添加的接口中的所有方法都没有使用@ android.webkit.JavascriptInterface注释;它们在API 17中不可见 [英] None of the methods in the added interface have been annotated with @android.webkit.JavascriptInterface; they will not be visible in API 17

问题描述

我正在使用webview并希望加载一个JScode以在该webview中显示。但是我遇到了API16以上的问题。它从不加载JS页面。它给了我一个错误：

I am using a webview and want to load a JScode to show in that webview. However I am getting a problem above API16.It never loads the JS page. It gives me an error:

这是我的代码：

        @JavascriptInterface

    public void loadWebviewUrl(){
            Map <String, String> extraEncryptionHeaders = new HashMap<String, String>();
            extraEncryptionHeaders.put("X-APP-DEVICETYPE", "ANDROID"); 
            appVersionname=CommonMethods.getAppVersion(WebPayUActivity.this);
            extraEncryptionHeaders.put("X-APP-APPVERSIONNAME", appVersionname); 
            extraEncryptionHeaders.put("X-DEVICE", Constant.ANDROIDID); 
            extraEncryptionHeaders.put(Constant.HEADER_SECURITY_KEY, Constant.SECURITY_HASH_VALUE);
            mWebView.loadUrl(mPayUrl, extraEncryptionHeaders);

**//getting error in this line that has been mentioned above**
            mWebView.addJavascriptInterface(new Wscript(WebPayUActivity.this),
                    "Android");
            screenDpi=CommonMethods.getResoltuion(this);
            mWebView.setWebViewClient(new MyWebViewClient(this));

            mImageView.setOnClickListener(new OnClickListener() {

                @Override
                public void onClick(View v) {
                    customAlertDialog();    
                }
            });
            mWebView.setWebChromeClient(new WebChromeClient());
        }

在阅读不同网站的解决方案后，我知道要添加注释。但在写完注释后，错误仍然是相同的。

After reading the solutions at different sites I got to know to add annotation. But after writing the annotation, the error is still the same.

任何人都可以检查并帮助我回来

Can anyone please check and help me back

谢谢

推荐答案

您必须添加

@SuppressLint("JavascriptInterface")

到您使用webView的公共方法对象。

to the your public methods which you used your webView object.
