How to close a Windows Phone 8.1 app

In WP7 and WP8 I just needed to clear the backstack in a page, then press Back button and the app is closed. In WP8.1 I do Frame.BackStack.Clear(), press Back and the app just minimizes.. How to kill it with Back button?

Solution

  • You can add, in your main page definition: 

    Windows.Phone.UI.Input.HardwareButtons.BackPressed += HardwareButtons_BackPressed;

    Then 

    private void HardwareButtons_BackPressed(object sender, Windows.Phone.UI.Input.BackPressedEventArgs e)
{
    if (!e.Handled && Frame.CurrentSourcePageType.FullName == "YourApp.MainPage")
        Application.Current.Exit();
}

    Warning: As others said, you should not use this and let the system handle the app closure. For example, if you use the Application Insights, I found that they are not sent to Azure when in Release mode
