Augmented Reality demo does not connect to Tango Service after onPause #31

Open nuernber opened 9 years ago

nuernber commented 9 years ago

If you press the button for "recent apps", thus causing onPause() to be called, and then go back to the app, thus causing onResume() to be called, the application does not successfully connect to the Tango Service again. It shows the AR graphics but no camera frames.

Here's the output of the logcat:
