Send JSON and image with HttpURLConnection in android

i'm trying to send some data to a server. The server is waiting a json and an image. I tried with every example that i found but i couldn't send the data. Actually i'm sending the json params with a PrintWriter object, but it doesn't accept the image. I need to use HttpURLConnection not with the apache library. This is my piece of code working:
HttpURLConnection connection = null;
PrintWriter output = null;
ByteArrayOutputStream stream = new ByteArrayOutputStream();
attachImage.compress(Bitmap.CompressFormat.PNG, 40, stream);
byte[] imageData = stream.toByteArray();
String imagebase64 = Base64.encodeToString(imageData, Base64.DEFAULT);
Log.d(tag, "POST to " + url);
try{
URL url = new URL(this.url);
connection = (HttpURLConnection) url.openConnection();
connection.setRequestMethod("POST");
connection.setDoInput(true);
connection.setDoOutput(true);
connection.setUseCaches(false);
connection.setRequestProperty(HTTP_CONTENT_TYPE, "application/json; charset=utf-8");
connection.setRequestProperty(HTTP_USER_AGENT, mUserAgent);
connection.setRequestProperty(HTTP_HEADER_ACCEPT, "application/json; charset=utf-8");
connection.connect();
output = new PrintWriter(connection.getOutputStream());
JSONObject jsonParam = new JSONObject();
jsonParam.put("oauth_token", params.get("oauth_token"));
jsonParam.put("rating", "1");
jsonParam.put("comments", "ASDASDASDASDASDASDAS");
Log.d(tag, jsonParam.toString());
output.print(jsonParam);
output.flush();
output.close();
Log.d(tag, connection.getResponseCode() + connection.getResponseMessage());
}catch(Exception e ){
}
When I try to send an image in json params, I receive an 500 internal error message.
Thanks!

Okay , as per my suggestion 2 ways to send image to server
use base 64 string
Direct upload to server
1.for base 64 go to below link
Android post Base64 String to PHP
2.for direct upload to server Please check below link
http://www.androidhive.info/2014/12/android-uploading-camera-image-video-to-server-with-progress-bar/
Happy coding !!

People! After a lot of day, i could upload an image to a server! I was reading this library, which is for a lot of uses. https://source.android.com/reference/com/android/tradefed/util/net/HttpMultipartPost.html
I downloaded the source code, and i took some clases to send an image. I send only bytes, which were encoded from ASCII. Thanks for the help!

Check this below code to send form data and zip file containing images or other any media files.

you can upload large jsonstring using buffer please use bellow code .
HttpsURLConnection connection = null;
OutputStream os = null;
InputStream is = null;
InputStreamReader isr = null;
try {
connection = (HttpsURLConnection) url.openConnection();
SSLContext contextSSL = SSLContext.getInstance("TLS");
contextSSL.init(null, new TrustManager[]{new DefaultTrustManager()}, new SecureRandom());
HttpsURLConnection.setDefaultSSLSocketFactory(contextSSL.getSocketFactory());
MySSLFactory(context.getSocketFactory()));
HttpsURLConnection.setDefaultHostnameVerifier(new MyHostnameVerifier());
connection.setDoInput(true);
connection.setDoOutput(true);
connection.setUseCaches(false);
connection.setChunkedStreamingMode(0);
connection.setRequestMethod("POST");
connection.setRequestProperty("Content-Type", "application/json");
connection.setRequestProperty("Accept", "application/json");
connection.setRequestProperty("Authorization", auth);
connection.setConnectTimeout(timeoutMillis);
OutputStream os ;
if (input != null && !input.isEmpty()) {
os = connection.getOutputStream();
InputStream stream = new ByteArrayInputStream(input.getBytes(StandardCharsets.UTF_8));
BufferedInputStream bis = new BufferedInputStream(stream, 8 * 1024);
byte[] buffer = new byte[8192];
int availableByte = 0;
while ((availableByte = bis.read(buffer)) != -1) {
os.write(buffer, 0, availableByte);
os.flush();
}
}
int responseCode = connection.getResponseCode();

HTTP 500 error code means a server-side error occured.
This has nothing to do with your code.
The server is having a bug, not your code.

how to send file from sd card to http post?

