To Save Object values into SharedPreferences, you can use GSON library.

To save objects follow these steps:

Add Gson library dependency in your Gradle (App Level):

dependencies {

    compile 'com.google.code.gson:gson:2.4'

}

Use the latest version of Gson library, currently the latest version is 2.4.

Suppose this is the class of which object you want to save:

public class ExampleClass {

    public String name;
    public int id;
    public ArrayList<String> list = new ArrayList<>();
    ...
    ...
    ...
}

To save object use this code:

ExampleClass myObject = new ExampleClass();

Gson gson = new Gson();
String json = gson.toJson(myObject);

SharedPreferences sharedPref = context.getSharedPreferences("pref1", 0);
SharedPreferences.Editor accessTokenEditor = sharedPref.edit();
accessTokenEditor.putString("my_object", json);
accessTokenEditor.commit();

To retrieve object use this code:

Gson gson = new Gson();
SharedPreferences sharedPref = con.getSharedPreferences("pref1",0);

ExampleClass myObject = gson.fromJson(sharedPref.getString("my_object", ""), ExampleClass.class);

And finally if you want to clear the saved object from SharedPreferences, use this code:

SharedPreferences sharedPref = con.getSharedPreferences("pref1", 0);
SharedPreferences.Editor accessTokenEditor = sharedPref.edit();
accessTokenEditor.clear();
accessTokenEditor.apply();
