判断sd卡是否存在：

 public static boolean externalMemoryAvailable() {        return android.os.Environment.getExternalStorageState().equals(                android.os.Environment.MEDIA_MOUNTED);    }

获取手机内部储存空间：

public long getTotalMemo(){File path = Environment.getDataDirectory();        StatFs stat = new StatFs(path.getPath());        long blockSize = stat.getBlockSize();        long totalBlocks = stat.getBlockCount();        return totalBlocks * blockSize;       }

获取手机内部剩余存储空间：

public long getRemainMemo(){File path = Environment.getDataDirectory();        StatFs stat = new StatFs(path.getPath());        long blockSize = stat.getBlockSize();        long availableBlocks = stat.getAvailableBlocks();        return availableBlocks * blockSize;}

获取sd卡总存储空间：

public static long getTotalExternalMemorySize() {        if (externalMemoryAvailable()) {            File path = Environment.getExternalStorageDirectory();            StatFs stat = new StatFs(path.getPath());            long blockSize = stat.getBlockSize();            long totalBlocks = stat.getBlockCount();            return totalBlocks * blockSize;        } else {            return ERROR;        }    }}

获取sd卡剩余空间：

public static long getAvailableExternalMemorySize() {        if (externalMemoryAvailable()) {            File path = Environment.getExternalStorageDirectory();            StatFs stat = new StatFs(path.getPath());            long blockSize = stat.getBlockSize();            long availableBlocks = stat.getAvailableBlocks();            return availableBlocks * blockSize;        } else {            return ERROR;        }    }
