What methods and technologies are used for organizing and storing data in Android applications?

Android applications use several main methods and technologies for organizing and storing data:

• SharedPreferences — for storing small key-value pairs, such as user settings.
• File system — for saving files, images, documents.
• SQLite — an embedded relational database for structured data.
• Room — an abstraction over SQLite that provides a convenient API and annotation support for database operations.
• Content Providers — for data sharing between applications.
• DataStore — a modern alternative to SharedPreferences that supports asynchronous and type-safe data operations.

The choice depends on the volume, data structure, and performance requirements. For complex structures and queries, it is better to use Room, while for simple settings, SharedPreferences or DataStore are suitable.
