我已经尽可能接近 Google 的示例来实现 GCM，但默认的 GCMBroadcastReceiver 由于缺少 WAKE_LOCK 权限而抛出 SecurityException。不过，我在我的清单中需要它，所以 AFAIK 它应该在运行时拥有该权限。这是我的清单的相关部分：

<permission
    android:name="PACKAGENAME.permission.C2D_MESSAGE"
    android:protectionLevel="signature" />

<uses-permission android:name="PACKAGENAME.permission.C2D_MESSAGE" />

<permission
    android:name="android.permission.WAKE_LOCK"
    android:protectionLevel="signatureOrSystem" />

<uses-permission android:name="android.permission.WAKE_LOCK" />
<uses-permission android:name="com.google.android.c2dm.permission.RECEIVE" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.CAMERA" />
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.GET_ACCOUNTS" />

<application
    android:name=".App"
    android:icon="@drawable/app"
    android:label="@string/app_name"
    android:theme="@android:style/Theme.NoTitleBar" >
    <service android:name=".GCMIntentService" />

    <receiver
        android:name="com.google.android.gcm.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="PACKAGENAME" />
        </intent-filter>
    </receiver>

我在日志文件中看到的异常是：

我没有在我注册接收消息的活动的 onDestroy() 方法中调用 GCMRegistrar.onDestroy()。由于某种原因，导致它抱怨没有 WAKE_LOCK，但仅在 4.0.4 设备上。

你应该使用：

<uses-permission android:name="android.permission.WAKE_LOCK"/>

代替：

<permission
    android:name="android.permission.WAKE_LOCK"
    android:protectionLevel="signatureOrSystem" />
