You can use SharedPreferences.

This is an example shown for Facebook. You can implement the same way for for LinkedIn.

When the user has logged in:

Editor editor = context.getSharedPreferences("facebook-session", 
                                             Context.MODE_PRIVATE).edit();
editor.putString("access_token", session.getAccessToken());
editor.putLong("expires_in", session.getAccessExpires());

When you app starts, in onCreate, restore the session if it exists:

SharedPreferences savedSession = context.getSharedPreferences
                                 ("facebook-session",Context.MODE_PRIVATE);
session.setAccessToken(savedSession.getString("access_token", null));
session.setAccessExpires(savedSession.getLong("expires_in", 0));
