How to rename a file on sdcard with Android application?

Question

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\"

I tried adding permissions. Even though it did not work, adding File1.setWritable(true); enabled me to rename the file.

Below is my code snippet:

if(from.setWritable(true))
    Log.d("InsertFragmentTwo ", "FileName==> Is Writable");
File two = new File(sdcard,""+imageCount+"."+s.substring((s.lastIndexOf(".")+1)));
if (from.renameTo(two)) {
    Log.d("InsertFragmentTwo ", "New FileName==> " + temp);
    imageCount++;
    retrofitImageUpload(temp);
} else
    Log.d("InsertFragmentTwo ", "File Renaming Failed");
