Retrieve all stored entries from a particular SharedPreferences file

suggest change

The getAll() method retrieves all values from the preferences. We can use it, for instance, to log the current content of the SharedPreferences:

private static final String PREFS_FILE = "MyPrefs";

public static void logSharedPreferences(final Context context) {
    SharedPreferences sharedPreferences = context.getSharedPreferences(PREFS_FILE, Context.MODE_PRIVATE);
    Map<String, ?> allEntries = sharedPreferences.getAll();
    for (Map.Entry<String, ?> entry : allEntries.entrySet()) {
        final String key = entry.getKey();
        final Object value = entry.getValue();
        Log.d("map values", key + ": " + value);

The documentation warns you about modifying the Collection returned by getAll:

Note that you must not modify the collection returned by this method, or alter any of its contents. The consistency of your stored data is not guaranteed if you do.
