[Q] Has anyone tried using the NFC of 2.3? - Android Software Development

Has anyone here tried to build an app using the new NFC feature of Android 2.3? I was just thinking of a few ideas where it might be useful and I was wondering if anyone has started implementing this feature into any new or existing apps and what their thoughts were on it.
I think it a great idea and could have some pretty neat real-world applications.

I'd like to know if the nexus S can read normal RFID chips. I'd like an app to scan the chip in my cat!

Lol. You mean that ID chip that we put in cats and dogs via needle so that if they have a runaway pet, they can identify it? (I worked at a vet's office for 4 years).

Any Questions?

I've got an Epic 4G waiting for me when I get home today. If anyone has any questions or requests Ill be more than happy to answer them!

...is it epic?
What color is the notification light on the phone? is it one color or can is do pretty much any color under the rainbow, or just a few? BGR is the only source I saw officially state that the notification light is in fact a notification light and they only said that it is red.
If you wouldn't mind loading some apps on SD card testing their open/close response.
I'm also interested in the notification light.

Wouldn't he need Froyo for that?
It looks like there is a system app called GPSSetup. Can you run that? What does it do?
Please post some videos of it in action. Doing some benchmark test from popular apps would be nice too
Will do. Two and a half hours from home!

natually you need to do some real world testing of the GPS to see if it actually works and is accurate. Take a drive somewhere with google maps loaded up and see how well and accurate the GPS please

Just driving around is a pretty unrevealing test. If you are going to field-test the GPS, please use a little more rigor than that: Install and use My Tracks to capture several tracks on complex driving courses with stops, turns, and fast curves. Also some walking courses. You can upload the results to Google My Maps and post the links for others to peruse.
Then use GPS Test and report the results being shown when getting an outdoor fix (number of satellites seen, used; reported accuracy; SNR levels for satellites used, time to first fix.)
Alright gang.
First tests:
1.) Notification light - red.
Can't test any other colors. Don't know if it can change.
2.) Quadrant benchmark - 960. I/O score improves, 3D, etc. Most improved by a little. I/O a lot.
Here's my benchmarks: http://briefmobile.com/samsung-epic-4g-benchmarked
3.) GPS -- worked well with initial test. Found me in my court outside. Will do more testing later.
4.) Speed of the phone - unrivaled. Possibly the fastest, baddest Android-powered device yet. I own a Captivate, and this thing BLOWS the Captivate out of the water.
When I apply the EXT2 lag fix on Captivate, it brings Captivate up to par with the Epic 4G. But, Epic is fast right out of the box. Boot up times are nice and fast. No ten minutes of loading crap.
Sidenote: Wish I had the Epic drivers. I have no way of connecting this thing to my PC. Of course the driver site isn't up yet. The phone's not out for ten more days!
FM Radio useable?
What version of BT?
Anyway you can try out vid out?
Any way you could post a link to a kernel dump?
Just run
Cat /dev/bml7 > /sdcard/bml7.dump

Can't run this without any drivers to connect...
Bluetooth - 3.0 like all Galaxy S devices.
FM radio - no way to test... I'm assuming it's disabled like the Captivate. No radio application.
TV out - I'll see if I can test it later today... but I don't think I have the right cords.
You should be able to run this from connectbot and your pc should see the sd card without pc drivers.

Is it running TouchWiz 2.5? I've heard that it's running 2.5 but I don't believe it.

Yes, the version of TouchWiz is slightly different. Not any better or worse necessarily. Just a different version.
Samsung has told me previously that the TouchWiz would be updated with the Android 2.2 rollout. But, all of the Galaxy S line devices will be receiving updated skins with 2.2. A few changes coming to every one.
I have a few questions. First I'd like to know if the Epic 4G has video out like on the other Galaxy S variants through composite cables via the 3.5mm jack, and HDMI through the micro USB port? Thanks in advance

[Q] Barcode Scanner

Obviously, the Nexus 7 does not have a camera installed on its back side. Can anyone confirm if any barcode scanning apps would work? I know it would be awkward trying to scan a barcode with the front camera, but if anyone knows please reply!

How would you expect to line up the barcode without being able to look at the screen? I think scanning is out...
None of the scanning apps allow use of the front facing camera, so unless they decide to add support, they're not going to work.
and it's incredibly unlikely to be honest.
Unlikely I agree.
But think about the last time you bought groceries.
The scanner is like a big tablet, and you just pass the item in front of the camera.
I can see no technical reason why that model would not work.
oh i'm sure it would work with the front camera, but none of the apps support it as far as i know.
I'm sure you could request that the devs add support. up to them if they want to.
A high resolution, autofocus camera is needed to read most barcodes. The front camera might be able to handle QR codes.
Yeaa... I thought about this a few days after i posted this.... Isnt that what phones are for? because im not bringing my tablet around anyway.. just thought it would be a cool thing to have, stupid question by my

I don't think it is stupid. It may well be technologically unlikely. But no harm in asking the question. And if someone did this I'd be delighted. It would mean I could do my home shopping grocery order much quicker by just standing in my kitchen. I accept however that it is a long shot (very long).
Dunno knw why they gave a camera on first place..... To create a cheaper tablet.?

