Android studio 运行不起来，报错详情：
Error:warning: Ignoring InnerClasses attribute for an anonymous inner class
Error:associated EnclosingMethod attribute. This class was probably produced by a
Error:compiler that did not target the modern .class file format. The recommended
Error:solution is to recompile the class from source, using an up-to-date compiler
Error:and without specifying any "-target" type options. The consequence of ignoring
Error:this warning is that reflective operations on this class will incorrectly
Error:indicate that it is *not* an inner class.
解决办法如下：
一般情况下，发生这种错误多数情况下都是你导包上面出了问题。最常见的是导了不同版本的重复jar包。
那把重复的jar包删除掉，Rebuild Project.就可以解决。如果，还有其他问题，那证明你的app下的build.gradle配置就有问题。
还有，用AndroidStudio打签名包时android.keystore 的密码输入错了也会报这个。
