Hi XDA. I am a CS undergrad and for my final year project, I am looking forward to make an android app that records the cellular network's signal strengths at different locations where its user's daily interaction is, for example work, club, home for one person and school, home, [some other place] for another. The app will be designed to use an algorithm that will also combine similar locations by multiple users into a location group or a region. After collection of a significant amount of data, (say 1,000,000 entries) for a particular network, The app, as well as a web interface, will publish the results, comparing the service quality of different cellular networks, helping the users to choose the best for them according to their roaming needs, increasing the ease in their mobility.
My question is that is it a good Idea? Given that from where I belong (Pakistan), cellular network signals are still a big issue. I would also like to know if some developer in the past has worked on something like this or any thing related to it.
I'll be looking forward to the responses.
P.S: Sorry for this vague description, feel free to ask me any question about this Idea.

I just bought a Samsung Galaxy Player with the intentions of using it as a wifi phone as a replacement for my cell phone.
The main reason for this is I don't like all the tracking going on with cell phones. Cell phone tower tracking, Carrier IQ tracking, etc., etc. I'm not doing anything illegal and I'm not a conspiracy nut, it's just the principle of it. I'm an American - I'm suppose to have freedoms and be able to have my privacy if I so choose.
I had planned on using either Skype with an online phone number or Google Voice to get voice on my Player. The problem with this is Google is going to track every wifi hotspot I log in from so I'm kind of back at square one - EVERYONE wants to spy on you these days. Not to mention all the criminals trying to get personal info at public hot spots.
So I thought about a VPN. That would stop Google/Skype from tracking the wifi hotspot I log in from. But, how does one find a VPN service that you know without a doubt is trustworthy??? I've even thought about getting my own VPS and installing OpenVPN myself (found a good service for that if anyone is interested). But from a true anonymity standpoint it would be better to use a VPN service who has many other customers all using a shared IP. Plus I'll use the same VPN service for my desktop and it would be nice to log into some websites from another countries sometimes.
I've also looked into setting up my own Asterisk server but haven't had time to get too in-depth with that yet.
Any thoughts or ideas would be greatly appreciated.
That's a bit much. I think skype is safe, though.

Thread moved to Q&A due to it being a question. Would advise you to read forum rules and post in correct section.
Because I am a "noob" and not allowed to reply to any topic except this "General" Forum, here is my question. WP7 public API cannot query the phone hardware to determine how much data traffic has occurred on a specific network adapter (ie: 3G network) so we cannot have a simple app such as 3G Watchdog (Android app) to monitor how much data we have used? It is stated that carriers would have access to this sort of data, but what I have seen so far is Apps specific to carriers that log into the account and "extract" this information. This is unsuitable:
1) In every case I have seen it uses that carriers mobile network to poll their site, so actually increasing the usage of their mobile internet
2) The carrier site is always significantly behind the actual usage so you would probably go over the limit if you are trying to run close to the limit
There is reference that WP8 will be able to do this, is there any real knowledge of this or is it just a wish and a pray that MS get their act together and allow this low level system interrogation? WP7 has many updates, so is this something MS could package into an update and fix now? I take it there is no other way to get this data (SNMP type network traps and polling springs to mind)?
My son has WP7 (from Android) and this is pretty disappointing that something as simple as monitoring his interenet usage is so cumbersome. Reading other forums and expecting corporates to load this software, specific to a carrier, configure it with corporate account information and release it to employees is also pretty mind boggling.
Hi all,
This probably belongs to the development forum, but since I'm new to XDA I'm only allowed to post here.
My question is about seamless mobility between WiFi and cellular. This seems to be a rather hot topic, with a lot of interest from cellular operators and many ongoing activities in various standardization bodies. However, in reality, till any of these standards get actually deployed in the field the problem of providing uninterrupted experience to the user lies in the hands of mobile app developers. Hence the question - are there any tutorials, samples and best practices the mobile app developer can follow to ensure seamless experience for the user when the phone moves from WiFi to cellular and vice versa?
Ultimately, I'd like to learn how would it be possible to write a Skype-like app to survive the switch to/from WiFi.
Hello everybody,
I have a dream, a library for developers to make better location-aware-down-to-the-room apps. For free.
I have been experimenting with indoor positioning methods.
While tracking users indoor is largely an open problem, telling users which room they are in is simple. My prototype have shown that K-nearest-neighbor on Wifi signal is already a viable solution. It reached 90%+ accuracy, at least in my college lab. It can even partition a large area, pretty impressive. (Probably due to the large number of hotspot around college). If you're around the room edge then it might report adjacent rooms.
So far it looks promising, I am thinking of creating something like wikipedia. Open source, free to use, no ads. It is mutually beneficial to use and contribute to the same platform. However, the fact that there isn't a open wifi-signature positioning database out there suggests that I might be missing something.
Your thoughts?
(Attached my prototype, feel free to test it out. Don't go crazy yet, consider this v0.01 alpha.)

I have an HTML 5 app built with Sencha Touch + Cordova. The app works ok and is already in production, but I want more in terms of performance for the future, so I'm thinking about rewriting it in another framework.
On propertycross.com some of the most used cross-platform frameworks have been compared... I went through all of them and for me the winner is with no doubt NeoMAD. The approach seems the right one: write in one language (Java) and have the native app generated for each platform.
I saw no difference in terms of performance between the native one and the one built with NeoMAD, also the app was only a bit larger (1.2mb the native one, 1.9mb the one built with NeoMAD), with Titanium and Xamarin I get an app 10 times bigger, not to mention the increased startup time.
By doing some research on the web though, NeoMAD doesn't seem much used... on stackoverflow I get only 5 questions with the neomad tag.
So why so few people use this framework? Seems to me the perfect one... Does anyone have any experience with it?
Hello Emanuele,
First of all, as one of the NeoMAD founders I was very happy to read your post!
To answer your question, I think there are 3 explanations:
1/ NeoMAD is available on the market since 2012 only and this is a first objective reason why we do not have a lot of users at the moment.
2/ Neomades is a small company with limited marketing resources compared to our main competitors.
3/ The Neomades team is mainly a tech one and we have not been so efficient until now in business dev.
However, NeoMAD is used for mobile developments by major french organizations such as CROUS, L'Oréal and TNS Sofres / WPP Group. Some of these applications are available on the app stores, you can find more information about it in the References section of our website.
We hope that comments like yours will catch the community's attention and increase the visibility of NeoMAD… without users and the developer community we will not succeed !

Best regards.
Hey @memanuele
First of all, you need to choose the framework according to your specific project needs. It's really hard to name the one-fits-all framework. If you're in no hurry, you can spend some time trying different ones and thus deciding what will be the best variant for you.
If you don't have time, you can get initial information from the blogs, for example, here or here, to name a few. Google it, there's alot of interesting going on.
Edit: Ddamn, just noticed the date of the initial post...
