Android App - webview SSL Error - google play

Question

When I submit a version to Google Play, it is constantly rejected due to SSL and the incoming mail says "For more information on how to address WebView SSL Error Handler alerts, please see this Google Help Center article." I'm getting the message. I tried many methods. I removed the onReceivedSslError() method and it didn't work. I used cancel() method instead of proceed() and it still didn't work.
