【问题描述】：

我可以推送简单的推送通知，但无法推送 URL 以在浏览器中打开它。

我在网上看过很少的教程，他们建议创建自定义 JSON 接收器类。谁能告诉我该怎么做？

MainActivity.java

 package com.example.pushnotificationdemo;



import com.example.pushnotificationdemo.R;
import com.parse.ParseAnalytics;
import com.parse.ParseInstallation;
import com.parse.PushService;

import android.content.Intent;
import android.net.Uri;
import android.os.Bundle;
import android.support.v7.app.ActionBarActivity;
import android.view.Window;
import android.webkit.WebChromeClient;
import android.webkit.WebView;
import android.webkit.WebViewClient;

public class MainActivity extends ActionBarActivity 

    WebView webframe;



    @Override
    protected void onCreate(Bundle savedInstanceState) 
        super.onCreate(savedInstanceState);



        setContentView(R.layout.activity_main);

        ParseAnalytics.trackAppOpenedInBackground(getIntent());

        PushService.setDefaultPushCallback(this, MainActivity.class);
        ParseInstallation.getCurrentInstallation().saveInBackground();



        /** Cerco l'elemento in /res/layout/main.xml */
        webframe = (WebView) findViewById(R.id.webview);

        /** javascript abilitato (ma non flash) */
        webframe.getSettings().setJavaScriptEnabled(true);



        /** Simulo il webbrowser chrome di android*/
        webframe.setWebChromeClient(new WebChromeClient()); 
        webframe.setWebViewClient(new WebViewClient()); 

        /** Assegno l'url di apertura del webframe */
        webframe.loadUrl("http://www.daiugs.com");






    

ParseApp.java

package com.example.pushnotificationdemo;

import com.parse.Parse;
import com.parse.ParseACL;
import com.parse.ParseUser;

import android.app.Application;

public class ParseApp extends Application

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

        Parse.initialize(this, "Ym4IsX0r5dGLxa8RDtj....",
                "s9DpBvn8HI0Uu......");

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

        defaultACL.setPublicReadAccess(true);

        ParseACL.setDefaultACL(defaultACL, true);

        </receiver>

    </application>

</manifest>

【参考方案1】：

推送时发送

data: 
    alert: "Android Push Gets Major Refresh",
    url: "http://blog.parse.com",
  

并将其添加到您的 mainActivity 中

Intent intent = getIntent();
Bundle extras = intent.getExtras();
String jsonData = extras.getString("com.parse.Data");
JSONObject json = new JSONObject(jsonData);
String pushStore = json.getString("url");
if(pushStore!=null) 
    Intent browserIntent = new Intent(Intent.ACTION_VIEW, Uri.parse(pushStore));
  startActivity(browserIntent);
