如何访问Android 7.0或更高版本的Nougat中的进程？

Question

I tried to access the process information through the '/ proc' file. But it didn't work. I wonder to know how Greenify implement this function. Thanks in advance!

Unfortunately you can no longer do this in Android 7.0. With Android 7.0, Google has significantly restricted access to /proc.

This limitation/feature has already been reported to Google: https://code.google.com/p/android/issues/detail?id=205565

An alternative would be to use UsageStatsManager.
