Dear Developers.
I have a little experience with Android Application development. Now, I start with new R&D project. I do the research and do Google for few week but found nothing.
With the new USBManager interface of android, I can see some attached usb device, but that is not enough.
I see some information about the Picture Transfer protocol, but do not know how to use.
Let me summary, I have a android device with OTG connector and a USB webcam. Please give me some help to take a picture from that webcam in my Android application.
Any help will be appreciated.
Happy coding.

I know this is for programmers only but since I am looking for a programmer I figured it would be okay for me to post this here.

I own a HTC Universal (Cingular 8125) and I am also a diver. For a few years I looked at various Palm based dive logging software (when I had a Palm) but never bought one because I like to write longish descriptions of the dive and didn't want to do that in Graffiti or bring both a Palm and a portable keyboard on a dive trip. The desire to minimize electronic gadgets (and weight) is also why I never bring a laptop along with me. However, with the 8125 I have one device that I can bring with that lets me watch movies on the plane, listen to music on the beach, check my e-mail if I find find a wifi hotspot, and has the full keyboard and can use as a phone since it is GSM!
That being said, most dive comptures have the capacity to download information about the dive (depth, temperature, etc) to a computer. This information is very useful when you combine it with a log since it allows you to see what is called your dive profile and if you have the right logging software you can then combie this profile with your comments and create a really neat electronic log book.
However, the logging software for my computer, and I believe most computers, will not download to my device to any device running WM5. I had pretty much given up and figured I would have to wait awhile until these silly companies ralized there was a demand for WM5 and hopfully created software so you could download your computer information directly into your phone. However I recently found this device http://reefnet.ca/products/sensus/ which is very different. It is more of a logger than a dive comuter in that you do not interact with it during the dive and it does not give you any guidance about dive limits. One of the biggest things that makes it different is that they, "realizes the benefits of publishing the technical details of its data recording devices. If you're a software developer, dive organization, or just curious, you may download our free Developer's Guides. In them we carefully detail everything you need to know to be able to download data from Sensus recorders. The Sensus Ultra Developer's Guide is AVAILABLE NOW!"
So what I was thinking is that someone might be able to create software for WM5 so that we could download the information directly into a Pocket PC. This could then perhaps be combined with a program like this
http://blackwave.com/products/DiveAssistantPocketPC/index.aspx or this http://www.dreamdives.org/en/products/products1.htm to create the full package.
I think this would be a killer app that could make someone a few bucks. All I would ask for would be a free copy. I will even do the testing for free. the only big hurdle that I know of, and why they currently do not support download to WM5 is that the downloader uses serial ports.
Here is the link to their developers guide

dcdivenut: why do they sell Palm software? What does the Palm software do? Presumably it doesn't link directly to the logger? Although, IIRC, the Palm does have a kind of serial port built in.
Your biggest hurdle here clearly is the physical lack of a serial port.
Basically you've got a logger, and want to connect it to the phone? Converting the data into a universal format should be straight forward, most logging is done in clear and easy to manipulate text.
So, how do you get around the hardware limitation? You could wire together a serial to IRDA converter and blast the logs directly into the infra red port. But is that the kind of thing you want or need?

Or you could use a bluetooth to serial converter. It may actually be more stable and easier to use than IrDA.

I !think! the palm software allows you to download directly to the Palm via the serial port.
As far as an infrared port to get the data into the PC that is more or less exactly what I am looking for. Here is a long discussion on a scuba forum that involves a programmer from the company that might gove some additional information.
http://scubaboard.com/showthread.php?t=140213&highlight=sensus+ultra
I guess there are two challenges
1. Getting the data from the logger to the device either via some sort of serial/USB converter or serial/IRDA converter. I found this out there which would "seem" to work http://www.usbgear.com/IR-210S.html
2. Then having a program to take that data and with a decent GUI turn it into something displayable a la the palm and windows software on their website. Then possibly taking it a step further and integrating that into "dive log" software so that in addition to the profile information gathered from the logger you can record where you were, who you were with, what you saw, what equipment you had, etc. a la the blackwave or sharkpoint software.
Why not try styletap to run the palm software on the pocketpc windows mobile?

