The android.app Activity getPreferences method is used to get a SharedPreferences object that can be used to retrieve or update preference values associated with an activity. This method takes a mode parameter which determines the file the preferences will be stored in. The package library for this method is android.content.SharedPreferences.
1. To get a SharedPreferences object for a specific activity:
This will retrieve the SharedPreferences object associated with the current activity and store it in the prefs variable. The MODE_PRIVATE parameter specifies that the preferences will be stored in a file only accessible by the calling application.
2. To retrieve a value from the preferences:
int value = prefs.getInt("my_key", 0);
This will retrieve the integer value associated with "my_key" from the preferences. If no value is found, it will return 0.
This code creates an editor object to modify the preferences and sets the value of "enabled" to true. The commit method is called to save the changes to the preferences file.
Overall, the android.app Activity getPreferences method is a convenient way to access and modify preferences for an activity. It allows developers to easily store and retrieve data between application launches.
