In this code ,I am trying to send image to server alongwith timeline_id .timeline_id contains the value pk that is the primary key of the user stored in the database.I am not able to send image with timeline_id.I don't know where the actual problem is.Please help me to resolve the issue.
You can simple put the file part along with the text part using the class below.
String charset = "UTF-8";
String requestURL = BASE_URL + "userregistration";
MultipartUtility multipart = new MultipartUtility(requestURL, charset);
multipart.addFormField("username", userJid);
multipart.addFilePart("image", imageBitmap);//ima
String response = multipart.finish();
Log.d("SERVER REPLIED", response);
You can create an MultipartUtility class as follow-
public class MultipartUtility {
private final String boundary;
private static final String LINE_FEED = "\r\n";
private HttpURLConnection httpConn;
private String charset;
private OutputStream outputStream;
private PrintWriter writer;
/**
* This constructor initializes a new HTTP POST request with content type
* is set to multipart/form-data
*
* @param requestURL
* @param charset
* @throws IOException
*/
public MultipartUtility(String requestURL, String charset)
throws IOException {
this.charset = charset;
boundary = "===" + System.currentTimeMillis() + "===";
URL url = new URL(requestURL);
httpConn = (HttpURLConnection) url.openConnection();
httpConn.setUseCaches(false);
httpConn.setDoOutput(true); // indicates POST method
httpConn.setDoInput(true);
httpConn.setRequestProperty("Content-Type",
"multipart/form-data; boundary=" + boundary);
httpConn.setRequestProperty("api_key", "a05f9ece-cd34-11e4-afdc-1681e6b88ec1");
outputStream = httpConn.getOutputStream();
writer = new PrintWriter(new OutputStreamWriter(outputStream, charset),
true);
}
/**
* Adds a form field to the request
*
* @param name field name
* @param value field value
*/
public void addFormField(String name, String value) {
writer.append("--").
append(boundary).

writer.flush();

writer.append(LINE_FEED);
writer.flush();
}
/**

*
* @param name - name of the header field
* @param value - value of the header field
*/
public void addHeaderField(String name, String value) {
writer.append(name).append(": ").append(value).append(LINE_FEED);
writer.flush();
}
/**

*
* @return a list of Strings as response in case the server returned
* status OK, otherwise an exception is thrown.
* @throws IOException
*/
public String finish() throws IOException {
writer.append(LINE_FEED).flush();
writer.append("--")
.append(boundary)
.append("--")
.append(LINE_FEED)
.close();
String data = "";
int status = httpConn.getResponseCode();

I have fixed the issue.Just need to do the following changes in the uploadFile() method.Everything is working file now.

String boundary = "*****";
int bytesRead, bytesAvailable, bufferSize;
byte[] buffer;
int maxBufferSize = 1 * 1024 * 1024;
File sourceFile = new File(fileName);
int pk = almabayDatabase.getUserID();
if (!sourceFile.isFile()) {
dialog.dismiss();
Log.e("uploadFile", "Source File not exist :" + imagepath);
runOnUiThread(new Runnable() {
public void run() {
// messageText.setText("Source File not exist :"+ imagepath);
Log.e("Sourcefile", "File doesn't exist");
}
});
return 0;
