[Q] WiFi Direct question for noob - Other Tools & General Discussion

Hi All
I have an app idea for transferring data using Wifi Direct but I actually don't know if it's feasible because the data should be transferred automatically without the need for a user to accept or authenticate the connection. Essentially it would be up to the app to take care of that.
Is that possible?
A couple of other questions:
1. would Wifi Direct be able to work on a mobile device if WiFi was also switched on?
2. would it be constantly scanning for other Wifi Direct devices if switched on?
Thanks in advance for your help.
(If this would be better placed in another forum/subforum please let me know.)

[Q] Possible to use Android without any data plan at all?

I'm sorry if this has been asked already.
I'm very interested in getting a Samsung Vibrant. I wasn't a big fan of Android at first, but it's really growing on me. However, I have absolutely no interest in getting a data plan -- Everywhere I frequent has open wi-fi. If I got the phone, I know no carrier would let me leave the store without a data plan, so I'd just get one on eBay.
Is it possible to completely disable data, contact/email syncing, cloud connection, etc. and still use the full capabilities of an Android phone through wi-fi without screwing anything up? I've heard that if you don't have a data connection it's possible that your contacts will delete themselves when the phone tries to sync -- Is this true? Is there anything I should know about using Android without data, or are there any apps I should get to help with the whole process?
I have no data plan at all, G1 on T-Mobile. Vibrant shouldn't give you any problems, but if you're worried about contacts deleting (which has never happened to me), you can turn sync on and off, so just toggle it when you connect to wi-fi. Glad to see more interest in Android, hope you can make some contributions to the community.
Thanks for the info -- I didn't know you could actually toggle the syncing!
I hope I get more into Android, too. I'm a huge Windows Mobile person right now, but after looking at the Vibrant, I think I've been converted.
I also hope I can help in the community a bit, too -- I've been coming here for a long time, and I think you guys are amazing at what you do.

I'm sorry, I've got one more thing to ask: So can you disable ALL data, except for the phone data (calls, texts, etc.)? I can actually still get apps and do pretty much everything data allows all through wi-fi without any issues?
You can do syncing/cloud connection over WiFi too.
Thee other say my wife forgot to pay her bill.they shut her phone off.. Connected phone to wifi in the house and was able to use google talk email market... No text or calls though
Sent from my PC36100 using XDA App
well i had a first gen my touch 3g, i unlocked it and put it on att. what i endened up doing was i set up a different apn and since the settings were wrong i couldnt get on the internet. i could be wrong, but i think thats what kept me from getting on the net with it. and then i realized i had a data plan on my contract so i put the correct info for the apn and got data.
U can delete all your APN Info so that your phone will not be able to connect via 3G or Edge only with WIFI ;-)
Have fun with this great os!
There is literally an option in the network settings to disable the "mobile network". This disables internet/3g data traffic but does not affect call/text (that is not considered "data").
Also, Android actually disables the mobile network connection when Wifi is active (at least on CDMA devices)
Awesome, this is exactly what I was looking for. I have no idea why I was told it wasn't worth using Android without data - This all sounds like just what I had planned to do. Thanks, everyone! :-D

Relying on that alone won't work as soon as you get in the car with the phone...when it loses the wifi connection, it looks for a cell data connection again. You are right though, so long as it has a wifi connection, it doesn't look for 3G data at all.
People say it's no use having Android without data because there's literally TONS of awesome stuff you can do with data (Google Maps walking turn-by-turn, for example. And Zombie, Run!, which is the best game ever made). But if you're like me and are cheap/broke, or you just don't see yourself using data much, you'll be golden. But I think as you get into Android more and discover what you *could* be doing, you'll want to add data. I intend to put data on when I upgrade
i dn't have a data plan and when i attempt to use a data connection w/o wifi i get an msg from my provider (asking if i really want to and telling me how much it will cost). If your provider allows you access to their data network without you agreeing and then charges you that's pretty bull**** and i would definitely switch providers.

[Q] lost galaxy s3, no internet connection on, no security apps preinstalled

hello, everyone!
my bad if this post is misplaced but couldn't really find a good answer to my specific problem.
basically, i lost my sgs3 today. it had no security apps like android lost, lookout etc. installed and neither wifi nor mobile data were on. have installed from my desktop android lost, but since the phone has no internet connection i don't see how this app can ever be pushed onto the phone.
so basically, my question is if there is anything to be done here? perhaps any code or instruction sent by sms that would trigger the mobile data on!!! i don't suppose so!
anyway, whatever you might think of, i'd appreciate any help!
i'll call the gsm provider at some point to deactivate the sim, unless i can find a way first to locate the phone using their network signal.
many thanks!

[Q] Disable WI-FI to Cellular handover (wifi to data fallback)?

Hi there
As you know in lollipop this fall back to data feature exists if the wifi connection has no internet(officially called "WI-FI to Cellular handover").
Has anyone investigated how does the system check for internet connection on wifi? It must ping something on the outside world.
Whats more important is there a way to disable this feature so that the system behaves like in kitkat?
Thanks

It pings Google's servers.
I don't understand why google hasn't offered a switch(on-off) for this. I can imagine some situations where this is quite bad. Imagine you have a small data plan and you use wifi to download stuff and suddenly wifi stops reaching the internet so the connection falls back to data and all your data plan is vanished in just a few minutes.
There must be a switch for disabling this feature.

Just turn off data? lol
enable wifi-> remember to disable data
disable wifi-> remember to enable data
why do this shi" every time you switch to&back form wifi when you can set it ONCE for all, and let it work as it should!!

I always did it since GB so no big deal to me I guess lol, could be annoying for others.
still annoying
It is some time later but I have a particularly annoying issue with this, nothing to do with data volumes. I used to really like the feature but recently I have had to use gconnect on an internal network to sign in, by the time I have signed on the network is on 4g and he request doesn't go through. Annoyingly now I need to disconnect mobile data in order to login to my companies wifi.
Just a little inconvenient. I dont suppose anyone has a better solution?

[Completed] Use WiFi as phone Hotspot (not data)?

Hello, im just wondering if there is an app for Root or NonRoot devices where I could use the available WiFi and transmit it out of the phone like a Mobile Network Hotspot?
The purpose of this is because I cannot connect my New 3DS to my collages WiFi as it required an Identity, Anonymus Identity, and a Password, Im only able to type in the Password but nothing else and that doesnt work. I could use my phones hotspot but I only get 1GB of data per month, so i don't want to waste it.
Long story short/In other words, is there a way i can use my phone as a Hotspot/WiFi but use the WiFi Network it is connected to instead of the cellphone data.
Similar on how you can use a Laptop as a Hotspot with its own Password aside from the Network one.
Hi!
I'm not having luck searching on this issue, since every result involves data. You will need to ask about that here,

Good luck!

Share wifi over mobile data?

Hello. I have this weird problem. I have an app that does not work over wifi (it's coded, everything's normal). But in a weird situation that I am in, I need it to use it via wifi. So is there a way to somehow trick my phone into thinking that it's using LTE connection, when it's actually connected to my home router wifi?
The problem is.. Phone is not rooted and cannot be.
The approach I'm thinking of: using another phone (that I could root) to somehow reverse mobile data connection in order to create LTE/3G hotspot that shares... wifi. But whenever I google a solution for this, I always find myself finding tutorials that show how to share mobile data over wifi (so.. the opposite of what I need). But I wonder if that's even possible.
I heard about femtocells, but I was trying to avoid spending money on hardware that's going to be used once.
Also, I spent a whole day trying to use an emulator that would allow to spoof mobile connection. Apparently, application creator has blocked the ability to run application via emulator. So unless someone knows how to go around this little situation, this way doesn't work.
