Question

The code below is not executing. I’m calling it as NameManager.main(fsitem); from my main class. Not even debug is showing up in stack trace and it does not create the file. What am I doing wrong?

public class NameManager {
...
public static void main(ArrayList<String> fsitem) {
    for (int i = 0; i < fsitem.size(); i++) {
        try {
            File root = new File(Environment.getExternalStorageDirectory()
                    .getName() + "/" + fsitem.get(i));
            if (root.canWrite()) {
                if (!root.exists()) {
                    Log.d("NameManager.java",
                            (root.getName() + " exists and is writable."));
                    File namefile = new File(root, ".name");
                    FileWriter namewriter = new FileWriter(namefile);
                    BufferedWriter out = new BufferedWriter(namewriter);
                    out.write("image_"
                            + (i++)
                            + "%n(Autogenerated Name)[e-mail]");
                    out.close();
                } else {
                    Log.d("NameManager.java : ",
                        (root.getName() + " already exists."));
                }
            }
        } catch (IOException e) {
            Log.e("NameManager.java : ",("Error!! Not Writable!!"
                    + Environment.getExternalStorageDirectory().getName()
                    + "/" + fsitem.get(i)));
        }
    }
...
}

This piece of code checks wether root exists and can be written (.canWrite()), and does not exist (!.exists()). Both together is not possible, so nothing can happen.
