Weird problem when loading AR scene

December 4, 2014 - 3:15am #1

Hi,

When I load an ar scene on my phone, i got a black screen.

But i noticed that the target recognition is still working : I'm able to see 3d object when targeting my ImageTarget. I also noticed that if I close and reopen the app, I got a black screen until the app recognize a target, since the app works perfectly. But if I close and reopen my app a third time, it always freeze and the app crash.

Another weird thing is the fact that if I target an ImageTarget before the loading, I don't have the black screen. But it crash directly when I close and reopen it.

That bug happens ONLY if i install my app from the Play Store. It works fine if I install the app manually. Please note that I have to split my app because of the size ( > 250Mo).

I got that bug on Samsung Galaxy S5, Xperia and LG G3.

I know that the bug may not come from Vuforia SDK, but if you have some hint, that would be great.

Oh and btw, sorry for my bad english

Chances are that the issue may be related to that. There might be something wrong in the app code when you try to extract the data from the Obb extension package.

Looking at device logs would probably be a good starting point to nail down the issue..
