Summary

This app focuses on capturing systrace data from handset directly, along with other system information, such as vmstat, meminfo, ps, top info. The below picture depicts the entire processing flow:

First of all, when user touch floating icon to ready for capturing systrace, the app starts off several new threads to get systrace, vmstat, meminfo information synchronously; and then, it starts off other thread to catch ps and top information after finished all the work mentioned as above. While all the threads run out, the floating icon change its status from freezing to original to mean that all the processes finished and the information have been attained.

Code Structure

The code structure seems like MVP pattern, in which TaskManager acts like Presenter: it is the overall controller that creates and connects views and threads. All the threads in running in the mWorkThreadPool, mCommandWorkQueue is a queue of Runnables for the mWorkThreadPool.
