I would like to send a file to a server. Currently the code I use includes deprecated classes. How can I update the code to be uptodate?
protected String doInBackground(String... params) {
File file = new File(Environment.getExternalStorageDirectory().getAbsolutePath(), params[0]);
try {
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost(server);
InputStreamEntity reqEntity = new InputStreamEntity(new FileInputStream(file), -1);
reqEntity.setContentType("binary/octet-stream");
reqEntity.setChunked(true); // Send in multiple parts if needed
httppost.setEntity(reqEntity);
HttpResponse response = httpclient.execute(httppost);
//Do something with response...
} catch (Exception e) {
e.printStackTrace();
}
return null;
}
I suggest you to use this library : retrofit
http://square.github.io/retrofit/
I use it on my project right now and it helps me a lot with my http requests.
Moreover the documentation is really good.

I'm trying to upload images to my rails server from Android. All my other data uploads, but I get a "Error invalid body size" error. It has to do with the image. Below is my code. Help?!
public void post(String url) {
HttpClient httpClient = new DefaultHttpClient();
HttpContext localContext = new BasicHttpContext();
HttpPost httpPost = new HttpPost(url);
httpPost.addHeader("content_type","image/jpeg");
try {
MultipartEntity entity = new MultipartEntity(HttpMultipartMode.BROWSER_COMPATIBLE);
entity.addPart("picture_file_name", new StringBody("damage.jpg"));
File file = new File((imageUri.toString()));
entity.addPart("picture", new FileBody(file, "image/jpeg"));
httpPost.setEntity(entity);
HttpResponse response = httpClient.execute(httpPost, localContext);
} catch (IOException e) {
e.printStackTrace();
}
}
I've tried removing the browser compatible parameter, but it doesn't help. my image is being stored as an URI called imageUri. I'm using paperclip gem.
thanks!
This is how I solved.
MultipartEntity multipartEntity = new MultipartEntity(HttpMultipartMode.BROWSER_COMPATIBLE);
for (NameValuePair nameValuePair : nameValuePairs) {
if (nameValuePair.getName().equalsIgnoreCase("picture")) {
File imgFile = new File(nameValuePair.getValue());
FileBody fileBody = new FileBody(imgFile, "image/jpeg");
multipartEntity.addPart("post[picture]", fileBody);
} else {
multipartEntity.addPart("post[" + nameValuePair.getName() + "]", new StringBody(nameValuePair.getValue()));
}
}
httpPost.setEntity(multipartEntity);
HttpResponse response = httpClient.execute(httpPost, httpContext);
This will produce a POST like this:
{"post"=>{"description"=>"fhgg", "picture"=>#<ActionDispatch::Http::UploadedFile:0x00000004a6de08 #original_filename="IMG_20121211_174721.jpg", #content_type="image/jpeg", #headers="Content-Disposition: form-data; name=\"post[picture]\"; filename=\"IMG_20121211_174721.jpg\"\r\nContent-Type: image/jpeg\r\nContent-Transfer-Encoding: binary\r\n", #tempfile=#<File:/tmp/RackMultipart20121211-7101-3vq9wh>>}}
In the rails application your model attributes must have the same name you use in your request
, so in my case
class Post < ActiveRecord::Base
attr_accessible :description, :user_id, :picture
has_attached_file :picture # Paperclip stuff
...
end
I have also disabled the CSRF token from the rails application.
What I want I want to send a video from my SDcard to a server. I also want to send some parameters/value with it.
I have tried I have tried the following code:
public String SendToServer(String aUrl,File aFile)
{
HttpClient httpClient = new DefaultHttpClient();
HttpPost httpPost = new HttpPost(aUrl);
try
{
MultipartEntity entity = new MultipartEntity(HttpMultipartMode.BROWSER_COMPATIBLE);
entity.addPart("file", new FileBody(aFile));
entity.addPart("video[title]", new StringBody("testVideo"));
entity.addPart("video[type]", new StringBody("1"));
httpPost.setEntity(entity);
HttpContext localContext = new BasicHttpContext();
// Bind custom cookie store to the local context
localContext.setAttribute(ClientContext.COOKIE_STORE, Globals.sessionCookie);
HttpResponse response = httpClient.execute(httpPost, localContext);
HttpEntity resEntity = response.getEntity();
String Response = "";
if (response != null)
{
Response = EntityUtils.toString(resEntity);
}
return Response;
}
catch (IOException e)
{
e.printStackTrace();
}
return "Exception";
}
What is the problem When I run this code, I get stuck at this line
HttpResponse response = httpClient.execute(httpPost, localContext);
I get no exception, no response nothing at all. Can anyone please guide me, what is the problem in here?
The above code in my question was perfect, but I had the network problem. My device was connected to a hotspot(Connectify Software). When I connected to the original network, this code worked perfect.
I recommend you people to never trust a hotspot for this kind of functionality.
try using this way if want to send as content or esle I will upload the project by tonight
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost(url);
InputStreamEntity reqEntity = new InputStreamEntity(new FileInputStream(filePath), -1);
reqEntity.setContentType("binary/octet-stream");
reqEntity.setChunked(true); // Send in multiple parts if needed
httppost.setEntity(reqEntity);
HttpResponse response = httpclient.execute(httppost);
I am trying to send data to my server using HttpPost via the following code.
private boolean FacebookLogin(String url) {
boolean isDataSend = false;
try {
HttpClient client = new DefaultHttpClient();
HttpPost request = new HttpPost(url);
List<NameValuePair> value = new ArrayList<NameValuePair>();
value.add(new BasicNameValuePair("data", FacebookData()));
UrlEncodedFormEntity entity = new UrlEncodedFormEntity(value);
request.setEntity(entity);
HttpResponse res = client.execute(request);
if (res.getStatusLine().getStatusCode() == HttpStatus.SC_OK) {
String bufstring = EntityUtils.toString(res.getEntity(),
"UTF-8");
isDataSend = true;
}
} catch (Exception e) {
}
return isDataSend;
}
Is there any way i can have a look at how the $_POST looks on the server end. so that it will be easier for me to code the server part.
You can write the received $_POST on a file. Sometimes I do that. It's not the most elegant solution, but it works fine.
Try using a http proxy (e.g. Fiddler) for debugging, it helps a lot in these cases. You can set up an emulator to use this proxy for network communications, so you can inspect the messages sent and received. Check out the emulator docs on how to configure it to use a proxy.
I've been looking into this for the last day or two and can not seem to find a solution to my issue. I am trying to post an image to a server using httppost.
I have tried two ways of doing this and both complete the post but with no content i.e. the content length is 0.
The first is as follows:
String url = "MYURL";
HttpClient httpClient = new DefaultHttpClient();
try {
httpClient.getParams().setParameter("http.socket.timeout", new Integer(90000)); // 90 second
HttpPost post = new HttpPost(url);
File SDCardRoot = Environment.getExternalStorageDirectory();
File file = new File(SDCardRoot,"/DCIM/100MSDCF/DSC00004.jpg");
FileEntity entity;
entity = new FileEntity(file,"binary/octet-stream");
entity.setChunked(true);
post.setEntity(entity);
post.addHeader("Header", "UniqueName");
HttpResponse response = httpClient.execute(post);
if (response.getStatusLine().getStatusCode() != HttpStatus.SC_OK) {
Log.e("Here","--------Error--------Response Status line code:"+response.getStatusLine());
}else {
// Here every thing is fine.
}
HttpEntity resEntity = response.getEntity();
if (resEntity == null) {
Log.e("Here","---------Error No Response!!-----");
}
} catch (Exception ex) {
Log.e("Here","---------Error-----"+ex.getMessage());
ex.printStackTrace();
} finally {
httpClient.getConnectionManager().shutdown();
}
and the second is:
String url = "MYURL";
//File SDCardRoot = Environment.getExternalStorageDirectory();
File file = new File(Environment.getExternalStorageDirectory(),"/DCIM/100MSDCF/DSC00004.jpg");
try {
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost(url);
InputStreamEntity reqEntity = new InputStreamEntity(new FileInputStream(file), -1);
reqEntity.setContentType("binary/octet-stream");
reqEntity.setChunked(true);
// Send in multiple parts if needed
httppost.setEntity(reqEntity);
HttpResponse response = httpclient.execute(httppost);
Log.d("finishing", "The try catch function");
} catch (Exception e) {
// show error
}*/
As you can see I have hardcoded a path to a specific image, this is to be dynamic when I get it up and running.
