Build a simple app on Android

[Alex Tweedly]

I'm trying to build a VERY simple app, and try it on Android.

It is very simple - one Button (B_, and one field (F); click on the 
button, it downloads a URL and puts the content into the field.

The script for the button consists of :

on mouseUp pMouseButton
   localt
putemptyintofld"F"
   put"----"&CRafterfld"F"
   putURL("https://www.kilmelford.com/puzzles/sudoku.txt") intot
   puttheresult& "::"& it &CRafterfld"F"
   putt afterfld"F"
end mouseUp

This gives me

tsneterr(6) could not resolve host.

Is there something on Android that I need to do to give permissions to 
the app ?

How?

What ?

Thanks

Alex
