Kill App is possible

Use Tasker combined with NFC

When i put my phone in car cradle which has NFC sticker in it, first it turns off wifi turns on bluetooth, sets screen brightness on full turns off lockscreen,starts Car Home Ultra and Camera Alert and also if I recieve a text message whilst driving it tells me who its from and reads it to me.

When I get out of the car using tasker when Bluetooth loses its connection that triggers tasker to kill the car based apps I have running and turn bluetooth off and set screen lock back on.

This sounds interesting, could you give some basic instructions on how to get this set up? In psrticular the text reading thing and the tasker cut off?

Many thsnks as always.
[Samsung Galaxy Nexus] eddie_gordo:
Hi there,

I started using NFC Task Launcher a few days ago. I have noticed that anyone can read the tags that I write on... This is not a BIG problem as all my tags are in a controlled environment (home, work, car, etc) but it was somehow strange when one of my work colleagues scanned one of my tags with his HTC One X and his device opened the messaging app to send an SMS to my girlfriend's number. :P Is there a way to make the device readable by my device only?

And btw, when I try to write a tag, there is a checkbox that asks me if I want to make the tag read-only. What does this do exactly? I never checked because I'm afraid that this turns the tag read-only forever and may not be revertible, and I don't want that. :)

Thanks!
[Samsung Galaxy Nexus] krohnjw:
You can't make it readable by your device only right now. This is by design. We've kicked around allowing encryption (with a local key you set up) and doing some basic encryption. That may get implemented at some point in the future, but it's not an imminent feature we are looking at.

Read only makes it read only. Don't tick that unless you are done writing new content to a tag.
[Samsung Galaxy Nexus] eddie_gordo:
Thank you for the answer.. That would be a pretty neat feature to have, please take that in consideration when you can.. :) That would improve security in using tags!

Keep up the good work on the app, it's great!
[Samsung Galaxy Nexus] jlim0512:
I've already rooted my phone but I'm having trouble making NFC Task Launcher a system app to enable GPS. Could someone help me please? Thank you in advanced.
[Samsung Galaxy Nexus] krohnjw:
What happens when you hit the make system app button?
[Samsung Galaxy Nexus] jlim0512:
it says exacly that I must "make NFC Task Launcher a system app to enable GPS"
[Samsung Galaxy Nexus] krohnjw:
Yeah, new task tag, add action, wifi & BT, GPS

It will tell you it needs to be a system app and there is a button to make a system app there.
[Samsung Galaxy Nexus] animatechnica:
You need to use titanium backup to make it a system app
[Samsung Galaxy Nexus] krohnjw:
You can, however you don't need to. Add GPS to a tag. The button to do it is right there if write_secure_settings isn't granted.

Photo attached for reference.

o wow i am really blind. Thanks for you help!
[Samsung Galaxy Nexus] droid_does:
Quick question.

Is it possible to use this to set call forwarding and disabling call forwarding? We don't have good cell reception in my new house and my mum always sets call forwarding when she gets home but she's sick of manually enabling it and disabling it.

Which tags would you guys recommend for good ($/value ratio)?
[Samsung Galaxy Nexus] krohnjw:
How do you do it manually, dialer code?

NTAG203 - good size, cost and great rf performance.
[Samsung Galaxy Nexus] droid_does:
Thanks

I usually go to dialler, menu, call forwarding then set it from there.

Edit : maybe tasker? I don't know what's the most foolproof easiest way. Any suggestions?
[Samsung Galaxy Nexus] tgerbracht:
Feature request:

With aokp and soon cm10 allowing screen off nfc use and with many people using tags that alternate between two profiles, is it possible for the app to have a handful of sounds available so we can pick a tone to play for one profile and another for the alternate profile? Thanks for your consideration.
[Samsung Galaxy Nexus] krohnjw:
Playing sounds is something we are looking at adding in a future release. Whether it's a list of available sounds or *any* custom sounds is still something I'm kicking around.
[Samsung Galaxy Nexus] gkrawiec:
Hi krohnjw,

We have now added stickers to our bundles in order to differentiate tags according to profiles. I think

we got most of the common profiles :)

Do you happen to know what most people use task launcher for? We found home, car, sport, kitchen, nightstand, office, development modes were the most common.

[Samsung Galaxy Nexus] krohnjw:
That's pretty much what we see as well.
[Samsung Galaxy Nexus] gkrawiec:
Cool, thanks for the feedback!
[Samsung Galaxy Nexus] CtK4949:
Great app!!

I have been using it for a couple of weeks. But now it will only work after i restart my phone. Then it will only work a couple of times before i have to restart my phone to use it again.

I am using a Verizon Galaxy Nexus, with CM10 Kang ROM.

