I need to implement Download-Manager with pause and resume mechanism.
This manager is needed for downloading large video files or any other type.
I thought about using Android's DownloadManager, but as far as I know the DownloadManager doesn't support a manual pause and resume by the user.
What other Android build-in options do I have except for writing this component myself? Or maybe one knows how to use DownloadManager with manually pause and resume?
You would have to implement it yourself, bearing in mind that the server needs to support resuming. When the server does, it can be sent a request parameter in order to tell it where to resume sending the data from.
See the following SO question for an example of how to implement this.
Check out this open source, they claim to have implemented pause/resume, haven't tested it yet though.
