我已经把我的XML正确的id作为wvBrowser和我在我的Android清单XML文件的权限。是否有人知道这个问题？先谢谢了。
I have put in my xml the proper id as wvBrowser and I have the user permission in my android Manifest xml file. Does anybody know the problem? Thanks in advanced.
推荐答案
您不能在可穿戴使用的WebView，检查这里无法使用的功能列表：
https://developer.android.com/training/wearables/apps/index.html
You can't use WebView on a wearable, check the list of unavailable features here: https://developer.android.com/training/wearables/apps/index.html
此外，你不能直接从可穿戴设备连接到互联网，它不具备互联网接入，只能从同伴手持接收数据。
Also, you can't connect to the internet directly from a wearable device, it doesn't have an internet access and can only receive data from the companion handheld.
编辑：
其实，我看只有一个办法做到这一点：
Actually, I see only one way to do it:
- 在手持设备加载一个HTML页面，并将其转移到一个可穿戴使用Wearable.DataApi
- 显示器上使用可穿戴（可定制）第三方库的HTML页面。可能是从这个答案将是有益这里的项目。
- Load an html page on a handheld and transfer it to a wearable using Wearable.DataApi
- Display the page on a wearable using(may be customized) a third-party html library. May be the project from this answer will be useful here.
