Android Question okHttp - javax.net.ssl.SSLProtocolException SHA-256

[MarcoRome]

Hi all. Time ago i write time ago one library Paypal credit card, now seem that this library have a few problems with SSL, when i call:

https://api.sandbox.paypal.com/v1/oauth2/token","grant_type=client_credentials")

find message i have this error:

javax.net.ssl.SSLPeerUnverifiedException: No peer certificate

After i change this line code:

Change hc.Initialize in HttpUtils2Service to hc.InitializeAcceptAll

as suggestion Erel HERE

Now i have this error:

javax.net.ssl.SSLHandshakeException: javax.net.ssl.SSLProtocolException:
SSL handshake aborted: ssl=0x7a11ad08: Failure in SSL library, usually a protocol error
error:14077410:SSL routines:SSL23_GET_SERVER_HELLO:sslv3 alert handshake failure (external/openssl/ssl/s23_clnt.c:741 0x74686718:0x00000000)

Any idea ?
Thank you
Marco

You can install a provider with JavaObject. See the attached project.

With this code seem that work.
But now i have this message:

{"error":"invalid_client","error_description":"Client credentials are missing"}

Seem that dont see Credentials, as if lost this ( User and Password ).
The code is:

job1.Username = client_id_app1
job1.Password = secret_app1
job1.PostString("https://api.sandbox.paypal.com/v1/oauth2/token","grant_type=client_credentials")
job1.GetRequest.SetHeader("Content-Type", "application/json")
job1.GetRequest.SetHeader("Accept-Language", "en_US")

This work in Android 5.0 ( without add ProviderInstaller ) but give me error up with Android 4.4.
I think we're almost, but something is missing, as if he lost the credentials.

Note that you should call GetRequest.SetContentType instead of SetHeader. It is probably not related to the credentials but your current code will not set the content type header.

.....
job1.PostString("https://api.sandbox.paypal.com/v1/oauth2/token","grant_type=client_credentials")
job1.GetRequest.SetContentType("application/json")
'job1.GetRequest.SetHeader("Accept-Language", "en_US")

I have this error ( job.ErrorMessage ):

Unsupported Media Type

 

[Erel]

You haven't set the Accept header.

 

[MarcoRome]

You haven't set the Accept header.

Some error:

job1.PostString("https://api.sandbox.paypal.com/v1/oauth2/token","grant_type=client_credentials")
job1.GetRequest.SetHeader("Accept-Language", "en_US")
job1.GetRequest.SetHeader("Accept","application/json")
job1.GetRequest.SetContentType("application/json")

The problem is related to the provider as it works with Android 5+. You need to find a Java solution that works with their API. I can then help you port it.
