Android获取CPU信息(CPU名字和主频)

文章参照自： http://www.2cto.com/kf/201206/134236.html

在 Android 中，我们可以通过读取一些系统文件来获得手机的 cpu信息 (CPU 名字 和CPU 主频 )。

具体请参照实例1.

实例1

package edu . cdut . robin ; import java . io . BufferedReader ; import java . io . FileNotFoundException ; import java . io . FileReader ; import java . io . IOException ; public class CPUTool { private final static String kCpuInfoMaxFreqFilePath = "/sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_max_freq" ; public static int getMaxCpuFreq () { int result = 0 ; FileReader fr = null ; BufferedReader br = null ; try { fr = new FileReader ( kCpuInfoMaxFreqFilePath ); br = new BufferedReader ( fr ); String text = br . readLine (); result = Integer . parseInt ( text . trim ()); } catch ( FileNotFoundException e ) { e . printStackTrace (); } catch ( IOException e ) { e . printStackTrace (); } finally { if ( fr != null ) try { fr . close (); } catch ( IOException e ) { // TODO Auto-generated catch block e . printStackTrace (); } if ( br != null ) try { br . close (); } catch ( IOException e ) { // TODO Auto-generated catch block e . printStackTrace (); } } return result ; } private final static String kCpuInfoMinFreqFilePath = "/sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_min_freq" ; /* 获取CPU最小频率（单位KHZ） */ public static int getMinCpuFreq () { int result = 0 ; FileReader fr = null ; BufferedReader br = null ; try { fr = new FileReader ( kCpuInfoMinFreqFilePath ); br = new BufferedReader ( fr ); String text = br . readLine (); result = Integer . parseInt ( text . trim ()); } catch ( FileNotFoundException e ) { e . printStackTrace (); } catch ( IOException e ) { e . printStackTrace (); } finally { if ( fr != null ) try { fr . close (); } catch ( IOException e ) { // TODO Auto-generated catch block e . printStackTrace (); } if ( br != null ) try { br . close (); } catch ( IOException e ) { // TODO Auto-generated catch block e . printStackTrace (); } } return result ; } private final static String kCpuInfoCurFreqFilePath = "/sys/devices/system/cpu/cpu0/cpufreq/scaling_cur_freq" ; /* 实时获取CPU当前频率（单位KHZ） */ public static int getCurCpuFreq () { int result = 0 ; FileReader fr = null ; BufferedReader br = null ; try { fr = new FileReader ( kCpuInfoCurFreqFilePath ); br = new BufferedReader ( fr ); String text = br . readLine (); result = Integer . parseInt ( text . trim ()); } catch ( FileNotFoundException e ) { e . printStackTrace (); } catch ( IOException e ) { e . printStackTrace (); } finally { if ( fr != null ) try { fr . close (); } catch ( IOException e ) { // TODO Auto-generated catch block e . printStackTrace (); } if ( br != null ) try { br . close (); } catch ( IOException e ) { // TODO Auto-generated catch block e . printStackTrace (); } } return result ; } /* 获取CPU名字 */ public static String getCpuName () { FileReader fr = null ; BufferedReader br = null ; try { fr = new FileReader ( "/proc/cpuinfo" ); 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 (); } finally { if ( fr != null ) try { fr . close (); } catch ( IOException e ) { // TODO Auto-generated catch block e . printStackTrace (); } if ( br != null ) try { br . close (); } catch ( IOException e ) { // TODO Auto-generated catch block e . printStackTrace (); } } return null ; } }
