Permission Denial when onMessageReceived should be called

Question

I'm following this tutorial and got a WearableListenerService. I just implemented the onMessageReceived method and didn't change anything else.

The entry for the service looks like this:

<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>

The application element contains this meta-data element:

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

But when I send a message to the wearable I get this security exception:

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

I tried to add the exported and enabled attribute, restarted the wearable but the exception happens again. Is there a permission missing? What is wrong with my setup?

Answer 1

get rid of this line

android:permission="android.permission.BIND_NOTIFICATION_LISTENER_SERVICE"

from the documentation

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