您可以在Session.StatusCallback之后实现活动意图会话facebook打开

例如：

You can implement the activity intent at the Session.StatusCallback, after the session facebook is opened
For example:

private Session.StatusCallback statusCallback = new Session.StatusCallback() {
		@Override
		public void call(Session session, SessionState state,
				Exception exception) {
			if (state.isOpened()) {
				Log.d(TAG, "Facebook session opened.");
				if (session.isOpened()) {
					Log.d(TAG, session.getAccessToken());					
					Intent intent = new Intent(this,
							MainActivity.class);
					startActivity(intent);
				}
			} else if (state.isClosed()) {
				Log.d(TAG, "Facebook session closed.");
			}
		}
	};
