Method and system for simultaneously detecting and comparing performance among multiple applications under Android platform

The invention discloses a method and system for simultaneously detecting and comparing performance among multiple applications under Android platform. The method includes such steps as creating start-up thread starting up simulation operation tool, simulating all apps to be tested to the foreground by simulation operation tool, setting up the probability of each app being adjusted to be the same,and keeping the total operation time of foreground to be the same, testing the performance of the foreground by simulation operation tool, and setting up the operation time of the foreground to be thesame. At least one statistic thread is create, and that at least one statistic thread respectively periodically counts the correspond performance index data of the Android platform when each app is operated in simulation; the at least one statistic thread counts the corresponding performance index data of the Android platform when each app is operated in simulation; when the preset test durationis reached, all threads are
