[Question] is hook the func really works?

[eebssk1]

In android_os_properties.cpp JNI source,the native java method first check if the prop exists in prop pool, then create a prop object and pass to the __system_prop_read_callback func.if it can't find the prop then it simple return.So I want to know why you hook this func.In my module I hook __system_prop_find and create a fake prop instead. Waiting for your reply,thx... https://github.com/eebssk1/riru_MPH/blob/master/module/src/main/cpp/main.cpp
