Chromium For Android addPossivelyUnsafeInterface 不工作

问题描述

嘿，我正在为 Android 构建 Chromium，我想弄清楚为什么 Javascript 接口不允许我在 Chrome Activity 类的网页中注入 javascript .. 即使我单独调用 tab.getWebContents().evaluateJavaScript() ，浏览器死机。有没有办法成功实现这一目标？下面是我的代码片段

  import org.chromium.content.browser.JavascriptInterface;

  // Chrome Activity
  public abstract class ChromeActivity<C extends ChromeActivityComponent>
  ....

   @Override
   public void onDidFinishNavigation(Tab tab,String url,boolean isInMainFrame,boolean isErrorPage,boolean hasCommitted,boolean isSameDocument,boolean isFragmentNavigation,@Nullable Integer pageTransition,int errorCode,int httpStatusCode)
              { 

                    JavascriptInjector ji = JavascriptInjector.fromWebContents(tab.getWebContents());
                    tab.getWebContents().evaluateJavaScript("alert("Hello World");",null);
                    ji.setAllowinspection(true);

                    ji.addPossiblyUnsafeInterface(new MyJavaScriptInterface(ChromeActivity.this),"JS",JavascriptInterface.class);
             }


 class MyJavaScriptInterface {

     ChromeActivity context;
     public MyJavaScriptInterface(ChromeActivity activity) {
     this.context = activity;
  }

  @JavascriptInterface
  public void app(){
  int duration = Toast.LENGTH_SHORT;
  Toast toast = Toast.makeText(this.context,"Test",duration);
  toast.show();
  }
}
