1. How do I get all folders with photo.
2. How do I get media from mediastore efficiently

Answer 1

Intially , album name will be empty

String albumName = albumTitle;

So if you aint enter the album name, the path would be like

String ExternalStorageDirectory = Environment.getExternalStorageDirectory().getAbsolutePath()
            + "/My_Albums/";

it will go the parent path ,get all the albums under that node and display the number of images under it. when once you provide albumname,it will get all images inside it and displays.In this scenario you need to loop inside album to cover each and every album under it and get the image paths from them.
