모바일 앱에서 frida timeout error 해결 방법

최근에는 주로 모바일 앱 후킹시 frida 를 이용하고 있는데, 안드로이드 느린 앱을 후킹하려고 하다 보면 가끔 아래처럼 

타임아웃 메시지가 나오며 죽어버리는 경우가 있다.

이 경우 해결방법.

hyunmini:02.dbi $ python dbi.py Traceback (most recent call last):   File "dbi.py", line 73, in <module>     main(target_process)   File "dbi.py", line 54, in main     pid = frida.get_usb_device().spawn([target_process])   File "/Library/Python/2.7/site-packages/frida/core.py", line 85, in spawn     return self._impl.spawn(argv) frida.TimedOutError: unexpectedly timed out while waiting for app to launch

...

pid = frida.get_usb_device().spawn([target_process])

...

앱 실행하는 위 코드에 timeout 인자값을 주면 됨(;;)

...

pid = frida.get_usb_device(timeout=10).spawn([target_process])

...

이제 잘 된다.
