How to wirelessly transfer data - Java for Android App Development

Hey people!
I've been developing Android apps for about 4 months now, so I'm still pretty new. There are two apps I am currently working on, and I'm stuck at a similar point in both of them - connecting and sending data to another device wirelessly. In one, I would like to transfer strings (specifically strings of data I've collected from the accelerometer) from the device to a computer via wifi. In the other app, I would like to connect two devices and send the GPS data to each other, so each knows where the other is.
I've done a lot of research, but I'm still unclear what the best way to go about this is. I've seen people suggesting the use of servers for others who were trying to do something similar, but I have no idea how to even start setting that up. From what I've seen, the Socket Android class appears to be what I should use, but I really don't understand how it works. It looks like I connect to a device by providing the IP address, but I don't understand how the other device will receive the data....or really how it works at all lol. Am I on the right track? If someone could give me some explanations/suggestions/guidance I would be very appreciative. Thanks!

I suggest you to download some example then.try to run them

help disabled user reach full potential

I wonder if anybody could help me? What it is, is that I am disabled. My fingers are paralysed, and so working the intricate parts of the XDA is quite difficult. It is not impossible, but it is hard.
I also have several friends who are in the same situation as me. 12 months ago they were given xda 2 each for free. None of them have used them much because they are difficult to use, because they are stuck in their ways, and because I don't think they really realise the full potential of these little devices. It has took me 12 months to get hold of one of these, but just within a few days I'm quite bowled over with the potential.
So I wonder if somebody would be prepared to lead me through making the most of my XDA, with my disabilities, so I can also share this knowledge with the other disabled guys who also have this Pocket PC?
The first thing I want to do is set up the basic software, to maximise connectivity with my home network. I have already started this, and had some help in this direction on this forum, but I am still a bit stuck.
I have loaded this Pocket PC software onto my xda 2 http://forum.xda-developers.com/viewtopic.php?t=17410&highlight=jojo . I have windows XP on my desktop computer. This is hardwired to a 3Com wireless router. I have bought a SDIO wireless LAN card. When you install the software, it virtually sets its self up, the connection displays itself, you select it and have a choice between a Internet connection or a work connection. If I choose work, I am able to connect to the Internet and surf the Internet, but I am not able to do an active sync. I have gone into my start menu/settings/connections/network card/network adapters/socket WLAN SDIO V1 driver /name server and set the WINS to the IP address of the computer I want to connect to as somebody suggested to me, but it doesn't work. I also cannot see the other shared directories on my computer's on the network. (I do have Norton security on, but I have tried these with Norton security disabled.)
Can anyone make a suggestion?
Thanks in anticipation, funny keyboard.

Wifi direct

If you are like me and have an S3 and a Note 10.1 but never really needed to transfer files between the two until later then read on. I wanted to transfer some music from my tablet to my phone without having to transfer to my laptop, then to my phone. So I did some digging and found a program called fast file transfer which sends files using port 8080 to any android device from another android device. It worked great.
But while digging around in my wifi settings I noticed this thing called wifi direct. I wondered what it was. So I turned it on, on both my phone and tablet, found the file I wanted to transfer and hit the share button. Then I told it to share via wifi direct and bada bing, bada boom, the file was transferred. Very cool. Far easier than fast file transfer. So I will use wifi direct for me and others with Note tablets or S3's and fast file transfer for the other non cool android people.
A bit of a newb moment? Maybe. But I never had the reason to use this particular feature until now. So I just thought I would share and throw this out there, maybe it could help someone else in the future. It was kind of fun to do also.

Well its news to me as its not something i ever bothered to look at in the past .
Useful to swap stuff phone tablet etc .
jje
I found it awhile back much the same way you did and you are correct it is very good and reliable.
Athough WIFI DIRECT works very well with file transfers it is limited to files only. The solution to this limited ability I found is a app called Software Data Cable which allows you to transfer complete folders not just files. It can be found here

Thanks for the link, I will check it out.

This sounds like a use-case for a Wifi Direct file management app. I use HitcherNet to transfer files between my devices over Wifi Direct. It gets speeds up to 30 MB/s and is solid. You will have to check if your device is supported.

