Bluetooth Voice Conferencing - Android Q&A, Help & Troubleshooting

Hey guys,
I'm hoping there's already an app developed that's at least similar to what I'm looking for and if not I'm looking for some guidance on my best method of accomplishing this.
Basically, me and a few of my friends play airsoft pretty intensely. We would like to setup a basic communication system for our team. At least 4 people and we are almost always within 100 feet of each other but we would like to able to get this to a minimum of 500 feet for outdoor fields.
We need the voice communication to be almost instantaneous, if there's a few seconds lag or even a second it could defeat the purpose of us being able to alert each other when someone is heading their way.
There really are not other requirements. We just need to be able to have 4-8 people talking together at the same time with headsets. I was thinking that my best method would be using Bluetooth headsets and using Google Talk or Skype on our phones. I have not yet testing either of these methods. Seeking opinions to see if anyone has already tried this.
Any ideas or better suggestions?
Thanks,
Adam

Recording calls with XV6800

Hi all,
So I've been searching everywhere for information on recording calls with the XV6800. In my line of work I frequently have need to record conference calls for reference. In all cases all parties are aware (even though most states don't require that all parties be aware.) I currently have external hardware to do this, so it's not like I'm being restricted from doing it at all, I just really want to be able to use my phone to do it when I go on site. Taking my phone only is much better than taking my phone and a cord and a recorder. It's a small hassle, but it's all the more annoying because it doesn't have to be. Apparently, some idiot along the way decided they were going to impose what they thought people should be allowed to record rather than what the law allows and the result is, that from all my searching on the net, it seems that the XV6800 can't record because someone somewhere might violate a law from one of the few states that have laws against recording without all parties' knowledge. No software solutions seem to work at this point (although in my mind, if you go deep enough into the system, you should be able to use a software solution. I mean the sound data exists in there.) However it occurs to me that this may be something that can be fixed with a ROM flash. Does anyone at all have any information on this. One of my colleagues uses a Treo and he is literally able to record our calls right from his palm. It must be possible to the same with the XV6800 somehow. Any info would be appreciated. Thanks.
Hopefully someone with "BT stack" knowledge might be able to help with this. In theory the Bluetooth stack could be modified to reroute the earpiece audio channel so that it could be captured. I know at some point DCD and No2Chem did something with changing some of the BT audio properties, but I don't know if they actually got into the guts of the BT Stack itself or not.
To get more background knowledge on audio recording problems with some HTC devices, you can do a search for threads written by the moderator Menneisyys who wrote several well written, in-depth articles on this HTC limitation about a year ago.
Did you try Resco Audio Recorder? I'm not sure if it records both sides of a call as that may be a carrier limitation.

I have. Actually, I've tried pretty much every piece of software available out there already as this is something I do often enough that I really would like this feature. I think nothing that existst now is up to the task and it is going to take someone with serious skills to do some creative programming to get it to work. Did they really program in a hardware block just because some states require two-party consent? I mean that's just the dumbest thing ever.
To jamesjay: Thanks, I will go check those out and see what they have to say.
I would love to have this also. I'm starting up an insurance company and it'd be awesome to have a cheap way to record every conversation. Even if I have to have some type of bluetooth thing to intercept the conversation.
splice into the audio cable and rerout to recording device
Well I have a physical device already and it works just fine. I can record calls if I bring along an extra wire and my recorder, but I don't want to have to do that. I should be able to have a software solution, and I'm actually pretty annoyed with the company for purposefully blocking that ability.

Crodney - I suspect they wanted to avoid ANY possible lawsuits.... Recording outgoing conversations without the callees consent is taboo in most states.... But I agree - there has to be a workaround.... Like a .dll that can intercept the audio and split it so you can record it AND listen and talk.....
here's a roundup of the legality of call recording...most of whats in this thread currently is misleading or false:
http://www.callcorder.com/phone-recording-law-america.htm#Evidentiary Issues
Search for a program called LivePVR. I'm at the bar and posting from my Titan, so I don't have the link. It should do the trick.
Laws regarding recording phone conversations can vary from locality to locality. I know that here, it is legal as long as ONE party knows that they are being recorded.
Only solution I found
When I first go to Telus I asked specificaly to have the possibility to record voice calls, as I oftenly get on conference calls while on the road with no possibility to take notes and I have to write meetings minutes concerning really technical matters.
So they recomend me the P4000, and after 3 weeks of searching, they told me it's too late to change phone now (more than 14 days), so I bougth my self a new Palm Tréo 755p and with CallRec it's like a walk in the park.
I had to pay it my self, as I had the authorization from my company to buy the P4000, but it wasn't delivering what it was supposed to.
So now I'm stuck with a brand new P4000, that nobody wants to buy!
Love Telus

[Q] How can I remotely control the 10.1 Tab

I have just bought one for my dad, who needs my help quite frequently for basic functions. Is there an app out there, that I can use to see and control his screen. The only simple one I have come across is webkey, but that will only work for rooted tabs. Being remote, it is going to be a real challenge to root this, so just curious if anyone can point me to a good app for remotely managing the app. Thanks a lot.

Did you found a solution? I would like to do that also,

could you not just use vnc server?
Teamspeak also works.

computer + old person = tech support.
I don't have a good solution to your problem (and I doubt there is one that would allow you to do this without your father first starting up a program each time he needs your help, which might require it's own tech support solution). Can I suggest that you take the GT10 back (unless you already have one, keep if for yourself!) and get him an ipad?
Before you jump on me and call me names, I just want to point out that the ipad does everything your father wants (probably) with the added benefit that tech support is always: "hit the button." My mom was about to buy an android phone, but when I realized that she A) doesn't need it; B) won't use any of the advanced functions; and C) I'd probably be doing daily tech support only to find out that she still writes down all her phone numbers into a paper book. I told her to get an iphone, and I'm very happy with that decision. She still doesn't know how to use it, and could probably have just stuck with the motorola razr v9 for her purposes, but she likes that she's "modern" and the novelty of looking something up while she's out hasn't yet worn off.
Don't get me wrong; I think that android is a far more capable system. For me, I'd choose an android tab over an ipad any day. But for mom, it was an easy choice. Only 2 days of calls, and she figured out that the solution was always to "hit the button." Phew.

You can't remote control any android device. My company, not me, was attempting to create an app to allow them to perform remote tech support and setups for android devices but they ran into so many legal issues from all the developers and OEMs that create their flavor of Android. You can remote control computers but you can't remote control android.

[Q] Plausibility of hearing mic input + music through headphone output

I hope the title mostly explains my question: I would like to know devs opinions about how "do-able" it would be to create a sound driver/app that would allow a user to hear the microphone input mixed with other audio when earbuds or headphones are connected to the device. I'm guessing that this would not be difficult. I am an electrical engineer with programming experience (only written one android program via tutorial, though), and I am thinking about trying this. I thought I'd start by bouncing this idea off you experienced devs.
Need for app (further explanation): My girlfriend is partially deaf-- she wears hearing aids to help her hear the outside world. When she listens to music or makes phone calls with her phone, she likes to use her earbuds -- lots of us do -- and like lots of us, she can't hear the outside world with earbuds in her ears -- in her case, she can't hear the outside world at all. I was thinking that if the android device could just forward an audio stream from the mic input to the headphone output, controlled by an on-off/sensitivity option, this would not only become a very sophisticated hearing aid replacement to devices that the deaf community has to pay thousands of dollars for, but it would also be useful to all of us who need to better hear the outside world at times when listening to music or talking on the phone with our earbuds in.
Like I said, it seems like a simple app or sound driver extension that could work with any audio output stream. I would get into the android api and start working on this unless there were specific reasons why this is not plausible. So here I am, bouncing the idea off you experienced devs.
What do ya think? Top-level approach, how could this be done? Does android limit this type of functionality?

