b. hookOneClass yes
c. hookAllMethod
d. hookAllMethod2
e. hook_loadLibrary0
2. jni层hook
a. hook_JNIRegisterNatives
b. hook_JNI_OnLoad
3. native层hook
a. hook_dlopen
b. hook_libc_kill_exit
c. hook_system_property
d. hook_android_log_print
e. hook_call_function
f. hook_call_array
g. hook_ArtMethod_Invoke yes
h. hook_ArtInterpreterToInterpreterBridge yes
h. hook_ArtInterpreterToCompiledCodeBridge yes
4. objection的一些功能函数
a. objection_getCurrentActivity yes
b. objection_getActivities yes
5. 脱壳
a. dexdump_DefineClass
b. dexdump_DexCache yes
c. dexdump_Dex
d. dexdump_LoadMethod
6. find功能
a. find yes
b. find2
c. findClasses
7. 莫名其妙的崩溃原因
1. 添加了native的backtrace
