Shared Preferences
Shared Preferences is a lightweight data storage mechanism in Android development that allows apps to save simple key-value pairs persistently. It is used to store small amounts of primitive data types like booleans, floats, ints, longs, and strings. This tool is ideal for saving user preferences, settings, or simple app state information across app sessions.
Developers should use Shared Preferences when they need to persist small, simple data like user settings, login tokens, or app configuration without the overhead of a database. It is particularly useful for Android apps where quick, efficient storage of key-value pairs is required, such as saving theme preferences or remembering user login status. Avoid using it for large or complex data structures, as it is not designed for relational data or high-performance queries.
