在Android中使用当前用户的最佳方法

Question

When i get a user by json request in android i have a one class, example:

public class CurrentUser {
    public static String first_name = "";

    public static String getFirst_name() {
        return first_name;
    }

    public static void setFirst_name(String first_name) {
        CurrentUser.first_name = first_name;
    }
 }

and i class in mi activity class

my_text.settext(CurrentUser.getFirst_name());

But when app is in background i lose the data, existing any options without shared preferences?

Answer 1

There is more than one option but all leads to the same. You need to store this data manually. Using a saveInstanceState is an option, but it won't survice app closing. Other hand you can store it to the database using sqlite / realm or whatever you like.
