[Q] AOSP patch for Samsung Galaxy S

I just stumbled upon http://forum.xda-developers.com/showthread.php?t=757000&page=18 but am apparently not allowed to post there (due to a 10-postings rule… how interesting, considering *real* developers _despise_ web fora and hack instead…).
I cannot help but wonder whether one of these people has seen a patch against AOSP, if any is required, that enables building something that will work on the device (it’s probably bought in Germany, if that makes a difference).
I’m at a point where I can regularily run “repo sync” and “repo upload”, have a number of changes of mine accepted into AOSP and Android itself, and can run “make” in the top-level directory to get something that works with the emulator. As far as I can see, the hardware support in AOSP is limited… there’s samsung crespo, but I can’t figure out if that’s what I need.
And yes, I am really interested in flashing the HEAD of the AOSP on an actual hardware device (since it’s also sort of a technology preview, so my cow-orkers can evaluate all sorts of things). Especially since it’s open source.

Possibilities of a Rockbox Port for WP7?

Hey, XDA. This is a copy and paste of a post to '/r/wp7dev' on Reddit I made a few minutes ago, and I'm not yet able to post links sadly.
I took out my Toshiba Gigabeat S the other day, which I've pretty much abandoned when I got my Focus. I kind of missed the amazingness of Rockbox.
The short time that I had a loaner iPhone 3G, I had installed iDroid on it and the Rockbox for Android port too, and it worked well. (I was the first person to get Rockbox working on an iPhone, [kind of!])
So now, I'm thinking about how cool it'd be to have Rockbox on my shiny Windows Phone 7.5 Samsung Focus...
I'm not a programmer by any stretch of the term, aside from dabbling here and there, but I do have the whole VS2010 for WP7 and an official student dev unlocked phone and all that, and got to tinkering with the source from Rockbox's Android port (I had this linked, search for Rockbox Android port). (I figure it'd be the most sensible to try with their Android port than any of their device specific variants.)
Obviously, I have no idea what I'm doing. I was able to find a porting guide for Android to WP7 APIs (I had this linked, search for Windows Phone Android mapping) and it looks like a lot of the objects translate well, plus Java and C# are fairly similar to each other, and are translatable (also linked, search for Java C# comparison).
I'm aware of some of the limitations with file system access and native applications, etc. with WP7, so I know the whole porting process won't be a 1-2-3-done kind of deal. But it definitely looks doable.
It seems that something like this might need an Interop-unlocked device for it to fully run, but I figure anyone who'd even want Rockbox would already have that done.
Rockbox would be great for WP7 because:
- it supports gapless playback
- it supports a gigantic variety of file formats
- crossfading is lovely
- EQ controls are superb, as are compression controls and balance and whatnot
- it has an excellent set of plugins like oscilloscope, vu meter, etc.
- plus, it'll look really cool Metro-fied.
If anyone with interest is able to help out with this, let me know. Then who knows, support for streaming gapless from a media server could even be done down the line.
tl;dr: a Mango/Metro-fied WP7 Rockbox using the source code from the Android port could be a super amazing thing for the audio playback options for the platform. Any assistance in doing this would be spectacular!

Rockbox for Android is not something I'm familiar with; the last time I looked at RockBox it was a full ROM replacement. You could technically do that with an HTC phone, I guess, but it would be very difficult to create the ROM and a complete waste of the hardware's other capabilities.
Integrating Rockbox functionality into a WP7 ROM is probably closer to what you're thinging of, but it still won't be easy. WP7 doesn't allow apps to replace core functionality built into the OS, so you'd need to create a custom ROM that uses Rockbox in place of the built-in media player.
I don't know how hard this woul be, but don't assume it would be easy. Android is pretty much nothing like WP7 internally. Android uses a Linux core, and apps for it are written using a Java variant or various native programming languages available for Linux. WP7 uses a Windows CE core, and apps for it are written using managed code or Windows native C++. Typically speaking, to port an app between the two system you must completely re-write it.

I do know that Windows Phone 7 uses C#, which is structurally similar to java. At that point it'd be a matter of porting over the java to C#, then figuring out the API equivalents. Still though, I don't know how possible this'd all be without native access to the device.

LatinIME API Levels

Hey,
I've recently dived head first into android app development. I was messing around with the LatinIME that is available on the the AOSP source code tree.
I've managed to get it working fine on my 4.0.3 device, but i'm having serious problems trying to get it to work on devices with lower API Levels.
It's got lots of deprecated packages inside it, so i believe there must be some easy way of getting it to run without FC's on older devices, but i just can't figure it out!
Other people have already done this, as it's available on the market, and i'd appreciate any guidance anyone can offer.
Is it just a case of rewriting the 4.0 only functions?
Thanks,
Jack.

[Feature request] phone/phablet (nexus 7 2013 lte) as bluetooth headset

Can we have nexus 7 2013 lte act as bluetooth headset and have phone book access profile please.....
www.bluez.org they have the whole source code to put this in to any rom, i do not know how to put but someone who knows i think should be straight forward
also there are roms from huifei who manufactures car stereos with bluetooth functionality in them and they are based on android ... http://forum.xda-developers.com/showthread.php?t=2660662
can we have this functionality please in nexus 7 ?

Last I checked, the bluez stack was missing some important Android functionality, so getting this functionality would require sacrificing other capabilities and it would also require a LOT of work.
It would also probably make life a living nightmare for some of our device maintainers.

There is source code available for a product called carpod, and android car head unit which also has this bluetooth functionality... i downloaded the source code, and it has gradle files etc... i have no idea how and what to look in to the source code... any suggestions where to look? how to open the complete source code in android development studio etc?
the link for that source code is under Helpful Links section -->> http://forum.xda-developers.com/showpost.php?p=55200512&postcount=1
i really hope a developer can just add this functionality which is already implemented in many available car head units running on android...

Is it possible? Yes.
Is it more work than we have time for? Absolutely
To do so would involve either adding a new profile to the Android BT stack (none of us have any familiarity with it) or dropping in BlueZ, which has some really nifty features (such as native DualShock controller support), but its support for other important features (like Bluetooth LE) is, if you read their changelogs, a heavy work in progress and experimental. Which means that if we did this for your niche feature, we'd break widely used functionality (like communication with Android Wear watches). There's also the fact that EVERY device maintainer would have to make changes to their audio routing configs to support this, and trust me, messing with audio routing is a MASSIVE PAIN IN THE ASS that no one wants to mess with.

BlueZ for Nexus 5

I'm wondering if there is anyone out there that might be interested in building a "stock" ROM for the Nexus 5 that uses the BlueZ bluetooth stack instead of the default Bluedroid stack. It should be very simple, as the BlueZ for Android project has done most of the work, including building the kernel. It looks to be as simple as downloading the various source files and compiling. I was attempting to do it myself but I couldn't ever get Linux installed on my PC. Well, I got it installed but could never boot into it. I feel bad asking someone else to build it, but like I said, my PC setup seems to be Linux-averse and my understanding is that this is a simple build.
The impetus for this is that I recently upgraded my car stereo to a bluetooth-enabled unit but I can't transmit the track metadata. Even though the head unit supports AVRCP 1.3, and the Nexus 5 should also support AVRCP 1.3. I'm unlikely to get a firmware update from the stereo manufacturer. All my reading on the issue suggests that bad things happened for Android bluetooth when Google switched from the BlueZ to Bluedroid stack. I'm hoping that incorporating BlueZ in my phone might just increase compatibility between my phone and head unit.
The relevant links for making the build are here:
