@matyasatfp: I see, backgroundSessionConfigurationWithIdentifier: is available from iOS8. On iOS7 it should use deprecated backgroundSessionConfiguration:. You can either do a pull request with the fix or wait untill I can do this.

Thanks for the hint, we fixed it in our fork:

https://github.com/funkypandagame/BackgroundTransfer-ANE/commit/45ab3e42e163d037e1108410f78ceab1a0979860

Sadly I cant make a PR since the commit turned out to be a bit messy, but feel free to copy the code.
