Android中如何判断sd卡容量是否小于某值

当在电话通话录音、照相、录音机等中全部要用到T卡容量大小胡判断：
  
[java]
public static boolean isAvaiableSpace(int sizeMb){  
 　if (android.os.Environment.getExternalStorageState().equals(android.os.Environment.MEDIA_MOUNTED))  
 {  
      String sdcard = Environment.getExternalStorageDirectory().getPath();  
//     File file = new File(sdcard);  
     StatFs statFs = new StatFs(sdcard);  
     long blockSize = statFs.getBlockSize();  
     long blocks = statFs.getAvailableBlocks();  
     long availableSpare = (blocks*blockSize)/(1024*1024);  
//     long availableSpare = (long) (statFs.getBlockSize()*((long)statFs.getAvailableBlocks()-4))/(1024*1024);//以比特计算 换算成MB  
     System.out.println("availableSpare = " + availableSpare);  
      if(sizeMb>availableSpare){  
      return false;  
     }else{  
      return true;  
     }  
 }  
   
  return false;   
 } 
 
      通过上面的方法，可以进行SD卡容量大小的判断了。
