Android Question (solved) OkHttpUtils2 repeated download of a file fails, HttpUtils2 succeeds

While developing a port for a web site, used to download some files from it, I noticed that if I try to repeat the donwload process, I got an error from the server. Of course, I used okHTTPUtils2.

Interestingly enough, switching to the old httpUtils2, I had no problem at all with repeated downloads!

Now, I really don't want to use the old deprecated routines, but seems for now, that I can't get okHttpUtils2 to handle correctly the case. In fact, I'm not that much interested in repeated downloads, but unfortunately I have to download other files from the same site, and the result is still the same (fail).
If, however, I completely exit the app (killing it from the task manager) everything works ok again for the first time. Finally, even if clear the cache of the login webview and remove cookies, the same problem arises.

Anyone else experienced this behavior? I can provide the download source code, by private message, since it contains sensitive login information.

It failes about WHAT reason? Did you get any Error in Jobdone? Did you check the error if Job.success is false?
Post the error you got.

At first run, I get no error at all, download proceeds.

In the sample I sent, I've checked http and httpUtils2, so it's working! Have you tried using okHttp and okHttpUtils2 instead?

You need to clear the cookies. This can be done with this code:
B4X: 
If HttpUtils2Service.hc.IsInitialized Then
       Dim jo As JavaObject = HttpUtils2Service.hc
       jo = jo.GetFieldJO("client").RunMethod("cookieJar", Null)
       Dim r As Reflector
       r.Target = jo
       Dim CookieManager As JavaObject = r.GetField("cookieHandler")
       CookieManager.RunMethodJO("getCookieStore", Null).RunMethod("removeAll", Null)
   End If
You need to remove OkHttpUtils2 library and replace it with the two code modules. Make HttpUtils2Service.hc a public variable.

thank you Erel! This means however that every time this lib is updated I have to manually repeat the process. Any chance that clearing cookies can be set using a method?

Using the above code indeed solved the problem. Once again, thank you very much, Erel!
