Android Java file upload to Django backend

I have tried relentlessly to create a succesfull file upload from my JAVA/Android project to Django/Python backend.
The file I am trying to upload is a wav audio file which is stored on the phone.
I am trying to mix two sets of code.
The Android code I am using is the one taken from: How to upload a WAV file using URLConnection.
public class curlAudioToWatson extends AsyncTask<String, Void, String> {
String asrJsonString="";
#Override
protected String doInBackground(String... params) {
String result = "";
try {
Log.d("Msg","**** UPLOADING .WAV to ASR...");
URL obj = new URL(ASR_URL);
HttpURLConnection conn = (HttpURLConnection) obj.openConnection();
//conn.setRequestProperty("X-Arg", "AccessKey=3fvfg985-2830-07ce-e998-4e74df");
conn.setRequestProperty("Content-Type", "audio/wav");
conn.setRequestProperty("enctype", "multipart/form-data");
conn.setRequestMethod("POST");
conn.setDoInput(true);
conn.setDoOutput(true);
String wavpath=mRcordFilePath;
File wavfile = new File(wavpath);
boolean success = true;
if (wavfile.exists()) {
Log.d("Msg","**** audio.wav DETECTED: "+wavfile);
}
else{
Log.d("Msg","**** audio.wav MISSING: " +wavfile);
}
String charset="UTF-8";
String boundary = Long.toHexString(System.currentTimeMillis()); // Just generate some unique random value.
String CRLF = "\r\n"; // Line separator required by multipart/form-data.
OutputStream output=null;
PrintWriter writer=null;
try {
output = conn.getOutputStream();
writer = new PrintWriter(new OutputStreamWriter(output, charset), true);
byte [] music=new byte[(int) wavfile.length()];//size & length of the file
InputStream is = new FileInputStream (wavfile);
BufferedInputStream bis = new BufferedInputStream (is, 16000);
DataInputStream dis = new DataInputStream (bis); // Create a DataInputStream to read the audio data from the saved file
int i = 0;
copyStream(dis,output);
}
catch(Exception e){
}
conn.connect();
int responseCode = conn.getResponseCode();
Log.d("Msg","POST Response Code : " + responseCode + " , MSG: " + conn.getResponseMessage());
if (responseCode == HttpURLConnection.HTTP_OK) { //success
BufferedReader in = new BufferedReader(new InputStreamReader(conn.getInputStream()));
String inputLine;
StringBuffer response = new StringBuffer();
while ((inputLine = in.readLine()) != null) {
response.append(inputLine);
}
in.close();
Log.d("Msg","***ASR RESULT: " + response.toString());
JSONArray jresponse=new JSONObject(response.toString()).getJSONObject("Recognition").getJSONArray("NBest");
asrJsonString=jresponse.toString();
for(int i = 0 ; i < jresponse.length(); i++){

The Django backend code is taken from: https://simpleisbetterthancomplex.com/tutorial/2016/08/01/how-to-upload-files-with-django.html and I am using the simple upload:
def simple_upload(request):
if request.method == 'POST' and request.FILES['myfile']:
myfile = request.FILES['myfile']
fs = FileSystemStorage()
filename = fs.save(myfile.name, myfile)
uploaded_file_url = fs.url(filename)
return render(request, 'core/simple_upload.html', {
'uploaded_file_url': uploaded_file_url
})
return render(request, 'core/simple_upload.html')
I have already disabled the need for CSRF using #csrf_exempt.
I am getting the error "MultiValueDictKeyError" since Java does not post the file with the name 'myfile' for request.FILES['myfile'] to catch. Is have tried removing the ['myfile'] and just use request.FILES but then I get an error on
filename = fs.save(myfile.name, myfile)
saying there is no name to fetch.
Can I post the file so that it it catched by
request.FILES['myfile']
or is there better/simpler Django backend-code to use for communication with Android/IOS.
Thanks in advance and I apologize if this is a stupid question but I am dead stuck.

Here I go again answering my own question.
I found the following code from Android:How to upload .mp3 file to http server?
Using that instead of How to upload a WAV file using URLConnection and changing the line: dos.writeBytes("Content-Disposition: form-data; name=\"uploadedfile\";filename=\"" + existingFileName + "\"" + lineEnd);
To dos.writeBytes("Content-Disposition: form-data; name=\"myfile\";filename=\"" + existingFileName + "\"" + lineEnd);
fixed my problem.

Uploading Image to Server - Android

I have got the Rest Api's link and the sample code for uploading the image in C sharp but how to upload image to server from android the same thing using java
Here's that sample code
http://xx.xx.xxx.xx/restservice/photos
Sample code for uploading file:
string requestUrl = string.Format("{0}/UploadPhoto/{1}", url,filnm);
//file name should be uniqque
HttpWebRequest request = (HttpWebRequest)HttpWebRequest.Create(requestUrl);
request.Method = "POST";
request.ContentType = "text/plain";
byte[] fileToSend = FileUpload1.FileBytes; //File bytes
request.ContentLength = fileToSend.Length;
using (Stream requestStream = request.GetRequestStream())
{
// Send the file as body request.
requestStream.Write(fileToSend, 0, fileToSend.Length);
requestStream.Close();
}
using (HttpWebResponse response = (HttpWebResponse)request.GetResponse())
Console.WriteLine("HTTP/{0} {1} {2}", response.ProtocolVersion, (int)response.StatusCode, response.StatusDescription);
how you will you do it with the android
EDITED:

I am currently using this code to upload small videos to server (PHP server side).
Take not that the apache HttpClient is not supported anymore, so HttpURLConnection is the way to go.
try {

path));

connection = (HttpURLConnection) url.openConnection();
connection.setDoInput(true);
connection.setDoOutput(true);
connection.setUseCaches(false);
connection.setRequestMethod("POST");
connection.setRequestProperty("Connection", "Keep-Alive");
connection.setRequestProperty("Content-Type",
"multipart/form-data;boundary=" + boundary);
outputStream = new DataOutputStream(connection.getOutputStream());
outputStream.writeBytes(twoHyphens + boundary + lineEnd);
outputStream
.writeBytes("Content-Disposition: form-data; name=\"uploadedfile\";filename=\""
+ path + "\"" + lineEnd);
outputStream.writeBytes(lineEnd);
bytesAvailable = fileInputStream.available();
bufferSize = Math.min(bytesAvailable, maxBufferSize);
buffer = new byte[bufferSize];
bytesRead = fileInputStream.read(buffer, 0, bufferSize);
while (bytesRead > 0) {
outputStream.write(buffer, 0, bufferSize);
bytesAvailable = fileInputStream.available();
bufferSize = Math.min(bytesAvailable, maxBufferSize);
bytesRead = fileInputStream.read(buffer, 0, bufferSize);
}
outputStream.writeBytes(lineEnd);
outputStream.writeBytes(twoHyphens + boundary + twoHyphens
+ lineEnd);
fileInputStream.close();
outputStream.flush();
outputStream.close();
InputStream responseStream = new BufferedInputStream(connection.getInputStream());
BufferedReader responseStreamReader = new BufferedReader(new InputStreamReader(responseStream));
String line = "";

Android post file array

I have tried to post multiple file to web service. But, single file post working multiple file post not working.
Please help me any one. How to implement that feature.
I have tried the below code. Please check it.

String boundary = "*****";
int bytesRead, bytesAvailable, bufferSize;
byte[] buffer;
int maxBufferSize = 1 * 1024 * 1024;
File sourceFile = new File(sourceFileUri);
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);
}
});
return 0;
} else {
try {
// open a URL connection to the Servlet
URL url = new URL(upLoadServerUri);
// Open a HTTP connection to the URL
conn = (HttpURLConnection) url.openConnection();
conn.setDoInput(true); // Allow Inputs

dos.writeBytes(lineEnd);
FileInputStream fileInputStream = new FileInputStream(
sourceFile);
// create a buffer of maximum size
bytesAvailable = fileInputStream.available();
bufferSize = Math.min(bytesAvailable, maxBufferSize);
buffer = new byte[bufferSize];
// read file and write it into form...

bytesRead = fileInputStream.read(buffer, 0, bufferSize);
}
// send multipart form data necesssary after file data...
dos.writeBytes(lineEnd);
dos.writeBytes(twoHyphens + boundary + twoHyphens + lineEnd);
// Responses from the server (code and message)
serverResponseCode = conn.getResponseCode();
String serverResponseMessage = conn.getResponseMessage();
Log.i("uploadFile", "HTTP Response is : "

// close the streams //
fileInputStream.close();
dos.flush();
dos.close();
InputStream is = conn.getInputStream();
// retrieve the response from server
int ch;
StringBuffer b = new StringBuffer();
while ((ch = is.read()) != -1) {
b.append((char) ch);
}
String s = b.toString();
Log.i("Response", s);
} catch (MalformedURLException ex) {
dialog.dismiss();
ex.printStackTrace();
runOnUiThread(new Runnable() {
public void run() {
messageText
.setText("MalformedURLException Exception : check script url.");
Toast.makeText(MainActivity.this,
"MalformedURLException", Toast.LENGTH_SHORT)
.show();
}
});
Log.e("Upload file to server", "error: " + ex.getMessage(), ex);
} catch (Exception e) {
dialog.dismiss();
e.printStackTrace();
runOnUiThread(new Runnable() {
public void run() {
messageText.setText("Got Exception : see logcat ");
Toast.makeText(MainActivity.this,

Toast.LENGTH_SHORT).show();
}
});
Log.e("Upload file to server Exception",
"Exception : " + e.getMessage(), e);
}
dialog.dismiss();
return serverResponseCode;
}

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();
}

How to send file through http post method without additional info?

I am sending a file from sd card by using the following code.
HttpURLConnection conn = null;
DataOutputStream dos = null;

String responseFromServer = "";
String urlString = "http://192.178.1.7/Geo/Prodect(filename)";
try

}
inStream.close();
}
catch (IOException ioex)
{

}
It works fine but,the file contains 20 lines it saved in the sever with 22 lines.
My actual file looks like as follows.
android app info
app name
app time
when i will send the flle to server from sd card the file look like as follows
1)**mnt/sdcard/111**
android app info
app name
app time
2)**
1 and 2 lines are added.
How i can send a file without those two lines .
If any one know the solution please help me .
Thanks in advance..

Please reference to above simple code,
send file like this:post("http://youurl.com",new FileInputStream(" you file path"))

Try commenting the following

dos.writeBytes(lineEnd);

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))

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
