body: <p>How do I grant Read/Write Permissions to internal storage of my application to TextToSpeech/MediaPlayer?</p>
  
  <p>TextToSpeech.synthesizeToFile return -1 when I attempt to store file in internal storage of application ( for folder like /data/data/my.mycode.mydata/ )</p>
  
  <p>It works for SD card when I give permission for it. I think I get error ( return value -1 ) since TextToSpeech/MediaPlayer does not have permission for internal storage file creation.</p>
  
  <p>How do I provide it? probabally through manifest.xml?</p>
