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. ProguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'Ĭompile fileTree(dir: 'libs', include: )Ĭompile ':appcompat-v7:21.0.3'Īs previously outlined, the project is going to consist of two build types (release and debug) together with two flavors (phone and tablet). Once loaded into the editor, the build file should resemble the following listing: apply plugin: ''ĪpplicationId "" The project will then be further extended to provide an example of how each flavor might make use of different source code bases in order to provide differing application behavior. Initially the two flavors will be configured such that they differ only visually in terms of the resources that are used for each target such as layouts and string values. The build flavor, on the other hand, typically defines what is built (such as which resource and source code files are to be included in the build) for each variant of the module. In general, a build type defines how a module is built (for example whether or not ProGuard is run, how the resulting application package is signed and whether debug symbols are to be included). This raises the question as to the difference between a build type and a build flavor. The end result, therefore, will be four build variant options available for selection within Android Studio: The build environment will be configured such that each flavor can be built using either a release or debug build type. The goal of this chapter is to use the build variants feature of Android Studio to create a project which can be built in two flavors designed to target phone and tablet devices respectively.
