Android Question Crash in OkHttpUtils2 3.00

[Creideiki]

Hi,

I'm using OkHttpUtils2 to search for updates in background via a service.
Now I got this error message:

Fehlermeldung: java.lang.Exception: java.lang.NoClassDefFoundError: okhttp3/internal/platform/Platform
Stack-Trace:

Has anybody an idea what could have gone wrong here? The crash seems to happen in the constructor of OkHttpClient, which is called from the httputils2service create... well, a NoClassDefFoundError is quite confusing, either.
I couldn't reproduce the crash yet, and it's quite difficult to find the cause if I don't know where to search...

Perhaps another important information: The App is compiled with B4A 11.50 and the crach happend with Android 4.4.2.

Thanks.

'm using OkHttpUtils2 to search for updates in background via a service.

You are using which B4A Version?

You are running the code on which Android Version???? <--- !!!

New new okhttputils2 need Android 5+

Sorry, you were too fast for me:
The App is compiled with B4A 11.50 and the crash happend with Android 4.4.2.

New new okhttputils2 need Android 5+

Well, that would explan that. Thank you!

 

[Creideiki]

I have to dig further though...

It seems we have quite a lot of Android 4.4.2 devices out there.

I didn't find changelogs or the like for okhttputils2... so since when did it support only 5+?

What would be the best method to manage this problem?
- use an older okhttputils - is it possible to replace the one which is delivered with the ide? Where can I get it?
- use an older version of the ide? (which?)
- use another http lib - is there any, since okhttputils do what it should?

 

[DonManfred]

so since when did it support only 5+?

the newest okhttp-4.9.0 raises up to Android 5+.
If i remember correctly the changes came in dec 2021...

 

[Creideiki]

yes, there's a okhttp-3.12.12 dated 14.12.2021 in the Libraries folder; that should be from B4A 11.20. It was released on 17.05.2020 btw... perhaps it's time to cut old pigtails. I have to see.
Thank you anyway for the information!
