dropbox api - Android - Downloading File by updating Progress Bar -
i have multiple files in dropbox account. downloading files. want show progress bar percentage when files gets downloaded.the progress bar finishes.i using asynctask downloading files.here code.
public void onpreexecute(){ mdialog = new progressdialog(mcontext); mdialog.setprogressstyle(progressdialog.style_horizontal); mdialog.setmax(100); mdialog.show(); } public void downloadfiles(string filename){ log.i("item name",filename); file dir = null; boolean issdpresent = android.os.environment.getexternalstoragestate().equals(android.os.environment.media_mounted); if(issdpresent){ file sdcard = environment.getexternalstoragedirectory(); dir = new file (sdcard.getabsolutepath() + "/allsecure"); if (!dir.exists()) { dir.mkdirs(); } }else{ dir = mcontext.getdir("users", context.mode_private); //creating internal dir; if(!dir.exists()) { dir.mkdirs(); } } file file = new file(dir, filename); try { fileoutputstream mfileoutputstream=new fileoutputstream(file); dropboxfileinfo mdropboxfileinxfo=mapi.getfile(photo_dir + filename, null, mfileoutputstream, null); } catch (filenotfoundexception e) { // todo auto-generated catch block e.printstacktrace(); } catch (dropboxexception e) { // todo auto-generated catch block e.printstacktrace(); } } protected string doinbackground(string... params) { sessionutil ses = new sessionutil(mcontext); androidauthsession session = ses.buildsession(); mapi = new dropboxapi<androidauthsession>(session); entry entries = null; try { system.out.println("mapi " + mapi); entries = mapi.metadata(photo_dir, 10000, null, true, null); } catch (dropboxexception e1) { // todo auto-generated catch block e1.printstacktrace(); } (entry e : entries.contents) { if (!e.isdeleted) { //log.i("is folder",string.valueof(e.isdir)); downloadfiles(e.filename()); mfilelen = entries.bytes; log.i("item name",e.filename()); } } return null; } protected void onprogressupdate(integer... progress) { } @override protected void onpostexecute(string result) { mdialog.dismiss(); }
you need call publishprogress method in doinbackground . need pass progress argument publishprogress method.
for example:
protected string doinbackground(string... params) { sessionutil ses = new sessionutil(mcontext); androidauthsession session = ses.buildsession(); mapi = new dropboxapi<androidauthsession>(session); entry entries = null; try { system.out.println("mapi " + mapi); entries = mapi.metadata(photo_dir, 10000, null, true, null); } catch (dropboxexception e1) { // todo auto-generated catch block e1.printstacktrace(); } int max = entries.contents.size(); // 2 variables need calculate progress int current = 0; (entry e : entries.contents) { if (!e.isdeleted) { //log.i("is folder",string.valueof(e.isdir)); downloadfiles(e.filename()); mfilelen = entries.bytes; log.i("item name",e.filename()); current++; //calculate progress publishprogress(100 * current / max); //then pass } } return null; } after publishprogress called onprogressupdate invoked.
you need handle progress update
protected void onprogressupdate(integer... progress) { integer p = progress[0]; mdialog.setprogress(p); mdialog.setmessage(string.format("%d%%", p)); //if need see progress percentage in dialog's text }
