java - Android c2dm 未知权限

Question

我看到有人发布了一个非常相似的问题，但他的解决方案没有帮助。我在 logcat 的警告部分看到未知权限。

unknown permission com.google.android.c2dm.permission.C2D_MESSAGE in package com.upmc

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.upmc"
android:versionCode="1"
android:versionName="1.0" >

<uses-permission android:name="android.permission.INTERNET" />
<permission android:name="com.upmc.permission.C2D_MESSAGE" android:protectionLevel="signature" />
<uses-permission android:name="com.google.android.c2dm.permission.RECEIVE" />
<uses-permission android:name="com.google.android.c2dm.permission.C2D_MESSAGE" />

     <!-- registers the receiving class for a c2dm broadcast intent to be .C2DMBroadcastReceiver.-->

    <receiver android:name=".C2DMReceiver" android:permission="com.google.android.c2dm.permission.SEND">
        <intent-filter>
            <!--Action String being listened for, then calls parent registered receiver -->
            <action android:name="com.google.android.c2dm.intent.RECEIVE"/>
            <!-- still don't understand this  -->
            <catagory android:name="com.upmc" />
            <!-- must unregister intent filter when app is not running -->
        </intent-filter>
        <intent-filter>
            <!-- change here...action string pre-set by google?-->
            <action android:name="com.google.android.c2dm.intent.REGISTRATION" />
            <!-- specify under what circumstances the action should be serviced -->
            <catagory android:name="com.upmc" />
        </intent-filter>
    </receiver>

很难阅读，我知道抱歉!

我也没有从 Google 得到任何类型的回复。我已经注册了这个应用程序并登录了谷歌帐户。有什么想法吗？

Answer 1

根据this article ，要在应用程序中使用C2DM必须注册以下权限

1. com.google.android.c2dm.permission.RECEIVE
2. android.permission.INTERNET
