[Hero CDMA Android Development] Shelnutt2:
I'll keep this post upto date with the last on the status of the build.

I've updated the manifest and it's inline with cm10. https://github.com/TeamICS/manifest_ics_cm/tree/jellybean

Builds are located here.

Nightlies are here or here

If you are not using firerats or don't know what that is make sure you use one of the "_shrunk" nightlies.

Currently the room boots. Lots of things work, here is what doesn't:

Bluetooth (pairing)

HW Acceleration (not likely)

Anything missing from CM10

Known issues are:

Headphone + speaker plays when headphones are in

IT LIVES!

The build doesn't flash, but it successfully built. You need to use firerats as the system partition is over 173mb by itself. Not sure of optimal settings as it doesn't flash but we're getting closer.

Complete repo diff and repo status is here:

https://gist.github.com/3095432

Things disabled at build:

audioinwrapper from srec

libaac/libFDK

compiler-rt

maybe others.

Please note I haven't cleaned anything so it's quite messy and some stuff isn't pushed up to the repos yet. However it builds and that's a big step. It's off to bed and work tomorrow so I won't get a chance to work on it until the evening/friday.

Very close to a build, libaac is the only blocker, I've reached out to cyanogenmod guys to see if they have any ideas to fix aac, without completely rewritting the asm code. The problem is armv6j doesn't support smmul, clz and others in thumb mode, but armv7 (and the few devices with thumb2 on armv6t2) do. I don't have enough experience with arm asm to figure out how to rework the code to convert from 32 bit operations to 16bit operations. Also valgrind is not supported in armv6 (and can't be) so its disabled.

problems building aac, due to asm code, currently disabled a blocker

problems building srec due to audio issue, disabled

haven't ported camera

So far there is only two show stoppers, first is the audio because its changed again slightly. Shouldn't be too hard to work around. Second is cm team is still porting over all armv6 patches. Building on armv5 get stuck at audio, but armv6 get stuck on some asm code in bionic.[/sstrike] aac. AAC is being a really PITA!

So I'm sure some of you guys are watching the I/O live. For those that aren't it's offical Jellybean will be 4.1. It's got loads of new and nice features. A lot of performance upgrades and the most important thing is the annoucement of the platform development kit. It's got all the low level details and apis need to port hardware to android.

Source code will be released in mid july, which is when the real development starts.

The hardwork everyone did on ICS, jaybob, matt, evervolv team and everyone from the G1, hero and eris forums laid the foundation. The main issue that has always held the heroc back has been the drivers. We have a great .35 kernel but with ICS a lot of the framework, that is hardware <-> software interactions changed. Thats what our audio issue was at first, and the camera. Audio was fixed by porting gingerbread patches and legacy audio support. The camera was tougher but eventually fell to the power of the community! The only two major things left are camcorder and full gpu acceleration.

The PDK will hopefully provide the last little bit we need to get acceleration working fully. It's no magic but from the keynote sounds like it might provide the information we need. Or it might not. Won't know until it lands on the web.

Overall jellybean is a step further from our old heroc's but there is still almost 20k devices officially running cm7! We obviously still have a community here who has yet to upgrade so the new goal is jellybean or bust!

As more information and sources are released I'll update the thread. I plan to port our TeamICS github account to Jellybean as soon as it's released. With luck everything will compile and be in the same boat as ics but only time will tell.
