Android 最新获取手机内置存储大小，SD卡存储空间大小步骤

在以前我们都是这样获取的

//Android API18之前：fs.getAvailableBlocks()*fs.getBlockSize()

目前：

/** 得到系统可用内存 **/	@SuppressLint("NewApi")	private String getMemFree(){		StatFs fs = new StatFs(Environment.getDataDirectory().getPath());		return Formatter.formatFileSize(this, (fs.getAvailableBytes()));	}		/** 得到SD可用内存 **/	@SuppressLint("NewApi")	private String getSdFree(){		if(Environment.getExternalStorageState().equals(Environment.MEDIA_MOUNTED)){ 			StatFs fs = new StatFs(Environment.getExternalStorageDirectory().getPath());			//Android API18之前：fs.getAvailableBlocks()*fs.getBlockSize()			return Formatter.formatFileSize(this, (fs.getAvailableBytes()));		}		return "未装载";	}

终于解决问题了，嘎嘎
