这是一个堆栈跟踪运行Android应用程序最近，我继承时，我得到。我们不使用okhttp为显式依赖，并在跟踪的com.android.okhttp使我想起了AOSP使用okhttp现在在内部？

  java.lang.Throwable中：显式的终止方法关闭不叫
                        Ë在dalvik.system.CloseGuard.open（CloseGuard.java:184）
                        Ë在com.android.org.conscrypt.OpenSSLSocketImpl.startHandshake（OpenSSLSocketImpl.java:278）
                        Ë在com.android.okhttp.Connection.upgradeToTls（Connection.java:146）
                        Ë在com.android.okhttp.Connection.connect（Connection.java:107）
                        Ë在com.android.okhttp.internal.http.HttpEngine.connect（HttpEngine.java:294）
                        Ë在com.android.okhttp.internal.http.HttpEngine.sendSocketRequest（HttpEngine.java:255）
                        Ë在com.android.okhttp.internal.http.HttpEngine.sendRequest（HttpEngine.java:206）
                        Ë在com.android.okhttp.internal.http.HttpURLConnectionImpl.execute（HttpURLConnectionImpl.java:345）
                        Ë在com.android.okhttp.internal.http.HttpURLConnectionImpl.getResponse（HttpURLConnectionImpl.java:296）
                        吃com.android.okhttp.internal.http.HttpURLConnectionImpl.getHeaderField(HttpURLConnectionImpl.java:143)
                        Ë在java.net.URLConnection.getHeaderFieldInt（URLConnection.java:544）
                        Ë在java.net.URLConnection.getContentLength（URLConnection.java:316）
                        吃com.android.okhttp.internal.http.HttpsURLConnectionImpl.getContentLength(HttpsURLConnectionImpl.java:18

解决方案

是Android的为Android 4.4系统的，是用OkHttp其内部的HttpURLConnection 的实施。

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

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