Expand the node for the database that we need to inspect. The databases in the currently running app appear in the Databases pane.Select the running app process from the dropdown menu.Select View > Tool Windows > Database Inspector from the menu bar.Run the app on an emulator or connected device running API level 26 or higher.To open a database in the Database Inspector, do the following: The Database Inspector only works with the SQLite library included in the Android operating system on API level 26 and higher. The Database Inspector works with plain SQLite and with libraries built on top of SQLite, such as Room. This is especially useful for database debugging. The database inspector is available in Android Studio 4.1 and higher. Database Inspector in Android Studioĭatabase Inspector allows us to inspect, query, and modify our app's databases while our app is running. ContentValues object will be passed to SQLiteDataBase objects insert( ) and update( ) functions. ContentValues is a name-value pair, used to insert or update values into database tables. We can use a ContentValues object, which stores keys and values. The SQLiteOpenHelper class has different in-built methods for inserting, updating, reading, and deleting records.Īfter the database has been created we need to create and update fields. We can see that the DatabaseHelper class is extended from SQLiteOpenHelper. The below statement instantiates an object of the SQLiteOpenHelper class and calls its constructor. These functions are available in the super SQLiteOpenHelper class. It will be called whenever there is a first call to getReadableDatabase( ) or getWritableDatabase( ) function. It is called only once throughout the entire application lifecycle. The onCreate( ) is called when the database is created for the first time. These classes take care of opening the database if it exists, creating it if it does not, and upgrading it as necessary. In this class, we will implement two overridden methods onCreate( ) and onUpgrade( ). We need to create a subclass extending from SQLiteOpenHelper class for database manipulations. The helper class manages the creation of the database, handling database manipulations, and also the version management. It is a helper class to manage SQLite database creation and version management. SQLiteOpenHelper is an in-built class of package. The package consists of all the APIs to perform CRUD operations from our android application. It carries lightweight data and does not require any administration or setup procedure of the database. SQLite is built into all mobile phones and most computers and comes bundled inside. A complete SQLite database with many tables, triggers, indices, and views is contained in a single disk file. SQLite does not run on a database server, but stores all its data in simple files. Android includes a SQLite library in its standard library that implements a serverless, zero-configuration, and transactional SQL database engine. SQLite is an open-source relational database, similar to MySQL.
