The Method Setrequestproperty(string, String) In The Type Urlconnection Is Not Applicable For The Arguments (string, Arraylist)

I am trying to send multiple images to server but,so I am storing all the images in one arraylist,but after that when I need to send to server,it shows error near line ,,..........

Solution 1:

You can send String parameter as both field with setRequestProperty()

Problem : In second parameter, you are passing ArrayList<String>

Try to pass every element of multimgss one by one with setRequestProperty()

FileInputStreamfileInputStream=newFileInputStream(sourceFile);
           URLurl=newURL(upLoadServerUri);

           // Open a HTTP  connection to  the URL
           conn = (HttpURLConnection) url.openConnection(); 
           conn.setDoInput(true); // Allow Inputs
           conn.setDoOutput(true); // Allow Outputs
           conn.setUseCaches(false); // Don't use a Cached Copy
           conn.setRequestMethod("POST");
           conn.setRequestProperty("Connection", "Keep-Alive");
           conn.setRequestProperty("ENCTYPE", "multipart/form-data");
           conn.setRequestProperty("Content-Type", "multipart/form-data;boundary=" + boundary);

           conn.setRequestProperty("name", pname);
           conn.setRequestProperty("categoryid", catsids);
           conn.setRequestProperty("skucode", pskucode);
           conn.setRequestProperty("sale_rate", psalerate);
           conn.setRequestProperty("purchase_rate", ppurchaserate);
           conn.setRequestProperty("weight", pweight);
           conn.setRequestProperty("weighttype", pweighttype);
           conn.setRequestProperty("description", pdesc);


          conn.setRequestProperty("image", multimgss.get(i++));   
           // it will give i th element 

Note : From Android Developer documentation for setRequestProperty()

Sets the value of the specified request header field. The value will only be used by the current URLConnection instance. This method can only be called before the connection is established.

So, you need to call this method everytime before establishing connection

Solution 2:

setRequestProperty method only accept String instead of ArrayList . get JSONArray from ArrayList as:

JSONArray jsonArrayImgs=newJSONArray();
 ArrayList<String> multimgss=newArrayList<String>();
 for (Stringstring : multimgss)
  {
    jsonArrayImgs.put(string);
  }

Now pass jsonArrayImgs to setRequestProperty :

conn.setRequestProperty("image", jsonArrayImgs.toString()); 

EDIT:

sourceFileUri is null . so update getItem method as of Adapter:

public String getItem(int position) {
       return arrayList.get[position];
   }

now inside onItemClick of GridView asign selected image path to sourceFileUri as:

publicvoidonItemClick(AdapterView<?> parent, 
        View v, int position, long id){                
             imagepath=objImageAdapter.getItem(position);
        }
