错误清单文件项目

Question

我对清单文件错误，当我试图解决GCM问题：

error

error: Error: No resource found that matches the given name (at 'label' with value '@string/title_activity_main').

出现在这里的错误：

android:label="@string/title_activity_main" >

Answer 1

请将@string/title_activity_main添加到您的字符串资源。

Answer 2

您应该将res/values/strings.xml中的字符串作为item：

<?xml version="1.0" encoding="utf-8"?> 
<resources> 

    <string name="title_activity_main">My Main Activity</string> 

</resources>
