Why am I getting an empty screen in Eclipse when emulating a simple Hello World program for Android?

Question

I'm following this tutorial: http://developer.android.com/training/basics/firstapp/running-app.html#Emulator

In it there is a simple code for a layout with a Text parser and a button. When I input the code in my Eclipse and "Run" the program I arrive at an empty Android phone simulation. The phone diplays "Android" across the screen and my program does not run. Please instruct me on where I am making a mistake. My code is equal to the code in the tutorial, by the way.

It's booting. You just have to wait for the emulator to start. It's just like real Android devices: it takes a while to boot. When it shows the desktop, it will launch your application.

On slow machines it might take a while (and I mean a good while). May I suggest a faster/stronger machine, or even better, a real Android device, for testing.

For better performance, do not close emulator window, this way it won't have to boot each time.
