生成签名的 apk 时发生错误。生成可调试的 apk 时工作正常。安卓工作室 2.3 版。我在 gradle 文件中添加了以下代码，但它不起作用。

Error:trouble processing "java/io/BufferedInputStream.class":
Error:Ill-advised or mistaken usage of a core class (java.* or javax.*)
Error:when not building a core library.
Error:This is often due to inadvertently including a core library file
Error:in your application's project, when using an IDE (such as
Error:Eclipse). If you are sure you're not intentionally defining a
Error:core class, then this is the most likely explanation of what's
going on.
Error:However, you might actually be trying to define a class in a core
Error:namespace, the source of which you may have taken, for example,
Error :from a non-Android virtual machine project. This will most
Error:assuredly not work. At a minimum, it jeopardizes the
Error:compatibility of your app with future versions of the platform.
Error:It is also often of questionable legality.
Error:If you really intend to build a core library -- which is only
Error:appropriate as part of creating a full virtual machine
Error:distribution, as opposed to compiling an application -- then use
Error:the "--core-library" option to suppress this error message.
Error:If you go ahead and use "--core-library" but are in fact
Error:building an application, then be forewarned that your application
Error:will still fail to build or run, at some point. Please be
Error:prepared for angry customers who find, for example, that your
Error:application ceases to function once they upgrade their operating
Error:system. You will be to blame for this problem.
Error:If you are legitimately using some code that happens to be in a
Error:core package, then the easiest safe alternative you have is to
Error:repackage that code. That is, move the classes in question into
Error:your own package namespace. This means that they will never be in
Error:conflict with core system classes. JarJar is a tool that may help
Error:you in this endeavor. If you find that you cannot do this, then
Error:that is an indication that the path you are on will ultimately
Error:lead to pain, suffering, grief, and lamentation.
Error:1 error; aborting
Error:Execution failed for task ':app:transformClassesWithDexForRelease'.

这是 app.gradle 文件。Multidex 启用，缩小禁用。我从 gradle 文件中删除了一些未使用的库。可复制的 apk 生成没有任何问题。
