WebViewClient onReceivedError deprecated, new version does not detect all errors

Question

In the Android SDK 23 onReceivedError(WebView view, int errorCode, String description, String failingUrl) has been deprecated and replaced with onReceived

Answer 1

Please note that the mobile device where you are testing needs to actually run Android Marshmallow (API 23). Even if you develop your app on API 23 SDK, but then run the app on Android Lollipop, you will still be getting the "old" onReceivedError, because it's the feature of the OS, not of an SDK.

Also, the "error code 109" (I guess, this is net::ERR_ADDRESS_UNREACHABLE) is not an HTTP error code, it's Chrome's error code. onReceivedHttpError is only called for the errors received from the server via HTTP. When the device is in airplane mode, it can't possibly receive a reply from a server.
