寻找提供django模板的资源(Looking for a resource which provides django templates [closed])

 如果您使用的是DataApi.DataListener，则必须在连接GoogleApiClient后添加addListener。 类似于： Wearable.DataApi.addListener(mGoogleApiClient, this) 。 
 
 如果您正在使用WearableListenerService，请确保在接收/侦听方的AndroidManifest.xml中有类似的代码，如下所示： 
 
<service android:name=".YourCustomWearableListenerService">
    <intent-filter>
        <action android:name="com.google.android.gms.wearable.DATA_CHANGED"/>
            <data android:scheme="wear" 
                  android:host="*" 
                  <!-- I believe pathPrefix is optional, removing it will make the service listener to all data change events -->
                  android:pathPrefix="/YourDataMapPathPrefix"/>
        </intent-filter>
</service>
 
 另请注意，只有在数据实际更改时才会调用onDataChanged 。 让我们说旧数据是（“Person”，“Bob”）并且用相同的数据（“Person”，“Bob”）替换它，然后onDataChanged将不会被触发，因为数据实际上没有改变。 但是如果放入（“Person”，“Bob2”）， onDataChanged将被触发。 

If you are using DataApi.DataListener, then you have to addListener after GoogleApiClient connected. Something like: Wearable.DataApi.addListener(mGoogleApiClient, this) inside your GoogleApiClient.ConnectionCallbacks.
 
If you are using WearableListenerService make sure you have similar code in your AndroidManifest.xml on the receiving/listening side as shown below:
 
<service android:name=".YourCustomWearableListenerService">
    <intent-filter>
        <action android:name="com.google.android.gms.wearable.DATA_CHANGED"/>
            <data android:scheme="wear" 
                  android:host="*" 
                  <!-- I believe pathPrefix is optional, removing it will make the service listener to all data change events -->
                  android:pathPrefix="/YourDataMapPathPrefix"/>
        </intent-filter>
</service>
 
Also keep in mind that onDataChanged will get call only if the data is ACTUALLY changed. Let's said that the old data is ("Person", "Bob") and you replace it with same data ("Person", "Bob"), then onDataChanged will not get triggered since the data does not change in fact. But onDataChanged will get triggered if you put ("Person", "Bob2") instead.
