Android :: KeyCharacter Map Generation And Bluetooth Headset
Oct 11, 2010
I am facing a problem with Bluetooth Headset and KeyCharacter Mapping. When I press play/pause button from Samsung sbh-, its not getting reflected in Phone. I traced and came to know that, normally scan code of 164, keycode of 85 is formed when i press Headset play/pause. And PhoneWindow manager will intercept this and send ACTION_MEDIA_BUTTON if keycode =85 (KeyEvent.KEYCODE_MEDIA_PLAY_PAUSE). But keycode that I'm getting is 0 even when i press headset play/pause in PhoneWindow Manager. Even in KeyInputQueue, the keycode that is obtained is 0. Does anybody when keycode gets generated?

I am a new SE user and am still getting to grips with using the phone's features. Could anyone advise how to transfer a call from a headset back to the phone and phone to headset? Whilst I am asking inane questions, is it possible to use the phone i.e. return to menu when in a call?

I write a sample code to discovery a Bluetooth headset(jabra BT2035). referece http://developer.android.com/guide/topics/wireless/bluetooth.html#DiscoveringDevices
But it can only discovery my notebook computer. If my notebook computer enables Bluetooth and sets Enabling discoverability.
The SDK document snippet:
android.bluetooth.device.action.FOUND"
public static final String ACTION_FOUND
Since: API Level 5
Broadcast Action: Remote device discovered.
Sent when a remote device is found during discovery. I think the remote device means a remote notebook computer except a Bluetooth headset. Could someone please help with this?

I have a Motorola bluetooth headset and with my old Storm I could push the button on the headset and it would say "Say a command" from here I could say "Call John Doe mobile" and it would call him up. Haven't figured out how to make this work on the Droid in the same manner natively. Is it possible or is there an application. Purpose of bluetooth is to be hands free. Its not very hands free if I have to pull my phone out my pocket to dial the number first to be able to use the headset.

I met a problem of bluetooth headset. I want to switch audio playing to bluetooth headset when bluetooth headset is paired. I found BluetoothDevice in android sources which can control bluetooth. However it is not contained in android.jar. So I used AudioManager.setBluetoothScoOn(true)
But it still can't work.

Can we play the audio(amr file) to the Bluetooth headset(no A2DP support) by using android 2.1/2.2 version APIs? If so can you suggest me which API I have to use to do the same?

I am writing an android app for storing and managing voice memos with some basic metadata and tagging.
When recording sound I use:
CODE:...................
This works well when using the phone in a normal fashion. However, it does not detect the presence of a bluetooth headset and still uses the phone's own microphone even when the headset is plugged in.
I also tried using MediaRecorder.AudioSource.DEFAULT, hoping it would automatically choose the correct source, but then no sound was recorded at all.
How can I a) detect if a bluetooth headset is plugged in and/or b) use a bluetooth headset as audio source for the media recorder?

On my phone, a dev phone, the bluetooth headset service is always running even though bluetooth connectivity is disable in the Settings app. Is this normal?
The ear speaker is not emitting any sound for maybe two weeks now, even if the on-call sound level is at max (5), so I'm checking a few things before I try to send back the phone for repair or exchange.

I'm new to Bluetooth programming and I was wondering if I had a Bluetooth headset that was paired to an Android phone. What's the best way to detect that a button was pressed? Are there modifiers to tell which kind of button it was (e.g. volume up/down, main button) or what kind of press it was(regular, long press etc).

Basically my Samsung Galaxy S2 gives me unlimited calls to mobiles/landlines and I want to make A LOT of calls throughout the day. I have a plantronics pro uc bluetooth headset which syncs up with my phone. I can send SMS and remote access the phone (too slow and clunky to make calls fast and simply).
What I want to be able to do is dial a number from my computer and my phone start call it. Essentially just want the phone on my computer. Paste a number in/dial it etc... click a link and the app/whatever call it.
(P.s. a remote desktop is not the solution as it is too slow - I tried that with MyMobiler. I have a skype number and can pay a small fee for unlimited landline calls but would have to pay for mobiles so this isnt a solution either).

In my understand, Anroid app supports only SPP connection not HFP and A2DP. However, I want to initiate HFP and A2DP connection in Android app just like selecting Bluetooth device in Bluetooth Settings menu. I'm not sure it is possible to use a intent including BluetothDevice object, so the intent receiver can initiate HFP and A2DP connection. If you have a idea, could you let me know that?

Using Android 2.0 SDK. Is it possible to direct the TTS engine's output to a connected BT headset? I've tried with KEY_PARAM_STREAM set to all of the available stream types but the speech is still output by the speaker on the phone.

I didn't find an API to detect if a Bluetooth A2DP is connected. Can somebody point me out how to check? It looks like if I route audio to Bluetooth A2DP without check, the sound will be routed anyway, and the speaker is turned off.

if it was possible to route audio files from the phone to a bluetooth headset on versions of Android API Level 7 and under (so versions older than the new Froyo) If so, do you know of any sample code I could look at to figure out how to do this? Or perhaps just point me in the right direction?

