Updated Android build tools version, which bumped minimum deployment target to API 14
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.

Why is API level 10 the minimum required?
|
||||
Why is API level 14 the minimum required?
|
||||
================================================================================
|
||||
|
||||
API level 10 is the minimum required level at runtime (that is, on the device)
|
||||
because SDL requires some functionality for running not
|
||||
available on older devices. Since the incorporation of joystick support into SDL,
|
||||
the minimum SDK required to *build* SDL is version 16. Devices running API levels
|
||||
10-11 are still supported, only with the joystick functionality disabled.
|
||||
|
||||
Support for native OpenGL ES and ES2 applications was introduced in the NDK for
|
||||
API level 4 and 8. EGL was made a stable API in the NDK for API level 9, which
|
||||
has since then been obsoleted, with the recommendation to developers to bump the
|
||||
required API level to 10.
|
||||
The latest NDK toolchain doesn't support targeting earlier than API level 14.
|
||||
As of this writing, according to https://developer.android.com/about/dashboards/index.html
|
||||
about 90% of the Android devices accessing Google Play support API level 10 or
|
||||
higher (March 2013).
|
||||
about 99% of the Android devices accessing Google Play support API level 14 or
|
||||
higher (October 2017).
