Answer 1

You can try to call nextLine() until you reach the line that you want

Scanner scanner = new Scanner(new URL("http://www.somesite.us/1.txt").openStream())
while (scanner.hasNextLine()) {
            String test = scanner.nextLine();
             Toast.makeText(this, test, Toast.LENGTH_SHORT).show();
        }
