Get file ID in skydrive SDK Android -

i'm making app can download file skydrive. app using skydrive sdk. i've found piece of code can download file skydrive android device below:

final livedownloadoperation operation = mclient.downloadasync(fileid + "/content", file, new livedownloadoperationlistener() {                         @override                         public void ondownloadprogress(int totalbytes, int bytesremaining, livedownloadoperation operation) {                             int percentcompleted = computeprecentcompleted(totalbytes, bytesremaining);                              progressdialog.setprogress(percentcompleted);                         }                          @override                         public void ondownloadfailed(liveoperationexception exception, livedownloadoperation operation) {                             progressdialog.dismiss();                             showtoast(exception.getmessage());                         }                          @override                         public void ondownloadcompleted(livedownloadoperation operation) {                             progressdialog.dismiss();                             showtoast("file downloaded.");                         }                     }); 

but don't know fileid skydrive make code works. it's awesome if have example

i've find solution self. list of file, compare finding file id. here code:

public list<dfile> getfileidfromname(string filename) {     dfile res = null;     // list<dfile> dolphinlistfile = getlistfile(dir_home);     // (dfile dolphin : dolphinlistfile) {     // if (dolphin.getfilename().compareto(filename) == 0)     // res = dolphin;     // }     boolean cangetid = true;     if (!isloggedin()) {         ongetidfromfilenamechecked(null, "not logged in or check session false");         cangetid = false;     }     if (cangetid) {         mfilelist = new arraylist<dfile>();         final string mfilename = filename;         mclient.getasync(dir_home + "/files", new liveoperationlistener() {             @override             public void oncomplete(liveoperation operation) {                  jsonobject result = operation.getresult();                 if (result.has(jsonkeys.error)) {                     jsonobject error = result.optjsonobject(jsonkeys.error);                     string message = error.optstring(jsonkeys.message);                     string code = error.optstring(jsonkeys.code);                     log.d("dolphin download err", code + ": " + message);                     return;                 }                 jsonarray data = result.optjsonarray(jsonkeys.data);                  (int = 0; < data.length(); i++) {                     skydriveobject skydriveobj = skydriveobject.create(data.optjsonobject(i));                      skydriveobj.accept(new visitor() {                         @override                         public void visit(skydrivealbum album) {                             mdfile = new dfile(album.getid(), "n/a", album.getname(), dfile.filehost_skydrive, dfile.filetype_album);                          }                          @override                         public void visit(skydrivephoto photo) {                             mdfile = new dfile(photo.getid(), "n/a", photo.getname(), dfile.filehost_skydrive, dfile.filetype_photo);                         }                          @override                         public void visit(skydrivefolder folder) {                             mdfile = new dfile(folder.getid(), "n/a", folder.getname(), dfile.filehost_skydrive, dfile.filetype_folder);                         }                          @override                         public void visit(skydrivefile file) {                             mdfile = new dfile(file.getid(), "n/a", file.getname(), dfile.filehost_skydrive, dfile.filetype_file);                         }                          @override                         public void visit(skydrivevideo video) {                             mdfile = new dfile(video.getid(), "n/a", video.getname(), dfile.filehost_skydrive, dfile.filetype_video);                         }                          @override                         public void visit(skydriveaudio audio) {                             mdfile = new dfile(audio.getid(), "n/a", audio.getname(), dfile.filehost_skydrive, dfile.filetype_audio);                         }                     });                     if (mdfile.getfilename().compareto(mfilename) == 0) {                         mfilelist.add(mdfile);                     }                 }                 ongetidfromfilenamechecked(mfilelist, "complete");             }              @override             public void onerror(liveoperationexception exception, liveoperation operation) {                  log.d("dolphin download err", exception.getmessage());                 ongetlistchecked(null, exception.getmessage());             }         });     }     return mfilelist; }
