Creating a directory in Internal memory (Root Folder)

Question

I am trying to create a Directory in the internal memory of the device...

I have done like this ...

File testDir = new File(Environment.getRootDirectory(),"Sample");
    testDir.mkdir();

But i cant see a folder created in the file explorer of DDMS when i run it in the emulator. I have also added

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

to the manifest file. Is anything else to be added... Is this the right way? If no plz suggest me the correct procedure.

Answer 1

You cannot write to the root of internal storage from an SDK application.
