Also added native code to the Android gradle project, which allows using gradle or Android Studio to build the entire SDL application without a separate ndk-build step.

Some API 16 methods are used (InputDevice: getDescriptor(), getVibrator()), so we need to compile at least with SDK API 16. Hence default.properties and project.properties have been modified to use android-16.
There are also some modification to SDLActivity.java not to use getVibrator() if we run under API 16. And not to check to presence of hasVibrator() if we are under API 11.
-some hard-coded constant can be expandend.
- rename a local variable (hasVibrator to hasVibratorService)

NVidia has released some pretty nice Tegra profiling tools for their Android devices. The NVidia Tegra Graphics Debugger works by providing an interposer library that intercepts ES2 and EGL calls. You must link against these libraries.
Unfortunately, this quietly fails with SDL2 because libEGL and libGLES2 are dynamically loaded with dlopen().
NVidia offers a secondary approach to using the Tegra Graphics Debugger: root your device and install a global interposer library. Almost no devs will try this first if they don?t have a rooted device.
I propose an update to the Android readme that explains why the static linking approach recommended by NVidia doesn?t work.
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().
