Closed freshNfunky closed 7 years ago

freshNfunky commented 7 years ago

I am havong another problem with the area descriptions. It's the same problem as postet on G+ but mentioned to be a Zenia core problem: https://plus.google.com/102908861368834422170/posts/LH6yEcVojxt

the List of the ADFs is incomplete. When debugging the app via Android Studio -> Android Monitor the app also prompts the error: 02-07 19:47:13.954 7221-7243/?

it's a bit odd because on some builds it works without error and in others the error appears again. The most stable Configuration with the Developer Kit is: Building with mono2x and Gradle. With the internal or IL2CPP it's so far permanent. I am building with Unity 5.5.0p4

This will happen only on the TangoCore on the DevKit tablet. An app that does not properly connect to the Tango Service will revert to the legacy service and will cause Area Descriptions to only be accessible to the legacy service. This was done to avoid breaking existing apps.

The legacy service is not available on the Phab2 Pro or future Tango devices.
