I have been unable to process any touch input events on my android devices. Keyboard input on the other hand works just fine. I have debugged it so far by putting a System.exit() statement in the onNativeTouch() function in SDLActivity.java which causes the program to exit as soon as the screen is touched. I then removed that statement and further debugged by adding exit(0); to Java_org_libsdl_app_SDLActivity_onNativeTouch in src/core/android/sdl_android.c which exited in the same fashion as the Java code. So it appears that SDL is receiving touch events. However, when I check with the following code I get nothing. Am I doing something wrong or missing something obvious?
if (SDL_PollEvent(&inputEvent))
{
int numTouch = SDL_GetNumTouchDevices();
logMsg ("numTouch = " +Ogre::StringConverter::toString(numTouch));
//exit(0);
Try changing your “if(SDL_PollEvent(…))” to "while(SDL_PollEvent(…))"
so that it checks all events and not just the first one.

Thanks for the tip but it didn’t fix the problem. I have debugged further and found why I am not getting the touch input events. In the function Android_OnTouch in src/video/android/SDL_androidtouch.c it hits the following code and returns.
if (!Android_Window) {
return;
}
I am assuming this is related to the fact that I use OGRE for my graphics rendering engine and it initializes the display. I have tried using SDL_CreateWindowFrom() on the OGRE window but this has no effect. Is there another way that I can pass the window to SDL so that it doesn’t fail here?On April 10, 2015 7:39:49 AM MST, Jonathan Dearborn wrote:

I have figured out the problem and come up with a solution. It appears that SDL does not currently implement SDL_CreateWindowFrom() on Android. So calling it instead of SDL_CreateWindow does nothing and Android_Window never gets set. I have implemented a basic SDL_CreateWindowFrom function for Android modeled after the ones for other platforms and now can receive touch input events. I will work up a patch later in case someone wants to include it in SDL.
