Android获取机身储存、内置SD卡与外置TF卡路径

获取机身存储路径(可以通过openFileInput,openFileOutput进行操作)

String path=Environment.getDataDirectory().getAbsolutePath();返回/data

获取内置SD卡路径:

public String getStorageDir(){    	 if(!(Environment.getExternalStorageState().equals(Environment.MEDIA_MOUNTED))){    		 return "";    	 }    	 File dirFile=Environment.getExternalStorageDirectory();    	 Log.d(TAG, dirFile.getAbsolutePath());    	 return dirFile.getAbsolutePath();    }

返回/storage/emulated/o

获取外置TF卡路径：

思路：通过linux中的mount命令。

public String getTFDir(){		String path="";		try {			InputStream ins=Runtime.getRuntime().exec("mount").getInputStream();			BufferedReader reader=new BufferedReader(new InputStreamReader(ins));			String line="";			while((line=reader.readLine())!=null){				if(line.contains("sdcard")){					if(line.contains("vfat")||line.contains("fuse")){						String split[]=line.split(" ");						path=split[1];						Log.d(TAG,path);					}				}			}			reader.close();			ins.close();					} catch (IOException e) {			// TODO Auto-generated catch block			e.printStackTrace();		}finally{					}		return path;	}

获取可用空间

public static long getAvailableSize(String path){    try{        File base = new File(path);    StatFs stat = new StatFs(base.getPath());    long nAvailableCount = stat.getBlockSize() * ((long) stat.getAvailableBlocks());    return nAvailableCount;    }catch(Exception e){    e.printStackTrace();    }    return 0;    }
