Yesterday I created a new feature, tapped 'stream' and verified that the system was actively recording GPS data by walking around the parking lot. Then I took off on my mountain bike to map some new trails for my community and the non-profit groups that make these trails possible. When I got back to the car, Collector was unresponsive - all that was shown under the blue banner with the name of the project was a spinning circle, the type of graphic that typically indicates that something is loading. When I pulled into my driveway 10 minutes later, the spinning circle was still there and the app was otherwise unresponsive. So I killed Collector and restarted it. I navigated to the project, but the line that I had attempted to record was completely absent, including the segment that I saw while in the parking lot.
Is it possible to recover the data from my phone? I have found the ArcGIS_Collector/offline_data folder, but it's empty. If it's not recoverable, what I can do to prevent this loss in the future?
I'm running a LG G2 with Collector 10.3
