Protected folder in memory

Question

How can I protect all content downloaded by the application? These files should be accessible only for this separate application and cannot be copied / viewed by any other application or USB cable.

Answer 1

You can store 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 ouStreamt to write your content to a file. Hope this helps you.
