Android获取系统储存以及内存信息(二)

Android获取储存信息以及内存信息可以用adb命令查看。

adb查看系统内存信息以及储存信息：

命令:adb shell cat /proc/meminfo 

代码:

 private static final String FILENAME_PROC_MEMINFO = "/proc/meminfo";
/**
  * 获取手机内存总大小
  * @return
  */
 public static String getTotalMemorySize() {
        try {
            FileReader fr = new FileReader(FILENAME_PROC_MEMINFO);
            BufferedReader br = new BufferedReader(fr, 2048);
//            String memoryLine = br.readLine();
            String subMemoryLine = "";
            String Line = "";
            while ((Line = br.readLine()) != null)
            {
                if (Line.contains("MemTotal:")){
                    subMemoryLine = Line.substring(Line.indexOf("MemTotal:"));
                    break;
                }

            }
            br.close();
            Matcher mer = Pattern.compile("^[0-9]+$").matcher(subMemoryLine.replaceAll("\\D+", ""));
            //如果为正整数就说明数据正确的，确保在Double.parseDouble中不会异常
            if (mer.find()) {
                long memSize = Integer.parseInt(subMemoryLine.replaceAll("\\D+", "")) ;
                double mem = (Double.parseDouble(memSize + "")/1024)/1024;
                NumberFormat nf = new DecimalFormat( "0.0 ");
                mem = Double.parseDouble(nf.format(mem));
                //Log.e(LOG_TAG,"=========mem================ " + mem);
                return String.valueOf(mem);
            }
        } catch (IOException e) {
            e.printStackTrace();
        }
        return "Unavailable";
    }

   /**
     * 获取手机剩余内存大小
     * @return
     */
    public static String getFreeMemorySize() {
        try {
            FileReader fr = new FileReader(FILENAME_PROC_MEMINFO);
            BufferedReader br = new BufferedReader(fr, 2048);
//            String memoryLine = br.readLine();
            String subMemoryLine = "";
            String Line = "";
            while ((Line = br.readLine()) != null)
            {
                if (Line.contains("MemFree:")){
                    subMemoryLine = Line.substring(Line.indexOf("MemFree:"));
                    break;
                }

            }
            br.close();
            Matcher mer = Pattern.compile("^[0-9]+$").matcher(subMemoryLine.replaceAll("\\D+", ""));
            //如果为正整数就说明数据正确的，确保在Double.parseDouble中不会异常
            if (mer.find()) {
                long memSize = Integer.parseInt(subMemoryLine.replaceAll("\\D+", "")) ;
                double mem = (Double.parseDouble(memSize + "")/1024)/1024;
                NumberFormat nf = new DecimalFormat( "0.0 ");
                mem = Double.parseDouble(nf.format(mem));
                //Log.e(LOG_TAG,"=========mem================ " + mem);
                return String.valueOf(mem);
            }
        } catch (IOException e) {
            e.printStackTrace();
        }
        return "Unavailable";
    }

adb 获取手机储存大小：

命令:adb shell cat /proc/partitions 

代码：

private static final String FILENAME_PROC_EMMCINFO = "/proc/partitions";
 /**
     * 获取手机储存大小
     * @return
     */
 public static String getEmmcSize() {
        try {
            FileReader fr = new FileReader(FILENAME_PROC_EMMCINFO);
            BufferedReader br = new BufferedReader(fr, 2048);
            String Line = "";
            String EmmcSize = "";
            while ((Line = br.readLine()) != null)
            {
                if (Line.length() >7 && Line.lastIndexOf(" ") > 0) {
                    if (Line.substring(Line.lastIndexOf(" ") + 1 , Line.length()).equals("mmcblk0"))
                    {

                        EmmcSize = removeAllSpace(Line);
                        break;
                    }
                }

            }
            br.close();
            if (EmmcSize.length() >7 ){
                EmmcSize = (String) EmmcSize.subSequence(4, EmmcSize.length()-7);

                Matcher mer = Pattern.compile("^[0-9]+$").matcher(EmmcSize);
                //如果为正整数就说明数据正确的，确保在Double.parseDouble中不会异常
                if (mer.find()) {
                    double mem = (Double.parseDouble(EmmcSize)/1024)/1024;
                    NumberFormat nf = new DecimalFormat( "0.0 ");
                    mem = Double.parseDouble(nf.format(mem));
                    return String.valueOf(mem);
                }
            }
            return "0";
        } catch (IOException e) {
