通过代码实现获取手机CPU信息

要获取手机CPU的基本信息可分为几类：CPU最高频率、CPU最低频率、CPU当前频率、CPU型号等。

以下是获取最高频率信息的代码：

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();
}

获取最低频率的代码
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();
}
获取当前频率：

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();
}

获取CPU型号：
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;
}

不仅通过代码可以获取，也可以通过adb命令读取/proc/cpuinfo来获取：

adb shell cat /proc/cpuinfo
