Android Question Problem downloading web files.

[ELCHARO]

My app, use httpjob to download a file.

I compile in this platforms
android-17
android-23
android-25

Now i use OkHttp 1.01 lib
Source code of
HttpJob & HttpUtils2Service + line change to

hc.InitializeAcceptAll("hc")

Work in S7edge and S5, but not in others smartphones (olders) or ANDY & BLUESTACKS emulators.

Q1: Are a solution? or Are a minimal O.S. version to use this library?

Really don't found a solution in the community, changing the code or the library not only don't resolve the problems, sometime i never finish the compilation. And web reference send me to JAVA level (a close way for me)

Understand in which line fail, the log tell me. But not why?

Thanks.

PD: The problematic APP.
https://play.google.com/store/apps/details?id=mapadeincendios.com.ar

If a alpha version. Give error the first time ( no files).
First menu option (Actualizar)
If not make the error you can see in my country (ARGENTINA) the NASA fire logs.
I want to open to the world data, but must be more stable.

Thanks again.

hc.InitializeAcceptAll does one thing. It prevents the verification of the server certificate.

It is not required with this site as the certificate appears to be fine.
It will not help in cases where the Android device doesn't support the ciphers required by the server.
