NewRelic

Question

我一直在使用NewRelic sdk来跟踪我的应用程序上的网络请求，现在我收到了一些NullPointerException，例如下面的那个;

java.lang.NullPointerException

   at android.os.HandlerThread.run(HandlerThread.java:60)

每当我尝试向一个特定网址发出http请求时。我怎么能抓住这个例外？

以下是发出http请求的代码

 private void checkForApiChanges() {
    String version = null;

    try {
        Document doc = Jsoup.connect(CHECK_URL).get();
        Elements v = doc.select("p.version");

        for (Element el : v) {
            version = el.text();
        }

    } catch (IOException | OutOfMemoryError | ExceptionInInitializerError e) {
        e.printStackTrace();
    }
}