Any ideas why it is doing this??

thanks!!
[Samsung Galaxy Nexus] krohnjw:
No, can you grab the logcat output when this occurs and attach it here or send it to me? Sounds like an issue with the nfc service.
[Samsung Galaxy Nexus] Jamesch:
Hi

Good job with the app.

One thing I would like to do, but haven't managed yet:

I would like to check in to a specific location on Foursquare totally automatically. There is an app for that: NFC Checkin.

My problem is that I would also like to add more tasks to my tag, like turning on WiFi, and only Task Launcher allows that,

I was able to figure out that NFC Checkin only writes an URL to the tag (urn:nfc:wkt:U, Identifier: 0x03 and the the actual address, which contains a long HEX number, that is actually the data that is used, the URL is not activated by itself, e.g.: flavor.de/545abc156456def4546), and when that is opened with the app it checks in (if it was allowed access on foursquare). For some reason if I put an URL action on the tag with NFC Task Launcher and read it, my phone doesn't offer NFC Checkin as an option to open the address.

I realize that your app doesn't write a regular URL on the tag, but in the end it should function the same way. When I read a tag written with task launcher the phone offers Dolphin, Opera and built-in browser. When I read NFC Checkin tag it only offers Opera and NFC Checkin.

Is there a way to get this to work?

thanks
[Samsung Galaxy Nexus] dotamaple:
can it connect to a secure Wifi network automatically and not entering the password manually? :D

when guests come to my house i can use this to let them connect to my wifi without knowing my password :o
[Samsung Galaxy Nexus] krohnjw:
Yes.
[Samsung Galaxy Nexus] leranp:
in the past(before 3.8 ) it was possible to make a lite tag , and now not

the "smaller switch tags" not working at all

and the name of the task is not appare

can someone send me the older version (before 3.8) ?
[Samsung Galaxy Nexus] krohnjw:
Tag names are now written to tags themselves. Re-write any tags and you'll see the names again. This was to address some glaring issues with using a local lookup system.

You can still write small switch tags. In your screenshot you have the box ticked to write the names with the tag. Untick that box and re-write it. There's currently an issue with small switch tags where they don't do a local lookup on the name - they only display the actions. That will be fixed shortly.
[Samsung Galaxy Nexus] leranp:
o.k , thanks
[Samsung Galaxy Nexus] Royal2000H:
Sorry, I'm not understanding what the Tag Name does. In other words, what are the pros and cons to selecting "Include Tag Name"

Also, the more bites the tag is, do I need to leave the phone on the tag slightly longer? In other words, if I can make the same tag 70 bytes or 30 bytes, is there a benefit to compacting it to 30 even if my NFC Tag/sticker (NTAG203) supports both?
[Samsung Galaxy Nexus] meta96:
Wifi on/of and upnp

I want to use NFC launcher to start wifi and then UPNPlay. In my setup upnp starts to fast, so i would need some seconds before the system is settled. So I am missing a "wait 10 SECONDS" action. Is there one, i didn't find? I think tasker could do that, but i also think it should/could be part of NFC Launcher, or did `ve missed so mething?

thanx
[Samsung Galaxy Nexus] krohnjw:
If you include the Tag Name the name will be written to the tag (e.g. Home). When anyone scans this tag it will show them "Home". If you do not write the name it will not show home, rather it will show the list of included actions that are performed.

You won't see a difference in read time.
[Samsung Galaxy Nexus] krohnjw:
Adding an arbitrary pause isn't currently present. It will be in the next release though (3.9).
[Samsung Galaxy Nexus] meta96:
Thanx.:good:

2) I would like an action: "Back to homescreen"

3) and mediacontrols: "start/pause/stop/next"

Would these also be possible? Thanx, again

4) I can start UPNPlay* with NFC Launcer, but i can't stop/kill it ... why?

*) also other upnp apps (bubble, fritz)
[Samsung Galaxy Nexus] krohnjw:
2.)

I'll take a look. Emulating a home screen button press is on the list of potential enhancements. I assume this would suffice?

3.)

Start/Stop is already in (Android makes it one function, not two distinct).

Next / Previous will make it in soon

4.)

Are you rooted?
[Samsung Galaxy Nexus] meta96:
Yes

Great :good:, sorry, didn't expect it in this category/subdirectory > my fault.

Great.

What a question, tztztz, shure ;) > just for the records, using a xperia p. My main problem is, leaving the house with running upnp brings up an error message and i have to kill it myself, no real problem, but not nice.
[Samsung Galaxy Nexus] krohnjw:
If you're rooted it should kill the process. Unless it's spawning another process in the background somewhere. If you enable debugging you can send me the log from killing it (/sdcard/NFCTL/) and I'll take a look.
[Samsung Galaxy Nexus] meta96:
I ´ve sent you my log file per private message. At first, maybe i ve to wait for 3.9 because of the time delay setting. Next i recognized, i cant stop any app. It looks like the app stops, but then the notification shows app is running (again). I ve tested it with pulse, upnplay, bubbleupnp. But maybe it is a sony-ics-thing.

