Question

为什么此代码有效：

ActivityCompat.requestPermissions(thisActivity,
            new String[]{Manifest.permission.READ_CONTACTS},
            666);

## In the manifest
<uses-permission android:name="android.permission.READ_CONTACTS" />

并且此代码无效：

ActivityCompat.requestPermissions(thisActivity,
            new String[]{Manifest.permission.BIND_NOTIFICATION_LISTENER_SERVICE},
            666);

## In the manifest
<uses-permission android:name="android.permission.BIND_NOTIFICATION_LISTENER_SERVICE" />

第一个代码段启动请求权限活动，询问读取联系人权限。最后一个代码段不显示活动，在日志中有以下消息：

10-16 12:19:48.061 1138-3635/? I/ActivityManager: START u0 {act=android.content.pm.action.REQUEST_PERMISSIONS pkg=com.google.android.packageinstaller cmp=com.google.android.packageinstaller/com.android.packageinstaller.permission.ui.GrantPermissionsActivity (has extras)} from uid 10147 on display 0

那么，我应该做什么来询问通知权限？目标API是v24，最小sdk版本是23。

Answer 1

嗯，运行时权限仅被要求提供危险权限，因为通知服务不是您不需要的危险权限。这是所有危险和非危险权限的列表。

https://developer.android.com/guide/topics/security/permissions.html#normal-dangerous

P.S。无论许可是危险还是正常，都必须在舱单中声明，唯一的区别在于运行时请求。

Answer 2

来自documentation

BIND_NOTIFICATION_LISTENER_SERVICE

String BIND_NOTIFICATION_LISTENER_SERVICE

Must be required by an NotificationListenerService, to ensure that only the system can bind to it.

这意味着它不一定需要在运行时由用户授予。相反，它需要在NotificationListenerService下的manifest.xml中声明。像这样的东西，

<service android:name=".NotificationListener"
          android:label="@string/service_name"
          android:permission="android.permission.BIND_NOTIFICATION_LISTENER_SERVICE">
     <intent-filter>
         <action android:name="android.service.notification.NotificationListenerService" />
     </intent-filter>
 </service>
