HTTP/2协议不能与okhttp一起使用

我正在使用带有okhttp 2.4.0的Retrofit 1.9.到目前为止,我们在服务器端禁用了SPDY协议(我通过此检查).服务器端的启用协议是HTTP/2(我通过此检查).

所以我认为okhttp将尝试使用HTTP/2(最新的一个协议)进行api调用,但它在Android设备4.2.2 samsung S4上使用HTTP/1.1 -

D/Retrofit : OkHttp-Selected-Protocol: http/1.1

有人告诉我Android设备直到5.0 才支持SPDY(我没有任何证据),因此该设备从未尝试过使用SPDY连接.但我确信我们的服务器根本没有使用SPDY我自己使用上面的链接检查了它.

并且okhttp开始支持HTTP/2,因为它是2.3.0版本,请参见此处.

如果我在上面的Android 5.0中使用相同的东西,我在生产应用程序上获得了相同配置(okhttp 2.4.0和Retrofit 1.9)的异常 -
