The easiest way to do this would be to pass the id to the activity in the Intent you're using to start the activity:
Intent intent = new Intent(getBaseContext(), SignoutActivity.class); intent.putExtra("ID", id); startActivity(intent);
Access that intent on next activity:
String sessionId = getIntent().getStringExtra("ID");

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 next activity:
String sessionId = getIntent().getStringExtra("EXTRA_SESSION_ID");
The [docs][1] for Intents has more information (look at the section titled "Extras").
