The class android.app.DownloadManager (Since: API Level 9) is a system service that handles long-running HTTP downloads. Clients may request that a URI be downloaded to a particular destination file. The download manager will conduct the download in the background, taking care of HTTP interactions and retrying downloads after failures or across connectivity changes and system reboots.
It's a basic code to download file from internet using DownloadManager.
Xml code:
"android.permission.INTERNET" is needed in AndroidManifest.xml.
