Does Android use OkHttp internally?

Question

This is a stack trace I get when running an Android app I recently inherited. We're not using OkHttp as an explicitly dependency, and the com.android.okhttp in the trace makes me think the AOSP is using OkHttp now internally?

Answer 1

Yes, Android as of Android 4.4 is using OkHttp for its internal HttpUrlConnection implementation.
