Changes

As previously outlined, the project is going to consist of two build types (release and debug) together with two flavors (phone and tablet). As is evident from the build file, the release build type is already declared in the file so this does not need to be added. In practice, Gradle is also using sensible default settings for the debug build so this type also does not need to be added to the file. All this leaves is the requirement to declare the two build flavors as follows:

<pre>

apply plugin: 'com.android.application'

Within the Project tool window, right-click on the BuildExample -> app -> src directory and select the New -> Directory menu option and create a new directory named phone/res/layout. Right-click once again on the src directory, this time adding a new directory named phone/res/values.

Finally, find the BuildExampleActivity class which is located in the src -> main -> java -> com.ebookfrenzy.buildexample folder, right-click on it and select the Copy menu option. Right-click on the new package added to the phone variant and select the Paste menu option to copy the Activity source file into the package. In the resulting Copy Class dialog click on the OK button to accept the default settings.

The phone variant now has its own version of the activity class. Using the Build Variants tool window, change the build variant to tabletDebug and repeat the above steps to add instances of the package and Activity class file to the tablet flavor of the build.
