I'm looking for something like ACRA (Automated Crash Reporting for Android) https://github.com/ACRA/acra but it has to be able to store data, and send it once the user goes online.
Already read through suggestions on
How do I obtain crash-data from my Android application?
but none of these says something about offline solutions. Anybody knows a solution that works offline and that I could use with my AWS account or a linux domestic server (raspberry pi)?
