zygote AKInitializeOnce失败

[fettdrac]

注入zygote时发生的情况，/system分区是只读的
虽然框架发布比较久了，也希望dalao能解决下这个问题
在JNI_CreateJVM回调里调用AKInitializeOnce出错，JVM和JNIEnv参数都没问题

感觉就这两个错误看的话这两个操作好像没必要？技术有限没法对着so改。。。
su的时候也会触发JNI_CreateJVM，这时候可以正常初始化并且HOOK java方法，很奇怪

[Rprop]

CACHE_DIR = /sdcard/
不支持SD作为缓存路径

[fettdrac]

所以应该先用AKSetCacheDirectory设置CACHE_DIR吗
UPDATE：问题解决了，谢谢dalao
