title: Save file internal storage android works just with the terminal
body: <p>I am trying to save a file into internal storage.
  I have seen these link:
  <a href="https://stackoverflow.com/questions/14376807/how-to-read-write-string-from-a-file-in-android">How To Read/Write String From A File In Android</a>
  <a href="https://stackoverflow.com/questions/13161470/saving-file-in-internal-storage-android">saving file in internal storage android</a></p>
  
  <p>They both work but just when i run my app with the terminal! i run the DDMS and i see the file saved.
  But when i try with the galaxy nexus or lg optimus 2 the file is not saved.</p>
  
  <p>thanks</p>
