many simultaneous requests you make. Too many simultaneous connections wastes resources; too few harms latency.

For asynchronous calls, [`Dispatcher`](https://square.github.io/okhttp/4.x/okhttp/okhttp3/-dispatcher/) implements policy for maximum simultaneous requests. You can set maximums per-webserver (default is 5), and overall (default is 64)....

Gradle
------

OkHttp 4’s minimum requirements are Java 8+ and Android 5+. These requirements were
[first introduced][require_android_5] with OkHttp 3.13.

Here’s what you need in `build.gradle` to target Java 8 byte code for Kotlin, Java, and Android
