In android, Shared Preferences are used to save and retrieve the primitive data types (integer, float, boolean, string, long) data in the form of key-value pairs from a file within an apps file structure.There are certain situations when you want to have some kind of Settings in your application apart from the Android default Settings. Generally, the Shared Preferences object will point to a file that contains key-value pairs and provides a simple read and write methods to save and retrieve the key-value pairs from a file. The Shared Preferences file is managed by an android framework and it can be accessed anywhere within the app to read or write data into the file, but it’s not possible to access the file from any other app so it’s secured. The Shared Preferences are useful to store the small collection of key-values such as user’s login information, app preferences related to users, etc. to maintain the state of the app, next time when they login again to the app. In android, we can save the preferences data either in single or multiple files based on our requirements. In case if we use a single file to save the preferences, then we need to use getPreferences() method to get the values from Shared Preferences file and for multiple files, we need to call a getSharedPreferences() method and pass a file name as a parameter. This method is for activity level preferences and each activity will have its own preference file and by default, this method retrieves a default shared preference file that belongs to the activity. This method is useful to get the values from multiple shared preference files by passing the name as a parameter to identify the file.
We can call this from any Context in our app. The following are the different ways to initialize the Shared Preferences in our application.
