   For example:

   public class MainActivity extends AppCompatActivity {
       @Override
       protected void onCreate(Bundle savedInstanceState) {
           super.onCreate(savedInstanceState);
           setContentView(R.layout.activity_main);
           setShowWhenLocked(true);
       }
   }
   

2. On the Knox Guard console, go to Policy, then click Application installation.

3. Click Browse and select the app you want to display.

   

4. Click Save.

5. Back on the Policy page, click Lock screen > Advanced control.

6. Under Advanced support methods, select Make an application available.

7. Click Import. The app package name and signature fields are automatically filled.

   

8. Click Save.

The app is now visible on the lock screen of the device when locked with Knox Guard.