}
return null;
It is working fine.but empty file is created in server.
If any one know the solution ,please help me .
Thanks in advance.

Try this code. It is using a class "SimpleMultipartEntity" using which you can easily send the file.

I'd prefer using Apache Http commons, it is part of android. I think this is a much simpler and cleaner approach. You need to do something like this:
AndroidHttpClient client = AndroidHttpClient.newInstance("useragent string");
URI uri = "something";
File file = new File("/tmp/data");
HttpPost post = new HttpPost(uri);
post.setEntity(new FileEntity(file, "text/html"));
HttpResponse httpResponse = client.execute(post);
int statusCode = httpResponse.getStatusLine().getStatusCode();

uploading video from android device and post that video on server

Can Any one have sample/example code for uploading video from android through my android application and store that video on server side.
Thanks in advance..

Here is another example. Very similar but the biggest difference is this is a data class designed to allow other post variables with it also. For example you have a specific file store for different users and groups. You then would want to send that data with the video. This data class can actually be used for all post to your site. So the data class is
public class MultiPartData {
final String requestURL = "http://www.yoursite.com/some.php";
final String charset="UTF-8";
final String boundary="*******";
private static final String LINE_FEED = "\r\n";
private HttpURLConnection httpConn;
private DataOutputStream outputStream;
private PrintWriter writer;
//establishes connection
public MultiPartData() throws IOException {
URL url = new URL(requestURL);
httpConn = (HttpURLConnection) url.openConnection();
httpConn.setUseCaches(false);
httpConn.setChunkedStreamingMode(4096);
httpConn.setDoOutput(true); // indicates POST method
httpConn.setDoInput(true);
httpConn.setRequestMethod("POST");
httpConn.setRequestProperty("ENCTYPE", "multipart/form-data");
httpConn.setRequestProperty("Content-Type",
"multipart/form-data; boundary=\"" + boundary + "\"");
httpConn.setRequestProperty("Connection", "Keep-Alive");
outputStream = new DataOutputStream(httpConn.getOutputStream());
writer = new PrintWriter(new OutputStreamWriter(outputStream, charset),true);
}
//adds post variables to the header body
public void addFormField(String name, String value) {
writer.append("--" + boundary).append(LINE_FEED);
writer.append("Content-Disposition: form-data; name=\"").append(name).append("\"")
.append(LINE_FEED);
writer.append("Content-Type: text/plain; charset=" + charset).append(
LINE_FEED);
writer.append(LINE_FEED);
writer.append(value).append(LINE_FEED);
writer.flush();
}
//adds files to header body can be anytype of files
public void addFilePart(String fieldName, String filePath) throws IOException {
File uploadFile=new File(filePath);
String fileName = uploadFile.getName();
writer.append("--" + boundary).append(LINE_FEED);
writer.append("Content-Disposition:form-data; name=\"")
.append(fieldName).append("\"; filename=\"")
.append(fileName).append("\"")
.append(LINE_FEED);
writer.append("Content-Type: ").append(URLConnection.guessContentTypeFromName(fileName))
.append(LINE_FEED);
writer.append("Content-Transfer-Encoding: binary").append(LINE_FEED);
writer.append(LINE_FEED);
writer.flush();
FileInputStream inputStream = new FileInputStream(uploadFile);
int maxBufferSize=2*1024*1024;
int bufferSize;
int bytesAvailable=inputStream.available();
bufferSize = Math.min(bytesAvailable, maxBufferSize);
byte[] buffer = new byte[bufferSize];
int bytesRead=inputStream.read(buffer);
do {
outputStream.write(buffer, 0, bytesRead);
bytesAvailable = inputStream.available();
bufferSize = Math.min(bytesAvailable, maxBufferSize);
bytesRead = inputStream.read(buffer, 0, bufferSize);
}while (bytesRead >0);
outputStream.flush();
inputStream.close();
writer.append(LINE_FEED);
writer.flush();
}
//adds header values to body
public void addHeaderField(String name, String value) {
writer.append(name).append(": ").append(value).append(LINE_FEED);
writer.flush();
}
//closing options you must use one of the options to close the connection
// finishString() gets results as a string
// finnishJOBJECT() gets results as an JSONObject
// finnishJARRAY() gets results as an JSONArray
// finnishNoResponse() closes connection with out looking for response
public String finishString() throws IOException {
String response = "";
writer.append(LINE_FEED).flush();
writer.append("--" + boundary + "--").append(LINE_FEED);
writer.close();
String line;
StringBuilder sb= new StringBuilder();
BufferedReader br = new BufferedReader(new InputStreamReader(httpConn.getInputStream(), "UTF-8"));
while ((line=br.readLine()) != null) {
sb.append(line);
response =sb.toString();
}
br.close();
return response;
}
public JSONObject finnishJOBJECT() throws IOException, JSONException {

