evaluate that markup for errors or warning highlights, and provide the necessary pop-up helper
dialogs that explain what might be wrong.

To apply a concept which I have been trying to “drive home” thus far during the book, Eclipse’s
XML markup evaluation algorithm could be considered to be implemented in a “static” fashion, as
it requires “submission” to Eclipse by using the “Save” function. In contrast, the Eclipse Java code
evaluation algorithm could be said to be implemented in a “dynamic” fashion, as it does not require
submission, but rather occurs in real time, evaluated by Eclipse’s Java logic processing algorithm
while the Eclipse software is running (performing other operations), and while you are typing in your
Java programming logic structures. Before we can continue on, you will need to make an application
Minimum SDK Version configuration edit in the child tag in your HelloUniverse
application’s AndroidManifest.xml file.

Upgrading Your HelloUniverse App to Android 4.0

Let’s open up your AndroidManifest.xml file in the Eclipse central editing pane, by right-clicking on
the file, and using the Open menu option, or left-click on the AndroidManifest.xml file, and use the
F3 function key. Change the android:minSdkVersion parameter from its current value of “ 8 ” to a
value of “ 14 ,” as is shown in Figure 8-2.
