[android-beginners] Re: Convert framebuffer in video
We have no plans to support this function in the framework. It's a significant security risk (allowing an application to snoop the frame buffer), and on some hardware, the app processor may not even have access to the final framebuffer.

[android-beginners] Re: How to show a dialog on top of another dialog in an activity
Hihi,
you found about how to use if the user entered information in some

But I want to correct method you have used.
you should method show().

I have read the other posts that say that the problem is a mix of

XP. I have:
0.8.0 Android
3.4.2 Eclipse
6.0.120.4 JRE
One post said that I needed 1.0 of the Android ADT. If so, where is
that? When I look at the google site, it looks like 0.8 is the most

That's an interesting thought and I commend your ambition. Android is a platform rather than a language, an operating system for mobile phones. There are plenty of resources online for you to learn more. If you develop applications, this list is for said developers, then you will program in Java.

Android is the operating system for t mobile G1 phones and apparently if you want to create a G1 app, you have to use the android sdk with eclipse.

An error message would be helpful Otherwise it's hard to help you,

Maybe you haven't set the ID correctly, using a wrong ID (which
doesn't even exist in the XML Layout file) or you're using
setContentView/setView after you have using findViewById. This could
throw up a NullPointer Exception when you try to access (because
findViewById returns 0 if no layout has been set or the View with this
ID was not found).

You must call setContentView() first.
You aren't telling Android what layout to display until you call
setContentView(). Hence, until that time, findViewById() is guaranteed
not to work, because there are no views to find.
