kivy for android webview
Kivy 的浏览器，支持局部显示，非原创，翻阅整合了几个源码整理而成。
源码只是跑一个webview的示例，所有控件均没有做事件反馈，自行添加。
P4A 需要自己根据自己路径修改。
google translate:
Kivy's browser supports partial display, non-original, and a combination of several source code.
The source code is just an example of running a webview. All controls have no event feedback and are added by themselves.
P4A needs to modify it according to its own path.
