Notification of wired headset removal

Is there a way to detect when a wired headset has been removed? I'd like to write a program to stop audio playback if the headphones are unplugged, since it's pretty embarrassing to have the music blaring out of the speaker.
I figured this should be possible since the phone itself can detect the presence of a headset to know whether to auto-pickup a call. (This is for the apache, though i imagine the function call would be the same for other devices as well.) Thanks.

any ideas?

That's cool to have, but on the HTC Magician, the earpiece is just a normal 2.5mm with mic, plus a answer button, plugging it in doesn't have any visible notification on the phone.
It might work for yours, but I'm not sure about all other devices.

On WM5 just use the state and notification broker. State is saved in the registry.
For WM2003 you have to go at a much lower level I think.

If someone is writing an apps, please include for wireless bluetooth stereo headset when lose bluetooth connections.

I think this would be a really useful program, especially for Universal owners as sometimes when we disconnect the wired headset, the phone still thinks that it is plugged in and thus we cannot hear any notifications.

Hmm - that's what I thought too, but it looks like (at least on the Apache) that there is no such state. One of the other threads referenced a state named "Headset", but I can't seem to find it.
Nonetheless, the phone must know whether the headset is plugged in, because it prevents you from turning on the speakerphone if the heaset is in.

Any ideas?

you are right!... i will do some work on this and see what happens

How does MyTouch 4G deal with headphones with no mic and how to favour bluetooth?

Hi,
I've been using the Car Dock Home v3 app launched from HTC's car dock when I'm driving. Yesterday I was also listening to some podcasts form the phone by connecting the headphone jack to my car's aux input. I had a bluetooth headset connected.
Then someone decided to call me and it was disastrous. The car mode causes the phone to read the incoming phone number and let you answer or decline by voice, which is neat, but instead of going through the car's speaker (headphone out) it goes through the built in speaker. I don't know why it would do this, but with the car noise it was impossible to hear it.
Then after answering the call, instead of going through the bluetooth headset, I heard the caller through the car's speakers (sounded great) but they couldn't hear me at all. I can switch to the bluetooth headset manually, but it's too dangerous to try and navigate the tiny buttons and text while driving. With another caller they could hear me, though.
So I can't figure out what the phone is doing when you have something plugged into the headphone jack but no wired mic. It seems like the phone's microphone is active, but not in speakerphone mode, so it's probably too quiet on the other end to clearly hear me unless I talk right into the mic, which I can't do while driving.
So questions:
1. Is there any way to increase the internal mic gain to use the phone connected to the car speakers as a true speakerphone (and can this be done without creating echo/feedback)?
2. Is there any way to have the phone automatically prioritize a connected bluetooth device over the headphone jack?
3. If the answers to 1. and 2. are no, is there any way to have a car mode specific dialer screen with nice big buttons for selecting audio source manually?
4. Can I get the car mode to read incoming call info into the headphone jack rather than the internal speaker?
Thanks!

Key action you must take when your phone rings...
DON'T touch the screen. Click your BT device to answer.

Are you sure that works? I didn't try that, but I used my bluetooth headset to launch genius and dial a contact by voice. Everything worked through the bluetooth headset, but once the call connected, it switched to the car's speakers.

I'm pretty sure that the car mode initiates hands-free mode, which automatically turns on the phones internal speaker when a call comes in. See if there's a setting that prevents hands-free from turning on in the app. That might fix things the way you use them.

While the phone is ringing, activate the connection via BT. It works for me now, and it worked on the stock ROM. But you don't ned to take my word for it, just try it.

I'll give that I try when I get a chance. There is an option to automatically enable speakerphone in the car dock app, so maybe disabling that will also fix the problem. However, so long as the headphone jack isn't in use, it works exactly like I want it to:
If the bluetooth headset is connected, it gets used for answering and making calls. If the bluetooth headset is not connected, when answering or making calls the phone's spakerphone is automatically enabled.
The issue is that with the headphone jack in use, it seems to take precedence over both internal speakerphone and bluetooth headset.
My guess is that if the headphone jack is in use the phone assumes that you're using a wired headphone/headset with its own mic. If that were the case, the behaviour actually makes sense: if you've got a wired headset in your ears, that's where you'd want the audio to go. I suppose if there is no external mic but you're wearing headphones, using the internal mic without speakerphone gain also may make sense: you'd hear through the headphones and hold the mic near your mouth to talk. The problem is it ignores the case of external speakers versus headphones. Especially in car mode it should be smarter about how it deals with these options. Of course, some of the issue may be due to the third party dock app, so maybe I'll have to try with that disabled or contact the developer to see if he can do anything.
It's little usability issues like this that make me want to drop Android, although I have no idea if there's actually anything that really works better.

Training yourself to touch the earpiece instead of the phone to answer is not overly difficult. It only took me one or two "oops" experiences to stop touching the phone.

