Text replacement - "<google>ADSDAQBOX_FLOW</google>" to "<htmlet>adsdaqbox_flow</htmlet>"
The user interface design for our activity is stored in a file named activity_android_sample.xml which, in turn, is located under app -> res -> layout in the project file hierarchy. This layout file includes the app bar (also known as an action bar) that appears across the top of the device screen (marked A in Figure 3-8) and the floating action button (the email button marked B). In addition to these items, the activity_android_sample.xml layout file contains a reference to a second file containing the content layout (marked C):
<googlehtmlet>ADSDAQBOX_FLOWadsdaqbox_flow</googlehtmlet>
