See the documentation –Mannaz Aug 9 '11 at 10:51 The documentation you linked to does not agree with you. The ERROR_ constants are for various HTTP errors (e.g., ERROR_FILE_NOT_FOUND). –CommonsWare Aug 9 '11 at 11:32 5 The Paragraph says "The docs are wrong in this case.

82069: onReceivedError STILL does not receive HTTP Errors 23 people starred this issue and may be notified of changes. Back to list Status: Assigned Owner: mnaga...@android.comhttps://code.google.com/p/android/issues/detail?id=82069 > Type-Defect Priority-Medium ReportedBy-Developer Sign in to add a comment Reported by heath.bo...@gmail.com, Dec 8, 2014 Re-opening Issue 32755 [1] I re-tested this on Android 5.0 Lollipop, and the same behavior persists. The following curl command produces a 500: curl -v https://community.jivesoftware.com/api/core/v3/?foo=bar?fizz=buzz While providing the same URL to a WebView yields a callback to WebViewClient#onReceivedError(WebView webView, int error, String description, String failingUrl) with: error=-1 android webview description="net::ERR_CACHE_MISS" failingUrl="https://community.jivesoftware.com/api/core/v3/?foo=bar?fizz=buzz" Original text below: The WebViewClient class lets activities receive an onReceivedError callback when the WebView is unable to load a URL, but there is no callback for HTTP Errors, like: 401, 403, 404, 500, and so on. For instance, when a 500 error occurs no message is displayed on the WebView and there is no way we can get the received HTTP Code from WebView. android webview 404 Some workaround this issue is just horrible: http://stackoverflow.com/questions/3181843/how-can-i-check-from-android-webview-if-a-page-is-a-404-page-not-found On issue 968 the documentation was fixed for onReceivedError, but no callback was created. [1] https://code.google.com/p/android/issues/detail?id=32755 Dec 8, 2014 #1 heath.bo...@gmail.com Sorry, in my previous test I forgot to add the INTERNET permission. The behavior is even worse. We don't get onReceivedError at all. :( Dec 25, 2014 #2 stanleyc...@gmail.com I cant believe this issue is still here. Why cant specific HTTP errors be caught instead of a general catch for all HTTP errors? Jan 26, 2015 Project Member #3 mnaga...@android.com (No comment was entered for this change.) Status: Assigned Owner: mnaga...@android.com Mar 30, 2015 #4 dirtybea...@gmail.com I encountered this issue for the first time today. I'm baffled that something like this has not only excluded from the SDK, but has also repeatedly been swept under the rug and ignored so many times. Google, please put some effort towards fixing this, or at the very least, providing an official workaround until it is implemented. May 4, 2015 #5 eagleLi...@gmail.com Make sure you add following block: mWebView.setWebViewClient(new WebViewClient() { @Override public boolean shouldOverrideUrlLoading(WebView view, String url) { mWebView.loadUrl(url); return true; } @Override public void onReceivedError(Web
