Can an Android Service have multiple Permissions?
提问by Aymon Fournier
I have a service which both downloads a file and saves it, and it seems I can only specify one permission.
我有一项既下载文件又保存文件的服务，看来我只能指定一个权限。
<service android:enabled="true"
android:name=".DownloadService" android:permission="android.permission.INTERNET">
</service>
or
或者
<service android:enabled="true"
android:name=".DownloadService" android:permission="android.permission.WRITE_EXTERNAL_STORAGE">
</service>
I need both.
我两个都需要。

An Android Servicecan have multiple permissions, but permissions are granted at the application level, not at the Servicelevel.
一个 AndroidService可以有多个权限，但权限是在应用程序级别授予的，而不是在Service级别。
Your problem is that you are trying to grant permission to your Servicein the wrong place in the AndroidManifest.xmlfile.
您的问题是您试图Service在AndroidManifest.xml文件中的错误位置授予您的权限。
The android:permissionattribute of a Servicespecifies the permission that an entity must have to use the service, not a permission granted to the Service.
a 的android:permission属性Service指定实体必须拥有使用服务的权限，而不是授予 Service.
You grant permissions to all components your applicationat the top level of your AndroidManifest.xml:
您在您的顶级应用程序中授予对所有组件的权限AndroidManifest.xml：
<manifest
xmlns:android="http://schemas.android.com/apk/res/android"
package="com.yourdomain.yourapp" >
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
</manifest>
