Abstract:To make sure that Android applications have a good responding performance,developers can use asyn-chronous ime-consuming tasks are placed in the sub-thread.This approach significantly improves the performance of the application,but it is very difficult to locate the reason when something goes wrong.This paper presents a method based on asynchronous tracking to realize the performance detection and analysis of Android application response in order to solve the problem that the Android system response performance is low and the complexity of the program execution process is increased which is caused by asynchronous programming to improve the user experience.Through the key code in the Android system s framework layer,this paper tracks the asynchronous thread execution process and constructs the critical path across the asynchronous call boundary.Finally,the main reason that affects the response performance is obtained by key path analysis and fed back to the developer.Through a number of specific test cases and the use of this method on solving the problems on OPENTHOS,results show that the desired target is achieved.
