Secured folder in memory

Question

How is it possible to secure all the content downloaded by application? We need these files to be available only for this single app and can't be copied/viewed by any other app or by USB cable.

Referring to the documentation http://developer.android.com/guide/topics/data/data-storage.html#filesInternal

By default, files saved to the internal storage are private to your application and other applications cannot access them (nor can the user).

You can keep your files in internal memory. Try the following code

File myFolder = context.getDir("DirectoryName", Context.MODE_PRIVATE); //Create folder in internal memory;
File myFile = new File(myFolder, "fileName"); //Create file inside the folder.
FileOutputStream ouStreamt = new FileOutputStream(myFile);

Use the ouStreamt to write your content into the file. Hope this will help you

You can implement file encrytion\dercyption if it's really needed - link. But in most cases internal storage would be secure enough.
