Scan for android devices in the area? - Android Q&A, Help & Troubleshooting

Just working on a concept for an app with a friend and I was wondering if technology exists or is feasible to scan for android devices in the area with the same app. So for example, if you and a friend walked by each other both with the app installed something X, Y or Z would happen depending. Mostly just wondering how the scanning would work, I know most phones have GPS enabled and I know most can broadcast wifi, just wondering if this is at all possible. Making the app shouldn't be much of a problem once I know where to go to figure this out, don't know exactly what this action is called, or how to go about it. Thanks!

[Q] Network gps app

I would like to write an app for the nook that would allow you to connect to something like gpsd on the local network and would use that data to emulate a hardware gps. While I'm familiar enough with programming I'm not all that familiar with android development to know if this is feasible. Is it possible to write an app that will emulate a gps and transparently work with things like google maps?
There are apps currently that allow u to use a bluetooth gps receiver with your android phine that emulate and allow google maps to work....
Maybe a good place to start?

I posed this same question the other day, someone just replied and created an app I am yet to try as my nook is rebooting itself today.

android cb radio app

I was wondering if it would be possible to.develop.an android
App that exploits a phones transmit and reciever to make carrierless calls direct
From mobile to mobile.
Sorry if I wasn't clear on the last post.
Let me elaborate, now that I'm sitting at real keyboard.....
I don't know enough about how the hardware in modern smartphones work,
but it seems to me that all phones have the capability of transmitting and receiving signals.
Has anyone thought of developing something that can make use of this without using a carrier in between?
An app that can transmit and receive directly to another mobile that is in radio range.
There are many apps that support various forms of communication without carriers, but they depend on bluetooth or wifi.
I am talking aout an app that uses the phones GSM/GPRS/ETC radio - the one that has enough power to reach a cell tower - only it's designed to be picked up directly by the other phone (provided it's in range).
I guess what I'm trying to find out is if an app can be developed to turn my fancy smartphone into a "walkie talkie" or "2 way radio".
The advantage is free calls when in radio range.Hope this makes sense and someone can point me in the right direction.
You mentioned push to talk which there are apps for that just go to the market and type in push to talk. Although I believe they require a carrier access. Although there's Google voice that if your within range of WiFi. There's free apps called text for free. If you go to related apps there might be something there. I'm not a hundred present sure if its possible. But hopefully with my suggestions it might help you find what you need

I just found the app that I think you are looking its called cb radio chat. It's a new app if you have problems the developer has his email on the description so s/he must have no problems finding a solution to what ever problem you might have.

gps tracking software instamapper needs some modificatios

hi guys , i need to track my kids via a software on their mobile phone but i want this software to work silently ,, i donot want them to know they are being tracked ,,, i tried instamapper on my phone to test it and it is perfect but it is on the application menu and appears in notification bar
i want something like it to work silently and enables me to activate GPS via web command if inactive and donot appear on app. menu and to be controlled via web account other than their google account as i tried samsung dive and i donot know their google password they both have samsung galaxy s II
Nobody who wants to secretly track their children without their knowledge should really have children in the first place... It's also a massive breach of their privacy.

There are many good parrents that would like software like that. but the
Obviously themabda don't have kids, at least not teenagers. Responsible parrents don't let their kids run loose. Being a kid means testing your boundaries. As for the software I would like something similar. So far I havent found one. I did see one for rooted devices but still haven't been able to locate it again. It's somewhere on this fourm. I'll keep looking. It would be useful for locating a lost or stolen device also. The one I found before could turn on the cameras and record audio along with many other features.
As far as an invasion of privicy: As long as I pay for the devices and service I have no hesitation to track equipment that I own, no matter who is using it. If they want privicy let them buy their own. Of course if you're not doing something wrong why feel like you have to hide it?

[Q] App to track family members (with their permission)

I saw another thread about hiding apps in some guy's wife's phone to track her. I'm looking for something similar with my wife, but it does not need to be hidden. Mainly to be used because I commute quite a distance and this would let her know how close I am to home (rather than having me text while driving). Similarly for her when she's travelling.
Just an app that would:-
1. Allow me to see where she is (and vice-versa)
2. Use GPS if on, otherwise fall back on net information
3. Not use SMSes (some sort of internet-based communication between phones)
I could probably hack something up using Tasker but her phone isn't rooted like mine is so the capabilities for GPS etc are a bit more limited (and time is limited, of course).
Thanks!
Already built in

You can actually do this with the built in google maps application. It's called local/latitude. You can share where you are and control who sees it an when. Go ahead and look into it. Much better then downloading another app IMHO.
See here: Google search latitude android
Thanks, yeah I know about latitude features but it seems to lack a way to "ping" the other party with the equivalent of "hey, I've reached road X"

Use an app called Backitude from the Play Store. Latitude updates pretty arbitrarily on its own. This app allows you to control how and when it updates, and also let's another person force an update on your phone by sending an SMS. It's all Internet based except the update triggering part. You can also use the tracking features of Cerberus, another app in the Play Store.

