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) { e.printStackTrace(); } return "Unavailable"; }
