我在我的应用中使用Google通知,直到现在我在清单中完成了以下操作:

<!-- GCM -->
<uses-permission android:name="android.permission.GET_ACCOUNTS" /> <!-- GCM requires a Google account. -->
<uses-permission android:name="android.permission.WAKE_LOCK" /> <!-- Keeps the processor from sleeping when a message is received. --> 
<uses-permission android:name="com.google.android.c2dm.permission.RECEIVE" /> <!-- This app has permission to register and receive data message. --> 

<!-- Creates a custom permission so only this app can receive its messages. NOTE: APP_PACKAGE.permission.C2D_MESSAGE -->   
<permission android:name="com.myapp.permission.C2D_MESSAGE" android:protectionLevel="signature" />
<uses-permission android:name="com.myapp.permission.C2D_MESSAGE" />    
<!-- END GCM -->

它完美运行,直到我将Nexus 7更新为Android 5.0.
现在,当我尝试使用Eclipse在此设备中安装应用程序时,出现此错误:

INSTALL_FAILED_DUPLICATE_PERMISSION perm = com.myapp.permission.C2D_MESSAGE pkg …

我正在测试适用于Android的新Google Maps API V2,并在应用启动时收到此消息:

这是在4.1模拟器上运行.