Dev question - remote communications with N4

I'd have asked this in one of the dev forums, but this doesn't refer to a current app. It could down the line, but not now. So I hope this is the right place. I gather that it does from the intro posts for those forums.
I need to communicate with a N4 from a remote device so that it has some information that it would use under certain conditions. The remote device could be another mobile device or a computer. This may require that I develop an app for the N4, but it's very possible, maybe even likely, that Tasker could be sufficient for these needs. The need may be to push some .mp3 files to the device or indicate to the device which of a set of .mp3 files are of immediate concern or to pass along some programmatic values to the N4, which would then respond accordingly. Those details probably don't matter that much at the moment. It's more about communicating between the devices than what the communication happens to be.
I could upload files to the N4 via ftp as long as a server is active on the N4. Not ideal, but potentially doable. Some other wifi communication could work, too. I suspect that the N4 with Tasker could act upon a SMS message with certain content, too. I'll look into that. But I'd prefer not to be dependent on a network connection as it may not be reliable in this case.
Is there any way that a remote device, be it another mobile device or a computer, can directly communicate with a N4 without benefit of wifi or a mobile data connection? In other words, a straight peer to peer connection?
Any info about what forms of communications are potentially available would be very useful to me.
Thanks.

Thanks. I'd like for that to work. I've had trouble making successful pairings and when I have made them, I've been unable to make reliable bluetooth communications between devices. I gather that I'm not the only one who has encountered such issues. But I'd like to think they're surmountable.
I had trouble getting my N7 and N4 to pair, but that was probably my own fault. I have them communicating now. File transfers are slow, which could be an issue for me. But there are ways around that in this case. I'll play around to see how consistently reliable it can be for me.

my n4, n7, and gnex pair very well together. via bluetooth not being as fast as a connection as a wireless hotspot, but the connection is solid.

Good to know. I think the problems I had were due to my own errors. It seems good now. Just over 100 kb/s transfer rate, though. That's too slow for some aspects of what I need to do. But I can work around it by having the larger files on the remote device all the time and just let it know which of them to use based on variable values.
Any reason why I can't program one device to transfer files to another via bluetooth? It's easy enough to use a file manager for this, but for the purposes of this project, it would be better to do it from an app interface in which the user makes a few choices and submits them. Then, the appropriate file transfer takes place. It's a proof of concept. In the ultimate application, a file manager wouldn't be appropriate, so we need to mimic that to a simplified degree now.
I'm a dev, but not much of an Android developer, so I'm either going to learn on this project or get someone else to do it. So I am partially in the dark on some of these matters.

you should be able to program one device to send to the other via bluetooth, there shouldnt be any restrictions.
How about setting up an SSH server on the nexus 4?
That way you could manage it remotely, even if you're away from home.

There's no need for a connection from a remote site in this case. Somewhere within 150' maximum is fine. But even Bluetooth range is quite adequate for now. SSH would require a wifi connection, too, which may not always be available in these circumstances.
I will probably go with Bluetooth for now, even as slow as it is.
Is it possible to connect two devices via a USB cable and communicate directly that way? Would they recognize each other?

