java - 将致命碰撞变成非致命碰撞分析报告

Question

有问题的代码:

final GenericAsyncTask task = new GenericAsyncTask();

        task.background = new Runnable() {
            public void run() {
                HttpClient httpclient = new DefaultHttpClient();
                HttpPost httppost = new HttpPost(GCMIntentService.this.host);
                String addremove = "add";
                if(register == false) addremove = "remove";

                try {
                    // Add your data
                    List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(4);
                    nameValuePairs.add(new BasicNameValuePair("cmd", addremove));
                    nameValuePairs.add(new BasicNameValuePair("subscription_key", SUBSCRIPTION_KEY)); // unique per app
                    nameValuePairs.add(new BasicNameValuePair("token", str));
                    nameValuePairs.add(new BasicNameValuePair("os_family", "android"));
                    if(addremove.equals("remove")) nameValuePairs.add(new BasicNameValuePair("hard", "" + hard));
                    UrlEncodedFormEntity entity = new UrlEncodedFormEntity(nameValuePairs);
                    httppost.setEntity(entity);
                    Log.i(LCHApplication.TAG, "Name Value Pairs: " + nameValuePairs.toString());

                    // Execute HTTP Post Request
                    HttpResponse response = httpclient.execute(httppost);
                    task.result = EntityUtils.toString(response.getEntity());
                } catch (IOException e) {
                    e.printStackTrace();
                }
            }
        };

        task.callback = new Runnable() {
            public void run() {
                Log.i(LCHApplication.TAG, "registration response: " + task.result.toString());
            }
        };

        task.execute();

大多数情况下效果很好。然而，有时 task.result.toString(); 有时是 NULL，这会引发 java.lang.NullPointerException。我想保留这次崩溃，因为我希望它在 crashlytics 中报告，这样我就可以看到它影响了多少人。如果我使用 try/catch，我可以抛出什么来确保它不是致命的崩溃？这样它仍会向 crashlytics 报告，但不会终止该应用。

你不必抛出任何捕获的异常，你可以像这样很容易地记录它们:

try {
  myMethodThatThrows();
} catch (Exception e) {
  Crashlytics.logException(e);
  // handle your exception here! 
}
