android - 为什么 CordovaWebViewClient 不再适用于 Cordova 6

Question

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，我将 www 目录托管到 Web 服务器，并从那里与 cordova 插件进行交互(barcodescanner、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，我已将项目从 cordova 3.7 迁移到 cordova 6，但我发现上面的代码已损坏，如 CordovaWebViewClient、super.onPageStarted 等 无法解析符号。我还尝试了 CordovaWebViewImpl 并把自己弄糊涂了。

在谷歌上大量搜索后，我找到了大部分在 2011-14 年给出的解决方案，这些解决方案不适用。我找不到有用的 cordova 文档。

它被替换为 SystemWebViewClient

你应该这样做:

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);
    }
});
