Android获取CPU信息(主频,使用率)

//获得CPU最小赫兹
public static double getCpuMinFreq()
{
    double cpuMinFreq = 0;
    try
    {
        BufferedReader br = new BufferedReader(new FileReader("/sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_min_freq"));
        String text = "";
        while ((text = br.readLine()) != null)
        {
            text  = text.trim();
            if (!"".equals(text.trim()))
            {
                cpuMinFreq = Double.parseDouble(text.trim()) / 1000;
                DeviceUtil.cpuMinFreq = cpuMinFreq;
            }
            break;
        }
