Hello! This is a job I did 2 years ago so I hope I can answer you. I'm asking you some things to better understand the problem. Did you find the endpoints yet? Did you follow my thesis or did you create your own server? (you can find the pdf thesis in the master)
I have a my own opc ua server. It's security is Sign&Encrypt and Basic256SHA256. I connect it with username and password. But when i click button connect, it show textview: "connecting failed". No certificate file was created on my server in other to I accept.

Excuse me for asking again, but I need it to figure out what the problem is. Were you able to find the endpoints? I'm asking because maybe the problem is before the connection.
How to know I found the endpoints? I modified the code with my endpoint, my security and my value on server to read. After that, I run project, but when I click connect button, it show text view "connection fail". I find out certificate file on my sẻver to accept, but it not created.

In DISCOVER ENDPOINT section in MainActivity I wrote these lines at the end of the section:
System.out.println("Security Level " + endpoint.getSecurityPolicyUri());
System.out.println("Security Mode " + endpoint.getSecurityMode());
On android studio you can see what is written so you can see if you can find the endpoints and also the level and mode security.
I think my problem is variable my client initializer is redundant and i couldn't fix it [image: image.png]

I'm really sorry, but I can't download the project and check it out at the moment. Were you able to figure anything out in the meantime?

it dont display Security Level and Security Mode in android studio
If you don't want to use System.out.println you can use:

Ok now with the logcat you can better understand the problem. Anyway, yes, the first problem to solve is the SLF4J libraries. I don't know if you have already read it but in my thesis I write in detail all the steps to do. https://github.com/lucazanrosso/OPCUAClient/blob/master/OPCUAClient%20guide.pdf
Anyway as I told you I'm sorry I can't help you directly with Android Studio but right now I'm abroad for many months for study and I don't have the PC with Android Studio installed anymore.
I have read your thesis carefully. I use your project on your github and just modify info of my server

Excuse me. I tried to read the Log but it is really long and difficult to understand. By chance can you find the source of the problem more specifically?
Hi guy, I couldn''t connect my opc ua server via user name and password. Can you help me?. Thanks
