Android Question SSL handshake aborte

[Walter Adriano da Silva]

On devices with android 6+ my app works normally, but when I try run it on a device with Android 4.4, I got this:

javax.net.ssl.SSLHandshakeException: javax.net.ssl.SSLProtocolException: SSL handshake aborted: ssl=0x62b2fe10: Failure in SSL library, usually a protocol error

I'm using OkHttp with HttpUtils2, and for tests, the app uses "hc.InitializeAcceptAll("hc")"

Could anyone help me with this?

Thanks

What are you connecting to? InitializeAcceptAll will help when the certificate is not signed by a recognized authority. It will not help if the encryption protocol is not supported.

 

[Walter Adriano da Silva]

I'm connecting to my own server, an extranet service, then I use InitializeAcceptAll, once the certificate for this server is not signed.

You need to check your server configuration. The problem might be in the supported ciphers.

 

[Walter Adriano da Silva]

Ok. I'll check this. But, why this problem don't occur with Android 6.0?

 

[Erel]

The set of supported ciphers changes between different versions.

 

[Walter Adriano da Silva]

The HttpUtils2 module supports TLSv1.2? My server is configured with it, then I think my problem involve this.

 

[Walter Adriano da Silva]

I tried others settings on the server, but I found others errors, like this. As viewed in link, is it possible implement that code to specify protocol?

 

[Erel]

Have you tried it with OkHttpUtils2?

 

[Walter Adriano da Silva]

Yes

 

[Erel]

It is not possible to change the enabled protocols. Did you also try it with HttpClient?

 

[Walter Adriano da Silva]

I migrated from HttpClient some time ago, for problems in Android 6, then I don't thought to test with HttpClient.

 

[Erel]

If it works with HttpClient then you can use HttpClient. You just need to make sure to compile with android.jar from v5 instead of v6.

 

[Walter Adriano da Silva]

How can I set TLS version in OkHTTP?

 

[Erel]

It is not possible to set it.

I think that is same problem that THIS. Work without problem with Android Lollipop ( 5 or > ) but with < have this problem
