Question

为什么不能在<application>标签中添加name属性

Answer 1

刚查了下google的开发者文档里面对这个name标签的解释
引用:
android:name
The fully qualified name of an Application subclass implemented for the application. When the application process is started, this class is instantiated before any of the application's components.
The subclass is optional; most applications won't need one. In the absence of a subclass, Android uses an instance of the base Application class.原来这个name不是我想的那样随随便便取得名字，一般都没有的（默认是android.app.Application），如果非要有的话，这个名字必须是继承自application的一个类名
比如
代码:
public class MyApp extends Application{
//TODO
}
然后才能在AndroidManifest.xml中配置这个application的name属性
代码:
<application android:name="MyApp" ...>
...
</application>
