I recently started trying to complete a phone call recorder for the Nexus One running FroYo, but I've been having trouble getting the audio source to work correctly.
Using MediaRecorder.setAudioSource with MediaRecorder.AudioSource.VOICE_CALL results in a 0 kb file.
MediaRecorder.AudioSource.VOICE_DOWNLINK and MediaRecorder.AudioSource.VOICE_UPLINK both only record from the MIC and are therefore no different than MediaRecorder.AudioSource.MIC
Does anyone have any experience working with this part of the API, trying to do something similar? My next step would be to re-work using AudioRecord, but from what I've been reading online no one has had any success with that either.
Any help would be GREATLY appreciated. Thanks in advance!!

Googlevoice can do this. I believe you hit the number 4 during a call to start recording and 4 again to stop.

Well damn, you got me there. Indeed that does work, although it requires someone to call you through your google voice #. I think there's still enough demand out there for a native call recorder that this is still worth investigating a fix.
But thanks for the info!!!!

No, actually in my state (Texas) it is not. As long as "1 of the parties is aware it is being recorded" (uhhh myself) it is legal.
The last time this was discussed Dianne Hackborn said that the G1 did not have the hardware for this to happen.
The problem was that the baseband processor did all the work and the raw audio stream was never exposed to Android (yep, including if you use a bluetooth headset, all done by the baseband processor) she said the problem was that qualcomm et al tended to lock up the functionality making such things really hard to do without their co-operation at driver writing time.
I'd guess this still holds for the N1.
Google voice however is just fancy VOIP so that is all done within the kernel hence the audio is easy to get at.

finally i have a right to do something in texas besides own a gun
man, i really wish there was an app for this (besides google voice) =/
I have been trying to find an app that takes this one step further, and can be used as a voicemail service.
Here in Australia we have to pay for the call diversion to carrier provided voicemail, then pay to retrieve the message.
If the phone answered the call and recorded the message it would eliminate the need for carrier voicemail.
Recording calls will be great if you can make it work, but reading other posts it seems it may not be possible.

Points well made, remember though an app to be issued on this site, might be unlawful since the servers are located in the USA.
As too anyone interested in the state laws for recording a conversation per state:
http://www.rcfp.org/taping/quick.html
Remember one thing also, the reason Google removed all the recording apps off the market is because they didn't want to be responsible for the actions.
Google voice records a conversation after it notifies the caller on the other end of the call.
Just an fyi too you all.

Very interesting, and that would certainly explain the limitations of the API on the Nexus One. I really wish there was some way around this.

Could you provide a link to back that assertion up? as I said I don't believe there have been any actual call-recording apps on the market, due to technical limitations, just normal recording apps that could be used to (poorly) record a call. And I don't believe any of those have been pulled.
Personally IMHO the notion that you can't record something you hear is nonsense. Thankfully I don't live in a country where this is so.
If you have a SIP account (or VOIP), you can download the app 3cxPhone from Android Market and in the Settings there is an option to record all calls.
I have tested it and it works perfectly. Both parties are recorded loud and clear unlike most of the old call recorders on the Market where you could barely hear the other party. I think it has something to do with SIP apps, like Sipdroid and 3cxPhone, calls function as Media files rather than phone calls on Android, allowing the recording of both sides of the call equally.
Anyway, the recorded call auto saves as a .wav file on your sd card under /3cxPhone/recordings.
Use your Google Voice number as a SIP account. Substitute 3cxPhone for Sipdroid in the tutorial... http://androidforums.com/android-lo...-your-android-phone-free-us-canada-calls.html
There's also trick you can do to record all in and out calls with 2 Google Voice accounts, one of the GV callback apps in Market, a MagicJack, and your regular phone calling plan (not Sipdroid or 3cxPhone).
Long tutorial short...
-you set up your MagicJack number as a forwarding number on GV line 1.
-Then, after its registered, go into the MJ login page and auto-forward all calls to your GV line 2 number. You can put your MJ in a drawer and never plug it in again after that.
-in the Android GV callback app, login with GV line 1. In the Settings, change the "This Phone's number" to the MagicJack number. Make sure your GV line 1 does not forward to your cell phone. Check desktop GV Settings to be sure.
-in GV line 2's Desktop version, make a new Contact with GV line 1's number. Name it whatever you want. In the Settings for that Contact, make all calls ring your Mobile number. Turn off all Call Screening or Call Presentation for that Contact, meaning calls just go through without options to reject or send to VM.
-Finally, to make calls, in the GV callback Android app, enter a number or choose a contact to call. It will call you back on your MJ number, which happens to forward to your GV Line 2 number....which is getting an incoming call(calling your cell), which means you can just push the number 4 as soon as you pick up the callback to start recording.
Your outgoing Caller ID will be GV Line 1 but your recordings will show up in GV Line 2.
The end

