Using Base64 encoded characters as filename in Android app -

-

I'm trying to create file names in my Android app with a 4 byte byte array. I am encoding the base 64 to the byte array with the URL_SAFE option. However, the generated string ends with a new character, which makes it void in the file name, there is no way to remove the new line ?

My code is as follows: 

  byte [] myByteArray = new byte [4]; MyByteArray = myByteArray; // Some data fills the byte array with the final string byte sting = base 64. encodeToString (myByteArray, Base64.URL_SAFE); After some googling, I found out that in Android, Base64 encoding automatically includes a new line after the string, and that it will be resolved using NO_WRAP flag though, is the NO_WRAP flag generated output filename safe? 
 
 Thank you.

OK, it shows that I want to implement both flags (Base64.URL_SAFE | Base64 .NO_WRAP).

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
