Hardware Testers needed

UltraMarine · March 13th, 2010, 09:28 AM

So Hey

I just wrote a simple multi-touch app
I need to test this to see if it work with multi touch on the real hardware.
and also to test if the bitmap fonts work.

if you're interested in digging the source code.

The red lines indicate the 1 pointer.
the blue which you can't see on the emulator is supposed to be the second pointer

BTW
you're doing this on your own risk.

The red crossing point (im guessing its supposed to be where your finger is) is off by about 1 square. Also the blue doesnt move. It comes up, but only the red still moves, you cant move both. I CAN see the 1.0 and 2.0 too. Motorola Droid

OH HEY THANKS.....

My Conclusion.
1. Bitmap loading works.
2. The function that takes care of the movement is in a for loop.
maybe I should remove the loop and do the whole thing one by one.

or maybe there's another way on how they do it..

But
Mucho Gracias!!

No problem, you got farther than I did

Ok about the red lines being 1 square off?
well that's weird.

In the Emulator I see that it's a couple of pixels off when it's near the top left corner.
but when it's down bottom, I see that it's almost correct.

Keeps force closing on my Sprint HTC Hero :/

hmmm.
I also coded it in Android 2.1
so what version of Android do you have noidea?

Yeah, everywhere on the screen it was about 1 block off to the right. I am running 2.0.1 fyi

ok this is how it comes out for the emulator......

Maybe the problem lies in GL.java and in Runner
( in public boolean onTouchEvent(MotionEvent event) )
I need to formulate a proper solution for this...

After a quick look at the source code..
I have removed these codes

Quote:

// float cx = control[0].tMove[0] + control[0].tDown[0];
// float cy = control[0].tMove[1] + control[0].tDown[1];

and replace it with these

Quote:

// float cx = control[0].tDown[0];
// float cy = control[0].tDown[1];

and it seems like Y axis is a little bit off. when it's near the Top/Left corner
But X axis seems to be alright.

and yes.
same goes with event.getY() and event.getY(int);...

after all the test.
is seems like it affects with these... (don't have an idea how to test cancel..)
// MotionEvent.ACTION_DOWN
// MotionEvent.ACTION_UP
// MotionEvent.ACTION_MOVE

even in rotated state.
it seems like I have this problem with the width that's 320 pixel wide.

updates again.

uninstall the old one.
please test what the values are when it's on the top/left corner
I need to know what the difference are
and please test if multi touch work.

no...

I found out where the bug is.
I'm using the wrong value for the height in ortho mode

ok for me on my droid eris running android 2.1 it works perfectly fine with just one finger but then it gets confused with 2 fingers and the blue line dosen't move at all.

Using Sprint Hero, running with a 2.1 ROM, the blue crosshairs don't appear at all.
Only single touch is being registered. The touch center is precise though. I don't see any drift.

And this is most likely a hardware issue with my device, but when pressing in the lower-left area of the screen, without moving my finger, the red crosshairs are unstable and shift around slightly. In the upper-right corner, the crosshairs remain solid.

(I flipped my phone around upside down just to make sure it wasn't one hand shaking and not the other, but I saw the same result. In one corner, the touch center would shift, but not the other.
