Nice and helpful tutorial

I am very new to Android and Java.. so i have one question here.

why have you defined the ‘radioListener’ and TextView at the class level as globals. what happens if we define inside the onCreate method

Very clear and understandable. Good for android beginners. Thanks.

More advanced tutorials like using google maps and cameras etc will be more helpful, if possible.

And one small question… Developing android application for mobile devices is same as developing on any other device like a tablet ? or are there any differences in the practices we follow.

I’m using API version 8 (2.2) and I’m unable to cast from a View to a RadioButton in this line of code:

RadioButton rb = (RadioButton)v;

Hi, great tutorials however I have a couple of questions:-
1) Can I download the turorials to watch offline ?
2) In tutorial 5 you created “tvPick = (TextView)findViewById(R.id.current_pick);” 4 times but only one was needed.
3) Why create a new button and set a listener to if with:
RadioButton rb_red = (RadioButton)findViewById(R.id.radio_red);
rb_red.setOnClickListener(radioListener);
Why not like this:
findViewById(R.id.radio_red).setOnClickListener(radioListener);

Thanks John

i think this was another good tutorial, and i think it’s good how you seem to show different ways of doing things as the lessons go on. but, i’m a little confused about how we seem to be casting the View v as a RadioButton. maybe i missed the part where this is explained, but i don’t understand why we are doing this.
