Android :: Post Multipart Request With SDK
Jan 7, 2010
I'm trying to do something I thought would be relatively simple: Upload an image to a server with the Android SDK. I'm found a lot of example code:
http://groups.google.com/group/android-developers/browse_thread/thread/f9e17bbaf50c5fc/46145fcacd450e48
[url]
But neither work for me. The confusion I keep running into is what is really needed to make a multipart request. What is the simplest way to have a multipart upload (with an image) for Android?

I have a class that implements a multipart file upload. The code works on every java client I've tried it on but does not work on Android, *and* it's the only HTTP request code in my Android app that doesn't play nice with my back end service. I've looked through the posts to see if other are having similar issues but so far have only found posts like this http://groups.google.com/group/android-developers/msg/c4b0270153d194d9 , which are nearly the same as mine. T The symtoms I'm seeing are that the connection responseCode is "-1" & no entries show up in the Apache access or error logs. It seems as if the request is never making it off of the android platform. The code gets right through the connection writes in the debugger with no errors, but hangs on the connection read, times out and then returns with -1. Behavior is same for real phone and emulator. As I mentioned, this code is in use elsewhere and works fine.
Does anyone know of any gotchas one needs to look out for when posting a multipart file in Android? Anything about doing a POST or a POST w/ data on Android?
I'm including the code/class below so you can see what I'm up to.

I'm working on a sample application that does FileUpload using Multipart post, with Andorid 1.6 SDK the application works as expected but with 2.1 there is an issue basically the application does not execute and stays stale as soon as the upload process has started.
Basically, i use "java.net.URLConnection" for establishing connectivity with the server. Is there any changes made with the core Java API's in Android SDK 2.1 that causes this issue.

I would like to develop an application that uploads an image and some text data about that image.
To do that, I am trying to create a HTTP Multipart Post, as follows:
code:..........
My doubt is: how can I extract those values in the server? I would like to develop a Servlet to receive and process the post requests. In this Servlet I would need to extract these values in th request. Can you help me? Do you have any sample of server to answer the android multipart requests?

How do you print a POST request for debugging in Android?
I'm using either HttpPost or HttpURLConection.
The intent is to give the POST request to another member of the team so they can reproduce it in another platform.

I am working on my first Android Application. Now wat I want to do is to make a POST request to a restfull service running on server and I want the BODY of this request to be a JSon String. I am using GSon to generate the JSon to send to server. The code I am using to make the POST request follows:
HttpPost requisicao = new HttpPost();
requisicao.setURI(new URI(uri));
requisicao.setHeader("User-Agent", sUserAgent);
requisicao.setHeader("Content-type", "application/json");
HttpResponse resposta = null;.................

this Android code worked fine before, but i'm having problems for some reason. here is the request i'm trying to make: https://www.google.com/reader/api/0/token. i'm getting 400:Bad Request as a response, and i'm not sure why. isn't this the correct URL for requesting a token? the auth token is being passed as a header in all requests now, and i can request feed list, and it works just fine, so there's nothing wrong with the auth code. what gives? in addition, i can request a token in a normal browser, like Chrome, and get a token as a response body. so the request itself is not the problem. i just can't figure out what is wrong with my requests in code...

I am developing an Android app for a website. I'm trying to get some information from the website by sending a cookie using a HttpGet request. I don't know where I am going wrong with the request. I am using AsyncTask to send the request to the server. The request also uses a token which I receive when I login to the webpage. All this is clear in the code below. This is part of the process in the doInBackground() function of the Asynctask:
BufferedReader in = null;
JSONObject token = Login.getToken(); // Token received after login, used in the cookie
try {
r = token.get("session_token").toString();
} catch (JSONException e) {
// TODO Auto-generated catch block
e.printStackTrace();

I own a Xiaomi MI2S, running MIUI-3.8.16 @ Android version 4.1.1.JRO03L with Baseband version CEFWMAZM-2.0.128 017.
From my phone provider (Tele2) i have to dial a 1 (one) before my PIN-code when traveling abroad.
The code is accepted, I can be called and i can send and receive SMS messages.
However i cannot make phone-calls...
The error (?) is "DIAL request modified to SS request" and (very short) "not connected"

HttpClient 4 doesn't have that included anymore. The upstream project didn't integrate it from the 3.x client. I had to do exactly the same today. Basically I solved it by including some additional jars: mime4j httpmime This question was already on the list and there's some better explanation: http://groups.google.com/group/android-developers/msg/1ea124b384da9dc2 -- Urs My problem is that while i know what i have to include, i can't find a sensible download link for httpmime. the page points back to httpcore for downloads, but of course it's not in there any more (i checked). i was up for compiling it, but the source link takes me to the javadoc! something is definitely screwed up.

I'm trying to do multipart form upload using the 4.x httpclient on android. all the 4.x code samples I'm seeing use org.apache.http.entity.mime.MultipartEntity, but I'm running into a roadblock trying to find it. It's supposed to be in the httpmime project, but the download link for that project leads me back to httpcore, and the httpcore download doesn't contain that class. anyone else get multi part form upload to work?

As described in this answer you cannot grab a progress of a multipart/form POST upload in Android using only the Android SDK, because there is an issue with the stream buffering when using HttpURLConnection which will be fixed post Froyo (see http://code.google.com/p/android/issues/detail?id=3164#c6).
Since the Apache HttpClient 3.1 was removed from the SDK quite early and the new HttpClient, which is now part of the SDK, wasn't adopted completely (it misses multipart capabilities) you can add the missing parts (specifically apache-mime4j-0.6.jar and httpmime-4.0.1.jar) to perform a multipart/form-data upload AND grab the progress of the upload (also described in the answer mentioned above).
Now, the reason why I open a new question is, that doing as described leads to an enormous growth of the installed app size (in my case from 170kb to 732kb).
So, the question is: Is there any other way to perform a multipart/form-data upload and grab the upload progress without increasing the app size that much? Are there any other libraries one can use or is there any other alternative way, not mentioned here?

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.
CODE:..............
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:
CODE:.....
The HTTPMultipartMode.BROWSER_COMPATIBLE bit is very important.

In response to a request over here: http://bit.ly/E1Qqm
This is some sample code for uploading an image to the web, as part of a multipart message. It assumes that the photo is stored on the SD card as "photo.jpg". You'll need to download and add a couple of jar files to the project's built path - commons-httpclient.jar and httpcomponents-client-4.0-alpha4.
It is working on my device. However (big caveats here) - it's much slower than I would like, and much slower than other applications I've installed that upload photos. It also feels hacky - e.g. the way the background thread communicates problems with the upload to the main thread using variables. I'm sure there must be a neater way to do it.
If you figure out a way to improve the code,

I already use easytether for internet access on the go, what i need is an app that will allow me to tether my phone and dial a specific number of my choosing. I run a termninal program on my pc that connects to a remote terminal via land line that uses typical rs-232 communications, but easytether or pdanet do not allow dialing of specific numbers. I use a LG VX8360 with the drivers (LG CDMA USB mondem driver) and this gives me the option in my terminal program on my PC to select the LG phone and as modem and the terminal then dials which ever phone number i choose.
Picasa Web Albums - Tommy - dial up app#
Any one able to make and app like this? I believ essentially the phone needs to be displayed in the phone modem options under control panel to ensure that it will be available to the terminal application. The terminal app is Procomm Plus.

I'm looking for an app, but don't know if it exists. Basically what I want is an app that I can but a little disclaimer blurb, or something similar on and then have my customer sign it, all on the phone without the need for paper. If this could also be a part of a data base to keep track of customer info, that would be better.

Try a game I've released on an Evo? A user has reported that the controls are the wrong way round on the device. Like most arrogant developers :) I initially thought "dumb user error", but I suppose it *might* draw with the Y axis reversed.
The game is Pocket Racing Lite. Touching the left side of the screen should turn the car anti-clockwise, and the right side - clockwise.

The things that sometimes a brute force shake would be most helpful for and that I would pay money to have my phone do:
1. Shake to full brightness. When it's too bright to see the screen, it's a PITA to try to get the brightness turned up.
2. Shake to current phone call. Occasionally, I exit the phone app and it's frustrating not to be able to hop back over there quickly.
3. Shake to unlock. It's annoying to always be swiping when I just want to quickly check something on my phone. A quick shake would be much easier as an option.

Could someone provide the basic code to use if I want to perform a http request on android to the address "address" with the string "message" ? Also I'd like to check the server response and perform some actions if the right conditions meet , but I ' m unsure of how and when the server send back the response . My guess is that the response is gotten in a blocking function, or in an asynchronous function . Could you provide code or information on this as well ?

I have a HTTP GET request that I am attempting to send. I tried adding the parameters to this request by first creating a BasicHttpParams object and adding the parameters to that object, then calling setParams( basicHttpParms ) on my HttpGet object. This method fails. But if I manually add my parameters to my URL (i.e. append '?param1=value1śm2=value2') it succeeds.

I have a RingtonePreference in one of my classes and, upon return, the onActivityResult says that the requestCode being returned is 100.Unfortunately, I can't seem to find the *constant name* for this value.Is there a master list somewhere? It's just not jumping out at me in the documentation.
