What I am concerned now, is to find a proper way to access the SDcard contents. This path which is working for me (/storage/0000-0000/LMS/) does not seem to be the standard method of calling any sd card (I assume). I tried the code piece below (file:///mnt/sdcard/LMS/index.html) but somehow it opens the LMS folder present at the root of the phone memory (not the sdcard one - I checked very carefully by changing names).
What is the standard way/path of calling any content on the sdcard?
