onReceivedSslError 已修复但仍显示错误

Question

I got an "onReceivedSslError" error in my Play Console account as in the screenshot.

I have handled the onReceivedSslError in all WebViewClients and show the required warning message. Then I sent the version to the market and got approval. The version has been released, but it still says this error is in this version, as seen above, under the version. Why is it showing up even though I applied it to all WebViewClients?

@Override
        public void onReceivedSslError(WebView view, SslErrorHandler handler, SslError error) {
            Utilities.showAlertDialog(getActivity(),
                    "SSL Certificate Error", Utilities.getSslErrorMessage(error.getPrimaryError()),
                    getString(R.string.common_continue),
                    getString(R.string.order_detail_product_cancel),
                    () -> handler.proceed(),
                    () -> {
                        handler.cancel();
                    });
        }


public static String getSslErrorMessage(int primaryErrorCode){
    String message = "SSL Certificate error.";
    switch (primaryErrorCode) {
        case SslError.SSL_UNTRUSTED:
            message = "The certificate authority is not trusted.";
            break;
        case SslError.SSL_EXPIRED:
            message = "The certificate has expired.";
            break;
        case SslError.SSL_IDMISMATCH:
            message = "The certificate Hostname mismatch.";
            break;
        case SslError.SSL_NOTYETVALID:
            message = "The certificate is not yet valid.";
            break;
    }
    message += " Do you want to continue anyway?";
    return message;
}

Edit: The error turned yellow on the Play Console after a while, then it stopped coming at all. And I got an email that the error persists. I don't understand why this is so.

I'm on version 75 right now.

Answer 1

Although you have handled the onReceivedSslError in all WebViewClient s and shown the required warning message, it is possible that there are still some code paths that are not handled properly.

If you reviewed your code again and made sure that you are handling all possible scenarios in the onReceivedSslError method (including showing the warning message properly), make sure that you disabled SSL/TLS certificate validation.

Could you please post the code snippet in the screenshot, in textual form, to be examined in more detail?

UPDATE (after OP posted code snippet):

While it seems you have correctly implemented the SSL error handling logic in your WebViewClients, it seems that your problem lies in the way your Utilities.showAlertDialog(...) is handling proceed() vs. cancel() .

In my working code (also deployed to Google Play, without an issue), my dialog allows clicking "proceed" or "cancel" for all errors, except for SSL_IDMISMATCH which is always handled as "proceed":

        if (error.getPrimaryError() != SslError.SSL_IDMISMATCH) {
            final AlertDialog dialog = builder.create();
            dialog.show();
        }
        else {
            handler.proceed();
        }

Does this help?

UPDATE II (after OP responded that the above did not help):

I am posting here the complete onReceivedSslError(...) that works on Google Play:

@Override
public void onReceivedSslError (WebView view, final SslErrorHandler handler, SslError error) {        
    final AlertDialog.Builder builder = new AlertDialog.Builder(this.mMeWebView.getContext());
    String message;
    switch (error.getPrimaryError()) {
        case SslError.SSL_EXPIRED:
            message = "The certificate has expired.";
            break;
        case SslError.SSL_IDMISMATCH:
            message = "The certificate Hostname mismatch.";
            break;
        case SslError.SSL_NOTYETVALID:
            message = "The certificate is not yet valid.";
            break;
        case SslError.SSL_UNTRUSTED:
            message = "The certificate authority is not trusted.";
            break;
        default:
            message = "Unknown SSL error.";
            break;
    }
    message += " Do you want to continue anyway?";

    builder.setTitle("SSL Certificate Error");
    builder.setMessage(message);
    builder.setPositiveButton("continue", new DialogInterface.OnClickListener() {
        @Override
        public void onClick(DialogInterface dialog, int which) {
            handler.proceed();
        }
    });
    builder.setNegativeButton("cancel", new DialogInterface.OnClickListener() {
        @Override
        public void onClick(DialogInterface dialog, int which) {
            handler.cancel();
        }
    });
    if (error.getPrimaryError() != SslError.SSL_IDMISMATCH) {
        final AlertDialog dialog = builder.create();
        dialog.show();
    }
    else {
        handler.proceed();
    }
}

It is not pretty as yours (Java8+ guidelines) but it works.
