Hi,

Could you please give some more details, because am getting the same issue.

I have a button that will call back the cloudreco activity, by that time am getting "Failed to Initialize QCAR" error, whereas if i press the back button i wont get any error at all and the cloudreco activity loads.

Am not sure where to check for ImageTargets.jar. Please help.

Hello,

It sounds like you may not be pausing or de initializing qcar when switching activities. You should be calling QCAR.onPause() before switching the activity to retain the state, and then when returning to the activity call QCAR.onResume(). Please take a look at ImageTargets.jar in the ImageTargets sample app and see the onPause and onResume functions for the correct way to pause and resume QCAR.

Thank you,