[Q] Active FTP Connections Not Working

Hey all. I recently purchased a Verizon Samsung Galaxy S4 32GB and have really enjoyed it. Today I ran into my first issue, and boy its a doozy. Apparently I'm not able to make a solid connection to FTP servers using Active FTP. If I switch to passive, everything connects fine. When I switch to Active, it connects to the FTP server, but is not able to retrieve the directory listing (Filezilla error on laptop) and on my phone it states "425 Could not open data connection to port 48891:Connection timed out". This is replicated on my laptop (Through Mobile Hotspot) and on an ftp client on my phone. I work in IT and use my mobile hotspot as an external network when we need to rebuff a vendor's claims that our network is the issue (I'm sure those of you in IT also can appreciate the pain of having a vendor blindly blame your network instead of fixing their own problems).
Verizon claims that it does not block any ports. Samsung has stated that they do not support this issue, but I talked the supervisor into filing an engineer report (If that will even do anything) even though I won't hear back from them regarding this. So I am hoping I can get some help from the best android community out there!!!
Has anyone else tried to make an active FTP connection from a Verizon S4?
Would anyone be willing to give it a try?
UPDATE:
Well the Verizon guy did some testing for me (Kudos to VZW). They dont block ports, but they also don't forward the return connection for Active FTP. If anyone else wants to give it a try and let me know if it works for other providers, it would be appreciated. I may have to just fork out $$$ for a Public IP on our VZW Jetpack.
Remember that most carriers use CGN (Carrier-grade NAT) on their network, specially for mobile phones. While CGN is supposed to be stateful, Verizon probably has a broken implementation as it doesn't redirect a port to your private IP (something done in Linux by using the conntrack_ftp module). Anyway, using non-passive FTP is almost always a bad idea if you don't have a public IP. Sticking to passive is your better option.
I wish that was possible unfortunately the vendor is using active FTP for his application. I am testing to see if the internal network is the cause of the connection problems we've had. To get him to move over to passive since it is better

Use android as usb wifi dongle/5GHz ability

Is there a way to use android for the wifi capabilities such as a dongle? Basically my laptop only sees 2.4GHz and I could buy a dual band dongle or upgrade the network card, but my note 5 is rooted, has 2.4/5/AC capability and a usb even lol so Id think itd be possible to plug phone into pc and have pc recognize it as a wifi adapter which would allow me to analyze the network with all the capability of the phone. I can nly find results of tethering which the pc recognizes as a ethernet connection which wont enable being able to see the wifi ssids that the phone can.

Theoretically, yes.
You would need an application on your phone and one on the laptop.
The application would take over your laptop's wifi control and hand it over to the app on the phone.
Afaik, this pair oft apps does not exist.
And I think it's not worth writing them.
USB Wifi Dongles with 5Ghz cost like 20 €/£/$.
So
Effectively, no.
I figured but really, everybody has a phone if this was an option even for 5-10$ it would be a better one then having to go out or get on amazon, read reviews and purchase a dongle that may or may not satisfy. If it was able to be done on a phone more then likely there is one with anybody that gets on a pc/laptop and if it was as easy as plugging it in to use it as a wifi dongle, not tether but an actual wifi adapter itd be like the next great thing, not like that bluetooth tethering they tried but like the end to usb wifi dongles I think anyways. Besides with all the ridiculous apps that do cost money on the play store i think somethin like this would be in the top most purchased. plus idk how the licensing works but with it actually being a internet connecting app it would be hard to crack the apk as it would be required to have full contact with whatever servers authenticate the purchase. I would think anybody that worked with networking would have it as a must have for work as its one less thing to carry and should be somewhat simple plug and go plus the countless people who are someday buying a dongle there would be no need to.

