Force a download manager not to manage downloads
Android has a "defaults"-system for handling predefined requests such as opening a URL or pressing the home button. If you go into Android's System Settings -> Apps -> Android Download Manager and scroll down to "LAUNCH BY DEFAULT", you should see a button to clear the defaults. The next time you open your chrome browser and tap on a URL that has the &lt;a download=""&gt; property, a screen should pop up, asking you to choose which application to use for downloading.
