How to create private folder in sdcard
android, sqlite
Solution
According to this guide, you can save files directly on the device's internal storage. By default, files saved to the internal storage are private to your application and other applications cannot access them (nor can the user). When the user uninstalls your application, these files are removed. For example:
String FILENAME = "hello_file";
String string = "hello world!";
FileOutputStream fos = openFileOutput(FILENAME, Context.MODE_PRIVATE);
fos.write(string.getBytes());
fos.close();
MODE_PRIVATE will create the file (or replace a file of the same name) and make it private to your application. Other modes available are: MODE_APPEND, MODE_WORLD_READABLE, and MODE_WORLD_WRITEABLE.
Problem
My application is used for security purpose. so, from my application user captures photos that all photos are stored in a folder that folder should not access from any other application and should not give access when devices connect to computer system. If user wants to view these images he should access only from my application.
