How to Show download progress in progress bar in Android? -

-

I am using Net Web Services and I am able to download the file to the SD card, but I can see the progress bar I want to show when a special file is downloaded and is complete and then I want to see the options such as viewing or canceling.

Click on event class: 

  public void onItemClick (AdapterView & lt;? & Gt; parent, see v, int status, long id) {casual adapter ca = (LazyAdapter) parent.getAdapter (); Folder list item_name = (folder list) ca.getItem (status); Folder list document id = (folder list) ca.getItem (status); Folder list type = (folder list) ca.getItem (status); Intent mIntent = new intent (); MIntent.putExtra ("item_name", item_name.folder_name); MIntent.putExtra ("item_id", DocumentID.ID); MIntent.putExtra ("item_type", type.type); MIntent.getStringExtra ("ITEM_NAME"); String type = mIntent.getStringExtra ("item_type"); Log.i ("type", type); If // some code here .....} and {intent I = new intent (getApplicationContext (), Display_image.class); I.putExtra ("item_name", item_name.folder_name); I.putext ("id", DocumentID.ID); I.putext ("item_type", type.type); I.putExtra ("user_id", user_id); I.getStringExtra ("ITEM_NAME"); Id = i.getStringExtra ("id"); I.getStringExtra ("item_type"); StartActivity (i); }}}); }   
 My code: I want to use the download manager  
  Soppromiry Document Response = (Sopprimiv) Envelope; Tetresons (); Log.i ("DocumentResponse", DocumentResponse.toString ()); String DocAsString = DocumentResponse.toString (); Byte [] decoded string = base 64 decode (docstestring, base64.default); Direct file = new file (environment .getExternalStorageDirectory (+ + "/ MyFolder"); If (! Direct.exists ()) {direct.mkdir (); } File photo = new file (environment .getExternalStorageDirectory () + "/ MyFolder", name); If (photo.exists ()) {photo.delete (); } {Try DownloadManager.Request = New DownloadManager.Request (Uri.parse (name)); Request.setDescription ("Have Fun;)"); Request.setTitle ("Downloading ..."); // In order of this to run, if you (Build.VERSION.SDK_INT> = Build.VERSION_CODT.HONEYCOMB) should use Android 3.2 to compile your app. {Request.allowScanningByMediaScanner (); Request.setNotificationVisibility (DownloadManager.Request.VISIBILITY_VISIBLE_NOTIFY_COMPLETED); } FileOutputStream fos = New FileOutputStream (photo.getPath ()); Fos.write (decodedString); Fos.close (); DownloadManager Manager = (DownloadManager) getSystemService (reference.DOWNLOAD_SERVICE); Manager.enqueue (request); Material values ​​= new material value (); Println (value); } Hold (java.io.IOException e) {Log.e ("Picture Dmo", "Exception in Photoklback", e); }}   
 How to use Download Manager in ??? Thank you   
 
 
 You can use a progress to complete it.  
  
  Android: Android: Android: Android: layout_width = "wrap-content" Android: layout_height = "wrap_content"  
 First, one such progress bar on your interface: Style = "@ android: style / widget.progressbar.small" />   
 Then update your code in this way:  
  Protected progress Berg mprogressbar; Protected long download id; Protected DownloadManager Manager; Public Zero Start Download () {// & lt; SET UP Download Manager & gt; Download id = manager.query (request); MProgressBar = findViewById (R.id.progress_bar); Timer myitimer = new timer (); MyTimer.schedule (New TimerTask) {@Override Public Zero Run () {DownloadManager.Query q = New DownloadManager.Query (); Q.setFilterById (downloadId); Cursor cursor = manager.query (q); Cursor.moveToFirst (); Int bytes_downloaded = cursor.getInt (cursor.getColumnIndex (DownloadManager.COLUMN_BYTES_DOWNLOADED_SO_FAR)); Int bytes_total = cursor.getInt (cursor.getColumnIndex (DownloadManager.COLUMN_TOTAL_SIZE_BYTES)); Cursor.co.us (); Int dl_progress = (bytes_loaded * 100 / Bytes_total); RunOnTabrade (New Runnabal) {@ Override Public Wired Run () {mProgressbar.setProgress (dl_progress)}}}}}}}, 0, 10); }

-
After opening several examples of macro / code written, I suddenly get stuck with a code that seems safe. Solver (SOLVER.XLAM) is doing this notation and I would like to remove it from my system. I do not think this is a relativant code. Can anyone tell me what should I do? I have already installed something to remove the password but Solver is still asking for password and I can not get rid of it! itemprop = "text"> Solver Excel is add-in If you want to delete it, then Excel Application & gt; Options & gt; Add-ins & gt; Search for 'Go to' button and gt; Uncheck the solver on the list like press something (I can not give you the exact path because I have the Polish version of Excel). Trying to open Solver's VBA code is not good because it There is allegedly copyright. Besides, I do not think Solver creates any disadvantages while working with Excel or VBA.

github - Teamcity & Git - PR merge builds - anyway to get HEAD commit hash? -

-
I have a team city build project with Gitbab VCS route, I have been triggered for both / head on PR and / Merge the referee. The annoying thing is that you can not do anything useful with the merged hash - it is not present in Gitobb. I want to exclude newsgate packages with head in gutub comet situations in the version number along with Hewash (Newsaging 7) for the music build, but against head hash. However, I can not see a way to get the head hashes while constructing that merge. I just want to head because it's useless - we only care about merge. (PR - Pull Request) This command works reliably while running One on / merge is git log --no-merge -1 ---- = '% h'
