(Android) historyPos out of range

Post by FrankLiemar » Wed Nov 13, 2013 8:48 am

I am having the same problem as the owner of the topic below.
www.teechart.net/support/viewtopic.php?f=10&t=13275
As answer on the last question in the topic.
It seem to happen when i touch 2 different places in the chart very fast after each other.
I was able to reproduce the problem on your example app.
I am getting this problem on the Motorola Xoom and the Motorola Xoom 2.
android version : 4.0.4

Hello,

Thanks for the info. I have tried to reproduce this unsuccessfully here with a Nexus 4 and a Nexus 7 (2012). What I do is opening one of the examples in the demo and start touching the chart very quickly with one finger and also tried with multi-touch. Is this what I am supposed to do? Could you provide more detailed instructions on how to reproduce it? Should I touch on a series or anywhere on the chart? Any specific series?

Thanks in advance.

Update :
I am able to reproduce the problem everytime by touching and not releasing the chart with my index finger (with your whole finger not with the top of your finger).
I tested it on the Line and Bar chart.

Hello,

Thanks for the update. Both Nexus devices tested use Android 4.3. I also tried with a Motorola Defy (Android 2.1) and Samsung Galaxy Ace (Android 2.3.6) but worked fine there as well. Will keep investigating.

I have been searching for some answers .

there is a chance that you are calling the following code in your onTouch;

Code: Select all

event.getX()
which is probably causing errors
.
I can't see any Source Code so i wouldn't know.

Thanks for your help.

Hello,

I have checked the spam folder but it is not in there.

Also is there a way to disable the OnTouch event of the chart.
So that i can temporary disable the cursor tool untill the problem is fixed.
Because if i disable the cursor tool the ontouch still remains.

If you want to reproduce the problem you should really get a Motorola Xoom tablet.
I think that the problem is only for some of the tablets.
So that you need to change something only for those tablets.

After our apps released to Google Market, we also found this issue through customer feedback.
Even I haven't get a chance to reproduce, the crash log message is almost the same as posted here.

Hello eoinoc,

Do you know in what devices it was reproduced, and in what devices not?

No I don't.
But I don't think it's a device-specific problem.

This wouldn't explain why we can't reproduce the problem here following the same steps some customers indicated us, in the same demo application. The only difference we found was on the devices. Do you have any other clue?

I understand you haven't been able to reproduce the problem, but if you are aware of any step-by-step instructions we can follow to reproduce the problem in any device, please, don't hesitate to tell us.
