I need to pass object user to another activity. I know I should use Parcelable, but I can't edit User class, because it is used from maven repository.

Is it here any other way how can I pass user object? Or how to locally edit class from maven repository?

  • You can probably use a event bus with sticky event – rahul.ramanujam Jun 10 '15 at 23:31
  • I think you should read all users in an arraylist, Create a variable of user type, get/find/match the user object that you want to pass to another activity (best with for loop) with the items in arraylist , once got/found/matched the user - assign the value to the variable that is created above, and then you can call any method and pass the variable as a parameter to another activity. – VD007 Jun 10 '15 at 23:48

You can use the Application class for this purposes. what you need is:

  1. create a class which derives from Application.
  2. declare the class in the AndroidManifest.xml (see here)
  3. create a object variable of type User in it (also getter and setter).

  4. assign the user object in first activit through:

    MyApplication app = (MyApplication) getApplication(); app.setUser(user);

  5. retrieve the object in other activity through:

    MyApplication app = (MyApplication) getApplication(); User user = app.getUser();

BUT: take care, after you restart you app (go in background and open it again), a new Application object will be created, where the User is null, take care of that then.

This problem can be read here.

Hope this helps.

You can serialize the object into some kind of string representation. The easiest way to do this is to convert the object into a JSON string, pass the string to the other activity via intent and convert the string back into the original object.

What I am doing is just converting the object into Json and then sending as a String using Intent. Then you can't catch it and parse Json.

P.S. Using google's Gson class making this very easy. https://code.google.com/p/google-gson/
