    I would use HTTP Lib for this task (http://www.basic4ppc.com/android/help/http.html). Init with the Url of your file and then use StatusCode As Int [read only]. When the Code is 200 the file will exist. I didn't tried this, it is just an idea how to start. may be there more easy or better solutions...

    Another workaround is to download the file in a try catch and then check if the file exists locally by using a timer.
    Would be rather effective for smaller files. Perhaps not the best solution but a working alternative.
