I have tried all day to capture a trackball event in a View. Basically
I want to use the trackball to move a Sprite in a 2D game left and
right. The onTouchEvent works perfectly well in the View to move the
Sprite with my finger but it would be nicer and cleaner to use the
trackball.

The best place to go to install the ADT plugin is

Go down to Eclipse 3.4 (Ganyamede) section and the site you want to
add on is:

I don't have good success using the https:... site so use http
setRequestedOrientation (ActivityInfo.SCREEN_ORIENTATION_PORTRAIT); or
whatever orientation you want.

How can I change the Android view from horizontal to Vertical by
force? Can the view switch dynamicly?
You can compute a normal to each face of the cube to determine
direction. Here is a URL to the basics of the mathematics (http://
www.geocities.com/SiliconValley/2151/math3d.html). Look for code on
the internet that computes normals in 3D. If your mathematics isn't
good, this will be a problem.
Like all of us, you need to just start coding to get a feel for the
various layouts and how they work. Without knowing what your quiz
questions are going to look like, I've found the most flexible
features for quiz like apps is using a table in a relative layout. If
your quiz is multiple choice,
Does anyone know how to convert the accelerometer readings from g's to
degrees? For example, if I want to use the x-axis readings and measure
the tilt of the phone, flat would be 0g = 0 degrees and a 90 degree
tilt to the right would be 1g (9.80665 m/sec^2). I can't come up with
a formula for say
I develop in Windows, Linux (SUSE 11.0), Parallels, and VirtualBox.
The worst experience I have had is with VirtualBox. It seemed to crash
on me quite often and I had trouble synching up my G1 with the
VirtualBox environment after installing the USB driver. My guess is
that I'm doing something
