Before taking the value make sure you have added items in the global listaindex ,
After clicking reload button click on the global list and use do it. You will come to know the reason for your problem
Try to store the html file in the assets and open it from there like this
http://localhost/index.html
Also remove all those permissions...
For text files not owned by your app (here that html file from shared storage /Download) you need SAF to access it, see also Some basics on Android storage system
