将结果ResultInfo {who = null，request = 64206，result = -1，data = Intent {（has extras）}}传递给活动失败

Question

我想要超出用户的照片和相册

我的代码是：

Session session;
private Session.StatusCallback statusCallback;

@Override
protected void onCreate(Bundle savedInstanceState) {
    session = new Session(getApplicationContext());
    statusCallback = new SessionStatusCallback();

    super.onCreate(savedInstanceState);


    ActionBar actionBar = getActionBar();
    actionBar.setDisplayHomeAsUpEnabled(true);

    if(!session.isOpened() && !session.isClosed()){
        session.openForRead(new Session.OpenRequest(this)
        .setPermissions(Arrays.asList("user_photos"))
        .setCallback(statusCallback));
    }else{
        Session.openActiveSession(FbGallery.this, true, statusCallback);
    }
}

private class SessionStatusCallback implements Session.StatusCallback {
    @Override
    public void call(final Session session, SessionState state, Exception exception) {
        if (session.isOpened() && session!=null) 
        {

            if (session.isOpened()) {
                Request.executeMeRequestAsync(session, new Request.GraphUserCallback() 
                {
                    //  callback after Graph API response with user object
                    @Override
                public void onCompleted(GraphUser user, Response response) {
                 if (user != null) {
                            gallery(session);
                 }
                    }
                    });
                }
        }
    }
}

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    Session.getActiveSession().onActivityResult(this, requestCode, resultCode, data);
}

我猜代码中的一切都很好，但为什么这个错误显示::

E/AndroidRuntime(18633): java.lang.RuntimeException: Failure delivering result ResultInfo{who=null, request=64206, result=-1, data=Intent { (has extras) }} to activity {jsoft.projects.photoprint_v1_1/jsoft.projects.photoprint_v1_1.FbGallery}: java.lang.NullPointerException