Play/Stop works fine for the local media player, but not with upnplay/bubbleupnp, maybe they did not use the play/stop routine ...

But still loving your app. To start wlan, home wlan login and start upnplay or bubbleupnp, it is great enough :o

best c.

[Samsung Galaxy Nexus] petrsiri:
Guys I have read most of the thread but I still haven't fully understood how it is supposed to work.

I have created a tag which turns bluetooth on for use in my car. Tag is at a spot where is always in contact with the back of the phone. I have noticed that phone reads the tag every time I unlock it for.Is that normal? Shouldn't the phone ignore the tag since it is already active?
[Samsung Galaxy Nexus] gkrawiec:
That is normal. NFC turns off everytime the phone is locked, so everytime you unlock it it turns on again and reads it.

For it not to re-read it you would have to leave your phone unlocked.
[Samsung Galaxy Nexus] Royal2000H:
I would suggest you put your tag in a different spot than where you keep the phone.

And simply put the phone up to it when you get in and out of the car
[Samsung Galaxy Nexus] krohnjw:
You can enable rate limiting in the app settings and it will ignore that tag for a period of time that you define. This may help if you want to leave the device on the tag.
[Samsung Galaxy Nexus] petrsiri:
Thanks a lot for your answers.

Is anyone aware of a mod enabling nfc reading in galaxy nexus for jelly bean stock based roms when screen is off?
[Samsung Galaxy Nexus] Crafty77:
Finding the app great and easy to use, I am looking for a music player that I can start (possibly as an activity?) that will start playing music in shuffle mode, does anyone know of one ?

I've tried using the media start/stop which works fine, apart from it starts the default music app (international S3) which happens to have a bug/feature whereby it falls out of shuffle mode if the app is closed.

Thanks!

Format blank tags using Windows App

While Google clearly needs to resolve this issue, for now our Windows App can be used to take an unformatted tag and format it as NDEF. Just write a random record (dont lock it) and it will be all set. All of the tags from buynfctags-com come unformatted. This is good since not everyone is using NDEF. We can also encode them for you if want to go that route.

Is there any way I can use my Galaxy Nexus as the NFC reader over USB?
[Samsung Galaxy Nexus] :
Loved the App and the devolper over in the Nexus S forums. Great to see this in here.
[Samsung Galaxy Nexus] keyboardr:
I noticed it includes a Tasker plugin; any chance on supporting a Locale plugin? I know a lot of profiles are cross-compatible which leads me to believe that the code isn't much different. The only issue I could see is that Tasker is more event based whereas Locale is more state based. You could probably use that READ_LOGS permission, but only read the logcat when Locale queries your state. You might release this part as a separate package because of the permissions changes needed. Anyway, it would be greatly appreciated.
[Samsung Galaxy Nexus] Northernmost:
I received my first lot of tags (these Mifare 1K S50 ones) and I'm thinking they must be unformatted but wanting to check with someone smarter than I to be sure. When I use NFC Task Launcher to try and format them and I tap the tag I get a toaster saying "tag not supported".

Does this mean my tags are unformatted and I have to wait for Google to fix or have I bought the wrong ones? sorry if this is answered elsewhere. I have read it all through and searched but to no avail.
[Samsung Galaxy Nexus] krohnjw:
It most likely means they are just not formatted.

Grab NFC Tag Info from the market and check the tag techs reported on them. List them here and I can tell you if it's supported and just affected by this bug or not supported.
[Samsung Galaxy Nexus] Northernmost:
Ta. I guess the ndef info "NFC data set storage not present" means it's just not formatted. Full report goes a little something like this...

Any NFC Forum type tags formatted to NDEF. Tagstand.com, Tagage.net and nfcdog.com are selling these pre-formatted. See here for some other vendors: http://www.jwksoftware.com/nfc-tags

If in doubt contact the vendor and ask/verify the tags ordered can/will be pre-formated with an NDEF message.

[Samsung Galaxy Nexus] KiNG OMaR:
These are the ones I got, they look pretty stylish to me ;) LOGO TYPE 2 NFC STICKER - ULTRALIGHT C - SQUARE (35MM X 35MM)

When you go to your cart to make the purchase be sure to add a note that says you want your tags preformatted.

Tagstand does not ship preformatted tags by default, I ran into this incident but they sent out my previous order preformatted for free and allowed me to keep the old tags :) The new ones should be coming in today!
[Samsung Galaxy Nexus] krohnjw:
Given their potential to be rather large the 1K tags may be your best bet (even though they aren't technically NFC Forum type tags). They don't work well with Blackberries as a result and aren't guaranteed for all devices.

However, they offer a large upgrade in storage. There are various apps to write vCard data on the Market - all should work. Some try to include contact images (which results in a vCard that is too large).

