我有一个自定义类来覆盖CordovaWebViewClient提供的方法shouldOverrideUrlLoading。
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);
}
在我升级到最新版本的Cordova(3.6.3)之前,它一直运行良好。现在不再调用函数shouldOverrideUrlLoading,但是在调试代码时,我可以看到在Cordova库(CordovaWebViewClient类)中正在执行相同的函数。
这是我改写Cordova网络客户端的方法:
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);
}
我今天升级到3.6.3后遇到了同样的问题。它查看了Cordova源代码以弄清楚为什么它被破坏了。在某种程度上init
,引入了一种新方法,该方法需要从config.xml中读取一堆参数。如果您的代码未调用该方法,则在加载URL时会遇到这种initIfNecessary
情况,这将覆盖已设置的所有自定义客户端。
从他们的代码:
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());
}
}
makeWebViewClient
即使您可能已经设置了自己的客户端,也可以看到被称为。
我用以下方法解决了这个问题:
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());
并删除了已弃用的Config.init(activity);
。
希望这可以为您节省一些我今天浪费的时间。
