Android downloading bitmap from url -

-

I have one more minor problem, I have a link to my picture in the standard format, but by the end of the entry Auth Token is the image needed, so whenever I type it in my webbrowser with the correct auth token image, it is automatically downloaded. And here's my question, how do I support playing this kind of image in Bitmap on Android? Because 

  using the final URL bitmapUrl = new URL (imageUrl); Bitmap = bitmapfile SingleStream (Bitmap URL. Open Connection). GetInputStream ());

does not work ... 

  private Bitmap GetBitmap (string url) {file f = fileCache.getFile (url); // bitmap b = decodfile (s) from SD cache; If (b! = Null) return b; // Try the Web {bitmap bitmap = null; URL imageUrl = New URL (url); HttpURLConnection conn = (HttpURLConnection) imageUrl.openConnection (); Conn.setConnectTimeout (70000); Conn.setReadTimeout (70000); Conn.setRequestProperty ("Auth_keyName", "Value"); // If required authentication conn.setInstanceFollowRedirects (true); InputStream = conn.getInputStream (); OutputStream OS = New FileOutputStream (f); Utilis Copyright Stream (IS, OS); Os.close (); Conn.disconnect (); Bitmap = decodefile (f); Return bitmap; } Catch (Throwable Pre) {ex.printStackTrace (); If (Expression of OutofMemory Error) Memory Cache clear (); Return tap; }}

I have a requirement whenever I run my own kettle, dynamically took database connection parameters from an excel source Every run should go. I have an Excel column names: hostname, username, database, password. I want to pass these connection parameters to my table input stage dynamically whenever it runs the job. This is what I was trying to do. You can get it Connection parameters from the DB reading source (for example Excel or a CSV file in my example) < / Li> Store the parameters in the variable Using the variable in your connection's settings. Setting Variables Create another conversion for (you can not do it in the same conversion Uses): set variables element variable: The element that reads / writes your data creates a new connection and sets the connection parameter using $ {variable name_} Note that you will need to type in the field field in the field $ {password} Also keep in mind that this can be a security problem as the

I am trying to implement a screen-scraps application that opens a URL in which a parameter changes as it is for a loop: var data = [ '100', '101', '102', '103', '104']; (Var indexA = 0; indexA & lt; data.length; indexA ++) for {Phantom Generation ({'port': freeport}, function (pH) {ph.create page (function (page) {page.open ("http: //...++ data [index B] +" ... " , Status {console.log ("open site:" + data [index B], position); / * OLD * / indexB ++; page evaluation (function () {// page scrape and an object Return}, function {console.log (result.dataRequest); // here is the problem}); / * new and fixed * / indexB ++} first console Logs it: Open Site: 100 Success Opens Site: 101 Success B Ola Site: 102 Success Opening Site: 103 Success Opened Site: 104 Success Which is good. Data is verified in scrap HTML and from index to array Matches. So in page 101 I scrap '101 and retrieve' and pu
