Question

我跟随此tutorial并获得了WearableListenerService。我刚刚实现了onMessageReceived方法，并没有改变任何其他方法。

该服务的条目如下所示：

<service android:name=".WearableRemoteCommandListener"
    android:permission="android.permission.BIND_NOTIFICATION_LISTENER_SERVICE"
    android:enabled="true"
    android:exported="true">
    <intent-filter>
        <action android:name="com.google.android.gms.wearable.BIND_LISTENER"></action>
    </intent-filter>
</service>

application元素包含这个元数据元素：

<meta-data
    android:name="com.google.android.gms.version"
    android:value="@integer/google_play_services_version" />

但是当我向可穿戴者发送消息时，我得到了这个安全例外：

06-08 21:15:41.337      579-842/? W/ActivityManager﹕ Permission Denial: Accessing service ComponentInfo{net.bplaced.schlingel.wearabletest1/net.bplaced.schlingel.anmosela.WearableRemoteCommandListener} from pid=822, uid=10009 requires android.permission.BIND_NOTIFICATION_LISTENER_SERVICE

            at android.os.Looper.loop(Looper.java:135)
            at android.os.HandlerThread.run(HandlerThread.java:61)

我尝试添加导出和启用的属性，重新启动了可穿戴设备，但异常再次发生。是否缺少权限？我的设置有什么问题？

摆脱这条线

android:permission="android.permission.BIND_NOTIFICATION_LISTENER_SERVICE"

来自documentation

的

NotificationListenerService必须要求，以确保这一点只有系统可以绑定它。

应该调用onMessageReceived时的权限拒绝
