}
}
when I try setting the textviews as longtideu and latitude, i get a null pointer exception, not sure why. I get the first toast message so the location definitely isnt null. When i try setting my text in the try catch, Nothing works either.
I was expecting the app to return the longitude and latitude of the emulator
