下面代码放在主线程中运行会引发ANR错误的选项是？
Toast.makeText(getApplicationContext(),"hello world",Toast.LENGTH_LONG).show();
mHandler.postDelayed(new Runnable() {<br>@Override<br>public void run() {<br>Toast.makeText(getApplicationContext(),"hello world",Toast.LENGTH_SHORT).show();<br>}<br>},5000);
LayoutInflater.from(context).inflate(R.layout.something_layout, null);
HttpURLConnection urlConn = (HttpURLConnection) new URL("https://www. iqiyi.com").openConnection();
