Android :: Httpclient Multipart Form Upload
Jun 2, 2009I'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?
View 2 Replies View RelatedAndroid :: Alternative Way To Grab Progress On Multipart/form Upload
Jul 14, 2010As 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?
Android :: Multipart Upload - Transmit The Image Directly From Memory
Oct 12, 2010As 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.
Android :: Uploading An Image In A Multipart Message - Sample Code
May 10, 2009In 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,

View 1 Replies View RelatedAndroid :: How To Access HTML Form Data POSTed Through A WebView?
Aug 31, 2010I've started to write an app which provides the user with an HTML form via a WebView. As the form is not under my control, the data filled in may be sent as either GET or POST request. My app is required to capture the transported form data, that is, get a hold on what was entered into the form fields. Using an adequate callback from WebViewClient such as onPageLoaded(), it is easy to capture form data from a GET request. However, I cannot find any appropriate method to allow the same for POSTed data, i.e., be able to access the HTTP POST message body containing the form data. Am I missing a relevant callback here or is there simply no way to accomplish the specified goal with the given API (even the latest level 8)?

Jan 13, 2010I'm building an android app which should perform a GET on my site to get two cookies and then perform a post to the same site with these cookies.
As mentioned I start of with the GET and I'm using org.apache.http.client.HttpClient to perform this operation.
CODE:..............
So far so good. Don't mind the requiredCookies line yet, it will be used in the Java.net impl since I can't get the HttpClient one to work =(.
Let's take a look at the non working HttpClient Post part.
CODE:............
What happens now is that I perform a POST with the localContext where the cookies are stored. This doesn't work. I get a HTTP/1.1 401 No session. Since I had no luck with this I tried another approach(java.net.HttpURLConnection). Remember I still use the same GET part
CODE:.............
And VIOLA a 200 is displayed and everything works like a charm.
