我尝试构建一个发布版apk时，出现了以下错误。
在build.gradle文件中，我有这样一段代码:
dependencies { compile "com.android.support:support-v4:23.0.0" }
如果我将其改为以下代码，仍然会收到同样的错误提示：
"com.android.support:support-v13:23.0.0"
当错误提示显示：“您可能需要更新库版本。”指的是哪个库？如何更新它？
错误信息所引用的文档提到：
"If you're developing for Android and ProGuard complains that it can't find a method that is only available in a recent version of the Android run-time, you should change the build target in your project.properties file or build.gradle file to that recent version. You can still specify a different minSdkVersion and a different targetSdkVersion in your AndroidManifest.xml file."
这是我的build.gradle文件，其中API版本号为最新的23。那么我该如何解决这个问题呢？

You probably need to update the library versions.