If you want to go with a tag that will be compliant with the most phones then check out teh Ultralight C (144 bytes). It's more limited on space, but will be the best size wise for your buck (unless you want to spend more on the Desfire tags).
[Samsung Galaxy Nexus] sblantipodi:
do you know some shops that sells preformatted key fobs in UK?

I need UK for shipment costs.
[Samsung Galaxy Nexus] Northernmost:
nfcdog.com (that's nfc-supplies shop), will do it. I placed an order and emailed by reply to the order confirmation asking for them to be formatted as ndef for a gnex. They did and dispatched on the same day :-)
[Samsung Galaxy Nexus] krohnjw:
Looks like 4.0.3 fixes the NFC formatting issue (It works again on my Nexus S).
[Samsung Galaxy Nexus] drahyrt:
Hi Krohnjw

Just as a feedback point, is it possible to have a task that would set off an alarm in say 5 minutes, rather than set alarm for 5 minutes from now?

As it is this just adds the 5 minutes plus a current time... the tag will only alarm for a set time, rather than the desired 5 minutes from now at any time I scan the tag (at least for me anyway), would you consider it? Maybe tasker can do this if not in combination.

Great app, glad to support you in my purchase, even though you have a free link, BTW, how often does it keep asking for licence permissions?

(Can't wait for google to release the 4.03 to gsm users already........)

FYI purchased tags from buynfctags.com vvv helpful, and some of their tags work without preformatting UPM brand

Nice app, just playing with it at the moment but seems useful.

One quick question, I've disabled Notification Sound and Vibrate within the app's Settings screen, but my Galaxy S3 still beeps every time I scan a tag. Most of the time that's OK, but the tag I want to set up for bedtime use is basically to make the phone quiet/dim (so I don't disturb my partner when I get home after a late shift at work) but the loud beep when the tag is scanned somewhat negates that aim... am I doing something wrong?

Andre
[Samsung Galaxy Nexus] krohnjw:
That sound is part of the NFC service. It can't be disabled unless you flash a modified NFC service to your device.
[Samsung Galaxy Nexus] andrewilley:
Thanks. I've already installed a patched version of nfc.apk (so the sensor runs in locked mode too) but I've not spotted anywhere talking about a modded version to disable the sound. Any pointers?

Andre
[Samsung Galaxy Nexus] krohnjw:
The sounds are in the resource folder in the APK. You'll need to replace them and repack.
[Samsung Galaxy Nexus] andrewilley:
Excellent, thank you for the quick response.

I know APKs are basically just ZIP archives, but I've never edited one - can I simply use WinRAR to replace the start.ogg and other sound files with silent versions, or do I need to do anything else with the archive file afterwards (not sure if APKs have any special checksums or other info added).

[Edit: Search is, of course, my friend... APK Manager at http://xdaforums.com/showthread.php?t=695701 covers it nicely in case anyone else wants to do the same thing. I think just tweaking an OGG file should be OK with a plain WinRAR re-save though - could someone confirm that please?]

So I'm not exactly following with this preformatted NFC Tag. Can the Galaxy Nexus (4.0.2) currently assign tasks to NFC chips if they are preformatted? What exactly would be the advantage of buying unformatted tags?
[Samsung Galaxy Nexus] okeefferd:
I ended up buying some tags from digikey.com. Unformatted for sure, but since they are in MN and these tags are so light, I'll see them tomorrow and they offer basic Priority Mail service. 5 fobs and 5 inlay tags, all 1k for about $15. Now, lets hope that 4.0.3 update rolls out soon so I can use them.

From what I understand, you can write tags if they are pre-formatted, so the aforementioned apps should work. If the tags are not formatted, you are SOL until the update rolls out.
[Samsung Galaxy Nexus] JimmyHACK:
The starter pack from tagstand preformatted? Don't see any format info on their site. Just want to get some to play around with and your app.

Task ideas thread?

Does anyone have a link to an ideas thread? I have a couple, but i'd really like to see how everyone else is or intends on using NFC.

I like the dock ideas, if the docks for the CDMA nexus ever come out, love the idea about having a work profile and home profile activated, tasker integration should bring some great ideas as well.

Other than those couple ideas, can't imagine what else I would use them for?
[Samsung Galaxy Nexus] igl007:
I agree, I got my tags yesterday and started playing around with them. I simply wrote the tag with a tasker task. Then i can play around with that to change it. I made one for home that turns wifi on, bt off, ringer to full, and some speech that says "welcome home chris". Ok, yeah that is tacky... but so is having a NFC sticker on my door :)

What I really would love to figure out is how to make it do things within an app. For example, I'd like it to launch the google tv app, and turn my tv on when i set the phone on the coffee table. I can get it to launch the app, thats easy... but how can i press a button in the app?
