Register in android a session like value shared by all activity

Question

How can I register data (like integer or poco objects) shared by all activity like the id of the user ? Have I to use a simple singleton or is there a special Android way ?

Note : I don't need to make that data persistant (no need of SharedPreferences or sqlite)

Thank you

You can create your own class that implements Application and specify this in your manifest file. In that case, every time you call getApplicationContext you will get a reference of your application that can hold any kind of information.

How to declare global variables in Android?

Sample code:

class MyApplication extends Application {
  public void setMethod() {
    //
  }
}

((MyApplication)getApplicationContext()).setMethod()

The android way is to create a custom Application for your project. Then in onCreate of that application you initialize whatever you need, and for example from an Activity do something like:

((MyApplication) getApplication()).getMyData()

If using roboguice you can use a @Singleton injection which basically does the boilerplate of a singleton for you - that's much nicer.
