Hi everybody.
I just came back from my wp adventure for a couple of years. And it sure feels good to be back to customization
However... The nasty nasty nasty bluetooth low bitpool seems to still be here in lollipop!
I really had happily forgotten the unacceptable bad bluetooth streaming in Android, and to my surprise it still hasn't been fixed by the Google lords..
It seems funny to me, that a problem that has been described for so long on a platform, that people actually just lift their shoulders, going "oh well, that's just how it is on Android", still hasn't got any fix or even response from Google?!?
Connecting an IPhone (bvadr) or Windows phone to a good music system, is almost like using Aux. Doing the same on Android is like.. Well.. Not usable...
As far as my research go, it is the bitpool on all Android devices that defaults or max out at 32 bit. This however comes from information from the late gingerbread, early IcS days.
There have been people that have made fixes for the latter versions, but can't seem to find a fix for lollipop?
Seeing as how all wireless and so fourth has begun to win the people a little the past years, is there really not any craving for acceptable bluetooth streaming on Android?
I'm not a developer and maybe something has changed in lollipop but there doesn't seem to be any research from developers regarding this pretty big problem?
No one is unhappy with the Bluetooth streaming quality?!?
Also would love to see this raised to something like 64.
Good news, everyone!
bmc08gt and I collaborated a bit on this and have re-compiled the binaries for the BT lib in Lollipop and have two versions, one compiled with the bitpool raised to 64, and the other one to 128.
The 128 sounds anecdotally better to my ears, but feel free to try them both!
To install...
Unzip package, choose which version you want to test (128 is theoretically better).
Open a root-enabled File Explorer navigate to path: /system/lib/hw
Rename bluetooth.default.so to bluetooth.default.so.bak
Copy modified bluetooth.default.so version to /system/lib/hw (remove the _64 or _128 suffix)
Set permissions to rw-r--r--
Reboot and enjoy!
Note, this was only tested on AOSP 5.1.1. I have no idea if this works on previous versions of Lollipop.
Hey @Kev1000000
I tried using your bitpool file on my Nexus 5 with 6.0.1, but after exchanging the files, my bluetooth isn't working anymore.
Would you mind doing the same thing for Marshmallow?
That would be great, because since the Nexus devices don't support aptx and by this way it could be still better than nothing.

Hi,
I've just replace the file. This evening I verify the BT audio quality. I do this because my Xperia C4 sounds very bad on BT audiocar, much worse than my old Nexus 4.
Ok it works, sound better now but in logcat i see that bitpool range 30 to 53 during music streaming..
It is normal?
I tried this on my new Note 4 and the BT will not initialize (icon will not light up) Running stock rooted 5.1.1 Is there a different version I need or did I do something wrong? I pulled the log to try and help. also my default file is 1.46MB and this one you made is 1.26MB.
I found samsung has source code, where is the bitpool located? Are these files part of the kernel or the platform?

Hi!
This might sounds silly but do you guys know if anyone is working on something like this for android?
http://www.youtube.com/watch?v=0Nod69aTzsM
An app that makes your phone to a small guitar amp?
The iphone version has been out for a while but i cant find any info on a version for android..
The company behind iRig have been speaking about a android version but i dont think they even have started working on one yet.
It would be a really nice application! To allways be ready to record without setting up the computor and stuff like that ya know, or to just sit in the sofa with earplugs and play some sweet solos and riffs without having your gf whine about the loud music..
Found this dude trying to make something close. http://www.youtube.com/watch?v=sz-9mxWa2VA
Just checking if anyone knows anything?
Best regards and thx for all the awsomeness!
/Patrik
This would be awesome, I would definitely buy it. It's like a Line 6 pod but much cheaper.
I hope they're working on an android version. Android needs better quality apps.
Also, it's more of a multi-effect pedal than an amp. Just letting you know
I actually sent then a message on youtube to see if they were working on one. This is what I got.
This is the Mac/PC version. If you look at our AmpliTube iRig playlist you'll find the iPhone version. We're currently looking at the platform but do not have any versions for Android.