Video calls. That appears to be the only real reason, for Skype and other VOIP systems. The resolution and fixed focus would bear that out, too. It's clearly not ment to be used as a regular camera, scanner, etc (though I'm sure someone will figure out how to do it...)
And that's fine with me, because the competition (Kindle Fire, Nook) don't have even that camera.
Scanning apps
There are a couple of scanning apps now for the Nexus 7 such as LearnPad Scanner (I can't post links yet)
Learn pad does work with bar and qr codes. Just scanned my Pepsi bottle.

That is cool, sadly I can't get it to read any barcodes though. I don't know what I'm doing wrong.
Worked great for me for scanning in barcode for Google Authenticator.
Are you holding the tablet in the correct orientation (landscape with camera on left when looking at N7) ?

Yes I am. It must be me if it is working for everyone else. Or maybe UK barcodes don't work on it. It says it only does one type in its help pages.

Hi, I'm an author of Barcode Scanner. It doesn't use the front camera since only rear cameras are treated as 'real' cameras by Android, and the API for using second cameras appeared later than the API leve the app supports (2.3), which makes it tricker.
We made a 'premium' version that does, among other things, support front-camera-only devices like the Nexus 7.
Search for "barcode scanner plus" on Google Play -- sorry I can't posts links yet.

Sean,
Would it be possible to have the app scan a bar-code using a phone and send the information via Bluetooth to the tablet? That way we have the best of both worlds. I would certianly pay for "Plus" to get this option!
Just found this... was looking for a way to scan QR codes for shipping labels into the Nexus 7. Learnscan works good, just takes a bit getting used to lining it up as it is backwards and reversed from what you are used to.
Works good enough in a lit room. Scanning stuff off the screen is easier.
Can you just put the tablet down on the table, bring the product to the camera, and look at the screen to position the barcode?
It seems very doable.
you can... in fact that is what I end up doing, but it is much harder than you think it might be. the app changes the camera view by rotating it, so you are working against where you think you should be moving to have you end up seeing....
If you had anything to drink, forget about it...
You have to actually try it to see what I mean... its like driving backwards except the camera view you are looking at is rotated 90 degrees.
the app btw is free, or least the one I tried.

Ideas for DX after life as a phone?

I posted this question in another forum, and have some great responses so far, but I wanted to see what people's opinions were here as well:
This topic may sound a bit strange, but I'm wondering what people have done/plan to do once they have upgraded to a new phone after using the DX. Ideally, I'd like to use it for multimedia/music purposes but I'm wondering if there have ever been any ROMs or anything similar that could perhaps save some internal storage space or increase battery life by getting rid of the "data" and phone/radio aspects of the device. I do have the official Motorola car and home/multimedia docks so I can still find some realistic uses for my DX (especially if I'm trying to save battery on my new S3) but I wanted to see if anyone has ever done this and what ideas people may have. I realize that battery life could potentially be significantly better with no data usage (aside from occasional wi-fi) though, to be honest, I don't even know if what I'm asking about is even technically possible (i.e- creating a ROM for this purpose only) but I figured it couldn't hurt to ask. Thanks!
It makes a good streaming media player.
There aren't any ROMs that remove the phone functionality, but there's always airplane mode.

I've turned my DX into a VOIP home phone using sipdroid. I also use it for Torque and hooking up as a media streaming player to the speakers in my garage.
I'm running Gingerbread CM 7.1 kang and have used sqlite to disable the "disabling" of wifi in airplane mode. I get a solid two days of use before charging.

Does/Has anybody used App Game Kit?

I've been using AppGameKit for a while.
Has anybody else tried it?
What do you think of it?
In my experience, it's quite good for prototyping apps, and even releases, although it might have some performance issues on slower phones

Features

Confession time. I'm a poor excuse for a flag ship smart phone user. I got this cool s5 and among other things I've never used tool box, multi window, fingerprint reader, heartbeat sensor, etc. Aside from the speed and display I may as well be still using my Optimus V. Anyone else? Tips on how to get started using any of this cool stuff?
I don't use any of it either. They were the first things I dumped when I rooted.
OK so it looks like no one uses those geegaws?
