         我各种谷歌百度,都说是编译环境不一致的问题,但请仔细看version(000000),并没有说是jdk版本的问题,提示的错误很明显是java的class损坏,无法识别,最后纠结了将近两个礼拜,才知道原来这个jar包,先前的经理为了防止别人篡改,这个类本身就不是java的class,只是取了一个名字而已,导致android 在真机运行时,无法将第三方的jar包打到apk中,记录一下,这是一个很大的坑.

    注意: -==============================================分割线==========================================================

    你使用别人给的jar的时候,大多数只会提示bad class file,但并不会提示你哪个class损坏或者有问题的,所以我有一个比较绕的方法就是使用混淆android工程代码,当混淆出错的时候,就会具体指向哪个class无法进行混淆,这样你就知道哪个jar包出错了,如下图:
