JavaScript接口浏览器不工作4.2.2 [英] JavaScript Interface to a Browser not working in 4.2.2

问题描述

我测试过我的JavaScript界面​​的Andr​​oid 2.3,4.0,4.1设备工作完美
但在星系S4是4.2.2不工作
我试着打电话给我从index.html的原生界面
onload事件，但它说，对象不确定。

I had tested my javascript interface working perfectly in android 2.3,4.0,4.1 devices but not working in galaxy S4 which is 4.2.2 i tried calling my native interface from index.html onload but it says object undefined.

我打电话从浏览器这个功能。

i am calling this function from browser

window.onload = function() {
  window.jsinterface.getSomeString("testing from index.html");
}

这行code在我的活动recieving数据

this line of code in my activity for recieving data

final class JavaScriptInterface {
    JavaScriptInterface() {}

    public void getSomeString(String data) {
        Log.d("yahoo", "DAta" + data);
        Toast.makeText(Testing.this, "getsomestring:"+data, Toast.LENGTH_SHORT).show();
    }
}

对于除这个方法从浏览器发送数据的任何建议也将是对我有帮助。
或指导我该怎么做。

any suggestion for sending data from browser except this method would also be helpful for me. or guide me what to do.

推荐答案

如果你的的android：targetSdkVersion 设置为17或更高，则需要添加 @JavascriptInterface 注释 getSomeData（），如描述<一个href=\"https://developer.android.com/reference/android/webkit/WebView.html#addJavascriptInterface%28java.lang.Object,%20java.lang.String%29\">in文档。

If your android:targetSdkVersion is set to 17 or higher, you need to add the @JavascriptInterface annotation to getSomeData(), as is described in the documentation.
