大佬教程收集整理的这篇文章主要介绍了是否可以在 kivy webiew 中与 javascript 和 python 交互？，大佬教程大佬觉得挺不错的，现在分享给大家，也给大家做个参考。
我需要创建一个单独的java文件并添加它然后用jnius调用它吗？我不太了解androID java有没有其他人这样做过？
这是我尝试过的

更新
这就是它在空白屏幕上的作用，JsCallBACk() 不会触发
我通过 jnius 导入了 JavaScripTinterface
我想我想使用 @ 函数，但不知道该怎么做
暂无找到可以解决该程序问题的有效方法，小编努力寻找整理中！
如果你已经找到好的解决方法，欢迎将解决方案带上本链接一起发送给小编。
