i am trying to upload a image to server from an android phone. this is what i have done so far
OkHttpClient client = new OkHttpClient();
MultipartBuilder builder = new MultipartBuilder();
builder.type(MultipartBuilder.FORM).addPart(RequestBody.create(MediaType.parse("application/json; charset=utf-8"), requestPackage.getJsonParam().toString()));
for (int i = 0; i < requestPackage.getPics().size(); i++) {
builder.addPart(RequestBody.create(MediaType.parse("image/png"/* + i*/), new File(URI.create(requestPackage.getPics().get(i)))));
Log.i("image to upload",URI.create(requestPackage.getPics().get(i)).toString());
}
requestBody = builder.build();
Request request = new Request.Builder().url(requestPackage.getUri()).post(requestBody).build();
try {
response = client.newCall(request).execute();
if (!response.isSuccessful()) throw new IOException("Unexpected code " + response);
// System.out.println(response.body().string());
return response.body().string();
} catch (IOException e) {
e.printStackTrace();
}
how do i add names to the different parts.because if there is no name(key) to them then how will server side guy store it?
Get OkHttp 2.1, and use MultipartBuilder.addFormDataPart() which takes the filename as a parameter.
The syntax seems to have changed a bit since the previous answers. I'm using OkHttp 3.2.0.
public void upload(String url, File file) throws IOException {
RequestBody formBody = new MultipartBody.Builder()
.setType(MultipartBody.FORM)
.addFormDataPart("file", file.getName(),
RequestBody.create(MediaType.parse("image/png"), file))
.addFormDataPart("other_field", "other_field_value")
.build();
Request request = new Request.Builder().url(url).post(formBody).build();
Response response = this.client.newCall(request).execute();
}
You can find all in the official document: https://github.com/square/okhttp/wiki/Recipes
Especially you will be interested in folowing piece from Posting a multipart request:
RequestBody requestBody = new MultipartBuilder()
.type(MultipartBuilder.FORM)
.addPart(
Headers.of("Content-Disposition", "form-data; name=\"title\""),
RequestBody.create(null, "Square Logo"))
.addPart(
Headers.of("Content-Disposition", "form-data; name=\"image\""),
RequestBody.create(MEDIA_TYPE_PNG, new File("website/static/logo-square.png")))
.build();
Here is a complete solution, of how to upload a file using okhttp3.
Firstly, add a file picker with a button on click listener to your code like this:
A button to pick file:
#Override
public void onClick(View v) {
switch (v.getId()) {
case R.id.btn_choose_file:
showFileChooser();
break;
}
}
private String filePath = null;
private File sourceFile;
private static final int FILE_SELECT_CODE = 0;
private void showFileChooser() {
Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
intent.setType("*/*");
intent.addCategory(Intent.CATEGORY_OPENABLE);
try {
startActivityForResult(
Intent.createChooser(intent, "Select a File to Upload"),
FILE_SELECT_CODE);
} catch (android.content.ActivityNotFoundException ex) {
Toast.makeText(this, "Please install a File Manager.",
Toast.LENGTH_SHORT).show();
}
}
Then handle onActivityResult like this:
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
switch (requestCode) {
case FILE_SELECT_CODE:
if (resultCode == RESULT_OK) {
// Get the Uri of the selected file
Uri uri = data.getData();
File file = new File(getCacheDir(), getFileName(uri));
int maxBufferSize = 1 * 1024 * 1024;
try {
InputStream inputStream = getContentResolver().openInputStream(uri);
Log.e("InputStream Size","Size " + inputStream);
int bytesAvailable = inputStream.available();
int bufferSize = Math.min(bytesAvailable, maxBufferSize);
final byte[] buffers = new byte[bufferSize];
FileOutputStream outputStream = new FileOutputStream(file);
