Returns size in MegaBytes.

If you need calculate external memory, change this: 
   StatFs statFs = new StatFs(Environment.getRootDirectory().getAbsolutePath());
to this: 
   StatFs statFs = new StatFs(Environment.getExternalStorageDirectory().getAbsolutePath());

    public long totalMemory()
    {
        StatFs statFs = new StatFs(Environment.getRootDirectory().getAbsolutePath());   
        long   total  = (statFs.getBlockCount() * statFs.getBlockSize()) / 1048576;
        return total;
    }

    public long freeMemory()
    {
        StatFs statFs = new StatFs(Environment.getRootDirectory().getAbsolutePath());
        long   free   = (statFs.getAvailableBlocks() * statFs.getBlockSize()) / 1048576;
        return free;
    }

    public long busyMemory()
    {
        StatFs statFs = new StatFs(Environment.getRootDirectory().getAbsolutePath());   
        long   total  = (statFs.getBlockCount() * statFs.getBlockSize()) / 1048576;
        long   free   = (statFs.getAvailableBlocks() * statFs.getBlockSize()) / 1048576;
        long   busy   = total - free;
        return busy;
    }
