I'm doing the "first app" lessons on Android Developers, but the app will not run

http://developer.android.com/training/basics/firstapp/running-app.html

That's the page I'm on. So far it's been pretty simple, because besides naming the app "My First App", it hasn't had me change a thing.

However, when I click Run or even try to click Run As, Eclipse tells me that there's a error in the project,though the red X is only on the project name, and is nowhere else to be found.

Normally when I have done Java programming, the code where the error was could be found easily, but I can't in here. Furthermore, I don't see why there is an error, seeing as the code in here seems to be a template "Hello World!" app, that I have not altered once.

I've tried starting over again several times, but each time it always tells me that the app can't launch because my "project contains errors".

Right click on the project Properties -> Android and make sure appropriate target is set.

I had a similar experience. Cleaning the project did it all the good in the world

I had this problem earlier and I think it's just a loading issue. Try restarting Eclipse, it worked for me.
