You could also switch the channels of the image in GIMP or Pohotoshop. Probably won't become faster than that.

In Topic: GLSurfaceView lag/delay

Here's another lag video. The delay between OS (CyanogenMod) and app seems to be less than in your video.






You mentioned in your video that the second example would not have delay, but imho the black line is still way slower than your finger (and where did the touch position indicator go?). Also this app would be way easier to program with Canvas, because Paint supports antialiasing.


I can't check Stealh Bastard because I don't have the game, but it does not look very prone to delay.

I noticed that even the default CyanogenMod UI has some delay, so it either is a hardware issue or OS issue.

Further I found two more threads which appear to be about the same problem, no solution through:



It is mentioned that there should be less lag on HTC devices, and I read somewhere else that iphones should have less lag, too.



Seems like not even the developers are sure what the reason is.


Anyway, unless we hack into android we can't change it.

I noticed the same thing (input lag when using GLSurfaceView) on a samsung galaxy s2 with android 2.3.3 or something around that weird version number.

If you use the Canvas element for painting instead you have less input lag, so it might be possible that the other apps you checked which didn't have input lag were not using OpenGL.

I suspect it's either double buffering or maybe I caught the touch events at the wrong place.

Anyway, I still have to check if this is still the case on non-stock android roms.

There's an irc channel #gamedev on freenode (approximately 130 people currently and quite active)
