Unity Android Black screen

January 31, 2012 - 6:09am #1

Hello Qdevnet

I'm working on a project which uses Qualcomm AR for unity.
I'm using unity 3.4.2f with an android license.

The software used to function properly, however i had some issues in which the camera on the smatphone completely froze up and it required a telephone reboot, even the android camera app gave a black screen.
it occurs on mutiple devices: Samsung Google Nexus S, Samsung Galaxy S 2.

i have no idea what causes this crash and the only solution is to restore a backup and start over again, and in some cases it will run just fine after restoring a backup and applying the changes again.

is there anybody who could tell me what the problem is?
thanks in advance.

problem solved. the problem lay in the touchscript where the user had to press an AR object to start a certain feature.
the script crashed because of too many triggers.

im using qcar-unity-android-1-5-4-beta1.
The version on the nexus S telephone is 2.3.6 and the Galaxy S2 uses version 2.3.3
I installed all android SDK's on the computer as well.

Are you using QCAR 1.0.6 or the 1.5 beta? Also what Android OS versions are on your devices?

If it happens again please capture the log and send it to

. We'll take a look.

Thanks,
