Data Persistence in Android: SharedPreferences and SQLite

In Android, you can store data locally using either SharedPreferences or SQLite databases.

Using SharedPreferences

    SharedPreferences sharedPreferences = getSharedPreferences("myPrefs", Context.MODE_PRIVATE);
    SharedPreferences.Editor editor = sharedPreferences.edit();
    editor.putString("username", "JohnDoe");
    editor.apply();
  

Using SQLite

    SQLiteDatabase db = openOrCreateDatabase("myDatabase", MODE_PRIVATE, null);
    db.execSQL("CREATE TABLE IF NOT EXISTS users (id INTEGER PRIMARY KEY, name TEXT);");
    db.execSQL("INSERT INTO users (name) VALUES ('John Doe');");
