android upload large images

I want to create an app to upload large images (captured with smartphone so the size is over 3MB) to PHP server and a database with the path of the image. I have followed this tutorial with volley library https://www.simplifiedcoding.net/upload-image-to-server/
But I want to have two different buttons. One for selecting an image and another for uploading it. I know that I'm doing something wrong. Bcause it gives me null bitmap. I don't know what I have to change.

May be because in php the max size u can send is 2Mg, try te send a picture less then 2M , if it's work you have to go to php.ini and thange the max_size

i use this code for uploading files and i've not faced problems for uploading files over 14MB.
HttpURLConnection conn = null;
DataOutputStream dos = null;
String boundary = "*****";
int bytesRead, bytesAvailable, bufferSize;
byte[] buffer;
int maxBufferSize = 1 * 1024;
final File sourceFile = file_to_upload;
String serverResponseMessage;
String response = null;
if (!sourceFile.isFile()) {
return "no file";
} else {
try {
FileInputStream fileInputStream =
new FileInputStream(sourceFile.getPath());
URL url = "upload_URL";
conn = (HttpURLConnection) url.openConnection();
int size = (int) sourceFile.length();
conn.setFixedLengthStreamingMode(size);
conn.setDoInput(true); // Allow Inputs
conn.setDoOutput(true); // Allow Outputs
conn.setUseCaches(false); // Don't use a Cached Copy
conn.setRequestMethod("POST");
conn.setRequestProperty("Connection", "Keep-Alive");
conn.setRequestProperty("ENCTYPE", "multipart/form-data");
conn.setRequestProperty("Content-Type", "multipart/form-data;boundary=" + boundary);
dos = new DataOutputStream(conn.getOutputStream());
bytesAvailable = fileInputStream.available();
bufferSize = Math.min(bytesAvailable, maxBufferSize);
buffer = new byte[bufferSize];
bytesRead = 0;

Log.e("start", "" + size);
do {

dos.write(buffer, 0, bufferSize);
total_bytes += bytesRead;
float f1 = total_bytes;
float f2 = size;
float f3 = f1 / f2;
publishProgress(f3);
} while (bytesRead > 0);
int serverResponseCode = conn.getResponseCode();

How to post data using multipart?

I develop one app. In my app i take one image from camera or one from gallery. I want to post image to server using Multipart but image not post it. My post data is below
{
"suggested_item" :{
"name": "apple",
"description" : "nice apple",
"image": "image.png"
}
}
My java code is
public void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == PICK_FROM_CAMERA) {
try{
if(resultCode == -1){
File file = new File(Environment.getExternalStorageDirectory()+File.separator +"image.png");
bitmap = loadBitmap(file);
iv_pic.setImageBitmap(bitmap);
try {
Uri tempUri = getImageUri(getActivity(), bitmap);
Log.i(TAG,"onActivityResult PICK_FROM_CAMERA, tempUri : "+tempUri);
//uploadFile(tempUri + "" + System.currentTimeMillis()+".png");
} catch (Exception e) {
e.printStackTrace();
}
}else{
//setResult(RESULT_CANCELED);
//Activity.this.finish();
}
}catch(Exception e){
e.printStackTrace();
}
}else if (requestCode == PICK_FROM_GALLERY) {
try{
//Log.i(TAG,"onActivityResult PICK_FROM_GALLERY, data : "+data);
if(data !=null){
bitmap = null;
try {
bitmap = new BitmapDrawable(MediaStore.Images.Media.getBitmap(getActivity().getContentResolver(), data.getData())).getBitmap();
iv_pic.setImageBitmap(bitmap);
try {
Uri tempUri = getImageUri(getActivity(), bitmap);
Log.i(TAG,"onActivityResult PICK_FROM_GALLERY, tempUri : "+tempUri);
//uploadFile(tempUri + "" + System.currentTimeMillis()+".png");
} catch (Exception e) {
e.printStackTrace();
}
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}else{
//setResult(RESULT_CANCELED);
//Activity.this.finish();
}
}catch(Exception e){
e.printStackTrace();
}
}
}
public Uri getImageUri(Context context , Bitmap bitmap) {
ByteArrayOutputStream bytes = new ByteArrayOutputStream();
bitmap.compress(Bitmap.CompressFormat.JPEG , 100 , bytes);
String path = Images.Media.insertImage(context.getContentResolver() , bitmap , "Title" , null);
return Uri.parse(path);
}
please help me thanks in advance.

