Using a standard linux shell, I can use ps to get process information, including ram and cpu.
On the adb shell equivalent, I do not see CPU usage:
root@generic_x86:/ # ps
USER PID PPID VSIZE RSS WCHAN PC NAME
u0_a99 3129 947 1630132 156124 ffffffff b753f355 S com.example.app
How can I view CPU usage by app in the shell?