Yeah, multi-effect pedal.
Imageing all the fine stuff you could do with it!
You could use it as an effect to plug in to your amp. (maby quite alot of effects, if you can make your own sounds. And with new developing you never have to buy a new effect-pedal again.. ).
A strummer for electric guitar in the studio/rehearsal place.
Play with earplugs on the sofa.
and so on...
I'll buy!!
it needs dedicated hardware don't forget (about 10 seconds in on the video)
your phone only has one 3.5mm jack plug...and you need to plug a guitar into it and an amp into it too.
also, what happens if you've got your amp turned up to 11 and then you get a phone call?

I've bookmarked that link
I am amazed that this can be done on the iPhone but not on Android.
There is another program called Ghettoamp on the market, though the devloper admits that there is still latency (he records, then processes the sound input). 20ms I think.

Why can't it be done for android? This app is really cool.

It should be possible...
Android phones definitely have the processing power to do this. The only real problem is you're input and outputs on your phone, there's really only one... the 3.5 mm jack...
But there's maybe a way around this. And I'm not an engineer or developer or genius of any kind I'm just saying what I think should be at least possible... Everyone knows AD2P Bluetooth right? You could get you're input through it.
You use the microphone of a bluetooth headset, but instead of the microphone, you get your input from you're amp/guitar/whatever... could it be as simple as soldering a headphone jack to the PCB connections on a bluetooth headset? Dunno but let's asume it's possible.
Then you connect your phone to the headset, and you've got input... Great.
The problem now is that I don't know what android does when it has a bluetooth headset AND a normal set of earphones... Does it play from both, does it by default choose, I don't know... Say you still get output from the headphones, you could easily get the output to any speakers, seems rather pointless to use the phone's loudspeaker... This part from bluetooth input to audio jack output will maybe need a modified audio driver or something...
Once you've got input into the phone and output out of the phone, you would like to have some effects and/or amplification right? That's the point isn't it? I know nothing about programming such things but maybe a few developers who do will stumble onto this thread and share their expertise...
Once again it should be possible, but for just anyone to do this it'll be very challenging, more likely and hopefully companies like Gibson or Marshall or Ibanez (their Japanese, and this seems like a Japanese thing to do) for instance will see the need for something like this, and get working on it... If they make something like that and it works well, it'll make a LOT of money... For instance after you've bought this device, they could SELL effects, to be downloaded on a sort of 'plugin-basis'. And once one company does it, all will have some variant of the concept. I know I'd buy this...
Edit: Read about the apparent latency issue that Android has... So I don't know if it's that possible just yet, maybe ICS has bettered this flaw in previous Android versions, one can only hope...
Sorry for refreshing this thread, but I'm curious if there is such app for android available right now?

You are thinking much too complicated.
The headphone jack of phones contains another pin for the microphone. A small jumper cable can be used that allows the connection of a guitar and headphones. Check out Amplitube iRig for an example.
(this type of jack is used so you can plug in a headset with microphone)
Bluetooth or something would be nice... but the latency wouldn't be, and that is exactly the problem.. Android has too much latency,
Look:
http://code.google.com/p/android/issues/detail?id=3434
Android is not capable of this because the way it handles audio is completely wrong. More recent devices have less latency but still too much. The problem lies very deep. It is a problem for game developers too. Please star this issue if you want Google to do something about it!
Send with my telegraph
How about USB OTG connected to a Rocksmith USB connection?...
Sent from my SPH-D710 using xda premium
The Irig will work fine for this you dont need bluetooth aor usb adding yet another layer of BS to the audio streams round trip. however now that JB is out latancy is stitting around 10-12ms on adevice such as the galaxy nexus wich is completely usable (1ms of latancy = 1foot from your amp) so 12ms would be like playing 12 feet from your amp,
If you cant play like this then on stage will never work for you.
As a side note usb audio is apparently supported in JB as well now
There are now a couple of apps on Android that at least have a range of guitar effects. Delay Effects Plus (via headphone type cable) and usbEffects (USB OTG) both have an option to use Native Audio, so if you have the Galaxy Nexus running JB the latency is quite reasonable (50-70 mSec). If you have a modded ROM you may get lower latency without Native Audio option as they both read the buffer size from the OS. Of course for everyone else the latency is still an issue and varies from device to device. So to those that said they would buy .... please do!
This very issue has put me on the fence on what kind of tablet I buy. Cannot decide between note, and Ipad 3. The accessories and ItunesU has been one of the biggest attractions for me.
Litlle heads up: in their latest newsletter IK Multimedia (of Amplitube) post a few job openings, one of them being "Android App Developer"!
So they are at least working on something..

