推荐答案

除非你有的禁用调试数据的在您的应用程序的每个元素都有一个范围（）函数可以调用找回该元素的范围。它也有一个喷油器，您可以使用取回喷油器实例您的应用程序（）功能。所以，试试这个：

Unless you have disabled debug data then each element in your app has a scope() function you can call to get back the scope for that element. It also has an injector() function you can use to get back the injector instance for your app. So try this:

javascript:angular.element('[ng-app]').injector().get('myService').hello()

这可能会是更好的暴露只是你需要访问窗口，虽然该功能。

It would probably be better to expose just the function that you need access to on the window though.

所以，你需要做的是这样的：

So then you would need to do something like this:

angular.module('myApp').service('myService', function(yourDependencies..., $window) {
  //Your code 

  $window.hello = this.hello;
});

那么你的Andr​​oid code成为本：

Then your Android code becomes this:

view.loadUrl("javascript:hello()");
