Q: shouldOverrideUrlLoading on custom Cordova CordovaWebViewClient not working anymore I had a custom class to override the method shouldOverrideUrlLoading, provided by CordovaWebViewClient. 
    public class CordovaCustomWebClient extends CordovaWebViewClient {

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

        @SuppressLint("DefaultLocale")
        @SuppressWarnings("deprecation")
        @Override
        public boolean shouldOverrideUrlLoading(WebView view, String url) {
            EventLogger.logMessage(getClass(), "--------------- shouldOverrideUrlLoading ---------------");
       return super.shouldOverrideUrlLoading(view, url);
       }

It was working fine until I've upgraded to the latest version of Cordova (3.6.3). Now the function shouldOverrideUrlLoading is no longer being called, but when I debug the code I can see that same function being executed in Cordova library (class CordovaWebViewClient).
Here is what I do to override Cordova's web client:
public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_web_application);

        cordovaWebView = (CordovaWebView) this.findViewById(R.id.mainView);

        Config.init(this);

        Application application = null;
        Bundle bundle = getIntent().getExtras();
        if (bundle != null) {
            application = (Application) bundle.get("key_application");
        }

        // Local Url to load application
        String url = "";
        if (application != null) {
            if (HubManagerHelper.getInstance().getApplicationHosted() == null) {
                MyApp app = (MyApp) getApplication();
                app.registerDefaultHubApplication();
            }
            url = String.format(WebServicesClient.URL_WEB_APPLICATION, HubManagerHelper.getInstance()
                    .getApplicationHosted(), application.getPath());
        }

        cordovaWebView.setWebViewClient(new CordovaCustomWebClient(this, cordovaWebView));

        // Listener to Download Web File with Native Component - Download Manager
        cordovaWebView.setDownloadListener(new DownloadListener() {
            public void onDownloadStart(String url, String userAgent, String contentDisposition, String mimetype,
                    long contentLength) {
                downloadAndOpenFile(WebApplicationActivity.this, url);
            }
        });

        String ua = cordovaWebView.getSettings().getUserAgentString();
        String appVersion = getAppVersion();
        String newUA = ua.concat(" MyApp." + appVersion);
        cordovaWebView.getSettings().setUserAgentString(newUA);
        if (savedInstanceState == null) {
            cordovaWebView.loadUrl(url);
        } else {
            ((LinearLayout) findViewById(R.id.view_loading)).setVisibility(View.GONE);
        }


A: I hit this exact same problem today after upgrading to 3.6.3. It took looking at the Cordova source code to figure out why this was broken. At some point a new method, init, was introduced, which takes a bunch of params read from your config.xml. If that method is not called by your code, then when a url is loaded it will hit the initIfNecessary case, which in turn will override any custom clients that were set.
From their code:
private void initIfNecessary() {
    if (pluginManager == null) {
        Log.w(TAG, "CordovaWebView.init() was not called. This will soon be required.");
        // Before the refactor to a two-phase init, the Context needed to implement CordovaInterface. 
        CordovaInterface cdv = (CordovaInterface)getContext();
        if (!Config.isInitialized()) {
            Config.init(cdv.getActivity());
        }
        init(cdv, makeWebViewClient(cdv), makeWebChromeClient(cdv), Config.getPluginEntries(), Config.getWhitelist(), Config.getExternalWhitelist(), Config.getPreferences());
    }
}

You can see that makeWebViewClient is called, even though you may have already set your own client.
I solved this with:
ConfigXmlParser parser = new ConfigXmlParser();
parser.parse(activity);

CordovaInterface cordova = (CordovaInterface) activity;
init(cordova, new WFWebViewClient(cordova, this), makeWebChromeClient(cordova),
    parser.getPluginEntries(), parser.getInternalWhitelist(), parser.getExternalWhitelist(),
    parser.getPreferences());

And removed the deprecated use of Config.init(activity);.
Hope this saves you some of the time I've wasted today.