I see another post on this but it's a little outdated so I'm hoping there has been a recent development.Looking for a way to transmit audio from media (music, movies, audiobooks...not phone calls) to my standard bluetooth wireless device, which is not A2DP.This worked perfectly with no tweaks on my enV Touch so clearly it isn't a hardware issue, which by extension means there should be a software workaround, possibly in the form of a downloadable App.Anything that would work is cool though registry edits, whatever, I just desperately want to listen to audiobooks at work without buying a new headset!

Is it possible to record an audio (not a phone call) using the bluetooth input and not the device microphone? I am able to playback whatever am saying through device's mic but am not able to figure out how to use the bluetooth mic instead.

I am looking for a way to initiate the audio connection between the Android phone and my headset within my application. The idea is to simplify the connection process in such a way that the user doesn't have to go through the different settings menus anymore (Apps -> Settings -> Wireless & Networs -> Bluetooth settings).
Both devices are supposed to be already paired and the Bluetooth address of the headset to be known.
As far as I learned, the Bluetooth capabilities (available since version 2.0 of the Android SDK) are restricted to Bluetooth discovery and the connection of RFComm channels (host/client) between the Android phone and a Bluetooth device. Is there another way to request Bluetooth profiles on the Android system to initiate a connection to a known device from an app or is this impossible?

Since two weeks, I am the happy owner of a HTC Desire. Great phone and I love Android! One issue though...
The microphone volume of my Bluetooth headset is on the low side. It's the same headset I used with my previous Windows Mobile phone and in that configuration I had no problems. I paired a different Bluetooth headset with the Desire, but no luck... the volume is still to low. The volume of the build-in mic is ok.
Does anybody know what I can do to increase the mic volume? Settings? App?

is there any app that allows you to "turn" a wired headset to a bluetooth one via android?
You might think to connect an android smartphone to a normal wired headset (such as those supplied with most phones) and to exploit its bluetooth connection to use it on pc/consoles/... Do you think that it is possible?

I've been having issues with bluetooth headset dropout during a call. Pairing is never an issue, and the bluetooth connection is solid outside of a call, but during a call the bluetooth may drop out without warning. This means that while I'm talking to someone, there is no audible noise or visual cue that the connection has dropped and has defaulted back to the phone, and thus I'm relegated to a "hello? hello?" query before I check the handset and find out the caller was asking the same thing to my pocket (which also shows the devices are never more than, say 1.5m apart maximum when this happens).
As far as the phone is concerned, it's still 'connected' to bluetooth, as indicated in the dialer, and somehow isn't aware the connection has been dropped (or is and isn't showing). I thus need to redirect the audio via the UI either to the handset or speakerphone (away from the bluetooth connection it still think it's on), wait for the reroute to register, then redirect once again to the bluetooth to reestablish the connection. Again, without any audio cues the caller magically appears again on the headset, and we play the whole dropout game all over again. Connection duration seems arbitrary, lasting anywhere from 10s to a tens of minutes (with a 2-3 minutes on average).
This isn't isolated to any particular hardware, as I have had this occur on every one of my phones (Nexus S @ Android 3.x, stock and custom; Meizu MX @ Android 3.x - 4.x AOSP, OEM stock, and custom; HTC One @ Android 4.2.x - 4.3, stock only) and across all the headsets I've tried (Plantronics Discovery 925, LG HBM-585, Motorola H790), with Android being the common denominator. Note, I have used a Plantronics Discovery 655 and the same Plantronics Discovery 925 headset on my Nokia 8800 in the yesteryears, and have NEVER had connection or dropout issues.

I call internationally on calling cards A LOT (gv to those countries is 2x more expensive). Because of the calling card, sound quality and volume already takes a hit. Translation from a non-native language is more difficult over the phone, and damned near impossible for me if I can't hear them CLEARLY and LOUDLY. Same goes for the party at the other end if my microphone is sub-par.
Can anyone recommend a Bluetooth headset that works well with the droid and has AMAZING call clarity, quality, and good volume? Aesthetics are unimportant, I don't care what it looks like or how big it is. It just need to sound loud, clear, and have a good mic. It also needs to be comfortable because it will get used 1-2 hours EVERY day.
Bonus points if its stereo and supports A2DP audio, as getting one of those for music listening is also on the shopping list... but I'm perfectly willing to get two separate units if I need to.

Is it possible to control an Android device with a Bluetooth headset? I have a friend with a Windows phone who can listen to and reply to text messages as well as initiate calls through his bluetooth headset without touching the phone. It's very very cool, and I don't know that my Android has an answer to it. I would love to be able to do this on my Android and to use Evi through my bluetooth device. I have FlexT9 from Nuance, but it seems to require that I speak into the phone's microphone, as does Evi.
I have a rooted HTC Thunderbolt running das Bamf (don't remember the version) and a Plantronics Voyager Pro headset (same headset my friend with the Windows phone uses to control his phone).

My girlfriend has a Nexus 7 and I have a Hisense Sero 7 Pro. I have one bluetooth receiver in my car and another bluetooth headset. When either tablet is conencted to either bluetooth device, pressing the call button does nothing. I have tried autovoice with tasker with no luck. Is there anyway to get these tablets to recognize when the bluetooth button on the bluetooth devices is pressed? I notice in the menu in settings for each bluetooth device that there is only the option for "use for media audio" and not "use for call audio." If this is the reason is there anyway to modify jelly bean 4.2 to add the use for call audio option?
