Before Android 7.0, i was able to get list of files under "/" directory, but on Andorid 7.0 version i am getting null when i try t get list of files from "/" directory.
Below is my code:
File root = new File("/");
File[] files = root.listFiles();
From android 7.0 they have applied more restrictions. Now you need to get access for individual directories.
