1. 总内存(ram)
  android 内存信息在 /proc/meminfo中，可以通过读取此文件获取信息。
  public void getTotalMemory() {
               String str1 = "/proc/meminfo";
               String str2="";
               try {
                       FileReader fr = new FileReader(str1);
                       BufferedReader localBufferedReader = new BufferedReader(fr, 8192);
                       while ((str2 = localBufferedReader.readLine()) != null) {
                               Log.i(TAG, "---" + str2);
                       }
               } catch (IOException e) {
               }
       }
 2. 获取当前可用内存
   public long getAvailMemory() {
               ActivityManager am = (ActivityManager)mContext.getSystemService(Context.ACTIVITY_SERVICE);
               ActivityManager.MemoryInfo mi = new ActivityManager.MemoryInfo();
               am.getMemoryInfo(mi);
               return mi.availMem;
       }

 3. 获取rom大小
   public long[] getRomMemroy() {
               long[] romInfo = new long[2];
               File root = Environment.getRootDirectory();
               StatFs sf = new StatFs(root.getPath());
               long bSize = sf.getBlockSize();
               long bCount = sf.getBlockCount();
               long availBlocks = sf.getAvailableBlocks();
               romInfo[0] = bSize * bCount;// Total size
               romInfo[1] = bSize * availBlocks;// Available size
               return romInfo;
       }

 4. 获取SD卡容量
   public long[] getSDCardMemory() {
               long[] sdCardInfo=new long[2];
               String state = Environment.getExternalStorageState();
               if (Environment.MEDIA_MOUNTED.equals(state)) {
                       File sdcardDir = Environment.getExternalStorageDirectory();
                       StatFs sf = new StatFs(sdcardDir.getPath());
                       long bSize = sf.getBlockSize();
                       long bCount = sf.getBlockCount();
                       long availBlocks = sf.getAvailableBlocks();

                       sdCardInfo[0] = bSize * bCount;// Total size
                       sdCardInfo[1] = bSize * availBlocks;// Available size
               }
               return sdCardInfo;
       }

   5. 获取电量
      private BroadcastReceiver batteryReceiver=new BroadcastReceiver(){
               @Override
               public void onReceive(Context context, Intent intent) {
                       int level = intent.getIntExtra("level", 0);
                       //     level Plus % Is the current power of the
       }
       };
   在 activity中注册
   registerReceiver(batteryReceiver,new IntentFilter(Intent.ACTION_BATTERY_CHANGED));
 6. CPU信息
     public String[] getCpuInfo() {
               String str1 = "/proc/cpuinfo";
               String str2="";
               String[] cpuInfo={"",""};
               String[] arrayOfString;
               try {
                       FileReader fr = new FileReader(str1);
                       BufferedReader localBufferedReader = new BufferedReader(fr, 8192);
                       str2 = localBufferedReader.readLine();
                       arrayOfString = str2.split("\\s+");
                       for (int i = 2; i < arrayOfString.length; i++) {
                               cpuInfo[0] = cpuInfo[0] + arrayOfString[i] + " ";
                       }
                       str2 = localBufferedReader.readLine();
                       arrayOfString = str2.split("\\s+");
                       cpuInfo[1] += arrayOfString[2];
                       localBufferedReader.close();
               } catch (IOException e) {
               }
               return cpuInfo;
       }
