I downloaded a file on to my Android phone. When I try to open the download, it goes to HTML Viewer and the only thing it says is "null". Will somebody tell me what this means and how I can view this file?
The phone is going to the HTML viewer because the file name ends with ".html" or one of the other extensions use by web pages. Or, put more simply, it thinks you've downloaded a web page.
Null may signify a zero length file. Perhaps the download failed?
