    String MODEL = android.os.Build.MODEL;//型号

    String SDK = android.os.Build.VERSION.SDK;//SDK版本

    DisplayMetrics dm = new DisplayMetrics();
    WindowManager windowMgr = (WindowManager) getSystemService(Context.WINDOW_SERVICE);
    windowMgr.getDefaultDisplay().getMetrics(dm);
    int width = dm.widthPixels;
    int height = dm.heightPixels;
    String pixs = width + "*" + height;//分辨率


    File sdpath = Environment.getExternalStorageDirectory();
    StatFs sdstat = new StatFs(sdpath.getPath());
    long blockSize = sdstat.getBlockSize();
    long allBlocks = sdstat.getBlockCount();
    String SDcard = allBlocks * blockSize / 1024 / 1024+"";//SD卡大小

    File rompath = Environment.getDataDirectory();
    StatFs romstat = new StatFs(rompath.getPath());
    long romblockSize = romstat.getBlockSize();
    long romtotalBlocks = romstat.getBlockCount();
    String ROM = romtotalBlocks * romblockSize/1024/1024+"";//内存大小
