CpuDumper

CpuDumper is a tool for third-party applications to analyze CPU usage

Feature

• Get the CPU Usage of the process, thread
• Get the Thread Stack of Java and Native (Native requires Root permission)

Usage

1. CpuDump

    //pid for file Proc/<pid>/stat and so on
    CpuDumper cpuDumper = new CpuDumper(String.valueOf(android.os.Process.myPid()));
   

2. DumpToString

    //Return the logs collected by sampler
    String log = cpuDumper.dumpToString();
   

3. OtherDumpAPI

    //Return the logs collected by sampler
    cpuDumper.dumpSystemRate(); //proc/stat
    cpuDumper.dumpAppRate();//proc/[pid]>/stat
    cpuDumper.dumpAppThreadCpu();//proc/pid/task/stat
    cpuDumper.dumpTop(5000, stream); //adb shell top cmd
    cpuDumper.dumpJavaStack();//kill -3 pid(need root)  and java api
    cpuDumper.dumpNativeStack();//debuggerd pid cmd(need root)

1. DUMPSYS CPUINFO
2. proc/cpuinfo
