通過代碼實現獲取手機CPU信息

要獲取手機CPU的基本信息可分爲幾類：CPU最高頻率、CPU最低頻率、CPU當前頻率、CPU型號等。

以下是獲取最高頻率信息的代碼：

        public static String getMaxCpuFreq() {
                String result = "";
                ProcessBuilder cmd;
                try {
                        String[] args = { "/system/bin/cat",
                                        "/sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_max_freq" };
                        cmd = new ProcessBuilder(args);
                        Process process = cmd.start();
                        InputStream in = process.getInputStream();
                        byte[] re = new byte[24];
                        while (in.read(re) != -1) {
                                result = result + new String(re);
                        }
                        in.close();
                } catch (IOException ex) {
                        ex.printStackTrace();
                        result = "N/A";
                }
                return result.trim();
        }

獲取最低頻率的代碼

        public static String getMinCpuFreq() {
                String result = "";
                ProcessBuilder cmd;
                try {
                        String[] args = { "/system/bin/cat",
                                        "/sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_min_freq" };
                        cmd = new ProcessBuilder(args);
                        Process process = cmd.start();
                        InputStream in = process.getInputStream();
                        byte[] re = new byte[24];
                        while (in.read(re) != -1) {
                                result = result + new String(re);
                        }
                        in.close();
                } catch (IOException ex) {
                        ex.printStackTrace();
                        result = "N/A";
                }
                return result.trim();
        }

獲取當前頻率：

        public static String getMinCpuFreq() {
                String result = "";
                ProcessBuilder cmd;
                try {
                        String[] args = { "/system/bin/cat",
                                        "/sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_min_freq" };
                        cmd = new ProcessBuilder(args);
                        Process process = cmd.start();
                        InputStream in = process.getInputStream();
                        byte[] re = new byte[24];
                        while (in.read(re) != -1) {
                                result = result + new String(re);
                        }
                        in.close();
                } catch (IOException ex) {
                        ex.printStackTrace();
                        result = "N/A";
                }
                return result.trim();
        }

獲取CPU型號：

      public static String getCpuName() {
                try {
                        FileReader fr = new FileReader("/proc/cpuinfo");
                        BufferedReader br = new BufferedReader(fr);
                        String text = br.readLine();
                        String[] array = text.split(":\\s+", 2);
                        for (int i = 0; i < array.length; i++) {
                        }
                        return array[1];
                } catch (FileNotFoundException e) {
                        e.printStackTrace();
                } catch (IOException e) {
                        e.printStackTrace();
                }
                return null;
        }

不僅通過代碼可以獲取，也可以通過adb命令讀取/proc/cpuinfo來獲取：

adb shell cat /proc/cpuinfo
