Android App issue with Websocket

[sebastienl]

Hi,

I'm trying to use the Java SDK on Android 5 and I'm encountering an issue with the WebSocket. I've successfully created and tested the App on the Android simulator but when I test the same APK on a Phone it's not working. The communication with the TWX server failed. End of the log of the Android App running on the Phone :

Did someone already see this error and knows how to fix it ?

Thanks a lot,

Hello,

I had a similar error but not in Android but in an OSGi environment. The issue was with some missing dependencies of Netty client. Can you post the complete log ?

Hi,

Thanks for your help but I had a chat with a guy from TWX R&D and he told me that this issue is because Java SDK is not supported on Android. They are working on Android SDK and it will be delivered in coming months. So for now I moved my code to REST API. This is for a prototype so REST API is ok.

Regards,
