Sam Lantinga 047c19ce76 Fixed bug 2558 - Missing FINGERUP in Android
Sylvain

If you play with the TouchScreen with +3 fingers randomly / pressing simultaneously all fingers.

You triggers FINGER DOWN events, but not always all the associated FINGER UP events.

So, after a while SDL_GetNumFingers() can report a wrong number of fingers pressed !


The explanation is hidden there : http://developer.android.com/reference/android/view/MotionEvent.html

Each pointer has a unique id that is assigned when it first goes down (indicated by ACTION_DOWN or ACTION_POINTER_DOWN).
A pointer id remains valid until the pointer eventually goes up (indicated by ACTION_UP or ACTION_POINTER_UP) or when the gesture is canceled (indicated by ACTION_CANCEL).

in ACTION_CANCEL :

The current gesture has been aborted. You will not receive any more points in it. You should treat this as an up event, but not perform any action that you normally would.
Constant Value: 3 (0x00000003)

Simple DirectMedia Layer is a cross-platform development library designed
to provide low level access to audio, keyboard, mouse, joystick, and graphics
hardware via OpenGL and Direct3D. It is used by video playback software,
emulators, and popular games including Valve's award winning catalog
and many Humble Bundle games.

SDL officially supports Windows, Mac OS X, Linux, iOS, and Android.
Support for other platforms may be found in the source code.

SDL is written in C, works natively with C++, and there are bindings 
available for several other languages, including C# and Python.

This library is distributed under the zlib license, which can be found
in the file "COPYING.txt".

The best way to learn how to use SDL is to check out the header files in
the "include" subdirectory and the programs in the "test" subdirectory.
The header files and test programs are well commented and always up to date.
More documentation and FAQs are available online at:
