Is there Pause action For Download Manager in Android?

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 ?

Or Is there another way to do that ?

Edit: I found this way, It's working:

• When pause downloading process, close the file we wrote on.
• When resume downloading, access to the file (not completed) and get its size
• Add downloaded bytes info to the header of httpRequest : mHttpRequset.setHeader("Range", "bytes=" + mPreviouslyDownloadedBytes + "-");
• mHttpClient.execute(mHttpRequset);
