华为运行APK时的ART空指针间接引用报错问题

1. 问题情况

在此前已经正常运行过的项目，重新修改了配置信息（gradle和一些业务环境信息如域名等）后重新运行时，运行后若干秒后会发生闪退并输出了以下的错误信息。并且该错误在华为系统上产生，但在三星、魅族的手机上并不会闪退也没有输出类似的错误信息。

根据以上的错误信息，可以知道是在ART的处理中出现了Cause: null pointer dereference这个错误，该错查阅一下资料可以知道空指针间接引用的问题。

由于能找到的所有的华为系统手机运行时都有这个问题，但是其它品牌的手机确实也不会有问题，并且问题的产生是在ART的so库，初步估计跟应用的业务是没有关系的。但是接下来诡异的情况就来了。

在偶然的情况下，发现应用并不会闪退，再三测试和验证后发现，如果连接着USB线，应用启动后就会出现闪退的情况；如果不连接着USB线，就不会发生闪退。当时就一脸懵逼？？？这是什么操作？
但是再三测试后确实是如此的。这就更加证明跟应用业务逻辑是没有关系的，但是问题是出在哪无法确认。这时考虑是否是AS的影响呢？因为AS已经运行了很久并且是反复切换了大量的项目不确定是否与AS的一些运行状态或缓存有关，重启了AS后，该问题不再出现。

暂时还不知道原因是什么，先记录一下以供后续参考。
