Please help, I can find the distance of one beacon but I can't populate a listview with other beacons in the region. I've tested the listview by just using a string array, populates fine. Everything else works but I'm at a total loss for this last part, close to the edge here...
Here's my code for the main activity`import android.app.Activity;

My layout code is here, as I said the UI mostly works already but maybe I've missed something with the listview...
