INSTALL_FAILED_DUPLICATE_PERMISSION... C2D_MESSAGE [英] INSTALL_FAILED_DUPLICATE_PERMISSION... C2D_MESSAGE

问题描述

我在我的应用中使用了 Google 通知，到目前为止我已经在清单中完成了以下操作:

I am using Google notifications in my app, and until now I have done below in the manifest:

<!-- 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 -->

在我将 Nexus 7 更新到 Android 5.0 之前，它运行良好.
现在，当我尝试使用 Eclipse 在此设备中安装该应用程序时，出现此错误:

It worked perfectly until I updated my Nexus 7 to Android 5.0.
Now when I try to install the app in this device with Eclipse, I get this error:

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

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

我不明白有什么问题?它在 Android 5.0 之前一直运行良好.
我知道我在两行中使用 C2D_MESSAGE，permission 和 uses-permission 但我已经从原始 Google GCM 指南中复制了该代码，所以应该没问题.

I don't understand what is wrong? It was working perfectly until Android 5.0.
I know that I am using C2D_MESSAGE in two lines, permission and uses-permission but I have copied that code from the original Google GCM guide, so it must be fine.
