[android-developers] Re: Obtaining/calculating process CPU usage.
Hello Dianne,
Which functionality may break in future releases?
Is it executing the command using runtime?
"String cmd = "top -n 1";
process = runtime.exec(cmd);"
or something else in this code segment?
thanks,
Sachin

This is very likely to break in future platform updates.

I though I sent it once, but Use out put of top linux command with java Runtime. On May 4, 4:02 pm, Donald_W wrote: > Hello, > > How can I get/calculate current process CPU usage?

[android-developers] Re: Obtaining/calculating process CPU usage.
You can use output of the top command, for your process
Here is what I did:
Runtime runtime = Runtime.getRuntime();
Process process;
String res = "-0-";
try {
String cmd = "top -n 1";
process = runtime.exec(cmd);
InputStream is = process.getInputStream();
InputStreamReader isr = new InputStreamReader(is);
BufferedReader br = new BufferedReader(isr);
String line ;
while ((line = br.readLine()) != null) {
String segs[] = line.trim().split("[ ]+");
if (segs[0].equalsIgnoreCase([Your Process
ID])) {
res = segs[1];
break;
}
}
} catch (Exception e) {
e.fillInStackTrace();
Log.e("Process Manager", "Unable to execute top
command");
}

Well I thought rather of any calculations using some process data. Anyway thanks for help. BR, Tomek On May 5, 9:20 am, Dianne Hackborn wrote: > There is no supported API for this.

[android-developers] Re: Obtaining/calculating process CPU usage.
There is no supported API for this. I am not helping people find and use unsupported APIs, and then having to deal with their apps breaking when we update the platform.

So is there any possibility to calculate CPU usage?
