android – 为什么CordovaWebViewClient不再在Cordova 6中工作了

我已经编写了自定义webviewclient类来覆盖cordova 3.7中的onPageStarted,onPageFinished等,它工作正常.

在下面的代码中,我已经将www目录托管到Web服务器并从那里交互cordova插件(条形码扫描器,nfc,蓝牙等).

public class MainActivity extends CordovaActivity {
    private WebView webView;

    @Override
    public void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);
        super.init();

        loadUrl("https://example.com");
    }

    public class CustomCordovaWebViewClient extends CordovaWebViewClient {

        public CustomCordovaWebViewClient(CordovaInterface cordova, CordovaWebView view) {
            super(cordova, view);
        }

        @Override
        public void onPageStarted(WebView view, String url, Bitmap favicon) {
            super.onPageStarted(view, url, favicon);
            Log.i("CSP Log", "onPageStarted: " + url);
        }

        @Override
        public void onPageFinished(WebView view, String url) {
            super.onPageFinished(view, url);
            Log.i("CSP Log", "onPageFinished: " + url);
        }

        @Override
        public void doUpdateVisitedHistory(WebView view, String url, boolean isReload){
            super.doUpdateVisitedHistory(view, url, isReload);
        }

        @Override
        public void onReceivedError(WebView view, int errorCode, String description, String failingUrl) {
            super.onReceivedError(view, errorCode, description, failingUrl);
        }

    }

}

一年后,我将项目从cordova 3.7迁移到cordova 6,但我发现上面的代码像CordovaWebViewClient一样被破坏,super.onPageStarted等无法解析符号.我也尝试过CordovaWebViewImpl并迷惑自己.

在google上搜索了很多我发现的解决方案,这些解决方案主要在2011-14中给出,不适用.我找不到cordova文档有用.

解决方法:

它被SystemWebViewClient取代

你应该做这样的事情：

SystemWebView wv = (SystemWebView)appView.getView();
wv.setWebViewClient(new SystemWebViewClient((SystemWebViewEngine)appView.getEngine()){
    @Override
    public void onPageStarted(WebView view, String url, Bitmap favicon) {
        super.onPageStarted(view, url, favicon);
        Log.i("CSP Log", "onPageStarted: " + url);
    }

    @Override
    public void onPageFinished(WebView view, String url) {
        super.onPageFinished(view, url);
        Log.i("CSP Log", "onPageFinished: " + url);
    }

    @Override
    public void doUpdateVisitedHistory(WebView view, String url, boolean isReload){
        super.doUpdateVisitedHistory(view, url, isReload);
    }

    @Override
    public void onReceivedError(WebView view, int errorCode, String description, String failingUrl) {
        super.onReceivedError(view, errorCode, description, failingUrl);
    }
});