Nah, there'd be like 0 to 4 people on the planet who'd actually pay for that feature.
Cause from pro to noob, 99.99999% are fine with regular USB tethering or BT Tethering! If they have to change the wifo network, they don't need to change the Wifi network using the mouse. They just grab their phone. It can't be far, it's connected to the laptop, just follow the cable
Anyway, most people don't even know they can do something else with their phone besides Whatsapp, Facebook, Snapchat, taking pictures and dropping it cracking the screen
Already heard of a thing called routing tables? Just because something is connected to the internet doesn't mean it will reach a certain server. How do you think your Adblock works? Exactly like that
People who work with networking use ethernet cables. They have Ethernet plugs all over their workspace. They often don't usw wifi at all at work.
If you still think it's ka and ching, then go ahead, learning to program is always a good idea!
*if this end up looking fantastic its because I tried the increase indent option in an attempt to figure out how to paragraph on this*
Lol will I know for a fact itd be like, whoever made that app now has some change in their pocket and it goes jang a lang a lang. I unfortunately do not know the programming knowhows, though think I could learn it if I put myself to it, by looking at how some of them are written it looks pretty straight forward once you got the jist of it down, I just dont got that and it kind of overwhelms me trying to figure it out without any knowledge of it. But, you are right, at least without maybe google play promoting it or some type of advertising that would show it as being in place of a usb dongle it would probably get buried by the countless apps made each day which btw all are not great (some are ridiculous) yet they are there.​ I am sure root would be needed for an app like that, which would detract from the audience as well. but the need for usb dongles is nowhere near a thing of the past, in fact I'd say it will only become more of a thing to have especially for the ones that would rather get it instead of buying a entire new system. With technology today and the transition from wired to wireless it would be the last option for anybody that doesnt have wireless before they have to update a whole system so more then likely they will opt for the 20$ dongle. I do consider myself one of a kind and like harry potter special (joking) but if I really am the only person to have tried doing a wifi heatmap on a laptop that only had 2.4 ghz capabilities then either i am broker then everybody else or I am just not from this earth.​With all of the things you are able to do with a phone, use it as a bootable usb to boot a system (drivedroid), foxfi tether, wbnr wifi hack) youd think with a few changes of the programming or combination of the 3 this would be something easily done. I take it your familiar with programming? It seems you are and thats in a compliment kind of way, none of this is in a disrespect or disagreement with you at all, i just am uninformed in the category, but how long approximately does it take to say program an app that would be like a screen mirror app or even simple notepad app? These days if given the choice of buying a 20$ vs anything above and both have the same end result the 20$ is going to fly off the shelf. Of course these arent hot cakes but in any given situation when paying for less is an option and getting the same thing is the result i mean it is hard to think it wouldnt become popular. Drivedroid lets you use phone as bootable usb, i have countless usbs but it is just so much more convenient using my phone as its usally in my pocket already and convenience is what takes the cake​.

Whoaaaa.... Sorry but too long to read...
Maybe THIS will convince you:
1. Almost any phone uses USB 2.0
2. Phone's USB Speed is limited due to the USB speed not being the manufacturer's priority (Ever been annoyed about the slow transfer speed of files to your PC?)
3. 2.4 GHz Wifi already gives you 54 to 160Bit/s.
That's a speed, you'll NEVER get through your USB connection.
Be really happy if you get 40 MBit/s...
4. There are... like no wifi routers which support 5GHz only.
5. There are no Laptops without any wifi except in a museum or in the big spare parts box in my garage.
Who'll buy it?
1. People who don't have wifi in their notebook?
No, they sit in a museum or they just use regular USB tethering.
2. People who want faster network connection?
No, cause it won't get faster.
3. People who are in an area with 5GHz wifi only?
No, 5Ghz only makes no sense due to its bad signal through walls. This just doesn't exist.
4. People with old hardware who have a broken wifi chip in their notebook and who can't afford a dongle?
They would use regular USB tethering. If they can't afford a dongle, they can't afford your app.
5. People with very few space in their pockets, to few to carry a thumb sized wifi dongle?
No, they use Bluetooth Tethering. They probably also have a wireless charging phone cause they also don't like to carry a cable.
6. People who are allergic to Wifi dongles or who are forbidden to buy them by their religion because the dongles aren't approved by their guru whereas mobile phones are?
Nooo, they just use regular USB Tethering. They live in the guru's house, they may not leave it, so no point in having an easier way to change the wifi network. Besides, the only laptop in the guru's home is his own, cause his followers may use the internet only once a week, so one notebook is enough for the whole lot. And Guru is rich enough to have a new notebook with integrated 5 GHz Wifi.
AND FINALLY: HOW OFTEN A DAY DO YOU CHANGE YOUR WIFI NETWORK?
ONCE OR TWICE
Use regular USB tethering and pick your fnjörpliging phone up to change the network, there's absolutely no need to have an app for that!
So, I had very much fun trolling you with facts! I even got to make a joke about a funny made-up religion.
I'm outta here
Well after that post it all kind of makes sense to me now. You either are not that informed about 2.4/5ghz radios, you live somewhere that it is not popular... yet. Not sure if you understand what heat mapper is referring to, its only the signal that matters not the speed but if speed was an issue you kept up on any tech news lately or hear of somethin called usb c? 10Gbps. 2.0 gets 480Mbps or 60MBps which would be plenty and would undoubtedly be better then usb tethering as it would have direct and complete use of the wifi connection.
So almost any phone USED to use usb 2.0, like almost any computer USED to dial up to connect, wondering if you might still be, (jk). Just like it always has and will tech changes and soon they will MOSTLY have usb-c or 3.1 and speed is out the window. And finally, r u familiar with play store and its contents? They have some quirky things that become instant hits (flappy) or this app https://play.google.com/store/apps/details?id=org.prowl.torque that you connect the phone to the cars diagnostic connection obd and has 1 million users at 4.95$ each. With your thinking all if those people would never have got that app and would use the normal regular mechanic tool to read odb errors.
And last but not least your comment was just as long as mine. And i read it, out of respect. If u want i could send you a little like 5 step process on what its all about and a song to go with it that even spells it out. all in fun and respectfully debating of course. I go to school for this stuff, not that u dont or havent but definitely was skipping the day they spoke of 2.4 and 5 and the heat mapping of each.
Which is ok, i was wondering cuz yes i am too cheap/college student to get a pc just for that 5ghz. I needed it to completely do my heatmap as the router is 2.4/5 simultaneously (prepare for that, most of them are these days wont even mention ac) but only seen 2.4. Anyways from the sounds of it you dont like to read long things which explains some things. If u do please know i say all of this in a friendly sarcastic way, with honesty behind it just definitely no disrespect more friendly joking.

