Android example can not close on Escape

[Demir]

Hello,

I try to run android example through wiki "Tutorial: Building SFML for Android".
As was expected it worked.

I added Escape key release checking to close via Back button on the tablet.

if (event.type == sf::Event::KeyReleased)
{
  if (event.key.code == sf::Keyboard::Escape)
  window.close();
}
 

It can not close properly.
Any idea ? What can I do ?

Thanks

Edit:
I noticed same question at this link

Have you tried logging what key.code is actually generated? Maybe it's just not Escape as you expect but some other key code...

Returning key code is 36 it is Escape in "Keyboard::Key" enum.

On Escape It closes the example applicatin but after that .... the example app can not work again only black screen appears.

Make sure to leave your main() after you've closed the window. Any chance you forgot doing that?

I hope it gives you an idea to find close problem.
as I can see

std::exit(0);

can close completely.

1. I tried to control via isClosed boolean var. does not work

                if (event.key.code == sf::Keyboard::Escape)
                {
                    isClose = true;
                    window.close();
                }
 

2. I tried to return 0 does not work

window.close();
return 0;

From what I remember when working with iOS, you cannot actually close the application from within the application. Which makes sense if you think about it, the user needs to close the application via system supplied ways, i.e. pressing home button.

You can close app within code on iOS, but if so you have no chances for getting into appstore. And android applications often close themselves, so there must be some other error.

The only way to totally finish Android app is to call exit() or std::terminate() function. exit() is bad if you'll relaunch app immediately after exit. terminate() is bad because it shows popup window with error message (but it's rarely, tbh I saw it two or three times).