To send binary data you need to use addBinaryBody method of MultipartEntityBuilder. Sample of attaching:
import org.apache.http.entity.ContentType;
import org.apache.http.entity.mime.MultipartEntityBuilder;
//Image attaching
MultipartEntityBuilder multipartEntity = MultipartEntityBuilder.create();
File file;
multipartEntity.addBinaryBody("someName", file, ContentType.create("image/jpeg"), file.getName());
//Json string attaching
String json;
multipartEntity.addPart("someName", new StringBody(json, ContentType.TEXT_PLAIN));
Then make request as usual:
HttpPut put = new HttpPut("url");
put.setEntity(multipartEntity.build());
HttpResponse response = client.execute(put);
int statusCode = response.getStatusLine().getStatusCode();

I suggest using retrofit.
Posting multipart will be something like this:
#Multipart
#PUT("user/photo")
Call<User> updateUser(#Part("photo") RequestBody photo, #Part("description") RequestBody description);
Refer to this question for more details.
This is a good tutorial to check if you are not familiar to retrofit.

MultipartEntity multipartEntity = new MultipartEntity(HttpMultipartMode.BROWSER_COMPATIBLE);
multipartEntity.addPart("key", new StringBody("file"));
File file = new File(selectedImagePath);
multipartEntity.addPart("file", new FileBody(file));
httppost.setEntity(multipartEntity);
mHttpClient.execute(httppost, new PhotoUploadResponseHandler());
and the response methode:
private class PhotoUploadResponseHandler implements ResponseHandler<Object> {
#Override
public Object handleResponse(HttpResponse response)
throws ClientProtocolException, IOException {
HttpEntity r_entity = response.getEntity();
// String responseString = EntityUtils.toString(r_entity);
return null;
}
}

Use multipart in android, download httpmime-4.2.5.jar and add you libs folder http://grepcode.com/snapshot/repo1.maven.org/maven2/org.apache.httpcomponents/httpmime/4.2.5
HttpClient httpclient = new DefaultHttpClient();
httpclient.getParams().setParameter(CoreProtocolPNames.PROTOCOL_VERSION, HttpVersion.HTTP_1_1);
HttpPost httppost = new HttpPost("url");
File file = new File(filepath);
MultipartEntity mpEntity = new MultipartEntity();
ContentBody cbFile = new FileBody(file, "image/jpeg");
mpEntity.addPart("userfile", cbFile);
httppost.setEntity(mpEntity);
System.out.println("executing request " + httppost.getRequestLine());
HttpResponse response = httpclient.execute(httppost);
HttpEntity resEntity = response.getEntity();

try this code..
String url = "";
MultiValueMap<String, Object> parts = new LinkedMultiValueMap<String, Object>();
parts.add("file", new FileSystemResource(your filename path));
RestTemplate rest = RestUtil.getRestTemplate();
rest.postForObject(url, parts, returnclassname.class);
return null;
thank you..

The server side code remains the same for both browser based and mobile apps, to upload an file. File upload requires a multipart post request.
Uploading an image is same as uploading a file with a specified content type image/*. You can mimic the request using Apache's HttpClient. Also remember to perform the upload in the separate thread.
Here's an example.

Please check your android manifest file. Have u allowed all these in your manifest.?
Sorry I m missing some permissions please google them.
<uses-permission android:name="android.permission.CAMERA" />
<uses-feature android:name="android.hardware.camera" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

Android upload file to .NET web server

I want to write an android app that can upload a file to a c sharp base web server.
So far I have no luck. I kept getting Address family not supported by protocol.
I've added INTERNET and WRITE_EXTERNAL_STORAGE in my manifest file.
Keep in mind that I run this in emulator.
Any idea or suggestion is really appreciated.
Thank you in advance
