How to find CPU load of any Android device programmatically

Question

I want to have the same details in my android app. Anybody having any solution?

Answer 1

Use this function to get CPU details.

public static String getCPUDetails(){

    /*
     *Created By Atiar Talukdar
     * 01/01/2018
     * contact@atiar.info
     */

    ProcessBuilder processBuilder;
    String cpuDetails = "";
    String[] DATA = {"/system/bin/cat", "/proc/cpuinfo"};
    InputStream is;
    Process process ;
    byte[] bArray ;
    bArray = new byte[1024];

    try{
        processBuilder = new ProcessBuilder(DATA);

        process = processBuilder.start();

        is = process.getInputStream();

        while(is.read(bArray) != -1){
            cpuDetails = cpuDetails + new String(bArray);   //Stroing all the details in cpuDetails
        }
        is.close();

    } catch(IOException ex){
        ex.printStackTrace();
    }

    return cpuDetails;
}

Expected Output like - (I Used Emulator to generate output)