Do you got new update for futur multi effect on android
Hi Guys,
as I'm thinking of getting a new phone sooner or later, I was thinking how to use my Atrix and my Multimedia-Dock later on.
I never used the Lapdock mode or HDMI mirroring, but I bought the multimedia dock because it was really cheap and I can use my Atrix as a digital clock also.
So please forgive me if I'm asking questions that only work with the lapdock mode
My idea is:
I want to use the Atrix as a media-station for music (on storage and streaming).
As the multimedia dock as a 3,5mm line-out, I thought this might work. I'm on MIUI V5 with JB right now and just plugging in something in the 3,5mm line-out won't let me listen to any music, as I guess this line-out only works in lapdock-mode, because it will get the audio signal from HDMI (?).
I want to know if this might work with any rom that supports lapdock, because for the functions I want, I don't need the newest Android with the latest features.
Another function that would be awesome is to pair the Atrix via Bluetooth with other devices so the Atrix can play music via BT from other devices. Is this possible, too?
Like: Music on new phone --> BT --> Atrix connected to speakers plays music.
If there are any threats like this already, I'm really sorry, but a quick search didn't give me any results
Thanks!
P.s.: Can I put USB-storage on the multimedia dock when the Atrix is in lapdock mdoe?
Indeed, you need to go back to gb or atrics to fully use the hd dock.
You can connect any pendrive to those usb, phone will mount them.
Not sure about bt. Guess is possible

I recently received back an Atrix that I purchased on behalf of a friend sometime ago. I also figured it could perhaps be of use at the mother-in-laws when my son is there. I have another account with xda though it has been so long since I used the forum to post that I could not remember my username! So I just clicked to log in via G+. Its been great seeing that such an old (at least in terms of android developement) device has still got some very good support and excellent contributers. Before my Nexus4 I had a Galaxy S and that got flashed regular from the great work that goes on here.
It didn't take much reading to work out that Atrics looked as if it would suit my needs best for some simple internet use and perhaps media viewing on the Bravia the phone will be hooked to. I am hoping I may also find an XBMC build that will be stable enough to enhance the system! So today I found the time to get the basic Atrics 2.0 up and running, One or two little bugs too work out but am sure they will have been covered already. Installed FlashFox browser to make sure flash works without any hassles and just completed a rom backup and upgrade of the kernel to 14-02-05. The difference is noticeable straight away Krystian, good work.
I'll try to keep up with my project and how it goes. How is your project working out muhski?
Thanks again to just about everyone within this forum who has posted, I narrowed initial problems down quickly due to the very useful guides and information
setup restrictions
So I set up everything up nicely using the atrics ROM. Due to the TV and setup at the mother in laws, using the stereo out on the dock was not viable. This forced me to roll back to Nottatrix4g for a quick fix of using the HDMI to pass sound as well as audio. As a result I have a nice portable setup which will reside at the mother in laws for my son to use and perhaps his grandad too. I kept the ROM install as slim as possible without removing any functionality that may be required if we take the system on holiday for example. I installed several addons in xbmc and went through each to check the ones that wouldn't work easily for example asking for an external player, (the ones that did work easily all diverted to mxplayer). I added both Firefox and dolphin for flash based browsing, a couple of the games he plays on my Nexus 4 and an emulator to play the games I still have from the NES. The emulator is tied into wiimote for an easier experience for him although I would have preferred a more manageable pad but since that's as good as free.
So the the real test will start tomorrow, my main concern would be the system recovering from any crashes but up to now with the exception of xbmc occasionally closing, I have only had one issue with Bluetooth and the mouse showing paired but not. I deleted the db and that resolved the issue which I was unable to replicate.
So my experience would be to tell you if a similar project was looked at, check your hardware and see how the audio can connect best. If you can only do audio with HDMI stay on 2.x.x ROM, if you can stereo from the dock into the TV by RCA's or an amplifier you can use atrics ROM or a 2.x.x based ROM. Other than this you shouldn't need to spend too long finding a good use to a redundant Atrix.
The xbmc version came from xbmcandroid as the official xbmc does no longer support tegra² chips. If your reading this regarding a newer phone then the official version may suit you better.
Thanks to everyone who has made this possible I will try and name everyone and their apps in a review of the system in the hands of the young and the old in a week or two!

