Building Android Apps: Persisting Data Locally

Skillsoft issued completion badges are earned based on viewing the percentage required or receiving a passing score when assessment is required. Various methods can be used for persisting data locally in an Android device. App-specific files and preferences offer a lightweight and straightforward approach for storing small amounts of data, such as user settings and preferences. SQLite databases and the Room API provide a robust and efficient solution for more structured and organized data. This enables data persistence for larger datasets with powerful querying capabilities and data manipulation operations. In this course, you will learn the essential aspects of data and file storage on Android. Through hands-on practice, you will build a simple app that stores recipes locally using app-specific files. Next, you will work with storing and retrieving shared preferences, a simple yet effective method to store key-value pairs in Android. Using shared preferences, you will build features to track and utilize recently searched items and prefill forms in your app. Finally, you learn to store app details in a local SQLite database, retrieve and modify data using the SQLite API, and later connect to SQLite using the Room API.
