[android-beginners] Re: new'ing an Intent
btw, I have class called RootGameScreen in my workspace, namespace
button.setOnClickListener(new View.OnClickListener()
{
public void onClick(View v)
{
Intent startGameIntent = new Intent(this,
RootGameScreen.class);
In Java, this refers to the narrowest possible scope by default. So, in
your Intent constructor, this is the View.OnClickListener anonymous
inner class you are defining.
Change your code to:
Intent startGameIntent = new Intent(WelcomeScreen.this,
RootGameScreen.class);
and you may have better luck.

[android-beginners] Re: new'ing an Intent
The this you are passing into new Intent is an anonymous derived
class of View.OnClickListener not your derived Activity class
WelcomeScreen.
You will need to ask someone who knows more Java than I do how to get
at this in your outer class.

[android-beginners] Re: new'ing an Intent
Using WelcomeScreen.this instead of this should take care of the
problem Richard pointed out for this case.
