* and places it into outputDir.

Just like Android build tools generate fresh R class at every compilation. We can generate Java code which will provide method say getTldList() which will always return TLDs up-to-date at compilation time. But there is more efficient way – parse data before app compilation and use it ready-made at runtime.

OK, we’ve got a source, so how to embed that data in app? There are many ways to do it, for example we can just put downloaded text file in assets or res/raw directory and parse it at runtime. So where to get up-to-date TLD list from? Fortunately, there is machine-friendly source maintained by IANA: IANA - Root Zone Database. Furthermore, over the time some domains have been retired.ĪPI for managing TLDs in Android framework has been deprecated because it will become out-of-date very quickly. If you delete the directory, it will make the next build slower, because it needs to regenerate these files again, instead of reusing them. As you can see at ICANN TLD Report, there are over 1000 TLDs and new ones are being added once in a while. For example, the databinding library, ButterKnife, or Dagger 2 all generate java classes based on your annotations, which you can see in this directory. Note: You can create a singleton class by selecting File > New > Singleton or File > New > Java Class the latter technique offers more options. Currently am working in one process which uses Visual studio 2010. Android Studio generates a class called BuildConfig that contains constant values used when building a. With 3 ABIs and two versions of the application, 6 APKs needs to be generated (not counting the variants introduced by the different Build Types).

In this example, we will use list of Internet top-level domains. Android Studio creates a Java file with skeleton code that you can modify. For both the Java and Android plugin, the location of the Java source code and the Java. Data which is gathered from some external source and needs to be parsed to be usable inside an app. IntroductionĪssume that you have to embed some data in your Android application. Generate Java sources using buildSrc Gradle project and Codemodel.
