How do I pass data between Activities in Android application?

I have a scenario where, after logging in through a login page, there will be a sign-out button on each activity.

On clicking sign-out, I will be passing the session id of the signed in user to sign-out. Can anyone guide me on how to keep session id available to all activities?

Any alternative to this case

Solution

  • The easiest way to do this would be to pass the session id to the signout activity in the Intent you're using to start the activity:

    Intent intent = new Intent(getBaseContext(), SignoutActivity.class);
intent.putExtra("EXTRA_SESSION_ID", sessionId);
startActivity(intent);

    Access that intent on the next activity:

    String sessionId = getIntent().getStringExtra("EXTRA_SESSION_ID");

    The docs for Intents has more information (look at the section titled "Extras").
