Question

I found out that different versions of android puts the received bluetooth files in different folder. For instance, one of my test phones running android 2.2 saves the files to this path:

/mnt/sdcard/Downloads/Bluetooth

and my second test phone, running android 4.0 saves the files here

/mnt/sdcard/Bluetooth

Is this operating system “issue” or is it set from the manufacture of the phone?

If the first statement is the correct can I check which version of android running, and the point to the bluetooth folder? Or is there a much simpler way to do this?

Thanks!

Answer 1

After some hours I made two methods for doing this. You should put the methods in a AsyncTask or a Thread. So here is my two methods:

public List<File> folderSearchBT(File src, String folder)
        throws FileNotFoundException {

    List<File> result = new ArrayList<File>();

    File[] filesAndDirs = src.listFiles();
    List<File> filesDirs = Arrays.asList(filesAndDirs);

    for (File file : filesDirs) {
        result.add(file); // always add, even if directory
        if (!file.isFile()) {
            List<File> deeperList = folderSearchBT(file, folder);
            result.addAll(deeperList);
        }
    }
    return result;
}

This is a recursive method which will add all folders in the src parameter into a List.

I use this method in this method here:

public String searchForBluetoothFolder() {

    String splitchar = "/";
    File root = Environment.getExternalStorageDirectory();
    List<File> btFolder = null;
    String bt = "bluetooth";
    try {
        btFolder = folderSearchBT(root, bt);
    } catch (FileNotFoundException e) {
        Log.e("FILE: ", e.getMessage());
    }

    for (int i = 0; i < btFolder.size(); i++) {

        String g = btFolder.get(i).toString();

        String[] subf = g.split(splitchar);

        String s = subf[subf.length - 1].toUpperCase();

        boolean equals = s.equalsIgnoreCase(bt);

        if (equals)
            return g;
    }
    return null; // not found
}

Hope this helps, guys!
