原因，系统自带的和我们的库里边的类冲突了，换句话说同名类。我们删掉就可以了

<span style="color:#ff0000;"><span style="font-size:14px;">有时候，我们的工程引用了好多第三方的库，而第三方库又引用了别的jar包，那么咋找了。。。看下图找起来方便点。</span></span>
<span style="color:#ff0000;"><span style="font-size:14px;">所有的关联jar包都在这里。点开就能看到对应的包名了。。</span></span>

如上，我们看到了就是那个ksoap的问题。。
找到他，鼠标放到库后边可以看到路径的额。。
我们要做的恨简单，右键，解压缩。。然后点击去找到那2个类，删掉，然后在把解压的东西压缩。。我们的压缩软件没有jar这个后缀的，，随便了压缩成.zip的，完事自己改下后缀就好了。。。 全部弄完，工程clean下。。记得那个引用这个jar的第三方库也clean下。。最好
最好，好了。。。
