Hi Marko!

Unfortunately I was not able to reproduce this issue.
Could you please run a quick test on the radar component on your device by launching the following url using

architectView.load("http://goo.gl/V0APf");

These testcases create a radar as in the attached sample-snippet

Hi Andreas

All tests worked fine, but the issue remained on tests tc3 - tc6. When i lock my phone in the middle of these tests , and then try to return to app, it crashes with tihs message 04-23 19:44:05.046: A/libc(11767): Fatal signal 11 (SIGSEGV) at 0x00000004 (code=1), thread 11985 (Thread-34618)

I believe it has something to do with radar in combination with pois. When there are no pois (tc1 , tv2 or end of tests), locking is working just fine. 

 

 

Hi again,

When phone locks screen, activity's onStop is called wich is not implemented in ArchitectView's lifecycle. Maybe there should be ArchitectWebView.removeAllViews() in ArchitectView's onDestroy, since that hepled me before when my custom webview caused similar problem?

Thank you so much for the hint, I was now able to reproduce this issue.
We'll fix it in upcoming update.

Kind regards

Hi Andreas,

Do you have any  workaround to fix this issue ?

We are looking for buying wikitude for 2 of our applications and this is the very last point that we need to fix.

Hi Bertand,

Unfortunately there is no quick workaround for this. We will provide fix for that in upcoming update.
Maybe you can use direction indicators in your first release and add the radar component as soon as SDK 2.1 is available.

Kind regards,
Andreas

Hi,

 

When I can expect the RADAR to work? when are you releasing the 2.1?

 

Thank you,

Narendra

Sorry for late reply.

Wikitude SDK 2.1 became Version 3.0 and is available for download from June 16th onwards.

Have a look at the download page.

Kind regards,
Andreas
