActionBarActivity {

    Button btnShow, btnClear;
    NotificationManager manager;
    Notification myNotication;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        initialise();

        manager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);

        btnShow.setOnClickListener(new View.OnClickListener() {

            @Override
            public void onClick(View arg0) {
                //API level 11
                Intent intent = new Intent("com.rj.notitfications.SECACTIVITY");

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

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

                builder.setAutoCancel(false);
                builder.setTicker("this is ticker text");
                builder.setContentTitle("WhatsApp Notification");               
                builder.setContentText("You have a new message");
                builder.setSmallIcon(R.drawable.ic_launcher);
                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);

                /*
                //API level 8
                Notification myNotification8 = new Notification(R.drawable.ic_launcher, "this is ticker text 8", System.currentTimeMillis());

                Intent intent2 = new Intent(MainActivity.this, SecActivity.class);
                PendingIntent pendingIntent2 = PendingIntent.getActivity(getApplicationContext(), 2, intent2, 0);
                myNotification8.setLatestEventInfo(getApplicationContext(), "API level 8", "this is api 8 msg", pendingIntent2);
                manager.notify(11, myNotification8);
                */

            }
        });

        btnClear.setOnClickListener(new View.OnClickListener() {

            @Override
            public void onClick(View arg0) {
                manager.cancel(11);
            }
        });
    }

    private void initialise() {
        btnShow = (Button) findViewById(R.id.btnShowNotification);
        btnClear = (Button) findViewById(R.id.btnClearNotification);        
    }
}

activity_main.xml

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >

    <Button
        android:id="@+id/btnShowNotification"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Show Notification" />

    <Button
        android:id="@+id/btnClearNotification"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Clear Notification" />

</LinearLayout>

And the activity that will be opened on click of Notification,

public class SecActivity extends Activity {

}

cannot resolve method `setLatestEventInfo`

'setLatestInfo` was removed in API 23: https://developer.android.com/sdk/api_diff/23/changes/android.app.Notification.html

You should use the Notification.Builder instead: https://developer.android.com/reference/android/app/Notification.Builder.html

There is an example here.

I am assuming you're using an outdated Android tutorial. Try to use the ones from https://developer.android.com. They're the most reliable.

Cannot resolve setLatestEventInfo method

I have tried the below, however, it says that it cannot resolve symbol contentintent.

That is because you failed to copy some lines from your original code into your revised code:

    Intent notificationIntent = new Intent(this,StartActivity.class);
    PendingIntent contentIntent = PendingIntent.getActivity(this, 0,
            notificationIntent, 0);

Have those in your revised code before you start configuring the Notification.Builder.

setLatestEventInfo() can not resolve in Android Studio

As see here setLatestEventInfo :

setLatestEventInfo method is removed from Notification class

To create Notification use Notification.Builder class as:

Notification.Builder builder = new Notification.Builder(MyRemiderService.this);
.....
builder.setSmallIcon(R.drawable. notification_template_icon_bg)
       .setContentTitle("ContentTitle")
       .....
       .setContentIntent(pendingNotificationIntent);

Notification notification = builder.getNotification();
notificationManager.notify(R.drawable.notification_template_icon_bg, notification);
