【问题描述】：

在我的 android 应用中，当我尝试在 logcat 中接收推送通知时出现此错误：

6-22 14:38:16.016 6570-6570/com.tekinarslan.material.sample E/com.parse.ManifestInfo﹕无法使用 GCM 进行推送，因为应用程序 manifest 缺少一些必需的声明。请确保 这些权限被声明为根的孩子 元素： 另外，请确保将这些服务和广播接收器声明为元素的子元素： 06-22 14:38:16.021 6570-6570/com.tekinarslan.material.sample E/com.parse.PushService﹕ 尝试使用推送，但此应用未配置推送，原因如下： 未为此应用配置推送，因为应用清单是 缺少必需的声明。请添加以下声明 到您的应用清单以支持 GCM 或 PPNS 进行推送（或两者）。 要启用 GCM 支持，请确保这些权限是 声明为根元素的子元素： 另外，请确保将这些服务和广播接收器声明为元素的子元素： 要启用 PPNS 支持，请确保将这些权限声明为根元素的子元素： 另外，请确保将这些服务和广播接收器声明为元素的子元素：

【参考方案1】：

您的自定义接收器需要在意图过滤器中执行以下操作：

<receiver
  android:name=".ParseReceiver"
  android:exported="false">
  <intent-filter>
    <action android:name="com.parse.push.intent.RECEIVE"/>
    <action android:name="com.parse.push.intent.DELETE"/>
    <action android:name="com.parse.push.intent.OPEN"/>
    ...
  </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"/>

    <category android:name="at.a1telekom.android.newsroom"/>
  </intent-filter>
</receiver>

编辑：

您是否订阅这样的解析？

Parse.initialize(context, appId, clientKey);    
ParsePush.subscribeInBackground( yourChannels, new SaveCallback() ...);

已添加，没有错误但通知仍未到达.. @Rithe

啊，我看到还是少了点什么。我更新了我的答案。也尝试添加 GcmBroadcastReceiver 设置。

【参考方案2】：

清单中缺少给定的代码。在标记之前的清单文件底部包含给定的代码。

 <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.tutorials.pushnotifications" to match your app's package name. -->
            <category android:name="com.tekinarslan.material.sample" />
        </intent-filter>
    </receiver>
    <receiver
        android:name="com.tekinarslan.material.sample.NotificationReceiver"
        android:exported="false" >
        <intent-filter>
            <action android:name="com.tekinarslan.material.sample.UPDATE_STATUS" />
        </intent-filter>
    </receiver>

现在我没有错误但通知仍然没有到达...@Rasika

这行你加了吗，PushService.setDefaultPushCallback(this, context);在应用程序类中？这是推动工作的强制性要求。

parse.com/docs/android/api/com/parse/PushService.html ，你可以得到答案。如果您使用的是最新的解析 SDK