I use the phone and aux input all the time while driving, but the difference is that I don't have a bluetooth headset involved.
Audio comes out of the headphone jack and I speak into the phone's mic and it works fine. Turn the phone volume to max and use the headunit volume to adjust.

So I have had a chance to test it. It's true, if you use the bluetooth headset's button to answer a call it does get properly routed to the headset. If you answer by taping answer on the screen it gets routed the headphone/speaker + internal mic.
It does also seem like the internal mic is used correctly and pretty much sounds as good as the speaker phone mode, so answering a call while wearing headphones or using speakers doesn't seem like it should be a problem (assuming echo isn't an issue with speakers). Don't know why that one caller couldn't hear me, but that could be some other reason.
What doesn't work, though, is initiating a call from the bluetooth headset if the headphone jack is in use. Using the bluetooth headset button to initiate genius voice dialing works as expected until the call is connected, at which pint it then gets routed to the headphone/mic instead of the bluetooth headset. There doesn't seem to be any way around this. Of course, since you are initiating the call, it's probably not too bad to just unplug the headphone jack first...

Epic: AUX in car - won't pick up Bluetooth calls

I was hoping this problem would be resolved in Froyo, and as of EC05 it remains. When I'm plugged into the AUX connection in my car and receive a phone call, the car's Bluetooth handsfree picks up the call and audio does stop playing, but the phone call audio doesn't switch to Bluetooth. I have to unplug AUX, at which point Bluetooth picks up the audio.
Anybody know of any fixes for this issue?

From what I understand, there is no software fix for this. The 1/8'" audio out is hardwired to route calls to the headphone jack whenever anything is plugged into it (because they assume you will be using headphones with a integrated mic).
Your best bet is the OEM Samsung Epic Car Dock-
http://www.thecellguru.com/Products/26862
It is by far my #1 Epic accessory. It routes the audio through the usb jack into the dock, and from there to your car stereo. Bluetooth calls are not affected. It is the only working solution that I'm aware of.

@mattallica76 - Thanks for the info! That works for me, no problem.
Oh, and, also thanks for linking me to the cheapest outlet.

[Q] Bluetooth Headset for Phone, and Audio Jack for Music

Hi all,
Basically, I'm trying to figure out if the subject is possible.
What is happening now is that if I have a standard stereo audio cable plugged in (non-mic) with BT connected to a headset and I receive a call, the audio for the call goes through the headset jack instead of the BT, and because of that there is no mic to pick up my voice. This leaves me able to hear the caller, but them not able to hear me.
Any thoughts?
Thanks,
Ben

Had sort of the same thing happen to me, except I tried making a BT call while plugged into headphone jack and other end was plugged into my car's aux port. Started to make the call and quit. Guess its another limitation of the current set of roms, if I'm reading correctly.
My question is under android I would have a microphone on the keyboard so that if I was going to navigate somewhere I could just hit that and say where I wanted to go instead of typing out a long address. I am using HTC Locations, and don't see any provision for allowing me to speak my destination point.

I don't think that's possible yet, but there is a lot in the way of BT profile and audio settings that may help that. we'd probably want to look for something that doesn't auto cut off when a jack is inserted
as it stands, BT is buggered (music playback) on ultrafruit ROMs anyway so we're not missing much, xbmods ROM worked fine but his left for pastures new and everyone else is being silent on the matter.

Why aren't bluetooth microphones supported?

I just assumed that I could use any bluetooth microphone for voip, voice recording etc. I currently do not have any bluetooth device but I tried 3 at a friends and they all paired for sound, but failed to work in using a voice recording app or a voip app. In a voip app the sound went strange (long sounds on the dial tone buttons) and then the sound resumed coming out of the tablet even though the headset device was showing as connected. Only a reboot solved this.
So I assume the bluetooth stack doesn't support recording, but why not? Isn't this a basic thing at this point? If I connect a bluetooth headset with mic that should be my input and output on sound for the time it is connected.
Or has anyone had success with a certain bluetooth model for recording?

No one can provide info on this? Is this the norm for tablets? I would assume even some ancient gingerbread phone would work with bluetooth headset/mic.
Does cyanogen team ever modify the kernel to include more functionality such as this?

I'd check other bluetooth threads around this section, but I've heard several people who've used bluetooth headsets with Nexus tablets. It may be a setting issue (particularly the device setting under bluetooth and the app settings concerning headsets).

Same here, Plantronics bluetooth headset works perfectly for voip calls using Talkatone.

Thanks for the info. I don't have the model names off-hand but I'll ask my friend what they were. I wasn't aware that once a bluetooth device was paried that there were any additional options. I was under the impression that it was simply pair and use. With the case of a headset/mic I assumed it was inherited as your sound output/input for all apps while paired. The voip I tried is csipsimple and a voice recording app. I'm glad to at least some models work but I hope it isn't hit and miss and you have to be selective of what bluetooth device you use but rather something I was doing.
I didn't expect there to be any settings as well because even with no bluetooth recording device paired, I don't see anywhere in the settings recording recording (like mic volume).

