83cb2b63	2016-10-14T06:57:55	Fixed bug 2758 - Android issues with NDK r10c and API-21 Sylvain After a long time, I found out more clearly what was going wrong. The native libraries should be built with a "APP_PLATFORM" as low as possible. Ideally, APP_PLATFORM should be equals to the minSdkVersion of the AndroidManifest.xml So that the application never runs on a lower APP_PLATFORM than it has been built for. An additional good patch would be to write explicitly in "jni/Application.mk": APP_PLATFORM=android-10 (If no APP_PLATFORM is set, the "targetSdkVersion" of the AndroidManifest.xml is applied as an APP_PLATFORM to the native libraries. And currently, this is bad, because targetSdkVersion is 12, whereas minSdkLevel is 10. And in fact, there is a warning from ndk: "Android NDK: WARNING: APP_PLATFORM android-12 is larger than android:minSdkVersion 10 in ./AndroidManifest.xml".) to precise what happened in the initial reported test-case: Let say the "c" code contains a call to "srand()". with APP_PLATFORM=android-21, libSDL2.so contains a undef reference to "srand()". with APP_PLATFORM=android-10, libSDL2.so contains a undef reference to "srand48()". but srand() is missing on devices with APP_PLATFORM=android-10 (it was in fact replaced by srand48()). So, if you build for android-21 (where srand() is available), you will really have a call to "srand()" and it will fail on android-10. That was the issue. The path tried to fix this by in fact always calling srand48(). SDL patches that were applied are beneficial anyway, there are implicitly allowing they backward compatibility of using android-21 on a android-10 platform. It can be helpful in case you want to target a higher APP_PLATFORM than minSdkVersion to have potentially access to more functions. Eg you want to have access to GLES3 functions (or other) of "android-21". But, if dlopen() fails (on android-10), you do a fall-back to GLES2.
0e45984f	2015-06-21T17:33:46	Fixed crash if initialization of EGL failed but was tried again later. The internal function SDL_EGL_LoadLibrary() did not delete and remove a mostly uninitialized data structure if loading the library first failed. A later try to use EGL then skipped initialization and assumed it was previously successful because the data structure now already existed. This led to at least one crash in the internal function SDL_EGL_ChooseConfig() because a NULL pointer was dereferenced to make a call to eglBindAPI().

An existing hint lets apps that don't need the timer resolution changed avoid this, to save battery, etc, but this fixes several problems in timing, audio callbacks not firing fast enough, etc. Fixes Bugzilla #2944.

b88ca1b4	2015-02-10T16:28:56	the last parameter of XChangeProperty is the number of elements.. and when the element format is 32.. the element is "long" so we have 5 long elements here. Yes this seems confusing as on mac+linux Long is either 32 or 64bits depending on the architecture, but this is how the X11 protocol is defined. Thus 5 is the correct value for the nelts here. Not 5 or 10 depending on the architecture. More info on the confusion https://bugs.freedesktop.org/show_bug.cgi?id=16802
b48e54aa	2015-01-26T22:00:29	Fixed bug 2802 - [patch] Fix android build compiling in wrong filesystem implementation 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.
70438be2	2014-12-03T10:55:23	WinRT: fixed bug whereby SDL would override an app's default orientation WinRT apps can set a default, preferred orientation via a .appxmanifest file. SDL was overriding this on app startup, and making the app use all possible orientations (landscape and portrait). Thanks to Eric Wing for the heads up on this!

24c86b55	2014-09-11T19:24:42	[X11] Reconcile logical keyboard state with physical state on FocusIn since the window system doesn't do it for us like other platforms. This prevents sticky keys and missed keys when going in and out of focus, for example Alt would appear to stick if switching away from an SDL app with Alt-Tab and had to be pressed again. CR: Sam

4349cb57	2013-10-10T21:51:39	Fixed bug 2146 - Enable static linking of libSDL on Android Denis Bernard This patch to Android.mk adds support for static linking of libSDL for Android applications. A patched readme with static build instructions is also provided. It does not break existing build environments setup according to the README-android.txt since the static library version will not be built in not required. The static build uses the Android NDK module system (see docs/IMPORT-MODULE.html in the NDK folder and step 5 in the instructions below). Instructions: 1. Copy the android-project directory wherever you want to keep your projects and rename it to the name of your project. 2. Create a symlink to SDL/src/main/android/SDL_android_main.c as <project>/jni/src/SDL_android_main.c 3. Rename <project>/jni/src/Android_static.mk to <project>/jni/src/Android.mk (overwrite the existing one) 4. Edit <project>/jni/src/Android.mk to include your source files 5. create and export an environment variable named NDK_MODULE_PATH that points to the parent directory of this SDL directory. e.g.: export NDK_MODULE_PATH="$PWD"/.. 6. Edit <project>/src/org/libsdl/app/SDLActivity.java and remove the call to System.loadLibrary("SDL2") line 42. 7. Run 'ndk-build' (a script provided by the NDK). This compiles the C source Although this requires an environment variable to be setup, it can be added once and for all to the main Android.mk of the project.
