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,

In would like to write a simple Android application that takes a picture from the camera and uploads it to a webserver. Additionaly, I would like it to print in the screen the response from the server which is a simple text string.Do you know if there is any sample code that does something like that?

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.

I'm breaking into GUI programming with android, trying to compile and analyze Lunar Lander sample program. The instructions for using Eclipse say to select "Create project from existing source" but that option doesn't exist. If I select File->New->Project I can select "Java project from Existing Ant Buildfile". Using that I've tried selecting various xml files as "Ant Buildfile" but all give me the "The file selected is not a valid Ant buildfile" error.I just want to run GUI sample projects, preferably with Eclipse. Any useful tips will be appreciated.

I used some of the code from the Android sdk examples.Legally I know apache is compatible with GPL3 (license for my code), but what do I do about the copyright notice in the code?Do I keep the "Copyright (C) 2009 The Android Open Source Project" and apache license and just indicate the content was changed.Has anyone dealt with this? The Legal dept has no clue.

I have an application that requires that some images are uploaded to the device and replaced when the image changes.
For example, the first time the application is opened it goes ot the server and downloads some images, then the second time it verifies if there are new images to be downloaded, if there are it downloads them.
What could be the best approach to store the images on the device? creating a file folder for the application and a content provider?

The code seems no problem when I run it, but it stop unexpectedly in the emulator. I read some answer in the forum, It has to look at the logcat to see about the exception handler. But I do not really understand the logcat output. Please, developers, help me!. Below are the coding and my logcat output.

I have a listview in the first page of the application which takes almost a minute to populate. It would be nice if after each entry were generated (in a non-ui thread) the list added that entry - Simply calling refresh in the UI thread with a handler post does not do the trick. I use an ArrayAdapter constructed with a list.

My question concerns using aidl.exe (on a Windows system) from the command line. This question has nothing to do with Eclipse, Netbeans, etc. Included with the Android SDK are the following three AIDL definition files: IRemoteService.aidl IRemoteServiceCallback.aidl ISecondary.aidl. Located in the following directory: C:android-sdk-windowsplatformsandroid 2.1samplesApiDemossrccomexampleandroidapisapp. For the sake of simplicity, I copied aidl.exe into the above directory. Then, from a console Window, I successfully used the following two commands to generate .java files: C:Android-projectApiDemossrccomexampleandroidapisapp>aidl IRemoteServiceCallback.aidl C:Android-projectApiDemossrccomexampleandroidapisapp>aidl ISecondary.aidl. Invoking these commands produced the files: IRemoteServiceCallback.java and ISecondary.java, respectively. So far so good. I note that both .aidl files are simple; they include no 'import' statements..............................

I would like to tell the app to refresh the add occasionally, such as after two button clicks or something like that. Does anyone know how to do this and potentially have some sample code for it?
