我的Android应用程序不断显示警报“不幸的是应用程序已停止工作”，在后台时。 我的逻辑得到的唯一错误是下面的一个，它是关于解析（parse.com），我用它来获取来自互联网数据库中的一些信息。

我不明白是什么问题。 我从它失去了天，甚至因为这个问题似乎是解析库中，而不是在我的代码

logcat的输出：

编辑：我发现，问题出在下面的代码，因为评论的try / catch块不会出现问题。 希望可以有人帮帮我。

这是我的应用程序类的代码： 

    package com.alain.ama.caccamo;

import com.crashlytics.android.Crashlytics;
import com.parse.Parse;
import com.parse.ParseACL;
import com.parse.ParseInstallation;
import com.parse.ParseUser;
import android.app.Application;

public class AmaCaccamoApplication extends Application {

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

        Crashlytics.start(this);

       try {            
        // / Add your initialization code here
        Parse.initialize(this, "TM918DSLjSCTe61lDTqwzxGRYe23************", "a5wmBOm7ZKBJfcBAjHW2C1e1Q7Rr************");

        ParseUser.enableAutomaticUser();
        ParseACL defaultACL = new ParseACL();

        // If you would like all objects to be private by default, remove this
        // line.
        defaultACL.setPublicReadAccess(true);

        ParseACL.setDefaultACL(defaultACL, true);
        ParseInstallation.getCurrentInstallation().saveInBackground();


        } catch (Exception e) {
            e.printStackTrace();
        }
    }

}

Answer 1:

我曾经有过同样的问题。 检查是否为空。 见注释代码： 

   private void processPush(Context context, Intent intent) {
    String msg = "";
    try {
        // Added null check here
        if (intent.getExtras().getString("com.parse.Data") !=null) {
            JSONObject json = new JSONObject(intent.getExtras().getString("com.parse.Data"));
            Iterator itr = json.keys();
            while (itr.hasNext()) {
                String key = (String) itr.next();
                Log.d(TAG, "..." + key + " => " + json.getString(key));
                if (key.equals("customdata")) {
                    msg = json.getString(key);
                }
            }
        }
    } catch (JSONException e) {
        Log.d(TAG, "JSONException: " + e.getMessage());
    }
    generateNotification(context, msg);
}
