我正在尝试从Intent获取Extras，但它会导致错误

我以这种方式开始活动

Intent facebookIntent = new Intent(this, FacebookSettings.class);
            startActivityForResult(facebookIntent, 15);

然后我在新活动中做了一些事情并最终以这种方式结束活动

    public void onClick(View v) {
            //FBnames and FBIds are not null String arrays
            Intent data = new Intent();
            data.putExtra(FB_NAMES, FBnames);
            data.putExtra(FB_IDS, FBIds);
            setResult(RESULT_OK, data);
            finish();
    }

我得到一个错误。在父活动中它甚至没有来到onActivityResult()。

您是否真的接受了发送给他们的课程的额外内容？像这样：

Bundle extras = getIntent().getExtras();

无法从Intent获得额外内容
