    changing the cpu frequency

    hi guys im trying to develop an android application in which im tryin to change the scaling_governor to userspace so that i can set the cpu frequency but i dont know how to gain root user permission programatically in order to change the scaling_governor. is there any way to change the scaling_governor and to set user specified cpu frequency??

    String[] args = {"/system/bin/echo userspace >", "/sys/devices/system/cpu/cpu0/cpufreq/scaling_governor"};
    ProcessBuilder cmd1;
    cmd1 = new ProcessBuilder(args);
    Process process = cmd1.start();

    it is not changing the scaling_governor what is wrong in this??
