[APP] LocationAware v0.3, PCBuddy {14th April 2010}

Location Aware is an automatic volume profile switcher.
This application works out of the data received from GSM signals.(NO CDMA)
so almost all windows mobile devices can use it.I developed it on my elf and it seems it is working
Requires GSM network, Windows Mobile , .Net CF 3.5
1. Battery Friendly, No active background process.
2. No GPS needed.
3. User configurable interval to check for location.
4. Can save settings automatically v0.3
Well it works like this: (May change per version)
1. Install it.
2. Open the Location Aware(from programs)
3. When ever you start the app it will vibrate the device 2 times and then asks "Add this Location".
4. Click OK and it prompts to save the volume level for this location and save.
5. Adjust the volume level as you desire from the Slider on right hand side of screen.
6. Then goto Menu and Save Location Mode, this should save the setting for this location(Prompt will be displayed).
7. Now you can let the application run itself every X mins to check for new location and prompt you whenever a new location is found.
8. To set the interval time goto Menu -> "Stopped" this should open up a panel to enter the interval time, fill it and click set. "Stopped" should be changed to "Running". Now you can Exit.
9. If prompt is not dismissed or OKayed within 1 min(Automode). It dismisses itself and will prompt again if new location is found after next X mins.
10. The limit for interval is 2-60 mins, that means the app will run itself after every X mins and check for location, if a new location is found it vibrates
and then asks you to save this location or not, in case you dont respond to it, it will close itself after 1 min.
and in case the location was already saved it will automatically apply the volume profile.
Basically as you keep on using it the database keeps on growing and in parallel profile settings gets more customized.
PS: You may notice that the taskbar volume indicator is not changed, but that is normal. The volume setting is still applied as per your choice this issue is fixed in v0.3
V0.2
1. No alert popup will be displayed to inform select n save the location.
2. Save the location mode directly by clicking the volume level image.
v0.3
1. Reflect the volume level changes in the taskbar volume icon
2. New mode added "AutoSave", enabling it makes the app save new location automatically with the last volume preference, whenever a new location is found.
PS. AutoSave mode works in Scheduled mode, if you have set the app to run after a scheduled interval with autosave mode enabled and it detects a new location it will prompt a message-box, if you don't give it a response i.e ignore it, it will add the location automatically after 1 min and will dismiss itself.
for users of previous versions:
It will use the already existing database of location settings, just install it over the previous version.
PCBuddy
This app is used to plot all the collected points by the location aware app on google maps.
Unzip the files and then copy the locations.db file from your device to the same folder on your system. Once the file has been copied Run CreateMap.exe this should generate a html file in the same folder. Run that and see for yourself
Please replace the dll in PCBuddy with the one in 64Bit.zip in case you are using a 64Bit Windows
Suggested setting:
For the first time I suggest to keep the interval at around 5 mins so that it can grab almost all the desired locations. once you feel it is having settings for your daily use u may turn the interval to a higher(suggested 15 mins) so that it can apply the volume settings for the known locations.
SUPPORT LATE NIGHTS- DONATE!

No comments???

Great idea !
By using GSM signal to get your position you avoid to use the gps which take more time to get position + a little battery consumption.
We certainly can find a lot of functions linked to this automatic profile/location system
I will try your app

Thanks Vesperial, hope it works out fine

Hmmm
hmmm and I thought this was useful

it is a nice idea
but as a nice addon it would be cool, if it would be possible to add names for specific cell id locations and if the app would be a today plugin

thanks diboze,
well your ideas are nice but since i want to keep the user inputs to minimum i went on this way and about making it a today plugin...hmm i m not sure how to do that with a C# app
but suggestions are always welcome

Great Concept!!!!
Just saw your P.S. that the volume icon will not change accordingly...but it works as intended. (Please Fix) Is there a radius on the set locations? I work across the street from our main mall, is why I ask.
I love this concept as I saw the other O.S. had a similar app. (Sweet Dreams)

