Hi YiXun I think gdb scripts may help you for this problem you can define a macro in .gdbinit file like this:
define hsbreak main run -Xem:interpreter $arg0 break hysl_open_shared_library continue finish disable break jni.cpp:CallStaticVoidMethod continue break interpreter.cpp:Opcode_NEW #functions whatever you like continue dis end then, you can use this macro "hs" in your gdb command to set the breakpoint and debug.
