Posting image to apache server by multipart-data requests via urlConnection Android app,server response 0 files found.

Since the Android developers recommend to use the HttpURLConnection
class, I was wondering if anyone can provide me with a good example on
how to send a bitmap "file" (actually an in-memory stream) via POST to
an Apache HTTP server. I'm not interested in cookies or authentication
or anything complicated, but I just want to have a reliable and logic
implementation. All the examples that I've seen around here look more
like "let's try this and maybe it works".
posting image to apache server multipart-data request
via urlConnection
opening image as a fileinputStream
then posting image to server
server replies 0 files found
there is my example function

String serverResponseJsonStr = null;

File path = cw.getDir("imageDir", Context.MODE_PRIVATE);
//File path1 = cw.getFileStreamPath("user photos");
Log.i("check file path",cw.getFileStreamPath("user photos").toString());
//cheking if profile picture changed send it to server
if (isProfileImageChanged){
temp_file=new File(path+PROFILE_IMAGE_FOLDER, "profile");

If you want to pass an array of FileBody, you can try it like,
reqEntity.addPart("file[]["+i+"]", bab);
This will generate params like
file=>[{"1" => "File" },{"2" => "File"}..]
Hope it clarifies your doubt.

I got solution. I have used like as below. It's working.
public void uploadFileNew(ArrayList<String>IMAGEPTHLIST, ArrayList<String>IMAGENAMELIST) {
try {
HttpClient httpClient = new DefaultHttpClient();
HttpPost postRequest = new HttpPost(upLoadServerUri);
ByteArrayBody bab;
ByteArrayOutputStream bos;
Bitmap bm;
MultipartEntity reqEntity = new MultipartEntity(HttpMultipartMode.BROWSER_COMPATIBLE);
for(int i = 0 ; i< IMAGEPTHLIST.size() ; i++) {
bm = BitmapFactory.decodeFile(IMAGEPTHLIST.get(i));
bos = new ByteArrayOutputStream();
bm.compress(CompressFormat.PNG, 100, bos);
byte[] data = bos.toByteArray();
bab = new ByteArrayBody(data, IMAGENAMELIST.get(i));
reqEntity.addPart("file["+i+"]", bab);
}
reqEntity.addPart("cat_id", new StringBody("123"));
reqEntity.addPart("name", new StringBody("Android test"));
postRequest.setEntity(reqEntity);
HttpResponse response2 = httpClient.execute(postRequest);
BufferedReader reader = new BufferedReader(new InputStreamReader(response2.getEntity().getContent(), "UTF-8"));
String sResponse;
StringBuilder s = new StringBuilder();
while ((sResponse = reader.readLine()) != null) {
s = s.append(sResponse);
}
System.out.println("===="+s.toString());
} catch (Exception e) {
e.printStackTrace();
}
dialog.dismiss();
}

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 {
JSONObject response = null;
writer.append(LINE_FEED).flush();
writer.append("--" + boundary + "--").append(LINE_FEED);
writer.close();
String line;

while ((line=br.readLine()) != null) {
sb.append(line);
response =new JSONObject(sb.toString());
}
br.close();
return response;
}
public JSONArray finnishJARRAY()throws IOException, JSONException {
JSONArray response = null;
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"));

}
br.close();
return response;
}
public void finnishNoResponse(){
writer.append(LINE_FEED).flush();
writer.append("--" + boundary + "--").append(LINE_FEED);
writer.close();
}
}
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
