implements DataApi.DataListener MessageApi.MessageListener CapabilityApi.CapabilityListener ChannelApi.ChannelListener
Receives events from other nodes, such as data changes, messages or connectivity events.
The life-cycle of this service is managed by Android Wear. This service will be bound to and events delivered as a result of various Android Wear events, including data, messages and events indicating a device has connected or disconnected from the Android Wear network.
Applications expecting to be notified of events while in the background should extend this
class. Activities and other short-lived Android components may use
addListener(DataClient.OnDataChangedListener)
,
addListener(MessageClient.OnMessageReceivedListener)
to receive events for a
limited period of time.
Implementors could use a LocalBroadcastManager
to dispatch events to other components in an application.
For best performance, limit the number of listeners and use mutually exclusive filters where there are multiple listeners. A common pattern is to use prefix filters to listen to different namespaces within an application.
Example manifest entry:
android:pathPrefix is optional.
<service android:name=".MyWearableListenerService" > <intent-filter> <!-- listeners receive events that match the action and data filters --> <action android:name="com.google.android.gms.wearable.DATA_CHANGED" /> <action android:name="com.google.android.gms.wearable.MESSAGE_RECEIVED" /> <action android:name="com.google.android.gms.wearable.CAPABILITY_CHANGED" /> <action android:name="com.google.android.gms.wearable.CHANNEL_EVENT" /> <data android:scheme="wear" android:host="*" android:pathPrefix="/prefix" /> </intent-filter> </service>

Public Methods
public Looper getLooper ()
This method is used to retrieve the looper all callbacks will run on. The default behavior is to construct a new background thread the first time called and use that thread. If a different looper is desired, subclasses should override this method.
public void onCapabilityChanged (CapabilityInfo capabilityInfo)
public void onChannelClosed (Channel channel, int closeReason, int appSpecificErrorCode)
Called when a channel is closed. This can happen through an explicit call to
close(GoogleApiClient)
or
close(GoogleApiClient, int)
on either side of the connection, or due to
disconnecting from the remote node.
Parameters
channel | |
---|---|
closeReason | the reason for the channel closing. One of
CLOSE_REASON_DISCONNECTED ,
CLOSE_REASON_REMOTE_CLOSE , or
CLOSE_REASON_LOCAL_CLOSE . |
appSpecificErrorCode | the error code specified on
close(GoogleApiClient) , or 0 if closeReason is
CLOSE_REASON_DISCONNECTED . |
public void onChannelClosed (ChannelClient.Channel channel, int closeReason, int appSpecificErrorCode)
Called when a channel is closed.
Parameters
channel | the ChannelClient.Channel
that was closed. |
---|---|
closeReason | the reason for the input closing. One of
CLOSE_REASON_DISCONNECTED ,
CLOSE_REASON_REMOTE_CLOSE ,
CLOSE_REASON_LOCAL_CLOSE , or
CLOSE_REASON_NORMAL . |
appSpecificErrorCode | the error code specified on
close(ChannelClient.Channel, int) , or 0 if closeReason is
CLOSE_REASON_DISCONNECTED or
CLOSE_REASON_NORMAL . |
public void onChannelOpened (Channel channel)
Called when a new channel is opened by a remote node.
public void onChannelOpened (ChannelClient.Channel channel)
Called when a new channel is opened by a remote node.
Parameters
channel | the ChannelClient.Channel
that was opened. |
---|
public void onCreate ()
public void onDataChanged (DataEventBuffer dataEvents)
Receives data changed events. The provided buffer will be closed after this method
completes. Use freeze()
on items in the buffer to use them outside of this callscope.
Multiple data events may delivered in a single call and may only contain final-state
modifications of a data item. (Eg, multiple calls to putDataItem changing the value of
the data item's getData()
may only appear as a single event, with the last modification expressed).
Applications needing to track the of all its data items, may use
getDataItems(GoogleApiClient)
on boot to retrieve all existing data
items.
public void onDestroy ()
public void onInputClosed (Channel channel, int closeReason, int appSpecificErrorCode)
Called when the input side of a channel is closed.
Parameters
channel | |
---|---|
closeReason | the reason for the input closing. One of
CLOSE_REASON_DISCONNECTED ,
CLOSE_REASON_REMOTE_CLOSE ,
CLOSE_REASON_LOCAL_CLOSE , or
CLOSE_REASON_NORMAL |
appSpecificErrorCode | the error code specified on
close(GoogleApiClient) , or 0 if closeReason is
CLOSE_REASON_DISCONNECTED or
CLOSE_REASON_NORMAL . |
public void onInputClosed (ChannelClient.Channel channel, int closeReason, int appSpecificErrorCode)
Called when the input side of a channel is closed.
Parameters
channel | the ChannelClient.Channel
whose input was closed. |
---|---|
closeReason | the reason for the input closing. One of
CLOSE_REASON_DISCONNECTED ,
CLOSE_REASON_REMOTE_CLOSE ,
CLOSE_REASON_LOCAL_CLOSE , or
CLOSE_REASON_NORMAL . |
appSpecificErrorCode | the error code specified on
close(ChannelClient.Channel, int) , or 0 if closeReason is
CLOSE_REASON_DISCONNECTED or
CLOSE_REASON_NORMAL . |
public void onMessageReceived (MessageEvent messageEvent)
Receives message events.
public void onOutputClosed (Channel channel, int closeReason, int appSpecificErrorCode)
Called when the output side of a channel is closed.
Parameters
channel | |

CLOSE_REASON_DISCONNECTED ,
CLOSE_REASON_REMOTE_CLOSE ,

public void onOutputClosed (ChannelClient.Channel channel, int closeReason, int appSpecificErrorCode)
Called when the output side of a channel is closed.
Parameters

whose output was closed. |
