Question

Why java.lang.management isn’t available in android? (At least i know that)

I need the use of “getCurrentThreadCpuTime” from “ThreadMXBean” class but I need ManagementFactory in order to retrieve it.

Is there an alternative to that class in android?

I need the cpu time spent by my thread.

Thanks in advance

Android run on linux, so you can get the thread info from file /proc/$pid/stat.

You can read and analyse file /proc/$pid/stat to get the info you want.

public void getTotalMemory() {
String path = "/proc/$pid/stat";
String info="";
try {
    FileReader fr = new FileReader(path);
    BufferedReader localBufferedReader = new BufferedReader(fr, 8192);
    while ((info = localBufferedReader.readLine()) != null) {
        //analyse 
        System.out.println("ThreadInfo:" + info);
    }
    // close...
    } catch (IOException e) {
    }
}
