android - 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 onReceivedError(WebView view, WebResourceRequest request, WebResourceError error). However if I put my phone in Airplane mode and load an url on my WebView, only the deprecated version of the method is called.

onReceivedHttpError (WebView view, WebResourceRequest request, WebResourceResponse errorResponse) is also not useful, as it only detects errors higher than 500, and I am getting a 109 status code.

Is there a non-deprecated way of detecting that my WebView failed to load?

Answer 1

You could also do following:

@SuppressWarnings("deprecation")
@Override
public void onReceivedError(WebView view, int errorCode, String description, String failingUrl) {
    // Handle the error
}

@TargetApi(android.os.Build.VERSION_CODES.M)
@Override
public void onReceivedError(WebView view, WebResourceRequest req, WebResourceError rerr) {
    // Redirect to deprecated method, so you can use it in all SDK versions
    onReceivedError(view, rerr.getErrorCode(), rerr.getDescription().toString(), req.getUrl().toString());
}

Make sure you import android.annotation.TargetApi

Happy coding!
