This error is caused because it can´t find the string loading from the resources, check if it´s correctly spelled if it´s try to re-build the gradle and the sync the project.

just press alt + enter in loading and select Create string value resource "loading" and then write the Resource Value of the string, just put in Resource Value: loading

also inside setMessage you can work with a string like this

mProgressDialog.setMessage("Loading...");

but is a good practice to use Strings than hardcodeding strings.

You can follow this images

First alt + enter into loading

Then just write Loading... inside Resource Value

Then you can go to your Strings.xml that is inside res - values and see that yoru String is there
