    trouble processing "java/text/FieldPosition.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.

    原因一般是有重复的jar包(但是文件名不一样没有被发现),remove所有buildpath,然后重新导入jar。

    比如:主项目含有Android 4.4(android.jar),Android Dependencies又引入了一个android.jar。

    项目的根目录下的3个引用相关的组

    Android 4.4:里面一般是android.jar,是一个Android项目必备

    Android Dependencies:里面一般是引用其它项目产生的lib,操作为右键项目 ——properities——Android——在 is library中加入项目

    Referenced Libraries:里面是libs文件夹下的jar右键——Add to path的结果

     其它不相关的组都remove掉,比如Android Private

    Done!