Hi djyosnow,
understood your concerns about the radius thing but thaz not in myhands as that thing is dependent on lot of factors like, your disance from tower, signal strength etc. But still you may experiment if you get new location alert in case you are at your office.
n yes this is really nice ~PLUR~

Very good application, specially like me who travel a lot from office to client to mall and to our factory
I will give my comment after i use it...

v0.2 Out
Some modification in GUI and user interaction

Re mohitsapru,
i tested your app on my HD, it worked well
I have one suggestion to ease the way we can use it, an option like 'Save the actual sound profile automatically when a new unknown position is found'
Then we can move without thinking about it but it will be good as an enabled/disabled option.
Good job !

Does this app able to detect the change of location if the device switched off(suspended) by power button?
For example:
1. Save volume setting at location A and location B
2. At location A, press power button to turn off the device
3. Move the device from location A to location B
4. Will the volume be changed automatically (without turning on the device) at location B?

I have run it on my Samsung I900 Omnia and i think it works perfect.
But here some ideas:
It would be great if you can add 2 or more cells to 1 location (Because i have here to cells at home, and if I use UMTS 3G i had another one)
If you write the cell id a little bit greater.
And expert mode were you add name for cells (i see this wish earlier here, too), and can add more things.

Android apk's for IT types

While there are plenty of useful threads out there pointing out various apps, I haven't found one that listed the kinds of apps that someone who works in IT like me might find useful, hence this thread.
Hopefully others can add.
1/
ABBY Business Card Reader - A nice app to take a picture of a business card, them import it into contacts. - It is NOT 100% accurate, it DOES require user input to make corrections, but even so, it is worth the money.
2/
Snap n go - a useful little app that requires a companion app on the PC - basically use a camera to take a pic of windows explorer and touch the file to import viw wi-fi
3/
Office suite - self explanatory
4/
Gingerbread keyboard - what it says, if you type much this is the best by far.
5/
QR droid - 2D barcodes, fabulously useful, learn to use these things, you will need to sooner or later.
6/
Electrodroid - paid version - absolutely brilliant for anyone who goes anywhere near computer or electronic hardware, does far too much for me to list here, from various connector pin-outs to resistor circuit calculations.
7/
MobileBiz Pro - paid version - create quotes and send invoices from your mobile, the complete mobile billing solution, one customer will pay for this truly excellent app.
8/
PC Monitor - paid version - companion to an app run as a service on a PC, stonking app, does just about everything you could require for monitoring and controlling remote computers via GSM, including running command line, booting users, controlling services, monitoring hardware, truly excellent app.
9/
WiFi File Explorer - paid version - file manipulation and exchange between phone and any computer with wi-fi, just open a browser window on the computer. Another superb app.
Just add a 16 gig SD card and fill it with useful apps and tools, magic, never worry about which USB stick hold what again.
10/
Wifi Analyser - does what it sounds like, very useful.
11/
RF Signal tracker - does what it sounds like but for phone / radio frequencies, very useful.
12/
SetCPU - paid app - brilliant for underclocking on demand, which prolongs battery life.
13/
Network mapper - the android version of cheops etc.
14/
SMS Backup + (Jan Berkel) - does what it says on the tin.
15/
Contact Analyser 2 - stops cruft building up with contacts.
16/
GTech Net Tools - another very useful TCP test app
17/
Network Info II - another useful network info tool
18/
Terminal Emulator - does what it says on the tin
19/
GPS Survey - very useful for outdoor wi-fi
20/
Google - Mail / Maps / Navigation / Buzz, very very useful.
21/
Titanium backup - self explanatory
All of the above turn my Galaxy S into a portable office complete with customer billing, plus a portable computer / wi-fi diagnostic toolbox

I would swap 14 for SMS Backup+. It backs up the call log as well and all automatically to your Gmail account.

If you go near a car then Garage Buddy is also quite useful.
There are also some good android ODB interfaces if you have a more modern vehicle.

[APP] Smarttags for any NFC Enabled Phone

I have an Xperia S myself, and with it you get 2 Smarttags. (I bought 4 more)
!You can have a maximum of 4 Smarttags or you will have to use duplicates!
These tags can be scanned using NFC and you can set certain actions to perform.
My 4 tags are setup as follows:
Tag 1: Home
Turn On: Wifi
Turn Off: Bluetooth
Turn Off: GPS
Turn On: Loud Sound
Tag 2: Bedroom
Turn Off: Wifi
Turn Off: Bluetooth
Turn Off: GPS
Turn Off: Sound
Start app: Clock (for alarm)
Tag 3: Work
Turn On: Wifi
Turn Off: Bluetooth
Turn Off: GPS
Turn Off: Sound
Tag 4: Car
Turn Of: Wifi
Turn On: Bluetooth
Turn On: GPS
Turn On: Sound
Start app: CoPilot Live
Now whenever I scan my smarttags with either my One X or my Xperia S they will do the same! it's awesome!
For this however, you will need the Manage Liveware App from the Xperia S
Installation
Method 1:
Download Liveware manager from the Play Store
Method 2:
1). download the attached apk
2). push the file to the phone
Code:
adb push livewaremanager.apk /system/app/
Method 3:
1). download the attached apk
2). Copy the apk to your sdcard from your pc
3). Copy the file into /system/app/ using ES File Explorer, Root Explorer, or some other form. You must have SYSTEM set to Mounted and Root enabled. Check your explorer app's SETTINGS to do this.
Open the new app in your appdrawer (livewaremanager)
- the app will ask to downdload the smarttags app, just accept the download.
- turn on NFC (settings/wireless/NFC)
- Scan your smarttag (you can buy 4 Smarttags for about €15,-)
- ??
- Profit!
! This will only work with the official Sony Smarttags, or a tag with the exact same URL inside it! !
The Smarttag URI's
- taken from Indianl's post
If you happen to have un-used NFC tags laying around in a drawer, here is how to use them with the Xperia Smart Tag app from Sony.
Use an app which is capable of writing custom URIs to NFC tags (NFC Task Launcher is able to do that ) and write the following URIs to your NFC tag:
For the blue tag: semc://liveware/A1/1/NT1/1/smarttags1
For the red tag: semc://liveware/A1/1/NT1/2/smarttags1
For the black tag: semc://liveware/A1/1/NT1/3/smarttags1
For the white tag: semc://liveware/A1/1/NT1/4/smarttags1
!You can have a maximum of 4 Smarttags or you will have to use duplicates!
Have fun guys!
Use the Thanks button if this helped you!

Xperia s nfc tag
Sorry guy , you can have 5 tags , not 4
For the favorite tag: semc://liveware/A1/1/NT1/0/smarttags1
No need to try other digit we have try all possibilities
by the way the couple : Liveware/SmartTags app work with all device include those in 4.XXX include the Galaxy note with NFC chipset (not all country have it)
We are working on our own, with more useful function
PS: the tags for the Sony app’s is the Mifare Ultralight (the smallest size) , but since you want better function (like on/off app or setting) you must buy bigger one aka Mifare classic or Fudan

you will paid your tag 5 to 10 times than the market price if you choose the sony one

the sony tags for 4 is like USD 13 officially from hong kong, but i'm going to try out these underground metro NFC tag from china, I think they will work and the tags are about USD 0.34 each, I know that store value cards do work, so i'm sure the tag coins for china underground will work too.

what are nfc smart tags and what are they used for? Sorry for the silly question but i never heard of them and I am kinda new to all this NFC stuff I have a nexus s 4g with a nfc chip built in?