int read = 0;
while ((read = inputStream.read(buffers)) != -1) {
outputStream.write(buffers, 0, read);
}
Log.e("File Size","Size " + file.length());
inputStream.close();
outputStream.close();
file.getPath();
Log.e("File Path","Path " + file.getPath());
file.length();
Log.e("File Size","Size " + file.length());
if(file.length() > 0){
sourceFile = file;
filePath = sourceFile.getPath();
}
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
} catch (OutOfMemoryError e) {
e.printStackTrace();
}
} else {
}
break;
}
super.onActivityResult(requestCode, resultCode, data);
}
private String getMimeType(String path) {
FileNameMap fileNameMap = URLConnection.getFileNameMap();
String contentTypeFor = fileNameMap.getContentTypeFor(path);
if (contentTypeFor == null)
{
contentTypeFor = "application/octet-stream";
}
return contentTypeFor;
}
public String getFileName(Uri uri) {
String result = null;
if (uri.getScheme().equals("content")) {
Cursor cursor = getContentResolver().query(uri, null, null, null, null);
try {
if (cursor != null && cursor.moveToFirst()) {
result = cursor.getString(cursor.getColumnIndex(OpenableColumns.DISPLAY_NAME));
}
} finally {
cursor.close();
}
}
if (result == null) {
result = uri.getPath();
int cut = result.lastIndexOf('/');
if (cut != -1) {
result = result.substring(cut + 1);
}
}
return result;
}
Finally, handle the file upload along with other needed information like this :
try {
UpdateInformation("yourEmailAddress", filePath, sourceFile);
} catch (IOException e) {
e.printStackTrace();
}
private void UploadInformation(String email, final String _filePath, final File file) throws IOException {
runOnUiThread(new Runnable() {
#Override
public void run() {
//show progress bar here
}
});
OkHttpClient client = new OkHttpClient.Builder()
.connectTimeout(60, TimeUnit.SECONDS)
.writeTimeout(60, TimeUnit.SECONDS)
.readTimeout(60, TimeUnit.SECONDS)
.build();
String mime = getMimeType(_filePath);
RequestBody body = new MultipartBody.Builder().setType(MultipartBody.FORM)
.addFormDataPart("file", file.getName(),
RequestBody.create(MediaType.parse(mime), file))
.addFormDataPart("email", email)
.build();
okhttp3.Request request = new okhttp3.Request.Builder()
.url("yourEndPointURL")
.post(body)
.addHeader("authorization", "yourEndPointToken")
.addHeader("content-type", "application/json")
.build();
client.newCall(request).enqueue(new Callback() {
#Override
public void onFailure(Call call, IOException e) {
call.cancel();
runOnUiThread(new Runnable() {
#Override
public void run() {
//hide progress bar here
}
});
}
#Override
public void onResponse(Call call, okhttp3.Response response) throws IOException {
try {
final String myResponse = response.body().string();
runOnUiThread(new Runnable() {
#Override
public void run() {
//hide progress bar here
//Cont from here
//Handle yourEndPoint Response.
}
});
} catch (Exception e) {
e.printStackTrace();
}
}
});
}
Note: Don't forget to add this permission to the manifest file.
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
You can use multipart like below to send multiple values in single request
HttpPost httppost = new HttpPost(mPostURL);
MultipartEntity entity = new MultipartEntity();
entity.addPart("value", new StringBody("upload", Charset.forName("UTF-8")));
File myFile = new File(mFilePath);
FileBody fileBody = new FileBody(filePath);
entity.addPart("file", fileBody);
entity.addPart("filename", new StringBody("fileName", Charset.forName("UTF-8")));
httppost.setEntity(entity);
HttpClient httpClient = new DefaultHttpClient();

I tried to upload a large file to a server (the max file size supported is 128Mb). If I correctly understood, the server can receive large files (for example 500Mb) but only if these files are sent in chunks.
