Most web site pages works fine on Android 4.4 (and newer) Chromium based webview. But recently I found a website page behaves different between 4.4 (or newer) and earlier Android system.
The webview on earlier Android system works as expected but on KitKat not. I believe there must be some tricks inside the page. But after weeks I am still stuck on this issue.. :(
Would you please help? Thank you very much.
Here are the codes:
WebView WV_test = (WebView) findViewById(R.id.WV_query);
WV_test.getSettings().setCacheMode(WebSettings.LOAD_NO_CACHE);
WV_test.getSettings().setDomStorageEnabled(true);
WV_test.getSettings().setJavaScriptEnabled(true);
WV_test.setWebViewClient(new WebViewClient() {
@Override
public void onPageStarted(WebView view, String url, Bitmap favicon) {
Log.v("attlog", "onPageStarted: url="+url);
super.onPageStarted(view, url, favicon);
}
@Override
public void onPageFinished(WebView view, String url) {
Log.v("attlog", "onPageFinished: url="+url);
super.onPageFinished(view, url);
}
@Override
public void onLoadResource(WebView view, String url) {
Log.v("attlog", "onLoadResource() url="+url);
super.onLoadResource(view, url);
}
});
String url="http://railway.hinet.net/ccancel_rt.jsp";
Log.v("attlog", "url="+url );
WV_test.loadUrl( url );The result on earlier webkit (i.e. 4.1) works as expected:
