If you upload your dot wav file to SoundCloud.com it will convert the file to a format useable for playing here. It does require that you sign up for a SoundCloud account ( it's free ). After it converts the uploaded file, it will provide a URL link that you can post here. This is what HJ suggested and the test that I successfully performed. Else, see if there is an Android app that will convert your file to an MP3.
The beauty of the SoundCloud procedure is that the sound file will play here as an embedded file ( no need to download ).