I wrote the method bellow and expected it to upload video files in chunks to the server. However, I am getting the following error from the server:
413 Request Entity Too Large
Bellow is my method:
public static void uploadFile(Context context, Uri videoUri, String fileName, File file) throws FileNotFoundException {
int CHUNK_SIZE = 2048;
ContentResolver contentResolver = context.getContentResolver();
final String contentType = contentResolver.getType(videoUri);
final AssetFileDescriptor fd = contentResolver.openAssetFileDescriptor(videoUri, "r");
if (fd == null) {
try {
throw new FileNotFoundException("could not open file descriptor");
} catch (FileNotFoundException e) {
e.printStackTrace();
}
}
RequestBody videoFile = new RequestBody() {
#Override
public long contentLength() {
return fd.getDeclaredLength();
}
#Override
public MediaType contentType() {
return MediaType.parse(contentType);
}
#Override
public void writeTo(BufferedSink sink) throws IOException {
Source source = null;
try {
source = Okio.source(file);
long total = 0;
long read;
while ((read = source.read(sink.buffer(), CHUNK_SIZE)) != -1) {
total += read;
sink.flush();
Log.e("progress", String.valueOf(total/100/100/100));
//this.listener.transferred(total);
}
} finally {
Util.closeQuietly(source);
}
}
};
RequestBody requestBody = new MultipartBody.Builder()
.setType(MultipartBody.FORM)
.addFormDataPart("video/*", fileName, videoFile)
.build();
Request request = new Request.Builder()
.url("https://test.ua/api/upload")
.post(requestBody)
.header("Authorization", Utils.getHeaderToken())
.build();
OkHttpClient client = new OkHttpClient.Builder().build();
client.newCall(request).enqueue(new Callback() {
#Override public void onFailure(Call call, IOException e) {
try {
fd.close();
} catch (IOException ex) {
e.addSuppressed(ex);
}
Log.e("asdasd", "failed", e);
}
#Override public void onResponse(Call call, Response response) throws IOException {
Log.e("success", String.valueOf(response.code()));
InputStream in = response.body().byteStream();
BufferedReader reader = new BufferedReader(new InputStreamReader(in));
String result, line = reader.readLine();
result = line;
while((line = reader.readLine()) != null) {
result += line;
}
Log.e("success", String.valueOf(result));
fd.close();
}
});
}
UPD:
server use laravel-chunk-upload and they have this settings in frontend:
dropzoneOptions: {
url: '/upload',
dictDefaultMessage: 'Click here',
chunksUploaded: function (file, done) {
done()
},
thumbnailWidth: 150,
maxFilesize: 250,
chunking: false,
chunkSize: 1000000, // Bytes
required: true,
maxFiles: 1,
acceptedFiles: 'video/*',
headers: {
'X-CSRF-TOKEN': $('meta[name="csrf-token"]').attr('content')
}
},
I am using OkHttp to download a file from the server.
And this is my code:
I set read and write timeout for it:
public static final String API_BASE_URL = "http://XXXX:8080/tablet/";
private static OkHttpClient.Builder httpClient = new OkHttpClient.Builder()
.connectTimeout(60,TimeUnit.SECONDS)
.writeTimeout(60,TimeUnit.SECONDS);
This is my createServiceFile:
public static <S> S createServiceFile(Class<S> serviceClass, final String token) {
if (token != null) {
httpClient.addInterceptor(new Interceptor() {
#Override
public Response intercept(Chain chain) throws IOException {
Request original = chain.request();
Request.Builder requestBuilder = original.newBuilder()
.header("Authorization", token)
.header("Accept", "text/html,application/xhtml+xml,application/pdf,application/xml;q=0.9," +
"image/webp,audio/mpeg ,image/png,audio/mp4,image/jpeg,*/*;q=0.8")
.method(original.method(), original.body());
Request request = requestBuilder.build();
return chain.proceed(request);
}
});
}
OkHttpClient client = httpClient.build();
Retrofit retrofit = builder.client(client).build();
return retrofit.create(serviceClass);
}
And this is my code that I write the response to SD Card (in response contentLength is -1 because the server doesn't send it to me):
public DownloadRequest DownloadFile() {
//Creating folder for Application in SD Card if it's not created yet in App Class!
