我使用谷歌通知，在我的应用程序，而到现在为止我已经在清单中过这样的：

 ＆LT;！ -  GCM  - ＆GT;
＆LT;使用-权限的Andr​​oid：名称=android.permission.GET_ACCOUNTS/＆GT; ＆LT;！ -  GCM需要一个谷歌帐户。 - ＆GT;
＆LT;使用-权限的Andr​​oid：名称=android.permission.WAKE_LOCK/＆GT; ＆LT;！ - 进入休眠状态保持处理器接收到消息时。 - ＆GT;
＆LT;使用-权限的Andr​​oid：名称=com.google.android.c2dm.permission.RECEIVE/＆GT; ＆LT;  - ！此应用程序有权限注册并接收数据信息。 - ＆GT;

＆LT;！ - 创建一个自定义权限所以只有这个程序可以接收它的消息。注：APP_PACKAGE.permission.C2D_MESSAGE  - ＆GT;
＆LT;允许机器人：名称=com.myapp.permission.C2D_MESSAGE安卓的ProtectionLevel =签名/＆GT;
＆LT;使用-权限的Andr​​oid：名称=com.myapp.permission.C2D_MESSAGE/＆GT;
＆LT;！ -  END GCM  - ＆GT;
 

它完美工作，直到我更新了我的Nexus 7至Android 5.0。 现在，当我尝试安装此设备与Eclipse的应用程序，我得到这个错误：

  

INSTALL_FAILED_DUPLICATE_PERMISSION烫发= com.myapp.permission.C2D_MESSAGE PKG = com.myapp

我不明白什么是错的......这是工作，直到完美的Andr​​oid 5.0。 我知道，我在两行用 C2D_MESSAGE ，许可和使用-许可，但我复制从原来的谷歌GCM指南，code，所以它一定是好的。

解决方案

我已经找到了解决方案，为我工作。

在我的设备（的Nexus 7）的Andr​​oid 5.0。棒棒堂我按照下面的步骤。

卸载应用程序后，你可能会发现应用程序名在下载的应用程序列表设置页。

进入设置 应用 在列表中，你会发现底部的 YourApp 与未安装标签 开启 点击 OptionMenu 并选择卸载所有用户

在这过程中，我成功地安装新的应用程序，它运行良好。

欢迎来ping我，如果有任何疑问白羊座。谢谢你。

I am using Google notifications in my app, and until now I have had this 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 -->

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

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 copied that code from the original Google GCM guide, so it must be fine.

解决方案

I've found a solution that works for me.

In My Device (Nexus 7) Android 5.0. Lollipop I follow the following steps.

After Uninstalling App You may find App Name under Apps List of the Downloaded Tab.

Go to Settings Apps At bottom of the list you will find YourApp with a "NOT INSTALLED" Tag Open Click on OptionMenu and Select "Uninstall for all Users"

After that process I successfully install the new app and it's running well.

Feel free to ping me if any doubt aries. Thanks.
