Sending Images Using Http Post

I want to send an image from the android client to the django server using http post. The image is chosen from the gallery. At present, i am using list value name pairs to send the necessary data to the server and receiving responses from django in json. Can the same approach be used for images (with urls for images embedded in json responses)?

Also which of, accesssing images remotely without downloading them from the server or downloading and storing them in a bitmap array and using them locally is a better method? The images are few in number (<10) and small in size (50*50 dip).

The images chosen from the gallery are sent to the server after scaling it to required size.

Http Post And Get Request For Updating Map

I want to post data onto google map. Since there's no gdata for android, i reckon that i have to do it through http post and get which i am not good at. Is there some reference code for doing http post and get request? I guess it should be regarding the content type. Should i be calling get http on this url to retrieve the xml? And then modify the xml file and do a post http request to this same url again?

Uploading Image / Optional Tags Via Http Post

I am a newbie to android development; and i want to upload an image (not an image file on the device, but a frame from a camera preview) to a web-server. I searched around and got a snippet of code that can be used to upload a byte array. First, is this code right, or am i missing something here? Next, i want to know how can i simultaneously upload image and optional image tags to the server? I got to the level that i need to send a multi-part request, but can't seem to figure out the specifics. Can someone help me?

Also are there some 'best practices' to follow while doing this (like for responsiveness, etc)? Although this may be a little out-of-bounds for this forum, but i'm also writing the server any help/ pointers on how to write it to handle this post request that the client sends? Got to write the server in

I'm trying to integrate google app engine with an android app i've built but am having trouble with image processing. In the android app, i convert the image into a byte array and send it to app engine via http post to be put in a blob.

Access A Webpage (php) Sending Data With Post Method

I'm posting here because i searched the web and found nothing about how to http post. What i want to do is to access a webpage (php) sending data with the post method.

Actually, it's for a game i developed, and users are asking for online scores, so i wrote a php script that takes post data and writes the score in an sql database.

Http Get And Progressdialog

I have a small test application that simply grabs a url from an edittext box, before downloading the page source for the url, prompting the user to ask if it should display the contents, then doing so, or returning state. I would like to incorporate a progressdialog to appear whilst the get request is in action. I understand this would require threads, and i have attempted to implement this, but to no avail.could anyone assist in this matter?

Google App Engine Java And Http Performance

A friend and i are currently working on a turn-based game with chat with both desktop browser and android clients, with google app engine as the server.

We're using the java api for gae and using http for communication with the server. We've implemented simple chat functionality, and we're getting undesirable latencies 1-3 seconds from both the browser and android clients while just posting simple one-word chat messages.

My friend thought it would be best to use xmpp instead of http, but we want to use a google accounts cookie for authentication from the android client, and according to the gae documentation, xmpp clients cannot use a google accounts cookie and must use the user's password.

Does anyone have any suggestions as to where the latency might be coming from, how to troubleshoot it, and/or what to do about it?

Also, is anyone aware of any opensource implementations of chat (or something similar) on gae done in java? Can't seem to find any.

Force A Http Head Command To Terminate (for Httpclient And Curl)

If you run this command code.

You will notice immediately that the curl command hangs. (I am running this in cygwin/vista)

If you run it against twitter or facebook, curl terminates immediately.
I suspect it's because twitter & facebook returns connection: close.

In my android 1. 5 cupcake app, i am running the same command using the httpclient framework. And i notice that the connection hangs but terminates after the timeout (thank god for http 4. 0 ! ).

Is there an option to set in httpclient to terminate once i've received the relevant head
http headers ?

But i regularly need to send more then 1 piece of information in one go and using the single message.obj field won't work unless i use an object array or something.

What Information Is Mixzing Sending To Their Server

So i'm looking at media players and i found mixzing and am moderately impressed with the features in the program. I'm almost willing to fork over the $7, but the more i research it the more i find references to the app talking to a "server" for some reason. I have no idea why and there doesn't seem to be any information out there on why mixzing is talking to a 3rd party server. I know it generates recommendations and downloads album art, but the developer seems to imply that even if you turn off those two features in the app that it will still talk to the server.

Can someone tell me why that would be? Why does mixzing's server need information about my media library if it's not going to be generating recommendations? What other information is it passing to them about my device and my library?

Htc Evo 4g - Post A Video With Fps Fix Scrolling

Love the evo, and want to buy one but the sluggish and choppy web browser scrolling on full features pages (even w/o flash) compared to epic/droid x is killing my ability to do so.

Can anyone with a fps fixed kernel post a quick youtube ~30s or less of how the browser scrolling looks on say, engadget's full page? Or any other content heavy page. I've seen the home screen swiping fix videos, but nothing with this particular issue that's holding me back.