Whoaaaa.... Sorry but too long to read...
Maybe THIS will convince you:
1. Almost any phone uses USB 2.0
2. Phone's USB Speed is limited due to the USB speed not being the manufacturer's priority (Ever been annoyed about the slow transfer speed of files to your PC?)
3. 2.4 GHz Wifi already gives you 54 to 160Bit/s.
That's a speed, you'll NEVER get through your USB connection.
Be really happy if you get 40 MBit/s...
4. There are... like no wifi routers which support 5GHz only.
5. There are no Laptops without any wifi except in a museum or in the big spare parts box in my garage.
Who'll buy it?
1. People who don't have wifi in their notebook?
No, they sit in a museum or they just use regular USB tethering.
2. People who want faster network connection?
No, cause it won't get faster.
3. People who are in an area with 5GHz wifi only?
No, 5Ghz only makes no sense due to its bad signal through walls. This just doesn't exist.
4. People with old hardware who have a broken wifi chip in their notebook and who can't afford a dongle?
They would use regular USB tethering. If they can't afford a dongle, they can't afford your app.
5. People with very few space in their pockets, to few to carry a thumb sized wifi dongle?
No, they use Bluetooth Tethering. They probably also have a wireless charging phone cause they also don't like to carry a cable.
6. People who are allergic to Wifi dongles or who are forbidden to buy them by their religion because the dongles aren't approved by their guru whereas mobile phones are?
Nooo, they just use regular USB Tethering. They live in the guru's house, they may not leave it, so no point in having an easier way to change the wifi network. Besides, the only laptop in the guru's home is his own, cause his followers may use the internet only once a week, so one notebook is enough for the whole lot. And Guru is rich enough to have a new notebook with integrated 5 GHz Wifi.
AND FINALLY: HOW OFTEN A DAY DO YOU CHANGE YOUR WIFI NETWORK?
ONCE OR TWICE
Use regular USB tethering and pick your fnjörpliging phone up to change the network, there's absolutely no need to have an app for that!
So, I had very much fun trolling you with facts! I even got to make a joke about a funny made-up religion.
I'm outta here

Also the internet provider gives you the speed not the 2.4 or the 5. And more importantly the ability to see the 2.4/5 channels is what i was needing which in a setup if you have alot of people connected to wifi by splitting it with some on 2.4 and some on 5 you would have better connectivity vs everyone on the same one. If somebody wants speed and speed alone a dongle, wifi or bluetooth wont even be on their mind , they will be hooking it directly with ethernet as thats the fastest and best option there is.
Also look in this network forum like 4 down it says usb reverse tethering and has like 600,000 views. Read that description and see if you still think this would be useless. With your logic ud have to wonder y they even have a phone in the first place. But its obviously popular. Mind/openit