new java.io.File(G.DIR_APP).mkdirs();
new java.io.File(G.DIR_MEDIA).mkdirs();
APIService downloadService = ServiceGenerator.createServiceFile(APIService.class, G.TOKEN);
downloadService.downloadFileWithDynamicUrlSync(url)//set URL of the file
.subscribeOn(Schedulers.newThread())
.observeOn(Schedulers.io())
.delay(30, TimeUnit.MILLISECONDS)
.subscribe(new Observer<ResponseBody>() {
#Override
public void onSubscribe(Disposable d) {
}
#Override
public void onNext(ResponseBody responseBody) {
Log.i(TAG, "On Next And Current App is: " + fileName);
if (writeResponseBodyToDisk(responseBody)) {
Log.i(TAG, fileName + "Downloaded successful");
//This Download was successful Then try to set downloadResult true
result = true;
} else {
result = false;
}
}
#Override
public void onError(Throwable e) {
Log.i(TAG, "!!!!!!!!!!!!!!!!\n\nOn Error And Current App is: " +
fileName + " And Error is" + e.toString() + "\n\n!!!!!!!!!!!!!!!!\n\n");
//Set downloadResult false
result = false;
if (listener != null) {
listener.onDownloadCompleteListener(false);
}
}
#Override
public void onComplete() {
Log.i(TAG, "On Complete And Current App is: " + fileName);
if (listener != null) {
if (result) {
listener.onDownloadCompleteListener(true);
} else {
listener.onDownloadCompleteListener(false);
}
}
}
});
return this;
}
And this code will write response to disck:
private boolean writeResponseBodyToDisk(ResponseBody body) {
// Location to save downloaded file and filename
java.io.File file = new java.io.File(destinationPath + fileName + "." + extension);
try {
InputStream inputStream = null;
OutputStream outputStream = null;
int bytesBuffered = 0;
try {
byte[] fileReader = new byte[bufferSize];
downloadSize = 0;
inputStream = body.byteStream();
/*
* If append requested we have to append new bytes to
* Exists bytes on the storage
*/
if (appendNeed) {
outputStream = new FileOutputStream(file, true);
} else {
outputStream = new FileOutputStream(file);
}
while (true) {
int read = inputStream.read(fileReader);
if (read == -1) {
break;
}
bytesBuffered += read;
if (bytesBuffered > 1024 * 1024) {
// outputStream.write(fileReader, 0, read);
outputStream.flush();
bytesBuffered = 0;
}
outputStream.write(fileReader, 0, read);
downloadSize += read;
percent = (int) (100.0f * (float) downloadSize / totalSize);
if (listener != null) {
listener.onDownloadPercentListener(percent);
}
}
outputStream.flush();
inputStream.close();
outputStream.close();
return true;
} catch (IOException e) {
Log.i(TAG, "Error in download" + e.toString());
return false;
} finally {
if (inputStream != null) {
inputStream.close();
}
if (outputStream != null) {
outputStream.close();
}
}
} catch (IOException e) {
Log.i(TAG, "Error in download" + e.toString());
return false;
}
}
But I get false from this method (writeResponseBodyToDisk)with error of
java.net.SocketTimeoutException while the file is downloaded correctly!
I think this problem it about contentLength that is -1 for me.
Thank you for your answers.
I am working on an app in which I want to get image from gallery or camera and then send it to server using multipart. I am able to send picture from gallery to server but when I tried to send image from camera it shows me failure.

As per comments :
Get image from gallery or camera like this :
File mainFile = null;
Bitmap bitmap = (Bitmap) data.getExtras().get("data");
String partFilename = currentDateFormat();
mainFile = storeCameraPhotoInSDCard(bitmap, partFilename);
public String currentDateFormat() {
String currentTimeStamp = null;
try {
SimpleDateFormat dateFormat = new SimpleDateFormat("yyyyMMdd_HH_mm_ss");
currentTimeStamp = dateFormat.format(new Date());
} catch (Exception e) {
e.printStackTrace();
}
return currentTimeStamp;
}
public File storeCameraPhotoInSDCard(Bitmap bitmap, String currentDate) {
File outputFile = new File(Environment.getExternalStorageDirectory(), "photo_" + currentDate + ".jpg");
try {
FileOutputStream fileOutputStream = new FileOutputStream(outputFile);
bitmap.compress(Bitmap.CompressFormat.JPEG, 100, fileOutputStream);
fileOutputStream.flush();
fileOutputStream.close();
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
return outputFile;
}
Use mainFile to send in RequestBody and pass like execMultipartPost(File file)

I am also getting the error:

Can someone tell me how to implement it correctly.
Use URL with domain name to download file.Remove streaming annotation don't need that.
You are not receiving file body as you are not using complete URL.
Create an interface like this
#GET
Call<ResponseBody> downloadFile(#Url String url);
Then use this code :
public void onResponse(Call<ResponseBody> call, Response<ResponseBody>
response)
{
if (response.isSuccessful()) {
String filePath = Utils.downloadFile(response.body(),"filename");
}
}
public String downloadFile(ResponseBody body, String fileName) {

I want to upload list of files (images in my case) from JBoss server to android.
I am doing so by the below written code:
#GET
#Path("/report/{filename}")
#Produces({MediaType.MULTIPART_FORM_DATA})
public MultipartFormDataOutput getReport(#PathParam("filename") String filename, #Context HttpServletRequest request) {
try {
String token = request.getHeader("Authorization");
List<File> file = processImage.getImage(filename,token);
MultipartFormDataOutput output = new MultipartFormDataOutput();
for(File image: file){
System.out.println("class of this" +image + "MMMM" +image.exists());
output.addPart(image, new MediaType("image","jpg"));
}
return output;
} .....
.......
}
On Android side I want to read the response (the files in multipart form). I am using okHttp to make the connection.
Searching a lot on internet I tried the below code to read the multipart response, but it is not working. It seems that is not reading anything from the stream.
ByteArrayDataSource ds = new ByteArrayDataSource(response.body().byteStream(), "multipart/form-data");
MimeMultipart multipart = new MimeMultipart(ds);
BodyPart jsonPart = multipart.getBodyPart(0);
System.out.println("Response body = " + jsonPart.getInputStream());
File reportFile = new File(Environment.getExternalStorageDirectory() + File.separator + "downloadedFile.jpg");
InputStream is = jsonPart.getInputStream();
FileOutputStream fileOutputStream = null;
try {
fileOutputStream = new FileOutputStream(reportFile);
byte[] buffer = new byte[MEGABYTE];
int bufferLength = 0;
while ((bufferLength = is.read(buffer)) > 0) {
fileOutputStream.write(buffer, 0, bufferLength);
}
is.close();
fileOutputStream.close();
.......
}
Can anyone please help me solving this. I am stuck here from 2 days. What am I doing wrong .
You can do the following:
Create an async task to run in the background
Use okhttp3.Request to create the request
Create OkHttpClient to send the request and save the response in okHttp3 Response
Then get the response body from the okhttp3.ResponseBody and use InputStreamReader and BufferedReader to read the files.
Something like following should work:
private class FileTask extends AsyncTask<Void, Void, Void> {
private File file = null;
#Override
protected Void doInBackground(Void... params) {
okhttp3.Request request = new okhttp3.Request.Builder()
.url("Your URL for getReport()")
.get()
.build();
OkHttpClient okHttpClient = new OkHttpClient.Builder().
connectTimeout(80, TimeUnit.SECONDS)
.writeTimeout(80, TimeUnit.SECONDS)
.readTimeout(80, TimeUnit.SECONDS)
.build();
try {
Response response = okHttpClient.newCall(request).execute();
okhttp3.ResponseBody in = response.body();
InputStream is = in.byteStream();
InputStreamReader inputStreamReader = new InputStreamReader(is);
BufferedReader buffReader = new BufferedReader(inputStreamReader);
file = new File(Environment.getExternalStorageDirectory() + File.separator + "filename.txt"); //Your output file
OutputStream output = new FileOutputStream(file);
BufferedOutputStream bufferedOutputStream = new BufferedOutputStream(output);
String line=buffReader.readLine();
while ((line=buffReader.readLine()) != null) {
output.write(line.getBytes());
output.write('\n');
}
buffReader.close();
output.close();
} catch (Exception e) {
e.printStackTrace();
}
return null;
}
#Override
protected void onPostExecute(Void aVoid) {
//do post execution steps
}
}
}
Are you possibly using HttpLoggingInterceptor with setLevel(HttpLoggingInterceptor.Level.BODY)? I used your code to successfully parse a multipart response. But once I change the level from HEADERS to BODY, that code no longer works, and acts as if it is not reading anything from the stream. I already reported the issue: https://github.com/square/okhttp/issues/3269
By the way, thanks for giving me sample code to allow me to parse a multipart body with OkHttp. For others who may come along, I had to add this to my maven pom.xml:
<dependency>
<groupId>com.sun.mail</groupId>
<artifactId>javax.mail</artifactId>
<version>1.5.6</version>
</dependency>
try this:
//first you should convert image into bytearray
VolleyMultipartRequest multipartRequest = new VolleyMultipartRequest(Request.Method.POST, url, new Response.Listener<NetworkResponse>() {
#Override
public void onResponse(NetworkResponse response) {
System.out.println(" response"+response.data);
String resultResponse = new String(response.data);
System.out.println("------------- response-----------------"+resultResponse);
try {
JSONObject jsonObject = new JSONObject(resultResponse);
sStatus = jsonObject.getString("status");
} else {
}
} catch (JSONException e) {
e.printStackTrace();
