I have a file manager app. I need to add following features to it.
1. Request for sd card access, if not granted already, first time when user wants to perform a write operation on sd card files(delete,rename, move, copy etc)
2. file rendering is too slow, it takes too much time to load files and populate view. Sometimes it gives ANR during swiping down to see more files. Fix this problem
Note: the project is being created on API 17 and I want to get it done using methods which does not require me to change API level of the project
