 *  Fix: Don't lose HTTP/2 flow control bytes when incoming data races with a stream close. If this

    could use new flow control capacity before acknowledging it, causing strict HTTP/2 servers to
    fail the call.

Requirements
------------

OkHttp works on Android 5.0+ (API level 21+) and Java 8+.

OkHttp depends on [Okio][okio] for high-performance I/O and the [Kotlin standard library][kotlin]. Both are small libraries with strong backward-compatibility.

We highly recommend you keep OkHttp up-to-date. As with auto-updating web browsers, staying current
with HTTPS clients is an important defense against potential security problems. [We

 *    will be used to authenticate the client's certificate chain. Typically this is not the same
 *    set of root certificates used in server authentication. Instead it will be a small set of
 *    roots private to an organization or service.
