Android Question OkHttp and https

[cdsnl]

Hi,
Using B4A 11.50.

When I use OkHttp and OkHttpUtils2 to do a poststring to an http it works fine.
When I do the same on https I get the error:
ResponseError. Reason: java.io.IOException: Android internal error, Response:
java.io.IOException: Android internal error

When I remove OkHttoUtils2 from my project and add the files HttpJob.bas and HttpUtils2Service.bas then both http and https are not working any more, and will give the same error.

If I change the following code
hc.Initialize("hc")
into
hc.InitializeAcceptAll("hc")
I get the same errors.

I put in a Log line in Service_Create to make sure it uses the correct code.

Note: the http and https uses the same software. The http is a server on the LAN, the https is a server on the internet.

Please advice

Thank you.
Andre

DELETE the old and deprecated(!!) httputils module and Service.

Switch to okhttputils2 and use this.
If you run into a problem;. Create a new thread with enough details (post a project showing the problem). Also post the FULL error/stacktrace. There must be one!

Thanks manfred,
Maybe I understand it not correct. I am using OkHttp and OkHttpUtils2.
The two .bas files come from the https://www.b4x.com/android/forum/threads/b4x-okhttputils2-ihttputils2-httputils2-source-code.82632/

Or do you mean to delete the files http.* and HttpUtils2.* from the internal library directory?

Thanks

The two .bas files come from the

delete them. Use the Library instead. Only okhttputils2-Library

 

[cdsnl]

Still the same error.
What did I do:
I have check OkHttp and OkHttpUtils2 in the library manager
I have removed the two .bas files from the project which had add from the early mentioned ticket.
And I have deleted 4 files http.* and HttpUtils2.* files from the Internal Library directory.

Hi Manfred,
Sorry for the delay, I was out for a couple of days.
But I found what the issue was when I was making a sample project.

When I do this.
j.PostString("https://sub_domain.domain.com/api","ABC")
It goes wrong and I get the error
ResponseError. Reason: java.io.IOException: Android internal error, Response:
java.io.IOException: Android internal error

When I do this
j.PostString("https://subdomain.domain.com/api","ABC")
It goes OK.

It seems that underscores in the url are not handle well. In other applications, like postman, it is no problem to use underscores.

Best regards
Andre

Underscore characters are not permitted in domain names in accordance with RFC 1035, which only allows letters, digits and hyphens. As such, you cannot register a domain name with an underscore character.

that´s probably the issue. Use subdomainnames without underscore.

It seems that underscores in the url are not handle well. In other applications, like postman, it is no problem to use underscores.

Please note that this has nothing to do with the library used (nor B4A). This is an issue with Android not accepting underscores in sub-domains. Blame it on the people not following standards (those that allowed underscores to be used). This may be fixed in future Android versions.

Crash on Android 10 with underscore in subdomain · Issue #5840 · square/okhttp

Crash on OkHttp 3.12.9 and 3.12.10 when a URL subdomain contains underscores. Reproducible on API 29 (Android 10) emulator but not API 28 (Android 9). On OkHttp 3.12.8 it errors but does not crash....
