Query the natively compiled-in subsystems at runtime so the Java side
only registers and initializes the managers that exist, fixing
UnsatisfiedLinkError when SDL is built with a subsystem disabled
(e.g. -DSDL_AUDIO_DISABLED).
- Add SDL.setupJNI(int subsystems) plus SDL_INIT_* Java constants;
SDLActivity passes an overridable getInitSubsystems() mask so custom
activities can skip Java-side setup for unused subsystems.
- Distinguish compiled from requested subsystems: JNI registration
follows nativeGetCompiledSubsystems(), while manager initialization
and surface/layout creation follow the requested-and-compiled mask.
- Gate HIDDeviceManager.acquire() (USB/BLE device scanning) on a new
nativeIsHIDAPIEnabled() query so HIDAPI-less builds never touch it.
- Gate SDLControllerManager.initializeDeviceListener() and the
joystick key-event path on the controller subsystem; gate the
clipboard handler on video, mirroring the native guards.
- Guard the SDLControllerManager JNI bindings with
SDL_ANDROID_NEED_CONTROLLER_MANAGER (joystick or haptic enabled).
- Skip layout updates in ShowTextInputTask when no layout exists
(video disabled).
- Reorganize SDL_android.h/.c into guarded per-subsystem groups with
matching ordering.
Now it does _not_ call SDL_SetError(), since that would allocate memory with
the system in a weird state, and setting all four functions to NULL will
restore the original memory functions, as a shortcut vs having to query
SDL_GetOriginalMemoryFunctions() first.
Fixes#15914.
If a device has disconnected, and the app has quit the audio subsystem before
the queued main thread function has run, the pointer will be bogus by the time
the run occurs. So now it looks up the object from its device ID, and if the
lookup returns NULL, it returns immediately and everything works out.
Reference Issue #14856.
(which might be fixed by this or not.)
`Wayland_CreateAnimatedCursor` calls `SDL_qsort` on an array of
type `**SDL_Surface`, not on an array of `*SDL_Surface`. As such the void
pointers in the callback need to be casted to `SDL_Surface **` not
`SDL_Surface *`.
This was likely not caught since it's very unlikely that reading a few
bytes past the end of this array results in reading unreadable memory,
so the only side effect was invalid sort results, which is a bit subtle.
I caught this because I build SDL with UBSAN enabled in my debug builds,
and it trapped when the multiplication of the garbage `SDL_Surface*`
width and heights overflowed. I validated that the change is correct by
adding logs (that have then since been removed) demonstrating that it
was previously comparing garbage, and is now comparing the actual cursor
surfaces.
These functions already return immediately for NULL objects in normal builds, but it was done through CHECK_PARAM. When building with SDL_DISABLE_INVALID_PARAMS, these checks were compiled out, and NULL resources could reach backend release functions and cause segfault.
Always return on NULL so API behaves consistently regardless of SDL_DISABLE_INVALID_PARAMS.
The event coordinates returned by GetMessagePos() for WM_NCACTIVATE are out of date if the cursor moved while an overlay was active, and may indicate that the cursor is still in the window when it is not. Always use the current cursor coordinates when processing this message to avoid incorrectly setting mouse focus if the cursor is no longer within the window.
Add AndGAMER/Void Gaming USB IDs for Void GENESIS.
Recognize the Void GENESIS SInput VID/PID pair and set its device name.
Add DirectInput gamepad mappings for the wired and dongle DirectInput modes.
Allow Android embedders to use SDL without the full video/audio Java
layer by gating subsystem-specific code behind SDL_VIDEO_DISABLED and
SDL_AUDIO_DISABLED preprocessor flags.
This enables applications that only need joystick/gamepad support
(e.g. Qt-based apps like QGroundControl) to build SDL without shipping
stub Java classes for unused subsystems.
Changes:
- Split SDLActivity JNI method table into core (lifecycle, hints,
permissions) and video (surface, input, clipboard, orientation)
- Gate SDLAudioManager and SDLInputConnection JNI registration
- Make checkJNIReady() subsystem-aware: no longer requires
mAudioManagerClass when SDL_AUDIO_DISABLED
- Group method ID resolution by subsystem in nativeSetupJNI()
- Guard all video/audio function implementations and declarations
- Keep display orientation accessors always available (needed by camera)
- Add subsystem-selective SDL.setupJNI(int)/initialize(int) to SDL.java
with backwards-compatible zero-arg overloads
- Guard SDL_VIDEO_DRIVER_ANDROID and related defines in
SDL_build_config_android.h
SDL has no dummy fallback for the RTC functions, and the PS2 implementation is just an empty dummy implementation, so rename it and build it if no system-specific time functionality is found.