While i do appreciate these "workarounds", that was not the point of my thread. From what I can tell, there is a large demand out there for a native application that doesn't require using a VOIP service such as Google Voice or any wonky "setups", and records calls directly to the device. None of the apps I have found so far will record both the incoming and outgoing voice stream, and from my testing with the API and what I've read online, it doesn't seem possible to do with the Nexus One.
I'm more or less just looking for input from people who are familiar with this API and have attempted to do something similar. Thanks anyway....

I beg to differ. All the files saved are ending up as 0 kb files and of course won't play. Exact same problem I had during testing of my application. My guess is he's using the VOICE_CALL audio source which was leading to that same problem for me.
If it really does work for you, what location do you have set to save the calls and what format are you saving as?

Total recall uses microphone too, so did you read the first post ?
WOT this is not any kind of production/everyday app. Lets pursue other options or future releases of this.....
Hi All
Sorry if this has been covered elsewhere or fixed, I couldn't find anything that covered this exact problem hence the post.
Also apologies in advance, this is gonna be a little long...
A little History:
====
I use my cell phone for both work and personal since I own my own business. I really hated having clients or potential clients knowing my direct cell phone number when calling them.
While I could program all of them into my cell with a *82 in front to block the caller id, I decided to go the other way so I wouldn't have to remember to do it on manually dialed calls.
Thus at my request, AT&T several years ago changed my network ANI default setting from "Allowed" to "Blocked" meaning by default, my caller id info is blocked when I dial, unless I put *82 in front of the number to override.
People in my phone book that I wanted my number unblocked for, I simply put *82 in front of their stored number.
At the time I did this I had a Blackberry Curve and all worked fine. I could call _AND_ SMS/TXT/MMS as normal - important to note.
Recently I got an Atrix 4g running Android 2.2 (now rooted). All was good until I tried SMS'ing a number in my phone book. Turns out the SMS app (default android app) does not like the *82 in front of the number. Instead of recognizing *82 as a valid ANI control code and thus ignoring/passing it, it thinks it is part of the actual phone number and errors out.
So now I have to have two numbers entered into every entry in my phone book that I want to be able to SMS or call without my number being blocked by default. One entry with *82 in front of it to call them unblocked and one entry without the *82 to be able to SMS them.
Anyone have any ideas how to get around this? As I see it it's something that either Motorola or the Android developers need to fix, i.e. telling the SMS app to ignore/pass valid ANI control codes.
Thanks in advance

Is is truly unbelievable to me that in this day and age such an essential phone function could have been overlooked! I have been searching for days and days and found NOTHING or got stupid responses such as "use Google" (Online only, uses Data and for US Citizens only) or "use voicemail" (expensive cellular provider subscription add-on)... I mean, come on! When even the cheapest home phones can be gotten with built in answering machines, how come this essential feature is nowhere to be seen on android phones?
What's the deal, what's the technical hangup, what's the problem? Can anyone explain the REASON why there are NO call answering machine-like apps of any kind out there?