}
public void finnishNoResponse(){

}
}
An example AsyncTask to implement the data class would be.
public void storeVideoBackground(String filePath,String identifier,String vType,String vName, storeImage serverPath){
progress.show();
new storeVideoAsyncTask(filePath,identifier,vType,vName,serverPath).execute();
}
public class storeVideoAsyncTask extends AsyncTask<Void,Void,String>{
String filePath; //path of the file to be uploaded
String vType; //variable used on server
String vName; //variable used on server
String identifier; //variable used on server
storeImage serverPath; //interface used to get my response
MultiPartData upload; //declares the data class for posting
public storeVideoAsyncTask(String filePath,String identifier,String vType,String vName, storeImage serverPath){
this.filePath=filePath;
this.vName=vName;
this.vType=vType;
this.identifier=identifier;
this.serverPath=serverPath;
}
#Override
protected String doInBackground(Void... params) {
JSONObject result;
String sPath="";
try {
upload=new MultiPartData();
upload.addHeaderField("User-Agent", "Android-User");
upload.addHeaderField("Test-Header","Header-Value");
upload.addFormField("appAuth",auth); //an auth string compared on server
upload.addFormField("action","storeVideo");//added post variable
upload.addFormField("vName",vName);//added post variable
upload.addFormField("identifier",identifier);//added post variable
upload.addFormField("vType",vType);//added post variable
upload.addFilePart("video",filePath);//added file video is the reference on server side to retrieve the file
sPath=upload.finishString();//returned server path to be used later
} catch (IOException e) {
e.printStackTrace();
}
return sPath;
}
#Override
protected void onPostExecute(String servPath) {
super.onPostExecute(servPath);
progress.dismiss();
serverPath.done(servPath);
}
}
Now I like reusing my code so this is part of another class called ServerRequest. I pass the context into it for progress dialog and declare other values like my appAuth.
The file is retrieved like so. This is server side php you can use any script you like to interact with the post variables.
if(isset($_FILES['video']['error'])){
$path = //path to store video
$file_name = $_FILES['video']['name'];
$file_size = $_FILES['video']['size'];
$file_type = $_FILES['video']['type'];
$temp_name = $_FILES['video']['tmp_name'];
if(move_uploaded_file($temp_name, $path.'/'.$file_name)){
$response =$path.'/'.$file_name;
}
}
The post variables will be retrieved usual methods $data=$_POST['data'];
If this code isn't working for files it would then be the result of something on your server. probably the file size. most hosted servers have restrictions on post size upload file size etc. Some will let you override that in your .htaccess. To debug the issue add an echo under if(isset in on server side to echo out the error code and the php manual has great explanations of what they mean. If it reads 1 then try to override php.ini in the .htaccess with something like this inside
php_value post_max_size 30M
php_value upload_max_filesize 30M

trouble in upload data android

i need to upload audio file(or any File) in server. i have asp.net server and refer this code but as per my doubt it is code of PHP server uploading.but i need to do in asp.net. so what is the changes to apply ?

To upload a file on server I don't think so for asp .net and PHP server have a different code on android.
Just check your server side script. For android both are treated as a server (either a asp .net or PHP).
I don't know PHP or asp .net but take a look at these examples,
How to upload a file using Java HttpClient library working with PHP - strange problem
HTTP Post multipart file upload in Java ME
Upload image using POST, php and Android
Java Swing File upload with Php on the server
http://www.tizag.com/phpT/fileupload.php
In these, there are some example for java swing or java ME but I think just use the logic for upload file from java and then take look at how they handle on server side with php script.
