Surprisingly, it was very easy to do that. Just a quick look through the WebView/WebViewClient docs and you've quickly got your answer.
Set up your WebView with a new WebViewClient by calling:
1.webView.setWebViewClient(new NoErrorWebViewClient());And here is the subclassed WebViewClient which handles errors:
01.class NoErrorWebViewClient extends WebViewClient {02. @Override03. public void onReceivedError(WebView view, int errorCode, String description, String failingUrl) {04. Log.e(String.valueOf(errorCode), description);05. 06. // API level 5: WebViewClient.ERROR_HOST_LOOKUP07. if (errorCode == -2) {08. String summary = "<html><body style='background: black;'><p style='color: red;'>Unable to load information. Please check if your network connection is working properly or try again later.</p></body></html>"; view.loadData(summary, "text/html", null);09. return;10. }11. 12. // Default behaviour13. super.onReceivedError(view, errorCode, description, failingUrl);14. }15.}And the result is...
Just a reminder that within the error handler you can also load a local resource/asset rather than building the HTML string.
Now, go back to doing more magic!
Update 24/01/2013: Moved super.onReceivedError() to the end of the call to prevent flickering.
