How to debug issues with SharedPreferences?

Debugging issues with SharedPreferences in Android can be challenging, but with the right approach, you can resolve them efficiently. This guide outlines common debugging techniques and provides a sample code snippet for reference.

    // Example of using SharedPreferences in Android
    SharedPreferences sharedPreferences = getSharedPreferences("MyPrefs", MODE_PRIVATE);
    SharedPreferences.Editor editor = sharedPreferences.edit();
    editor.putString("username", "example_user");
    editor.apply(); // Use apply() for non-blocking save or commit() for blocking save

    // Retrieving the value
    String username = sharedPreferences.getString("username", "default_user");
    Log.d("SharedPreferences", "Username: " + username);
    

Common issues you might face include:

• Values not being saved or retrieved correctly
• Default values being returned instead of expected values
• Changes not appearing immediately in the app

To resolve these issues, ensure you're using the correct keys when saving and retrieving data, and check if you're applying your changes properly with apply() or commit().