Did you ever get around to making the list of applications used in your media center build?
Also, does the remote control work with it?
Hello Guys,
I have bought a Dell Latitude t02g Table. The specs looks great - Windows 7 Pro - 1.5ghz atom processor, 2 GB Ram, 64GB SSD.
I think the specs are great but its just too damn sluggish when i run facebook or any flash games on it. very unresponsive on normal browsing.
I think this tablet can be great on Google Android x86 platform but After doing a lot of research - I see that people have installed LUBUNTU on it or windows 8 on it and are in a compromised situation. Where Windows 8 has blue screens and etc and moving on Lubuntu, has limited the functionality of he hardware graphics and rotations.
So much money paid for a device that promises a lot and so much disappointment .
I just wish if we could have a forum for this device where the XDA Team can make something super for this device - maybe an android port over that fully works and makes teh tablet smooth like other tablets.
Do you think there is something already out there that has fixed the tablet and makes it shine like a star as advertised? or will there be further enhancements on this and i can wait for it?
Or should i just sell it off for literally peanuts and forget about it
Any help/ hints would be great.
Thanks
AJ
delldell latitude 10 st2
I also wanted to know if for the dell latitude 10 st2 there was solution?
Try the latest windows. That's what I did. To make good use out of it. I installed Kodi n hooked it up to my TV via HDMI worked well. N then sold after a few weeks. Let me know how it goes
There's a fork of android for x86 architecture (http://www.android-x86.org/ ). Some year or two ago I tried few of provided builds but with mixed success. The issues is that bundled drivers are either generic and performance is bad, or different builds have different modules working ( like WiFi but no sound or sound but no WiFi)
It's not that difficult to get two kernel .config files from two most "working" builds and merge them together and build a new kernel, but the process itself is very time consuming (you have to compare files option by option manually, automerge is not an option in this case)
Builds were tegav2, asus_laptop and eeepc
Looks like http://www.android-x86.org/ project moved quite far since that time so maybe you want to give it a try. It's rather brick-safe and you can always go back to Windows/Linux.
Speaking of which, right now my ST has Win10 installed, but performance is bad. I'm thinking of installing clean ubuntu (from Minimal CD) with i3 WM to get maximum out of that hardware. On other laptop with similar specs such setup looks very promising
Hi there,
I hope I'm posting this request in the right section.
I have recently bought myself an Xtrons TD730a Double Din Head Unit, I would post a link to it but unfortunately I am unable to as the forum won't let me. You should be able to find the unit in question with the help of google though.
On the whole I've been pretty happy with the device. The main downside I have discovered though is that it appears to be running a rather cut down version of Android 4.1
It is unable to communicate with my Bluetooth OBDII device, which having read through a few of the other threads on here seems to be a common issue with many of the Android Car Headunits.
The other, more annoying issue I've noticed is that when I am streaming music from my home server over 3G, it doesn't seem to support gapless playback when changing to the next track or Audio Chaining or whatever it is known as. I use exactly the same apps and set up on my LG G3 and gapless playback works fine on that.
From what I can gather, the necessary APIs to support Audio Chaining were added in to Android API Level 16 which was introduced around the time of Android 4.1 so this Headunit should support it.
I'm wondering, if the Headunit is running a rather cutdown version of 4.1, is it possible that Audio Chaining support has somehow not been added to it's supported APIs?
Is there a way I can check if this is the case? And if so, can I get them added in somehow? I'm guessing that a good place to start would be if there is a root method available for this device?
I hope it was OK to post these questions here. Please let me know if I should have posted them elsewhere.
Cheers,
Jim