I am using the way you have mentioned, but if I have a tag which enables GPS and also starts GPS application (Sygic), the privacy policy for gps pops up each time I show this tag. Is there a way to bypass or disable this privacy policy pop up.

there should be an option under settings to prevent the policy from displaying

Thanks!
Your links sectin repaired my tag :laugh:

Video in french on the original thread, feel free to correct my mistakes or help me improve the way this tutorial is (it's my first one)

I'm trying to follow your tutorial, but it is written quite complicated.
Why do I need WidgetLocker?

God bless you, sir. I was thinking of awesome ways to use this when I thought about putting a tag in my wristband. Its completely invisible and more handy than I thought it would be.

Great!
I would like to work with you on monetizing and creatig a business with the app you have created.

This is cool and all, but I'm curious about the practical application of using this. I would think that sliding to unlock would be easier than carrying/wearing an NFC tag all the time.

This makes me want to implant a nfc tag into my palm now...

^^^ yes. Can someone explain or shine some light to what good uses this would bring?
Security????

Hey everyone, sorry I didn't notice the replies sooner.
For the ones asking, this is useful when you don't want to waste time typing your password but still want a kind of security in case your phone is stolen.
As someone said, having an nfc tag in your hand would be the absolutely perfect thing, your phone would unlock just by holding it, and noone else would be able to use it

Well, sure you think that now, but once you've been equipped with your government-supplied NFC tracking implant, it'll all make perfect sense.
Actually...This isn't something I'd use on my personal device, but for the phones in my dev environment, it's a decent way to lock 'em but still make it easy enough for a group of techs to unlock the devices when they're near the bench...

I'm trying to use NFC Task Launcher to control App Protector Pro so that specific Apps can be unlocked via NFC.
Basically the following method:
NFC Task Launcher -> Tasker Task -> App Protector Pro Plugin -> Disable App Protector Pro
But the problem is, the task to unlock App Protector Pro can be called from directly within NFC Launcher. This defeats the purpose of App Protector Pro since anyone can go into NFC Task Launcher to unlock App Protector Pro.
at least a PIN lock is needed to plug this security hole.
Is there any NFC Task Launcher that locks itself?

You could try locking NFC Task Launcher with a different locking app. Keep the same setup but have a passcode using a different locking app to lock it. If you need to tasker can lock apps too. It's a very basic lock but it still works.
Method 1: download a new locking app to lock NFC Task Launcher. Here's one I saw that looked good
Method 2: Lock NFC Task Launcher with tasker
Sorry no links. XDA won't let me because I'm new.
Sent from my Nexus 4 using xda premium

Problem with that is that the given lock app will pop-up once you scan a tag as NFC Task Launcher is utilized.

So cool

If you want, you can try flashing it after BACKUP!!!!
But this is what I did...
The NFC on Lockscreen/ScreenOff MOD seem to first started on this thread: CLICK HERE
So, I kindly asked on that thread if someone could port this MOD so I could use it on my Skyrocket.
Thankfully, one of the developers ported over for me with 24 hours...

[APP] Smart(QR)Tags

Smart(QR)Tags essentially emulates the same functionality as NFC SmartTags and TecTiles by utilizing your device’s camera rather than NFC technology. By scanning a QR code, which can be easily generated on the Internet, the app activates your device to perform user-defined actions such as switching profiles, launching an app, playing music, and activating WiFi tethering, among many other actions.
Now, you may wonder, why go to a QR scanning app, open it, aim it, and wait for the action when you can just perform the action yourself? The answer is, you don’t. Inteks has allowed users to activate the actions just by unlocking the device, shaking it, and aim. The shake sensitivity and duration can easily be adjusted with simple horizontal scales in the app settings. So for all you who stare longingly at your friends and colleagues who just love to show off their SmartTags or TecTiles, you too, can have fun with these tags. Generate a code, set it up with the app, and put it up on the door or the car dashboard. It’s simple.
I have personally been using this app for sometime and I am really satisfied with the results. It works great on my Galaxy S III but is having problems on the SGSII. It might be a bug. Need help with the SGSII.
But with SGSIII its just awesome and helpful. Its like tasker but a bit better.
