[android-developers] Re: CPU usage stats
As a developer I would say it is VERY important to measure how efficient your implementation (code) is. CPU usage (which can sucks the battery) and memory usage etc are very important issues specially for developers.

I know it's not the same using an actual phone than an emulator, but on the emulator there is an option I believe that shows CPU status... -Moto On Oct 6, 9:58 am, askPrins askpr...@gmail.com wrote: As a developer I would say it is VERY important to measure how efficient your implementation (code) is.

Hi, Maybe you could have a look at com.android.server.ProcessStats :) Cheng On 6 sep, 17:33, Andy a...@fendley.com wrote: Hi everyone, Does anyone know of a direct api that allows access to CPU usage statistics for different applications/tasks running inside android? All I can find is data available by accessing a file /proc/stat but this seems a little cumbersome. ActivityManager holds data about processes/tasks etc but no CPU usage stats.

Thats great thanks but I want to access these stats from inside a running Activity...just wondered if there was a direct api to use.

Re: [android-developers] Re: CPU usage stats
Not in the SDK. I suppose because most uses of this is by developers who can simply use adb or ddms. -- You received this message because you are subscribed to the Google Groups Android Developers group.

Re: [android-developers] Re: CPU usage stats
There isn't an SDK API for this. Also note that /proc is not part of the SDK -- you can't count on the contents of /proc remaining compatible in future versions.
