Android开发实现的获取sdcard大小及内存大小工具类

public class SDCardUtil {  /**   * SD卡   * @param context   */  public static void getSDCardInfo(Context context){    try {      File path = Environment.getExternalStorageDirectory();      StatFs s = new StatFs(path.getPath());      long availableBlocks = s.getAvailableBlocksLong();      long blockCount = s.getBlockCountLong();      long blockSize = s.getBlockSizeLong();      long totalsize = blockSize * blockCount;      long availsize = blockSize * availableBlocks;      String totalsizeStr = Formatter.formatFileSize(context, totalsize);      String availsizeStr = Formatter.formatFileSize(context, availsize);    } catch (Exception e) {      e.printStackTrace();    }  }  /**   * 手机内存   * @param context   */  public static void getDataInfo(Context context){    try {      File path = Environment.getDataDirectory();      StatFs s = new StatFs(path.getPath());      long availableBlocks = s.getAvailableBlocksLong();      long blockCount = s.getBlockCountLong();      long blockSize = s.getBlockSizeLong();      long totalsize = blockSize * blockCount;      long availsize = blockSize * availableBlocks;      String totalsizeStr = Formatter.formatFileSize(context, totalsize);      String availsizeStr = Formatter.formatFileSize(context, availsize);    } catch (Exception e) {      e.printStackTrace();    }  }}
