Hi,
minetest is atm on svn revision 5122. From what I see, there is a bug in source/Irrlicht/Android/CIrrDeviceAndroid.cpp, function CIrrDeviceAndroid::handleInput:
In line 491 of the file there is "device->postEventFromUser(event)". Then status is returned.
According to the docs in android_native_app_glue.h (from the android NDK), the onInputEvent function (which gets set to CIrrDeviceAndroid::handleInput) "Return 1 if you have handled the event, 0 for any default dispatching".
Code as of svn revision 5122 does not do this. Especially, we should ask lower level code for whether the event is handled or not. I believe that works by doing "status = device->postEventFromUser(event);" instead. Then we can tell the OS that we have handled specific keys, and others not.
I only believe that the code should be that way, I haven't tested it yet whether my proposed fix works for me.
[GLES branch bug] Not telling OS that key event was handled
Re: [GLES branch bug] Not telling OS that key event was hand
Okay I've tested my fix now and it does what it should, so the bug is really there, and I've already described the way to fix it.
