Touchscreen input with SDL2 bootstrap

[JonAnCla]

Is this meant to work? I can get my app to start and it renders as expected, but then I can't interact with it...

See app startup log below.

If there is something I can contribute to help wire this up let me know (and please point to where to start if possible!)

Thanks

Yes, it should work. It looks like your apk kivy is trying to load the android joystick provider, which was how touch was done with the old pygame bootstrap (and depended on the now-incompatible android module), but I'm not sure why

Do you find that touch doesn't ever work at all? I haven't tested it much, but it did work for me without issues (Kivy listens to the touch events internally via sdl2 when available). Either way, I guess the place to look is probably kivy's module loading, to see why it things AndroidJoystick should be loaded.

[Tungsteno74]

Someone is trying to solve the problem, or has already been solved in some dev version? Because i have done some test and I found something interesting as the cause of the problem.

[inclement]

I haven't been able to reproduce the issue, and haven't seen anyone else come across it either.

[Tungsteno74]

Thanks Inclement. Then I share what I discovered.
I think that most likely the cause of the problem do not lies in androidjoystick.py module (which is successfully skipped) but, there is a transparent layer that appears along with the image loading that locks the touch (I ask for a confirmation by some developers).
If for some reason (that I do not know) the loading image is properly removed but not the transparent layer, you will have the OP problem.
I think a similar thing happen with the Kivy app example Showcase. In practice, the application starts, the loading screen appears, but does not disappear anymore.
This problem does not always happen, then you have to do some tries.
Among other things, a minor problem is that the touch actions are activated while there is the loading screen, so they are buffered and then are triggered after the loading is complete.

Hi,
I hit exactly the same issue. It is possible that the transparent layer is not removed. I have the following line in the adb log:
I/PythonActivity(17060): Surface will NOT be transparent

Just to mention that I also have the problem "AndroidJoystick is not supported by your version of linux". Is there any progess on a solution?

[linziwen]

i just want to point out that scene that pygame depends sdl which conflit with sdl2,so if you want to use sdl2 as bootstrap,then you can not use pygame, but the joystick is one of the pygame module.
what a funny issue......

[inclement]

Getting the ImportError isn't necessarily a problem, does touch actually not work for you?

[linziwen]

actually the touch function works for me in this case. but i found another problem which is highly related to this issue. when i use bootstrap with sdl2 and i use pyjnius to making use of the java class, such as
"MediaPlayer = autoclass('android.media.MediaPlayer')" or something like that. my app will crash, whereas the pygame bootstrap won't.the logcat are not able to log anything just crash.

and when i compare the output of the logcat betwteen sdl2 and pygame , i found something strange as follows:

the line "08-06 15:43:11.691 2602 2625 I python : [WARNING] [Base ] Unknown provider" which i thought may be the source of the problem.

This issue is stale and I haven't seen anything about this recently, so closing.
