techknight Well-Known Member Licensed User Longtime User Apr 17, 2019 #1 So, I have a specific device running Android 4.4.4 which I cannot update or change for any reason. I am developing an App for it which uses WSS, and I cannot get WSS to work. I found this thread: https://www.b4x.com/android/forum/threads/ssl-websocket-client.88472/page-2#post-560044 But, it requires the google play services which this device does NOT have or use, it has no google services at all outside of the OS. I can install APKs to the device, etc just like any normal device. But its a Sign controller so I cant actually click buttons or anything along those lines. its just an output device only. So given that, How do I get the WSS to work? I attached the Error message screenshot I get when I run the network provider program. Any ideas?

Have you tried to use a custom trust manager that accepts all certificates? I don't think that it is will help here but it is worth a try (https://www.b4x.com/android/forum/t...rtification-path-not-found.94174/#post-596237). Upvote 0

Also is this for the Server side or the Client side? Because I have no control of the server, I am trying to integrate my app/software into an existing API/System that is in place which uses websockets. Upvote 0

Code: Copy Dim ws1 As WebSocket Dim cs As CustomTrustManager cs.InitializeAcceptAll ws1.Initialize("ws") ws1.SetCustomSSLTrustManager(cs) Depends on Net library. It will probably won't help in this case. Upvote 0
