Dont think you need to use reflection here.

Try to

1) Set-up the mocked ContentResolver

2) Expect certain method called on LauncherServerCallback

@Test
public void testDeleteUser() throws Exception
{
    // Arrange
    Launcher launcher = new Launcher();
    Mockito.doReturn(1).when(contentResolver).delete(UserProvider.CONTENT_USER_URI, null, null);

    // Act
    launcher.deleteUser(contentResolver,launcherServerCallback);

   // Assert
   Mockito.verify(launcherServerCallback).onSuccess(Mockito.anyString());
}

You may also need to add this to kick-off the Mockito engine:

@Before
public void init(){
   MockitoAnnotations.initMocks(this);
}

Tip: you shouldnt test private methods. So either try to increase the visibiilty or move that code into a separate class.
