AdapterTransitionSample successfully build

Following the leads as given in the following link (but I did not use Eclipse nor Android Studio, just command line Gradle 1.10 to compile Android SDK samples):

http://stackoverflow.com/questions/13865748/android-eclipse-error-executing-aapt-return-code-139

I have to search through the entire application for "android.*string" pattern and identified the following three strings as missing, and so adding the following three lines to "src/main/res/values/strings.xml"  (this is from Android SDK sample, android-sdk-linux/samples/android-19/ui/AdapterTransition/AdapterTransitionSample):

    <string name="show_as_grid">Show as grid</string>
    <string name="show_as_list">Show as list</string>
    <string name="item_clicked">item clicked</string>

And now "gradle build" build fine:
