Android获取机身存储、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 blocke.printStackTrace();}finally{}return path;}

返回/storage/sdcard1这就是我们想要的路径。

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;    }

返回bytes单位的大小。
