android-download-manager

问题 In my app you can download some files. I used the Android DownloadManager class for downloading. After the download is completed, it should show me a message that the file was downloaded.

Downloads are completing fine as long as the file size is less than 2 GB. I got stuck on a file that is 3.2GB in that I get progress updates (I am pooling the DownloadManager for progress updates), but when the download completes, the file is not present on the target file path. Interrogating the DownloadManager for that download id, I

问题 I'm using download manager class in android to download some files . This class can add and remove a request of downloading . Is there any way to pause a specific download then resume it ?

问题 I want to achieve that when downloading, it can be paused, stopped by user. How can I achieve this with DownloadManager? 回答1: You can remove a download from the queue. Then you can start it up again, passing the Range HTTP Header when re-adding it to the queue (like TryTryAgain mentioned). I don't believe this currently can be done more easily. 回答2: It may be that "pausing" isn't exactly necessary for you? As DownloadManager actually doesn't need to pause to be resumed.
