How to open in webview (Jelly Bean version) bank payment service on TLSv1.2?

Question

Android

According to this discussion of ssl-protocols-with-android-webviewclient , webview versions of android 4.1 - 4.3 will not open a bank page that communicates with the client via TLSv1.2
. the share of Jelly Bean is still high - 33%, then there is an interest in supporting users on these platforms.
Has anyone dealt with the issue of TLSv1.2 compatibility with the Jelly Bean webview?

Answer 1

Jelly Bean (api 16) already has a corresponding provider

The solution is complex. It is necessary to disable fallback on SSLv3, but there is a bug, you will have to extend the SSLSocketFactory class to get rid of SSLv3 support. Then you can enable TLSv1.2.
