The first thing we must do is logically create our database For this, a Helper class is used in which we define the structure of our database the tables, data types, and primary keys are defined in this Helper made with Kotlin as the programming language: class ListSQLiteHelper(įactory: SQLiteDatabase.

After that your databases file will open. Device Monitor window will open, In File Explorer tab click data -> data -> your project name. Using SQLite database to store data locally Go to Tools -> DDMS or click the Device Monitor icon next to SDK Manager in Tool bar. SQLite is a lightweight and open database engine, whose main attraction is that we can easily and securely keep user or application data in a very small file and that differs from other systems such as MySQL in that it does not require the support of a server, it does not require port configuration support and so on and everything, but everything is stored in a single and simple file that is our database and it is open source therefore, you will see it in multiple applications that are not Android only with Android Studio or other similar IDEs.

In Android Studio go to View -> Tool Windows -> Device File Explorer, there find your package name (for example, ), then find folder databases -> right click -> Save As. In modern times we have seen how all applications today connect to an external API, server, essentially an external agent to bring data and present it. 2 Answers Sorted by: 0 You could put every question and answer in a file, line by line, things separated by a specific character. ![]() Databases are an essential tool to keep user data and the application in general safe, organized and accessible at all times this last point is essential and is to be able to access the saved data at all times.
