release包在visitField方法中object值不为空，在返回时变量被置空，在接下来的visitLdcInsn和visitFieldInsn方法中不会执行这个变量的回调，编译出包后变量初始为空

静态变量当有初始值时，stringfog会在StringFogClassVisitor的visitField中置空，在的visitCode中不会去对mStaticFields中的存储的value不为空的变量赋值，在接下来的visitLdcInsn和visitFieldInsn方法中不会对变量赋值，导致编译出的apk中的静态变量初始值为空

目前打印了项目中所以的静态变量，发现有3处出现这个问题，腾讯的OpenSDK中有2处，我的解决方案是在clinit的visitCode中对mStaticFields中的存储的value不为空的变量加密赋值