Can anyone see what i'm doing wrong? Am I leaving out something? I know I use setChunked and setContenttype - is there a setContent option?
Any help would be grately appreciated.
Thanks,

You can use upload your image by sending multipart messages; you might find this discussion useful.
As part of my Android app, I'd like to upload bitmaps to be remotely stored. I have simple HTTP GET and POST communication working perfectly, but documentation on how to do a multipart POST seems to be as rare as unicorns.
Furthermore, I'd like to transmit the image directly from memory, instead of working with a file. In the example code below, I'm getting a byte array from a file to be used later on with HttpClient and MultipartEntity.
File input = new File("climb.jpg");
byte[] data = new byte[(int)input.length()];
FileInputStream fis = new FileInputStream(input);
fis.read(data);
ByteArrayPartSource baps = new ByteArrayPartSource(input.getName(), data);
This all seems fairly clear to me, except that I can't for the life of me find out where to get this ByteArrayPartSource. I have linked to the httpclient and httpmime JAR files, but no dice. I hear that the package structure changed drastically between HttpClient 3.x and 4.x.
Is anyone using this ByteArrayPartSource in Android, and how did they import it?
After digging around in the documentation and scouring the Internet, I came up with something that fit my needs. To make a multipart request such as a form POST, the following code did the trick for me:
File input = new File("climb.jpg");
DefaultHttpClient client = new DefaultHttpClient();
HttpPost post = new HttpPost("http://localhost:3000/routes");
MultipartEntity multi = new MultipartEntity(HttpMultipartMode.BROWSER_COMPATIBLE);
String line;
multi.addPart("name", new StringBody("test"));
multi.addPart("grade", new StringBody("test"));
multi.addPart("quality", new StringBody("test"));
multi.addPart("latitude", new StringBody("40.74"));
multi.addPart("longitude", new StringBody("40.74"));
multi.addPart("photo", new FileBody(input));
post.setEntity(multi);
HttpResponse resp = client.execute(post);
The HTTPMultipartMode.BROWSER_COMPATIBLE bit is very important. Thanks to Radomir's blog on this one.
try this:
HttpClient httpClient = new DefaultHttpClient() ;
HttpPost httpPost = new HttpPost("http://example.com");
MultipartEntity entity = new MultipartEntity();
entity.addPart("file", new FileBody(file));
httpPost.setEntity(entity );
HttpResponse response = null;
try {
response = httpClient.execute(httpPost);
} catch (ClientProtocolException e) {
Log.e("ClientProtocolException : "+e, e.getMessage());
} catch (IOException e) {
Log.e("IOException : "+e, e.getMessage());
}
Perhaps you can do following step to import library into your Android.
requirement library
- apache-mime4j-0.6.jar
- httpmime-4.0.1.jar
Right click your project and click properties
select java build path
select tab called "Order and Export"
Apply it
Fully uninstall you apk file with the adb uninstall due to existing apk not cater for new library
install again your apk
run it
Thanks,

I'm having the same problem. I'm trying to upload an image through MultiPart Entity and it seens that the several updates on HttpClient/MIME are cracking everything. I'm trying the following code, falling with an Error "NoClassDefFoundError":
public static void executeMultipartPost(File image, ArrayList<Cookie> cookies, String myUrlToPost) {
try {
// my post instance
HttpPost httppost = new HttpPost(myUrlToPost);
// setting cookies for the connection session
if (cookies != null && cookies.size() > 0) {
String cookieString = "";
for (int i=0; i<cookies.size(); ++i) {
cookieString += cookies.get(i).getName()+"="+cookies.get(i).getValue()+";";
}
cookieString += "domain=" + BaseUrl + "; " + "path=/";
httppost.addHeader("Cookie", cookieString);
}
// creating the http client
HttpClient httpclient = new DefaultHttpClient();
// creating the multientity part [ERROR OCCURS IN THIS BELLOW LINE]
MultipartEntity multipartEntity = new MultipartEntity();
multipartEntity.addPart("photoupload", new FileBody(image));
httppost.setEntity(multipartEntity);
HttpResponse response = httpclient.execute(httppost);
HttpEntity resEntity = response.getEntity();
} catch (Exception e) {}
}
This method is fully compilable and uses the httpclient-4.0.1.jar and httpmime-4.2.jar libs, but again, I remember that it crashs in the commented line for me.