Even though its an 7 inch screen it is the same as the AN21 head unit internally. So it doesnt support obdll over bluetooth. Try getting the wifi version that it works. Try the same rooting method as that head unit.
@ little off topic question
Im sorry I do not have the information on that for you but it shocked me when you said that it didn't work with your phone over bluetooth . I was thinking about buying this model and want to make sure that the Bluetooth is able to stream my music and also make phone calls from the dash !? Is that possible with this unit ?
Another question I had is about the sound quality
The watts are not listed online so does it get loud and clear or do you need an amp with this unit
Again sorry I couldn't help ( sorry for asking a bunch if random stuff )

Thank you so much for pointing me in the right direction :good:
I've had a good read through the AN21 head unit thread. I've ended up upgrading the system software to version 2.8.3 and I've also managed to root the device.
The result is now that I am able to play my music over 3G without there being any annoying gaps between each track.
As you've mentioned, it still doesn't support OBDII over bluetooth and this does turn out to be a hardware issue rather than a software issue. In fact, the software itself does clearly support OBDII over bluetooth, it's just the hardware version of my bluetooth controller that doesn't support it.

The head unit does connect to my phone over bluetooth, I never said that it didn't. I was referring to a bluetooth OBDII adapter (for reading out diagnostic information from my car's ECU) that does not work with the head unit over bluetooth.
I've not actually attempted to make or receive any calls over bluetooth, or to stream any music via Bluetooth, but it is my understanding that the head unit does support these features.
It is probably a good idea to have a proper read through the"AN-21 U" - Unbranded 6.2" 2 DIN Pure Android 4.1 Car Stereo Radio Head Unit [ROOTED] thread available on here in the Android Development and Hacking --> Android General section as it seems as though people have had different results with regards to sound qualities depending on which software version / MCU version they are running on their unit. For what it's worth, I've left my MCU version untouched as it looked as though it was a whole different ball game to change MCU versions as apposed to simply changing the software version.
I can't remember off the top of my head what the speaker wattage outputs are, I seem to remember something around the 45X4 mark, remember those are peak ratings. I do have an amp running a sub woofer in the boot of my car but the rest of the speakers, which are just the standard speakers that were supplied with the car, are powered directly off the head unit.
I've got to be honest and say, I don't think they go as loud as they did with my previous head unit, a Sony MEX-BT3100U, so I will probably look at amping them at some point in the future, probably after replacing them with some good quality aftermarket speakers.

