Android Exception when using 3D option in chart

[froggyware]

Hi,

We are getting the following error message when creating a 3D Chart on Android 4.0.4

We are able to reproduce this on a HTC ONE S running android 4.0.4

Any Ideas?

I just tested on the same hardware with android 4.1.1 and it works.

clearly an android 4.0.4 problem. Nasty,

Not sure how to work around it.

Hello,

I don't get any error with the v4.0.3 emulator. It may be some important step I could be missing to reproduce the problem. Could you please try to reproduce the problem in a simple example project and in an emulator?

Hi,

I can confirm that everything is working fine in the emulator with 4.0.3.

For the moment I put in place a work around and just disable the 3D option for SDK 15.

Looks like the bug is only reproducible on physical devices. We have many crash reports from different customers, so its not an isolated problem, but more widespread. Looks like really a OS level problem.

Hello,

Thanks for sharing your progress.
Does the workaround presented at StackOverflow work fine for you?

Hi,

I tried the solution and attempted to disable the hardware acceleration, but this had no effect. I still got a FC.
Looks like some device / OS Combinations are the problem. HTC is certainly an issue as we have these in the office.
I spent one day on it now looking for a solution, but was not successful.

It's not a show stopper for us as we just decided to disable 3D charts in this version of Android. Seems effort vs result is not positive. We leave it out
