Question

            if (folder.listFiles() != null) {
                for (File file : folder.listFiles()) {
                    if (file.isFile()) {
                        Log.v("vvv", "file with name " + folder.getName() + " in path " + folder.getAbsolutePath());
                    } 
                    }
                }

This prints something like this

   /vvv     ( 3940): Folder with name .thumbnails in path /sdcard/DCIM/.thumbnails
V/vvv     ( 3940): file with name .thumbnails in path /sdcard/DCIM/.thumbnails
V/vvv     ( 3940): file with name .thumbnails in path /sdcard/DCIM/.thumbnails
V/vvv     ( 3940): file with name .thumbnails in path /sdcard/DCIM/.thumbnails
V/vvv     ( 3940): file with name .thumbnails in path /sdcard/DCIM/.thumbnails
V/vvv     ( 3940): file with name .thumbnails in path /sdcard/DCIM/.thumbnails
V/vvv     ( 3940): file with name .thumbnails in path /sdcard/DCIM/.thumbnails
V/vvv     ( 3940): file with name .thumbnails in path /sdcard/DCIM/.thumbnails
V/vvv     ( 3940): file with name .thumbnails in path /sdcard/DCIM/.thumbnails
V/vvv     ( 3940): Folder with name Camera in path /sdcard/DCIM/Camera
V/vvv     ( 3940): file with name Camera in path /sdcard/DCIM/Camera
V/vvv     ( 3940): file with name Camera in path /sdcard/DCIM/Camera
V/vvv     ( 3940): file with name Camera in path /sdcard/DCIM/Camera
V/vvv     ( 3940): file with name Camera in path /sdcard/DCIM/Camera
V/vvv     ( 3940): file with name Camera in path /sdcard/DCIM/Camera
V/vvv     ( 3940): file with name Camera in path /sdcard/DCIM/Camera
V/vvv     ( 3940): file with name Camera in path /sdcard/DCIM/Camera
V/vvv     ( 3940): file with name Camera in path /sdcard/DCIM/Camera

for (File file : folder.listFiles()) {
    if (file.isFile()) {
       Log.v("vvv", "file with name " + folder.getName() + " in path " + folder.getAbsolutePath());
    } else {
                                        ^^^^^^

You probably meant file.getName().