Im looking for the same thing and can't find it too!
Here is my need. I have a business phone number and my personal cell phone number. All my customers should call me to my business number which I can set to auto-forward to my cell only at the time I want to. But some of my customers know my cell phone number and they keep having this bad habit of calling me on it instead of my business phone number.
I'm looking for a app that will be tracking in the background the caller id number of incoming calls, if the number is a on list of unwanted that I have set, it will auto-answer, play an audio file recorded by me (like: "Please dial 111-222-3333 to reach me, thanks you") and then hang-up.
I don't feel alone with the need of a solution like this. And there are apps that can auto-answer call according to the caller id and there are apps that can play audio in a call, I don't see why it could not be technically possible to combine both.
wow
can't belive it, i was looking for the same and found several threads like this one, that's sad
let's hope sth comes up
Yeah, I used to have this function on my old fliphone from way back in 2002! Also, on my Windows Mobile phones after that...
Exactly. My nokia flip from ages ago (ran symbian OS) has an app on it called "Advanced Answering Machine" or "Advanced Call Manager" or something similar.
I could set it up so that it would direct calls to different greetings depending on the caller ID. An example of this is, I wont accept calls from "unknown" or "blocked" etc numbers. ACM/AAM would handle this perfectly. It would answer the phone, play the Telstra (thats a telco in australia) message "the number you have called is not available from this service." twice, then hang up. Later on I found out I was missing some important calls (the message confused some people such as the landlord who had a blocked number) so I changed it to "I do not accept calls from blocked numbers. To unblock your number, dial 1831 in front of your number. It wont cost you any more". This fixed the problem.
It was also programmed to answer calls after 30 seconds of ringing and play a standard greeting then take a message.
It was a very versatile program. I could (for example) divert certain calls to a party line if I didnt want calls from that particular number; however I didnt, as the diverted leg would cost me a fortune.
Its a shame on these advanced handsets today that such a simple, commonly available on landline phones, feature is not available. I can control televisions, fly remote controlled toys and vapourize components with a big bank of capacitors over bluetooth using my phone, yet it cant perform a simple answering machine function.
From what I hear the API that handles these functions is not directly accessable to developers; probably because "malware" could hook in and dial high priced premium calls and rack up huge bills all the while the phone owner not knowing until the monthly account comes in.
I did see one answerphone somewhere but it utilised the speaker so if it took a call (for example while your at the pub) the caller would not hear your greeting, or on the train everyone around you would hear your greeting and then the callers message, so not very practical. It would NOT work properly while the phone was on mute.
xperia phones come with buit-in answering machine feature. or use jail broken iphone and u have half a dozen apps which can do it.
unfortunately in android noway.. even if u r rooted.. no way
Before i had a droid 3, it wasnt possible to record incoming and outgoing calls. I am owning a Photon Q 4g LTE now, and i was wondering if it works with this device or not?
I have Google Voice, which allows me to record incoming calls.
If you want to record any calls, I'd guess you'd need some sort of an app. There are a few... have you tried any of them?
This one I saw on the front page of xda-devs not too long ago.
There's a bunch on the Play Store as well.
There is also a module for Xposed Framework that allows you to record calls.

Indeed, there are a lot of recorders like that, mut some phones like the droid 3 dont support it. The S3 does support.
I have a Photon Q 4G now, and i was wondering if this phone supports it or not.. If you guyz have this phone, i would appreciate if you could install that app called "" in call recorder "" than go to settings of that app -call recorder settings-Audio Source, and select PHONE LINE.
now make phone call, if it works than i know enough..

Well I have this application, and when I have audio source set to PhoneLine only first couple of seconds is recorded correctly, then recorded voice becomes all squeaky and hardly understandable, but no impact on call quiality. When set to Microphone the other party does not hear me at all. I got a response from the author about my issue, he suggested to use Microphone and higher Gain Level, but I haven't tried it yet.When I do I'll post my results.
Unfortunately no help...
Might be a little non-trivial to set up however using Google-Voice adds the functionality to record calls to this phone..
It is a little tricky to get it working correctly with Sprint in general but well worth it! You can record, then access everything online including texting and calling (using your phones number and plan) from the web..
I know some people may not like using google for things like that but it just works so good...
