I am trying to add Context.MODE_WORLD_READABLE permission to FileOutputStream(file,append) which is only possible in context.openFileOutput(name,Context.MODE_WORLD_READABLE) but i dont need openFileOutput since I am not able to make sub directories and also i need append mode true.

What can i do???

Thanks In Advance

Instead of using openFileOutput / openFileInput You can access file /directories from internal storage of application sandbox by path like /data/data/(package name) and on this path you can do anything will able to crate directory or files. Also in this scenario you will able to use files writable modes.

  • File file=new File("/data/data/com.example/newfile.txt"); try { file.createNewFile(); FileOutputStream out=new FileOutputStream(file, true); //true will be open file in appended mode out.write("My data".getBytes()); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } – Swapnil Deshmukh Sep 21 '12 at 07:21
  • FileInputStream in=new FileInputStream(file); For file reading input stream is used and input stram is only supported with reading thats y it has no mode. You can use writable/append permission while writing file. It will not supported for reading. – Swapnil Deshmukh Sep 21 '12 at 09:32

Short answer: Use FileOutputStream as usual, then close it, then call File.setReadable.

Take a look here for more details: java set file permissions to 777 while creating a file object