I'm not a professional dev.
But I heard android can't process the mic input at realtime.
I think this is similar case with noise canceling.
Noise canceling needs real time mic input processing but android's API doesn't support it.
I don't want to say this...but iOS is way forward than android about this area.
(It actually supports sound processing at almost real time.
If you want to find example, search for amplitube or imic for iOS.)

Thanks AndroidON for your reply. My girlfriend currently uses an iPhone, and already I have found http://scientificaesthetic.com/2010/09/22/reviewing-awareness-for-the-iphone/ which is exactly what I hoped to find/develop in the android platform. So while this is awesome for her, I may never get her on to android now!!! heh heh Seriously though thanks for sending me on the iphone search, because that's just what she needed.
(Boooooo Android!)
Can anybody else confirm or deny that this is not possible on the android platform? I don't need processing, just signal forwarding with attenuation ...which may mean processing if converting from A/D then convert from D/A again... I was hoping hardware would allow the signal to stay in analog, to avoid the need for realtime digital processing. This is somewhat technical and I hope to hear from developers, and I would like to begin developing it if it's possible, which is why I originally posted in the dev section.
bumping this thread
Thanks for considering my question!!
Anybody know if this is possible with the android api?
Interesting question and a good idea for an app!
Well, it is definitely possible with java but there would be some delay due to a minimum buffer.
Look here (sorry, can't post links): stackoverflow.com/questions/5379063/audiorecord-and-audiotrack-latency
They say that probably it is possible to work around this problem with some C code
Hmmmm.... interesting! Thanks for that!
Yeah a little bit of delay would not be a bad thing in this case. The iPhone equivalent of this idea is Awareness! and it has delays of 1 to 2 tenths of a second.
No problem!
Well, maybe delay is ok for this
Re-Bump
Hi,
Sorry for reviving an old thread, but I really am interested in an app like this.
Has anyone done anything about this ?
Thanks,

DEV Testing

Just wondering, but is there a need for dev testing? As in, a need for developers to have a small list of people with a given device that they can send a ROM to, to make sure it boots properly or is willing to run for a day intentionally looking for problems?
I have a Moto Droid, Incredible 2, and the fascinate. First two phones are collecting dust. Meant to be spares. I'm comfortable flashing, and I'm probably one of the few on this forum who regularly uses every smartphone feature extensively. Dozens of texts an hour, MMS, bluetooth (with keyboard), wifi, browsing constantly, usually with the music player running. So when something is broken in a ROM, I almost always find it within a couple hours.
So I'm curious. Is there a need for this in the community? I'm not a developer, but I'm definitely a power user and with these communities being the only reason I fiddle so much with my phone I want to give back. And I love being on the bleeding edge So I'm always available, with the listed phones above and if we find devs actually have a need for this it would be cool in my opinion to collect a list. So, devs if you have a need for testers I would love to hear from you. Also thank you all for the time and dedication you put in to make these phones worth so much more than if they were used as is off the shelf. I greatly appreciate it.

[Q] Firechat offline chatting without data

Any one using firchat, it claims chatting without internet and cellular network. but not working for me.
https://play.google.com/store/apps/details?id=com.opengarden.firechat
No one uses Firechat?
didn't get you
I'm talking about android version. But working similarly, but what is solution ? Did yours working ?
Its worked with wifi direct for me(just beetwen 2 phone)
I don't really have any use for this, but love the proof of concept and the innovation. Hopefully it'll take off and force carriers to lower the prices somewhat.
actually main concept of offline chat not working or not able to use how.
Firechat has come a long way as an app with encrypted private messaging and public forums. About 200ft range and message hopping store and forward to other phones in the mesh til it propogates. 5 million users in the app. Only 1 million Android downloads so the rest must be iOS. I would think early side load people would have gone play store but it could be that people in remote areas share the APK. I see lots of "kids"in third world countries posting.
Briar beta shows promise but it's complicated and requires logging in and out to halt it. Serval mesh is really complicated and a non techy person will just give up. There's another one too that uses transmitter dongles.
