Run the app to ensure it builds and functions correctly.ġ.1.Change the package name in your adle file.Rename the package using Refactor > Rename.Refer to the Appendix for information on copying a project. Load a copy of the app into Android Studio.As long as the app uses a SQLite database, you can use these instructions to extend it. ![]() You can use your own app, or download the base app. In a production environment, building on existing application code is a common developer task to add features or fix problems. ![]() In order to save you some work, this practical will build on an app you have already built. For example, entering "Android" will return all entries that contain the substring "Android". You will make a copy of the finished WordListSQLInteractive app (or WordListSqlStarterCode if you didn't rename it from a previous practical), call it WordListSQLInteractiveWithSearch, and add an activity that lets users search for partial and full words in the database.
