You can use PreferenceFragment like any standard Java library. Please include the the jar files in your classpath. You can also use any IDE and you can run and debug the PreferenceFragment component as you would do with any other Java program. Best practice is to use a build tool that supports dependency management such as Maven or Gradle. For Maven installation, please refer maven.apache.org. For Gradle installation, please refer gradle.org .
