Android在eclipse中添加外部自定义库时出错

为什么在运行应用程序时会出现以下错误？生成应用程序时没有错误

trouble processing "javax/security/cert/CertificateException.class":

Ill-advised or mistaken usage of a core class (java.* or javax.*)
when not building a core library.

This is often due to inadvertently including a core library file
in your application's project, when using an IDE (such as
Eclipse). If you are sure you're not intentionally defining a
core class, then this is the most likely explanation of what's
going on.

However, you might actually be trying to define a class in a core
namespace, the source of which you may have taken, for example,
from a non-Android virtual machine project. This will most
assuredly not work. At a minimum, it jeopardizes the
compatibility of your app with future versions of the platform.
It is also often of questionable legality.

If you really intend to build a core library -- which is only
appropriate as part of creating a full virtual machine
distribution, as opposed to compiling an application -- then use
the "--core-library" option to suppress this error message.

If you go ahead and use "--core-library" but are in fact
building an application, then be forewarned that your application
will still fail to build or run, at some point. Please be
prepared for angry customers who find, for example, that your
application ceases to function once they upgrade their operating
system. You will be to blame for this problem.

If you are legitimately using some code that happens to be in a
core package, then the easiest safe alternative you have is to
repackage that code. That is, move the classes in question into
your own package namespace. This means that they will never be in
conflict with core system classes. JarJar is a tool that may help
you in this endeavor. If you find that you cannot do this, then
that is an indication that the path you are on will ultimately
lead to pain, suffering, grief, and lamentation.

您正试图将

java

或

javax

类添加到项目中。这通常不受支持

在此特定情况下，您正在尝试添加。这是毫无意义的，因为Android中的副本将胜过这个库中的任何副本

---

您尝试使用的库不是为在Android上使用而设计的（在普通Java上可能会受到严重怀疑），它需要修改。使用另一个库可能会更好。

是的，我在库路径中错误地添加了“android.jar”，我删除了它，效果很好。谢谢。@Alias:好的，就这样。通常，我看到的错误来自于android.accessibility中的一个重复类（编译器遇到的第一件按字母顺序排列的事情）。这就是为什么我没有考虑你作为候选人的具体问题。不过，很高兴你能成功！隐马尔可夫模型。。。我需要了解更多。。。通常你的支持是非常棒的。。。谢谢。
