Stream and play audio with Bluetooth through two Android devices? - Android Q&A, Help & Troubleshooting

I want to create an app to stream audio using Bluetooth from one Android device to another and have them both playing audio at the same time. I know that there are multiple apps that accomplish this with WiFi (like AmpMe), but a Bluetooth solution would be the most convenient. The BluetoothMusicPlayer app is the only one that does pretty much what I want but it's extremely buggy, and I've only gotten it to work for a few seconds.
From a post on stackoverflow, it looks like it's possible to make an Android device into an audio receiver through a patch on the Bluetooth package for Lollipop and later, but can it be done through an app?
(Since I'm a new user, I can't post the link to it, but the topic is titled "Android device as a receiver for A2DP profile" and the answer is by nilo.)
I'm fairly new to app development, but I would greatly appreciate it if anyone could lead me in the right direction.
Thanks.

Android as a2dp bluebooth receiver?

I know its possible to send audio from an Android phone via bluetooth to a PC using the a2dp profile. But I want to do it the other way. Connect the phone to my amplifier and send audio via bluetooth a2dp from my laptop.
I've searched but not found. Anyone know it it's possible?
I think the standard BlueZ stack can't do this. I think the Broadcom BTLA stack might be able to do this ... IF you have the Broadcom Bluetooth chip inside.
Hi Pananza,
did you have success to use an android device as a2dp receiver? I'm looking for a solution but I didn't find anything useful.
The only solution that I have found is to use the NDK to access the BlueZ stack, but I'm not sure if this is the right way.
Thanks

Using phone as A2DP receiver
Hello
I would like to do this too, have a Sony MW600, and it works perfect with laptop or my HTC Desire, but it can not be charged and used at the same time..
Will it be possible to do this on an Android that is not rooted?
Did anything ever come of this? I'm looking for an app that would allow android to receive bluetooth a2dp or whatever the basic format is (mono ok), and output audio on the headphone jack of the phone. Bass ackwards to what all other apps i've found are doing. I've always been a "special needs" user

Wanting to use Android OS in the dash of my vehicle hooked to the audio system and use bluetooth a2dp to connect to mobile phones to play media through the system.

You can transform your device into a wifi music receiver with the app called soundwire, you must install a server on your pc to stream audio from your pc to your android device. I didn't find anything with bluetooth.

Same here. More and more people are going to have "last years" android phone lying around doing nothing and this would be an awesome way to re-purpose it.
Whether it uses BT, Wifi, I don't care as long as I can stream audio from one android phone to another. What I don't want is to deal with DLNA or manufacturer built in BS. Just need google to turn on the A2DP sink profile and be done with it. The hardware is all there, just need the software to take advantage.
The next best thing is one of those BT reciever dongles/boxes. They run about $20 I think. So PSA to android developers - if you can enable this in a paid app I'm ready to buy it and I'll bet a lot of others are as well.

Did that tutorial works for you?
I've tried, but it doesn't work. My Panasonic TV doesn't see my phone, so I cannot play the TV audio thru my phone.
Any ideas?
Thanks!
I was also looking for an app like this.
For my old phones, my android sticks, ... no progress I assume ?
Waiting the same here! My idea is to buy a bluetooth transmitter, connect it to my TV and receive the audio on my phone.
I can't think that is not possible! :crying::crying:
Truck Tablet Install
Hey Everyone,
Been very curious about this as well as I'm going to do a nexus 7 install in my truck and want to be able to bluetooth additional music aside from what is on the tablet through the tablet to my speakers. Kind of a necessity due to the lack of a 3.5mm aux into the stereo. Hopefully we can figure this out!

?
I'm also looking to do this.
I'd like to be able to connect a Bluetooth transmitter to the output of a mixing desk, and then just use my phone to receive the audio (which I'd then want to save with something like tapeatalk).
This could provide a very quick method of recording gigs or DJ sets in stereo, and would be better quality than simply using the built in mic of your phone.
a2dp sink.
Bluetooth File transfer app can stream music from another phone. And this is where tha first phone works as a a2dp sink am I right? Can't we use that to built an app to follow it but using pc/laptop as the source?
Seems, that no one is interested. What a pitty, it could be really HOT stuff. For example, cheap android phone pluged instantly to a charger and to Car Audio via AUX, and You have got Bluetooth automatic pairing system for calling and music, navi etc.
Unfortunately I couldn't find solution for this, neither the app. It is strange. Some people says, that Android can not be a sink (reciever) in a2dp profile. So how does microphones from earphones are streaming audio to a phone, hmm?
Maybe someone will do it
I have a LG G3 and it does it flawlessly. It have a function called "Turn Audio Channel mode" on bluetooth settings.
I'm wondering how to do the same thing on any other andoird phones.

