In my Android application, I want to rename the file name at runtime. How can I do it?

This is my code:

String[] command = {" mv", "sun moon.jpg"," sun_moon,jpg"};
try
{
    Process process = Runtime.getRuntime().exec(command);
} 
catch (IOException e)
{
    Toast.makeText(this, ""+e, Toast.LENGTH_LONG).show();
}

I also used renameTo(File f) method but its also not working..