It is probably a good idea to have a proper read through the"AN-21 U" - Unbranded 6.2" 2 DIN Pure Android 4.1 Car Stereo Radio Head Unit [ROOTED] thread available on here in the Android Development and Hacking --> Android General section as it seems as though people have had different results with regards to sound qualities depending on which software version / MCU version they are running on their unit. For what it's worth, I've left my MCU version untouched as it looked as though it was a whole different ball game to change MCU versions as apposed to simply changing the software version.
I can't remember off the top of my head what the speaker wattage outputs are, I seem to remember something around the 45X4 mark, remember those are peak ratings. I do have an amp running a sub woofer in the boot of my car but the rest of the speakers, which are just the standard speakers that were supplied with the car, are powered directly off the head unit.
I've got to be honest and say, I don't think they go as loud as they did with my previous head unit, a Sony MEX-BT3100U, so I will probably look at amping them at some point in the future, probably after replacing them with some good quality aftermarket speakers.

Anyone know if it is possible to root the Xtrons TS702L or how to upgrade it ?
Some of you might already be aware others maybe not, with the latest build of the "Headunit Reloaded app" you can now enjoy the Android Auto experience on almost any device. The app can be found in it's own thread, together with all the how to's and all the support: https://forum.xda-developers.com/ge...ndroid-4-1-headunit-reloaded-android-t3432348
Currently confirmed units capable to run the app:
- RK3188 based units, but only through Wifi connection
- AN-21U, xTrons, will work with USB, but only using Software decoding (occasionally that can produce some H264 decoding glitched)
-Allwinner powered devices
- Intel powered Joying units
Possibly other devices as well.
I have just updated the free trial app version to match the latest release so trial now also include all the features from the main build for those who want to try it out on their devices.
Can you tell me what this actually can do for me?

The app allows you to convert your Android powered headunit into an "Android Auto" compatible headunit, instead of buying an expensive Sony/Pioneer/Kenwood which can run Android Auto on it, you can use you existing unit to do so.

I dont understand the point - a full Android headunit can do so much more than Android auto.
Its a bit like saying "theres this great app that reduces the functionality of your device and makes it dumber".
Or have I missed something ?

Hi.
You are half way right, using "Android Auto" is way more limited than using a full blown Android, but it has some advantages as well, like for example it integrates SMS control from the headunit and data used between the phone and the headunit isn't classed as tethered data, which comes VERY hand for those who have included allowance in their phone package but not usable for tethering. Meaning you can listen to online streams (radios) on the road without tethering to the headunit. I know you can do that over A2DP as well, but most of this devices have a very cheap and bad quality A2DP receiver making listening to anything a painful act rather than an enjoyable experience.
Others will find the simplicity of the app appealing as well as the fact that it removes all the unnecessary notifications (distractions) while driving, but this like everything else related to Android Auto VS a full Android headunit is subjective.
Everybody has different needs, different preferences and so on so while some people will find Android Auto to be the best alternative possible others will say it's stupid to limit the functionality of your headunit. I tend to agree with both of them and both have valid points, I thinks it's down to individual preference.

Yes, you make some good points actually, some of which I find quite appealing. I kinda fancy some of those features on my Android headunit without running Android auto.
Just seen youre the dev, I wasnt trying to dis your project, just couldnt see the point, although I can now and yeah, its all subjective and down to personal preference.

No worries haven't considered it like that, I like to be as objective as possible, same with AutoMate, I think it's a great app and usually when I'm asked to compared it against AA I try to do it in objective way.
At the end of the day it doesn't matter which approach somebody takes until the it doesn't start with the i letter

Maybe your next project should be bringing some of the advantages of this one to people who dont want Android Auto on their Android headunit, but want some of the benefits youve pointed out, like tethering data classed as phone data and SMS control from the headunit ? Sort of a halfway house. (I m joking but kinda serious too).

Hi Emil,
I've sent yiu an email as well.
I'm in India and I just bought an android head unit. Its Allwin. When I go on the app store, I can't download the app, its not compatible.
Please tell me what to do?
@Emil Borconi , confirmed working on mtcd ha 1.63c with Hal9k_ Nougat ROM on RK3188 1GB unit over wifi! Purchasing, best of luck.
hey, it's working fine, but is it possible to change resolution to 1024x768? I can work only on 800x640, and the next one is 1280x720, which isn't working properly on my HU
