How to copy files in Android Storage?

Question

  <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>

I am trying to copy .jpg file to and from in Storage folders.

  try {
        Process c = Runtime.getRuntime().exec("dd if="+path+ 
        "of="+Environment.getExternalStorageDirectory()+"/1.jpg");
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }

path contains the exact image location in storage ! But it doesn't work. It can't copy the image to another folder of storage. Please kindly help me to solve this in every possible way! Thank you.

It happens to me sometimes and I use

Environment.getExternalStorageDirectory().getPath()

Have you tried that?

        Runtime.getRuntime().exec(cmd+"\n");

    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
