无法获取推送通知文本

Question

我已经创建了一个示例Android应用程序，用于接收来自解析的推送消息。我按照this video tutorial。该应用程序工作正常，我能够接收推送通知。是

所需的类，如下所示：

ParseApplication类：

public class ParseApplication extends Application { 

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

     // Add your initialization code here 
     Parse.initialize(this, "ygdC4y3uzCe0TOEPOfB1U469Gg5ZJGxF2OGlNKCG", "Tk5ZlDiWWVJm2Xio5IiXk0KI5JM1jrvGPOSpFxzE"); 

     PushService.setDefaultPushCallback(ParseApplication.this, SampleClass.class); 



     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); 
    } 

} 

ParseStarterProjectActivity类：

public class ParseStarterProjectActivity extends Activity { 
    /** Called when the activity is first created. */ 
    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.main); 

     ParseAnalytics.trackAppOpened(getIntent()); 


    } 
} 

SampleClass类：

public class SampleClass extends Activity { 

    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_sample_class); 
    } 

    @Override 
    public boolean onCreateOptionsMenu(Menu menu) { 
     // Inflate the menu; this adds items to the action bar if it is present. 
     getMenuInflater().inflate(R.menu.sample_class, menu); 
     return true; 
    } 

} 

的清单文件：

       <action android:name="android.intent.action.USER_PRESENT" /> 
      </intent-filter> 
     </receiver> 
     <receiver 
      android:name="com.parse.GcmBroadcastReceiver" 
      android:permission="com.google.android.c2dm.permission.SEND" > 
      <intent-filter> 
       <action android:name="com.google.android.c2dm.intent.RECEIVE" /> 
       <action android:name="com.google.android.c2dm.intent.REGISTRATION" /> 

       <!-- IMPORTANT: Change "com.parse.starter" to match your app's package name. --> 
       <category android:name="com.parse.starter" /> 
      </intent-filter> 
     </receiver> 

     <activity 
      android:name="com.parse.starter.SampleClass" 
      android:label="@string/title_activity_sample_class" > 
     </activity> 
    </application> 

</manifest> 

现在我想，当用户收到他们得到来自推送通知文本。我应该怎么做才能从通知中获取文本？

这是推送通知服务器的url。我甚至去过this。

我不得不改变SampleClass活动这样的：

public class SampleClass extends Activity { 

    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_sample_class); 

     Intent intent = getIntent(); 
     Bundle extras = intent.getExtras(); 
     String jsonData = extras.getString("com.parse.Data"); 

     Log.i("Data Received:", jsonData); 

    } 

    @Override 
    public boolean onCreateOptionsMenu(Menu menu) { 
     // Inflate the menu; this adds items to the action bar if it is present. 
     getMenuInflater().inflate(R.menu.sample_class, menu); 
     return true; 
    } 

其余的是因为它是。我提到了this link。