Can't get mine to work. Single ear set I don't even get sound. Just dead air all around. The Southwing SA505 stereo gets sound fine but no mic function and on Groove ip no sound or mic on single ear or stereo. I even checked the settings making sure bluetooth was selected.

I'm from Canada so I can't try talkatone as I can't get google voice. I now purchased a btheadset. It pairs fine and I hear audio in all apps but I haven't found one app yet that works with the bluetooth mic. I wanted a voip sip app. I've pretty much tried all the free ones and other users have posted comments of bluetooth issues as well. There are a couple of paid sip apps that claim to support bluetooth, but I don't want to buy them to only find they don't.
So yes, android supports bluetooth mics, my thread title is inaccurate, but it seems the vast majority of recording apps do not have proper bluetooth support. Can someone name any app besides talkatone, even a voice recorder that works with bluetooth so I can just test it?
I'm actually surprised it's this bad. Bluetooth audio isn't that cutting edge. It should pair and now act as your soundcard so to speak. I initially thought to blame the OS because I thought any app that requests to play a sound or record a sound, would be re-directed by the OS to now use the bluetooth device.
I'm pretty sure it works exactly like this on windows. Or for example, I have a usb headset on my pc. It shows up as a soundcard. I make it the default and every app now uses that. No developer had to code to use a usb headset/mic, it just works.
Again a little disappointed that it's been a little trying just to get a bluetooth headset to function properly. I tried 3 at my friends that all pair fine and work flawlessly on his playbook in all his apps, and now I bought 1 so it's hard to say all of these bluetooth headsets have quirks and don't work properly with android.

Still trying to get this working. It pairs fine, and shows in the bluetooth details as being connected with phone audio and media audio.
It's a Aluratek ABH01F which I've read great things about. It supports a2dp. I'm not too familiar with bluetooth and microphones so I'm not sure if there is anything else to check for android to support a bluetooth microphone.
I don't know why I didn't think of it before but I tried google's voice search and it doesn't work either. I can hear the audio fine, just no mic.
Can anyone confirm if google's voice search works with their bluetooth mic? You probably have to walk out of the room to verify it's not the units mic that is picking it up obviously.

I'm not convinced bluethooth mics work at all on the nexus 7. I could chalk it up to my headset just doesn't place nice with the nexus 7 but again I tried 3 bluetooth devices at my friends. I found this post on another site:
Well, I got around to testing a bluetooth headset. single earpiece, Avantalk AH28. Not the best, but it works fine with a phone. Paired with the tablet fine. I dialed on groove ip - dial tones came from the tablet, the ringing transferred to the earpiece, when phone was answered there was no sound transmission at all- not from the bluetooth earpiece, or from the tablet. Just dead air. Tried it twice.
2nd test- google music played from tablet- not into the earpiece.
I have a stereo bluetooth headset with mic that I can test with but will have to charge that one up first. Will get back to you.
************************************************** ****
Got to my stereo Southwing SA505 bluetooth test. It worked to play music from tablet beautifully. Did not work with groove IP- went in and made sure settings were set for bluetooth- Mic did not work.

Again, I hear audio fine via bluetooth, so I wonder if some of you were thinking the bluetooth mic was working but it was actually the unit's mic.
This app called tapemachine specifically states it has bluetooth support. It fails for me when I change it to bluetooth in the settings, can someone else try it?
https://play.google.com/store/apps/details?id=com.samalyse.free.tapemachine&feature=nav_result#?t=W251bGwsMSwxLDMsImNvbS5zYW1hbHlzZS5mcmVlLnRhcGVtYWNoaW5lIl0.
So I'm starting to think my thread title is correct. If I am, I'm hoping there is a way to hack some file changing the available audio profiles. I've read others doing something similar with different devices when the manufacturer disable those audio profiles. I would find it doubtful that google/asus would do this though.
Anyway, if anyone can try that app, or confirm that say grooveip is using the bluetooth mic and not the device. An easy test is tap on the unit mic while recording and see if you or the person you are talking to hears that.

