我正在使用解析sdk 1.5.1版本在Samsung Note 2上崩溃，以下是我的Application类代码。

@Override
    public void onCreate()
    {       
        super.onCreate();

        try
        {


            Parse.enableLocalDatastore(this);
            // Live acc
            Parse.initialize(this, "XXXXXXXXXXXXXXXXXX", "XXXXXXXXXXXXXXXXXXXXXX");

            //Enable to receive push
            PushService.setDefaultPushCallback(this, RespondToPushActivity.class);

            Log.d("System out", "Parse ID----> "+ParseInstallation.getCurrentInstallation().getString("deviceToken"));
            Constants.PARSEID = ParseInstallation.getCurrentInstallation().getString("deviceToken");



            ParseInstallation.getCurrentInstallation().saveInBackground();
        }
        catch (Exception e)
        {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }    


    }

现在我得到了下面的堆栈跟踪：

如果有人能解决此问题，请与我们联系。 我也检查了这个，但那里没有回复。

尝试从手机中完全卸载应用并重新部署。我刚刚遇到了同样的问题，卸载（包括删除缓存和配置！）为我修复了它。

答案 1 :(得分：0)

您确定在Android Manifest中注册自定义Application类吗？

<application
        android:name=".MyApplication"
...>
.

</application>

答案 2 :(得分：0)

我有同样的问题。当它出现在您的stacktrace中时，在迭代LinkedList时遇到了java.util.ConcurrentModificationException：

at java.util.LinkedList$LinkIterator.next(LinkedList.java:124)

一种解决方案是保护synchronized block or method中的代码。

我选择的另一个解决方案是使用专门用于并发访问的集合。在我的情况下，我想要一个随机访问列表（如ArrayList），所以我使用了Android包 java.util.concurrent.CopyOnWriteArrayList中提供的java.util.concurrent。我没有为LinkedList找到任何并发访问集合，但是CopyOnWriteArrayList可能就足够了。它专门用于阅读很多列表并很少更新。

虽然我不能保证我找到了正确的解决方案（这是一个并发访问问题，所以这很难测试），我没有错误了，我认为我的问题已经解决了。