Hey there!
Okay, long story short:
I've got a Toshiba Intermec CN3 device (has USB Host controller) I would like to develop a driver for a USB scanner. Can anybody give me some tips on what needs to be done in order to achieve this?
The problem is that i can't get the Windows Mobile Platform Builder/Developer... because it's way to expensive.
I was thinking of trying to port the USB Scanner Support for Linux...
I know it might sound silly but i looked everywhere and i couldn't find something like this already done. Do you know of any similar drivers?
Thanks guys!
one dont require the platform builder to make or install a driver
for wm
a search for something like this could get you in the general direction of developing
devices drivers for windows mobile
http://www.google.dk/search?source=...+mobile&btnG=Google-søgning&meta=lr=&aq=f&oq=
The guy who started this thread - http://forum.xda-developers.com/showthread.php?t=480899&highlight=zeno+usb - will probably have some answers or tips.
Thank you both for replying.
@Rudegar i don't think you've understood my question ... i don't want to develop a driver for windows XP/Vista that will support a WM device.... what I need is to write a driver to be installed ON a specific windows mobile device that is capable of USB Hosting.
So the way i see it, when you connect a scanner (for example) to the device, the device should then recognize the scanner make it possible for the user to scan documents (for example) directly from the device...
@aiiro i've already pm'ed the guy, hopefully he'll notice my message
Hello everyone,
i was wondering if anyone could give me any tips about how to communicate with android device through usb from c++ or java(i guess that won't work without JNI though). I was trying to google up some documentation on this matter but found nothing. I wanted to program something like 'nokia ovi' suit as my b.c. 'thesis'.
Thanks for reading this, Tomas Herman
Hi,
Did you found any info on this ?
Certainly should be possible since Sync applications are working ...
Daniel
Yes, this is possible but AFAIK only as a hack. You can install the USB driver for the SDK and use adb's port forwarding. See /code.google.com/p/android-notifier/ as an example. Obviously, not an elegant solution and definitely not for the general Android user.
Gentlemen Good Day,
I am looking for 3 or 4 Developers for Android Platform.
The idea: When connecting an Android Phone via USB to a Personal Computer, the computer shall recognize the Phone as a regular USB Keyboard. But the
Phone won`t be used as a regular Keyboard,
it`s about something let`s say different and for more spectacular things.
So if you are interested and think you are able to do this, please write a mail to: "sonic.ops AT sonicsn4ke.net"
I will send you an e-mail containing the detailed description.
Regards, sonicsn4ke

You mean that you want the devs to create a windows driver, messing with android core to such levels may create problems.
XDA App
I managed to snag an Android Accessory Development Kit from Google IO.
After wrangling all the necessary code bits together I got the demo code running on the Arduino board and my Nexus One.
The first picture you can see the phone reading the sensors of the demo shield, button states, the temperature, a light sensor and the joystick position.
In the second picture the phone is controlling the led colors and has one relay turned on.
In the last picture you can see that the phone detects the board being plugged in, Android knows there is no app installed for the board and it cannot be found in market.
The Nexus One is running a rooted 2.3.4 ROM from this thread
P.S. Mod's can we get a forum section for Android Accessory Development?
Now for Pics.
Now that is bad a**!!! I was waiting for something like this!!
Hey, I've been attempting to hack in the support into CM7 (nightly, 2.3.4) on my EVO without much success. I've rebuilt the kernel with the necessary flag enabled and ripped the JAR/XML files from the Nexus S update.
I've monitored logcat and seen that it does find the framework JAR (the application wouldn't install otherwise since it's a needed feature) and a dmesg scan shows that the kernel driver is being initialized.
What's happening now is I plug in the ADK and the output from the Arduino board spams that it couldn't get a protocol version from the phone. The phone slows down to a crawl as its probably being spammed with requests from the ADK for a protocol version and doesn't know what to do.
I'm at a loss here as to what I could possibly be missing. If you have any insight through your own endeavors it would be much appreciated.
Great stuff! I was also at Google I/O and picked up an ADK. Can you post the apk file of your app? I'd love to try it out.
And if you're feeling generous...the code?
badass. good ****
Well done mate...
Have tried it out with arduino UNO?...
uh uh, why i wasn't at the Google I/O
Google is doing really good s**t nowadays. I suppose that Arduino will guest in my house in some time as I am fascinated
I am Actually using the ADK with my Nexus One on an Arduino UNO and an USB-Host Shield from Sparkfun, it works equal but only take a fraction to buy it
My first project is an interface for my Audi, at the moment i only use it to start the Motor, but in future i want to try to build a CAN-BUS interface...
Sure here is the compiled ADK.

The Arduino UNO doesn't have native USB Host support onboard like the megas.
You will need a USB Host shield and will have to modify the Arduino code.

You can find all the ADK instructions and code here.
Note: When you select your build target you must choose
Target Name - Vendor - Platform - API Level
"Google APIs" - "Google Inc." - "2.3.3" - "10"
Otherwise you will get errors trying to build on the new libs. The instructions on the ADK page wern't very clear about this. Took me awhile to figure that one out.
You will need to update your Android SDK if you don't see those options.
-Nik
As for the point of using an arduino uno, Oleg is providing an newer version of his USB lib, it now works with his shield and the ADK.
My car is almost starting with the ADK, i am only missing a few relays and stuff to get it completed but i posted a proof of concept on youtube. Text an explanation is all german, sorry for that
http://www.youtube.com/watch?v=FlvpMwSxgMg
if there are any questions Ill be here for you
Great stuff. I am really looking forward to this.
But what I don't get is which hard- and software is required:
- is 2.3.4 sufficient?
Answer: YES
- do other devices (running 2.3.4) than the Nexus 1/S work?
Answer: Pending
- will an Arduino Duemilanove board work?
Answer: NO
Thanks for your help, guys
Besides those questions I have one more:
- assuming I have a board that is connected to a power supply. will i be able to charge an Android device when connecting the board to the handset via USB?
Answer: depends on the boards and its power consumption/outlet. Basically, it should

+1 for a dedicated section.
I reckon it's gonna take off as soon as more USB host boards become available
My Arduino Duemilanove works perfectly