No one? I know a couple of you said it worked, but are you sure grooveip is actually recording via the mic? I can hear phone calls using various sip apps with bluetooth, but I know the mic isn't recording. One of the headsets my friend has is a Motorola MOTOROKR S9 Stereo Bluetooth Headphones. Link here: http://www.amazon.com/Motorola-S9-Bluetooth-Headphones-Packaging/dp/B0017KTOJK.
I've only tried stereo headsets, so maybe that is the issue. The Motorola HS850 is a single ear piece, I'm not sure what plantronics set you have.
I'd really appreciate if someone else can verify if bluetooth is working. If bluetooth recording in fact works with the nexus 7, I must be really unlucky with 4 headsets that don't, which I find highly unlikely or nexus 7 has poor bluetooth support. The only thing left is my bluetooth hardware is broken which I find even more unlikely. Aradreamer, you say you've seen several posts saying bluetooth works, but I haven't found one post explicitly stating bluetooth recording works. I found more post on other forums clearly stating it doesn't work.

odd odd ...
first off i have the Nexus 7 16g with it rooted.
heres what i did first i bought the samsung HM1200 didnt thoroughly test that 1 because i figured it just wouldnt work with the device ( or was broken ) once i started to get all this screeching out of it... i heard sound momentarily then all it did was the screeching at different levels. returned it yesterday. then i added a couple more bucks ( about $27 total ) and got the plantronics M20 took it home and crossed my fingers. got it all it paired up and what not and ended up with the same condition except now the mic is working perfectly. i tested this thoroughly now over and over inside and outside and also away from the N7 to be sure the mic is working. this is great BUT i cannot hear any sound at all coming in to the N7 except the same screeching at constantly varying levels. this is with both grooveip and talkatone. i also tried uninstalling beats audio and rebooting but i read somewhere this wont change the drivers back to the originals and i still have the same condition. i just got the N7 about 3 weeks ago and the store where i bought it has a price guarantee so i am today planning to return it and get the N7 again but this time the 32g version. ( they got 2 left so i will be going ASAP. ) so almost all the work i put into setting this thing up is about to be wasted. still i am going to do it anyways. to me its just the point of getting the best i can with my available budget/resources and i can easily see this thing be full and kicking myself in the butt for not doing it. this time around i will test all of what i mentioned here BEFORE i root it. in fact i will only install the necessary apps ( grooveip/talkatone etc.. ) during testing. its a real pain in the butt but it is a MUST i have this thing working as a phone with BT asap. thanks for the input and i will report back later.
update: actually in a more quiet room i was able to hear myself on the BT headset but very very low and in the background behind the screeching. still will report back later with the new unit.

For some reason the Bluetooth headset profile on the n7 is totally broken. I tried MANY headsets and none of them work. It is either the drivers, the hardware or the kernel. I hope it fixable in the 3g version.
Sent from my Nexus 7 using xda premium

yep i am sitting here now with the 32g N7 and the first thing i did was try the BT unrooted and its the exact same thing screeching like mad can hear myself on the mic perfect from the other phone and can hear the other phone low in the background of the screeching on the N7 ugh
i have a temporary solution that should work till its sorted.... i need a new headset for my computer anyways so ill just make sure to grab one that is USB then when my OTG cable arrives i am pretty sure that should work. it will be corded but at least i can use the phone somewhat normally for free. ill let you know. now im off to rebuild the whole thing back to where i had it in the 16.

Bummer. Hopefully they fix it with 4.2 or with the 3G version.
It also seems that if you try to toggle speakerphone / BT headset in various voip apps the tablet will crash and restart.
I tried with GrooveIP, Talkatone and the build in phone app (After changing the framework-res.apk file).
I also noticed i had better luck getting the BT headset to fully (and randomly) work when doing outgoing calls. It never worked on incoming calls.

Any progress on this?
I've noticed the same problem and just returned a BT headset due to the problems in GrooveIP & Talkatone
As a side note I was able to get the BT headset to work as a MIC with the google voice commands by using the following..
- Soundabout
- Under BT settings set it to force mono BT mic
- Set audio to wired headset
Just as ref, I'm using my N7 in my car, so my setup may be a bit different.
But this worked, I was able to tell my N7 commands and it would read out the response over my car speakers.
Anyone had success with a USB mic? Curious if that will work.

I'm very interested in this thread too.
I have a 32GB nexus 7, rooted and unlocked. I have a Platronics M100 bluetooth earpiece. My goal is to be able to dictate to Evernote through the BT earpiece. It is pairing and under the connect settings it is showing up as "phone audio". But when I speak into it nothing is happening in Evernote. I also do not get media audio through the earpiece.

My Sony xperia Z accepts audio from bluetooth microphones, but only during a phone call.
When the call is terminated the paired bluetooth mic becomes inactive and the phones built in microphone takes over. I have tried many apps but none will accept audio from a BT mic.
I have tried a number of headsets and speakerphones and they all behave in the same way. Sound is not a problem as the BT speaker simply replaces the phones internal one when paired.
The xperia Z has a setting which claims to: " record audio through bluetooth headset if available", but this setting does nothing. I keep retrying the setting at every android update, to no avail. Currently at 4.2.2.
When I plug in a wired headset, the speaker and mic simply replace the ones in the phone. Why doesn't bluetooth behave in the same way?
This issue has been raised in many forums, in relation to many android devices, but never answered.
