Android acquires body storage, built-in SD card and external TF card path

Source: Internet
Author: User

Get the body storage path (can be operated via Openfileinput,openfileoutput)
String path=environment.getdatadirectory (). GetAbsolutePath (); return/data
Get the built-in SD card path:

Public String Getstoragedir () {     if (! ( Environment.getexternalstoragestate (). Equals (environment.media_mounted)) {     return "";     }     File dirfile=environment.getexternalstoragedirectory ();     LOG.D (TAG, Dirfile.getabsolutepath ());     return Dirfile.getabsolutepath ();    }

Back to/storage/emulated/o

To obtain an external TF card path:

Idea: Through the Mount command in Linux.

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 ("");p ath=split[1]; LOG.D (Tag,path);}}} Reader.close (); Ins.close ();} catch (IOException e) {//TODO auto-generated catch Blocke.printstacktrace ();} Finally{}return path;}
Return/storage/sdcard1 This is the path we want.

Get free space

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;    }
Returns the size of the bytes unit.
