Jonas Kulla The configure script didn't differentiate between Linux and Android, unconditionally compiling in the unix implementation of SDL_sysfilesystem.c. I'm probably one of the very few people building SDL for android using classic configure + standalone toolchain, so this has gone undetected all along.

/** \brief Allows back-button-press events on Windows Phone to be marked as handled
|
|
*
|
|
* Windows Phone devices typically feature a Back button. When pressed,
|
|
* the OS will emit back-button-press events, which apps are expected to
|
|
* handle in an appropriate manner. If apps do not explicitly mark these
|
|
* events as 'Handled', then the OS will invoke its default behavior for
|
|
* unhandled back-button-press events, which on Windows Phone 8 and 8.1 is to
|
|
* terminate the app (and attempt to switch to the previous app, or to the
|
|
* device's home screen).
|
|
*
|
|
* Setting the SDL_HINT_WINRT_HANDLE_BACK_BUTTON hint to "1" will cause SDL
|
|
* to mark back-button-press events as Handled, if and when one is sent to
|
|
* the app.
|
|
*
|
|
* Internally, Windows Phone sends back button events as parameters to
|
|
* special back-button-press callback functions. Apps that need to respond
|
|
* to back-button-press events are expected to register one or more
|
|
* callback functions for such, shortly after being launched (during the
|
|
* app's initialization phase). After the back button is pressed, the OS
|
|
* will invoke these callbacks. If the app's callback(s) do not explicitly
|
|
* mark the event as handled by the time they return, or if the app never
|
|
* registers one of these callback, the OS will consider the event
|
|
* un-handled, and it will apply its default back button behavior (terminate
|
|
* the app).
|
|
*
|
|
* SDL registers its own back-button-press callback with the Windows Phone
|
|
* OS. This callback will emit a pair of SDL key-press events (SDL_KEYDOWN
|
|
* and SDL_KEYUP), each with a scancode of SDL_SCANCODE_AC_BACK, after which
|
|
* it will check the contents of the hint, SDL_HINT_WINRT_HANDLE_BACK_BUTTON.
|
|
* If the hint's value is set to "1", the back button event's Handled
|
|
* property will get set to 'true'. If the hint's value is set to something
|
|
* else, or if it is unset, SDL will leave the event's Handled property
|
|
* alone. (By default, the OS sets this property to 'false', to note.)
|
|
*
|
|
* SDL apps can either set SDL_HINT_WINRT_HANDLE_BACK_BUTTON well before a
|
|
* back button is pressed, or can set it in direct-response to a back button
|
|
* being pressed.
|
|
*
|
|
* In order to get notified when a back button is pressed, SDL apps should
|
|
* register a callback function with SDL_AddEventWatch(), and have it listen
|
|
* for SDL_KEYDOWN events that have a scancode of SDL_SCANCODE_AC_BACK.
|
|
* (Alternatively, SDL_KEYUP events can be listened-for. Listening for
|
|
* either event type is suitable.) Any value of SDL_HINT_WINRT_HANDLE_BACK_BUTTON
|
|
* set by such a callback, will be applied to the OS' current
|
|
* back-button-press event.
|
|
*
|
|
* More details on back button behavior in Windows Phone apps can be found
|
|
* at the following page, on Microsoft's developer site:
|
|
* http://msdn.microsoft.com/en-us/library/windowsphone/develop/jj247550(v=vs.105).aspx
