Shared Preferences differences

1) What is the difference between

PreferenceManager.getDefaultSharedPreferences(context)

and

getSharedPreferences(name, mode)

2) And what does each of them do?

3) And how can I make a setting screen (Activity)?

1) You can have multiple SharedPreference files (so they are called SharedPreferences). The argument name of method getSharedPreferences(name, mode) specifies the the name of SharedPreference file to handle.

PreferenceManager.getDefaultSharedPreferences(context) returns the default SharedPreference file having default name and mode. Default name is based on your app's package name (as packagename_preferences.xml) and default mode is MODE_PRIVATE.

If you just want to use a single SharedPreferences file, PreferenceManager.getDefaultSharedPreferences(context) is concise to use.

2) With SharedPreferences you can save some key-value data.

3) Your last question: how to make a setting screen? is too wide topic to answer here. However, I suggest that using PreferenceActivity or PreferenceFragment you can manage a SharedPreferences without handling SharedPreferences directly.
