Intro to developing for Android

Very good intro to developing for Android:

Had some trouble with the app not loading into the Android virtual machine (from eclipse)
Try this:

Open windows task manager.  Kill the adb process.  In Eclipse, try running it again, should be

able to select the currently running virtual machine to load your application into.

This is not bad either:
