Question

I’m using a fileBrowser to find the files on the phone, but I wanted to show all files that my app can open to the user, and then the user chooses one. Like the Music Player, that show all songs on phone, on the sdcard and in the internal memory, not only the ones in the folder where the user is.

Answer 1

Use file name filters while listing out the files. The below sample lists out all mp3 files in a given root directory (Note – The below code doesn’t do it recursively for all folders under root) –

String files[] = root.list(audioFilter);

FilenameFilter audioFilter = new FilenameFilter() {
    File f;
    public boolean accept(File dir, String name) {
    if(name.endsWith(".mp3") || name.endsWith(".MP3")) {
            return true;
        }
        f = new File(dir.getAbsolutePath()+"/"+name);

        return f.isDirectory();
    }
};
