File dialog crashes with NullPointerException if dirPath does not exists.

I offer this solution:

    private void getDirImpl(String dirPath) {

        File f = new File(dirPath);
                // Use root directory if dirPath does not exists
        if(!f.exists())
        {
            Toast.makeText(context, "There is no such directory " + dirPath, duration).show();
            dirPath = root;
            f = new File(root);
        }

        myPath.setText(getText(R.string.location) + ": " + dirPath);
        currentPath = dirPath;

        item = new ArrayList<String>();
        path = new ArrayList<String>();
        mList = new ArrayList<HashMap<String, Object>>();

        File[] files = f.listFiles();

Такие дела =)
