Android :: Alternative Way To Grab Progress On Multipart/form Upload

Jul 14, 2010

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?

Android :: Httpclient Multipart Form Upload

Jun 2, 2009

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?

Android :: Can't Grab Progress On Http POST File Upload / Way To Fix?

Jul 9, 2010

I am developing an Android app which enables the user to upload a file to services like Twitpic and others.
The POST upload is done without any external libraries and works just fine. My only problem is, that I can't grab any progress because all the uploading is done when I receive the response, not while writing the bytes into the outputstream.

Android :: Multipart Upload - Transmit The Image Directly From Memory

Oct 12, 2010

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.

Jelly Bean :: Attachment Upload Progress Bar For Hotmail?

Feb 13, 2014

I often run over poor connections. Attachment upload takes time. (I use Hotmail) I am often not sure if the upload is continuing ok and if it is worth waiting for.

In Chrome Webmail (Hotmail) I can see attachment upload progress. But using the web demands more bandwidth.

Is there a mail app for Hotmail that monitors this progress. How is "sending in the outbox" coming along?

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?

Android :: Need Download Link For Httpclient Multipart

Jun 9, 2009

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.

Android :: Multipart File Post Fails

Jul 13, 2009

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.

Android :: MultiPart Post File Not Working On 2.1 SDK

Apr 27, 2010

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.

Android :: Uploading An Image In A Multipart Message - Sample Code

May 10, 2009

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,
