Method and device for debugging mobile application

The invention discloses a method and a device for debugging mobile application; the method comprises the steps: accessing a client terminal with to-be-debugged mobile application to the network, accessing the IP address of the client terminal on a browser of a service terminal by a user, sending a debugging command to the client terminal, carrying out program debugging for the to-be-debugged mobile application by the client terminal according to the received debugging command, and returning status parameters generated in the debugging process to the service terminal. The debugging process is carried out on the client terminal which has the environment and permissions of a script program of the to-be-debugged mobile application, so that a huge integrated development environment does not need to be installed and a simulator does not need to be used; therefore, the problems of tedious debugging process and low efficiency in the traditional debugging method can be solved.
