Hello,

I am able to successfully build and run the samples but i cannot get a bare-bones AR application working.  The app starts, the wikitude splash fades in and out but the camera never starts.  In the console i see the following errors:I/OpenGLRenderer:

D/libEGL: eglInitialize EGLDisplay = 0x9c7ff3cc

if (theArchitectView != null)
{

try

}

Any help is greatly appreciated.

 

thanks,

ok i figured it out.  For anyone else that has this problem there are two ways to fix it.  For me, the simple way was to just downgrade the targetedSkVersion to 21.  There was a tooltip i hadn't noticed in the AndroidManifest.xml that indicated the <uses-sdk> tag is ignored in favor of what's specified in gradle build script.  I didn't realize this was the case so that tag is not helpful so i had to just adjust the build and that did the trick.  the second way is to use the new permissions approach which you can see detailed here:  https://inthecheesefactory.com/blog/things-you-need-to-know-about-android-m-permission-developer-edition/en
