![]() Currently, it’s recommended to use the Room Persistence Library instead, which will provide an abstraction layer for accessing the data in your app’s SQLite databases. It’s capable of creating in-memory databases, which are very fast to work with.Īndroid provides the APIs necessary to create and interact with SQLite databases in the package.Īlthough these APIs are powerful and familiar to many developers, they are low-level and do require some time and effort to use.It allows a single database connection to access multiple database files simultaneously.This means you can store a value in any column, regardless of the data type. Some distinctive features of SQLite include: SQLite is a library that provides a DBMS, based on SQL. The default database management system (DBMS) that Android uses is called SQLite. ![]() However, sometimes an app needs to store larger amounts of data in a more structured manner, which usually requires a database. Using Files and Shared Preferences are two excellent ways for an app to store small bits of data.

The user's profile activity can use the first 4 tables and that 1 table that shows something the user can be, a second activity that shows the other 5 tables, and the last 3 tables can be accessed from the conversation activity. After searching for ways to do that, I found that it is best to use WorkManager to do the necessary threading (I have never done threading so any help or tutorial is appreciated).Ĥ of them are directly related to the user (the user's personal information), 5 are linked to some activity the user performed, 1 can be related to something else the user can be (it's not mandatory), and the last 3 are linked to the conversation that the user has. The android studio tutorial on SQLite recommends that I set up a background thread to call getWritableDatabase()) or getReadableDatabase()). In my app all the tables (13 in total) are in the same database. ![]() Material Design Icons Weekly Threads Calendar For news and questions about these topics try using other subs likeĪndroid Job Interview Questions and Answers This sub-reddit isn't about phones' and apps' general functionality, support, or system software development (ROMs).