HTC Fetch

These look like they would be fun to have:
http://www.htc.com/www/accessories/htc-fetch/
If they start approaching US$25, I'll probably grab one.
ive got one. its a nifty little gadget.

Mine arrived from Best Buy today. Does anyone know if there's a way to keep the proximity functionality without having the notification always show in the notification bar? I went to app settings, and it's not allowing me to disable it.
in the stock config, the icon is there when activated, just like the nfc icon.

marctronixx, I think I recognize you from a few previous phone forums. :good:
This device sounds like it wold be an ideal 'Trusted Device' along the lines of the Moto-X implementation where the phone lowers its security barriers when paired with a specific Bluetooth device. I've even suggested as much to HTC.
I'm wondering... Have you tried it with any of the myriad of tasker-like apps out there to try to replicate the feature?
hey!
ive only used it as directed, but if you pose a scenario i can experiment with, perhaps i can help you answer your question?
@marctronixx
Big apologies for long delay.
Here is a scenario... There is an app called Pebble Locker that although designed for a Pebble watch, allows any BT device to act as a trusted connection and automatically disables PIN lock. If no Pebble or other trusted device is conected, PIN lock returns. (Unfortunately it doesn't work with pattern lock or fingerprint scan). The idea is that if you have a separate device near the phone, it lowers the barrier. If you leave the device, the barrier rises again. I'm hoping the Fetch would work for that as it would almost always be in my pocket or nearby.
Of course, it would be better if it was something built in to HTC devices. Some time ago I stumbled across their SDK and it seems to be pretty powerful but I'm not a programmer so...
-Separate note: I've seen some discussions that the KitKat update on the HTC One's breaks Fetch. Not too many confirmations, but no denials either.
Hello! I have 2 Fetchs. One for the One Max and One for the One m7. My Fetch works great with One m7 on Kitkat.
Cannot find the discussions... I´m curious

Glad to hear it. I found a couple of places where two or three people reported problems.

http://htcsource.com/2014/02/sprint-releases-htc-one-android-4-4-2-update/
Just search 'fetch' within the threads. I found them today by Googling 'HTC Fetch KitKat not working'
@Faxman, thank you. No Problems here. Fetch and Kitkat does the job. Pi pi pi pi pi pi pi pi
Looks like Best Buy US is starting to sell the Fetch for $29. Looks like I'll be owning one soon.
I got my Fetch from BestBuy (see above) and it works as advertised. Only 75% battery charge out of the box.
It indeed showed up as a Bluetooth device in Pebble Locker (see farther above) so I am able to set the phone to remain unlocked while in range of the Fetch and PIN lock if not.
Now, for all you actual developers out there, here's a link to the SDK for the Fetch. Let the fun begin.
I installed the Sprint OTA KitKat update yesterday and the fetch continues to work... sort of. I've found that if I turn the fetch off I have to go in and find it again and pair again.
I also noticed and downloaded the HTC Fetch app in the app store.
It has a nicer interface and apparently a couple of additional features (including the ability to connect to other BT 4 devices)
It apparently connects differently as you can run it without it being paired in regular BT settings and it doesn't retain the annoying Fetch icon in the notification area. BUT, since it no longer shows as a BT device, the Pebble Unlocker app that I use to simulate 'trusted device' doesn't see it and doesn't keep the phone unlocked.
I'm hoping there will be some interest in the developer community because I think there are some enhancements that can and should be made to either or both of the apps.
For one, I'd like to be able to disable change the tone or somehow further delay the alarms that go off when out of range. I do that far too often. However, when that feature is disabled, it also disconnects the BT connection and as above defeats the trusted device functionality mentioned above.
I mostly want to use it so my phone is secure if I'm not nearby and occasionally use the separation alarm feature if I am in a situation where one or the other might be left behind.
i have not noticed any issues with fetch after the sprint 4.x update. im stock non rooted.
thanks for the heads up on a fetch app. ill go smoke it over...