Possible to send all audio over Wi-Fi?

Hi all
I'm looking at getting an Android 4.0 device - not a phone as it happens - but I'm going to want to have all audio sent over Wi-Fi in order to work with something like this: http://www.lindy.co.uk/usb-portable-wireless-audio-system/20404.html
Now if I was running Lindy I'd be sure to release an app for that, but I've not seen mention of one. I don't know Android well either.
Can anyone help? I was considering Bluetooth but it turns out that lossless Bluetooth audio receivers are scarce.
Thanks

[Q] Road Veles Android car stereo add bluetooth support?

Hello all,
I'm after a little bit of guidance on how I might add Bluetooth support to an Android powered Car stereo. It is a "Road Veles" single DIN WinCE and Android device with a 7" flip out screen. The reason I bought this stereo is to run an app by the name of MSDroid. This app was to connect to my vehicle's engine management system via Bluetooth.
Can't post links yet, easy search on Google for Road Veles, look for hit on Chinavasion
The specs say it has Bluetooth, but having tested the device out on the work bench what the specs don't say is that the bluetooth is only accessible for handsfree from WinCE, there is no bluetooth for Android. WiFi via USB dongle works great. I have purchased but not yet received a combined WiFi and Bluetooth dongle. I would very much like to have this combined dongle work with the device. The Bluetooth control is not visible under WiFi control inside settings like it is in my Android phone.
Can anybody point me in the direction of where to start with this? Can I root the device and mod to add bluetooth? Is there another ROM I could run? I have done a lot of searching but can't see much at all out in internet land on this stereo!
Any help greatly appreciated! Thanks in advance,
Arran
Hi, I'm not sure how these sort of things usually work, what sort of dollar value would usually be associated with making a some tweaks to an Android build? ...
Hi again, still looking into this. Any ideas how to tweak the Android 4.0.4 OS to make bluetooth appear inside the settings menu?

[Q] Send audio from Android to speakers

Hey folks,
I just finished my house and put speakers in each room. Right now I didn't bought any kind of receiver because I'm not sure what system I should choose, so I just wired the speakers (they all go to a single place in each room).
I'm looking for a way to stream audio from my Android devices to each room/speaker. I don't want to use a single app to send audio, because most local apps (I'm located in Romania) really don't have such features (Spotify has Google Cast support, but Zonga - what we use locally - doesn't). So I need something that basically "mirrors audio" from my device; this is also great when playing games on my tablet.
Here are my conclusions so far.
Bluetooth
Is compatible with basically every OS. I can just buy a BT audio receiver for each room. The problem is that I cannot send audio from a single device to more than one receiver. So for example if I want to send audio to my kitchen and living, there's no way of doing it with bluetooth.
Miracast / DLNA
Very hard to use. There's no "simple" way of connecting/reconnecting to a Miracast / DLNA receiver without going to Settings -> Display -> etc etc each time. I don't need video, just audio. Also I cannot send audio to multiple sources.
Google Cast
Very easy to use *if* the App you're using supports Google Cast. Unfortunately most of the local apps I'm using don't support Google Cast. Also I cannot send audio to multiple sources.
AirPlay
For an Apple use this would be the best solution. Unfortunately I couldn't find any way of "mirroring" audio from an Android device to my AppleTV without rooting the device. Also I cannot send audio to multiple sources.
Media-centers
I found a lot of media-center solutions, including Qualcomm AllPlay. The decent ones allow you to send audio to multiple rooms through WiFi and specific protocols. The issue is that all these solutions are proprietary and require you to install and use a single specific/proprietary app, which is - in the best scenario - limited to playing local content from your device.
So what I really need is a solution that (in the order of importance):
1) allows me to "audio-mirror" my devices (at least the ones using Android) with ease
2) allows me to stream audio to more than one room/receiver
3) doesn't costs a fortune (I'm ready to pay $500 for this, but not more)
What's your opinion on this? Is there any solution? Thanks!
No easy way.
RealAudiio streamer-player?
Private dancer (req. root on source) streams audio from android to dlna renderer.
Well, as stated previously I don't want to use a specific app, so I think that maybe the best solution would be bluetooth? If you know any other solutions please let me know.

Turn old android phone into a bluetooth audio receiver

Hi,
I have an old android phone (Samsung Galaxy Grand) lying around. it is rooted and currently running CM12.1. I want to use it as an audio receiver over bluetooth for my speakers. I want to play the music from my daily runner (OnePlus One), streaming to the speakers via bluetooth. If any app which can do this, please let me know. Otherwise, if someone can point some Android Bluetooth API which can do this, I can create an app.
Thanks,
Sriram.

Here, I've found this after a lot of ****ing research. i don't know what it means, but please, if you can, make it. I need such an app too. Been waiting for such a feature for a really long time.
