Display detailed upload progress in notification #155
Description
It was intended from the start to have detailed upload progress notifications for individual files.
- bytes sent / bytes total
- moving average bitrate
- moving average ETA
There are 2 major blockers to enabling this.
The first thing that needs to be solved is this issue in the Java SDK. filestack/filestack-java#51 The base SDK was supposed to provide the necessary progress updates for this, as a stream of progress objects from the upload observable, but that isn't working. And looking at the code now, I did not understand how parallelism was working in RX. So that all needs to be sorted out but I think the idea of the RX interface is fine, it's just not straightforward to have RX be parallel. (I still might be really lacking in RX understanding here.)
The other thing is that the UploadService needs some work. The IntentService won't work with non-blocking code. If we subscribe to an observable for the upload, we won't be blocking, and the service would just quit. So instead of an IntentService we need a base Service or maybe something else. And more recent versions of Android have introduced tougher restrictions to prevent battery draining (there's now a job scheduling system, JobIntentService, other things I've skimmed in press releases) so we should conform to that.
