Hi there,
I'm currently working on porting Android (I haven't seen anyone else being successful in doing this so far).
I think I almost have it. I've got the Source built, a custom kernel made, and put it all on the SD card. Plug it in, kernel loads, and I get the A N D R O I D text, then a kernel panic.
And all this without even making my own config for the android source (which I'm doing right now).

Anyway, just thought I'd let everyone know about this. I'll post as soon as I have it working (if I get it working, I have no other experience in this)

Neat! Which version of Android are you working on porting?

I did some research, and Gingerbread seemed like it was the best way to go. It's a pity though, there would be a lot more potential if there was more RAM. Even 512 megs should be able to run ics smoothly enough. Ah well, we'll save that for future Pi revisions :P

That's good, Gingerbread is enough to get a lot of nifty apps if you get it working ;-)

I think the main problem here isn't about the hardware limitations, it's more of the fact that I'm new to Linux.
Ah well, you know what they say, "No better way to learn Linux than to port Android to a bare-minimum arm-based mini-computer" :D

Despite the ram limitation, ICS might be worth considering rather than Gingerbread. I have installed CyanogenMod 9 (actually miniCM9) on a Sony Xperia X8 for development work, which also has 256 MB (or less - I'm not quite sure, some sources say 168MB) and have been quite impressed. Most of the apps (Gmail, skype, Angrybirds, Maps, Google Reader) work fine. Although the CPU on the pi is probably a lot slower, the advantage of ICS is that it makes use of hardware accelerated graphics, something which if the drivers can be ported, the pi can do very well.

In any case, porting android is certainly a very interesting learning project, regardless of the results.

@platinum95 how's the port going?

So what I've been doing up to now is basically a really sloppy job, getting everything done really quick and easy, just for testing purposes. First go of this sloppy job and I almost get a boot. Android starts to load, but kernel panics after about 15 seconds of loading. Which means the testing worked, and now I'm doing a proper clean job of it. At the moment, I'm merging the rpi kernel and the android kernel. Lots of conflicts that need to be resolved, so itll take a few days.
After that, I make a product config for the pi under the Gingerbread source and compile it. Then it's fairly simple - get the pi firmware, partition the sd card and load on the files.
Considering I'm not sure right now HOW to resolve the kernel conflicts, it'll be a few days before i have a working kernel :P

Maybe it's more useful in the long run to work instead on the device tree Raspberry Pi kernel, since that's based on the very latest kernel code, and Linux has Android support out of the box since 3.3.

The device tree kernel is still incomplete, though. Check out Sim Arlott's repository: https://github.com/lp0/linux/tree/rpi-linear

that is very impressive news

and from vanilla gingerbread (i guess you are working on google sources not cyanogenmod ones) we can relatively easily port cm7 and miui as well

Awesome news platinum95! Sooo looking forward to Android on the Raspberry - can't wait to test it - how buggy it might be - all I really need working is a ADB connection ;-)

That is great news. I am so glad that someone is working on porting Android to the Raspberry Pi.

I do have one question? Since the Pi only has 256MB of memory, would it make any difference using a larger swap partition? Or perhaps assigning the Swap Partition to a 4GB USB Flashdrive, so the Pi can read the OS and Swap Partition simultaneously. The way I understand it, the Swap Partition works very similar to Virtual Memory in Windows. When your 256MB of system memory gets full, it dumps the remaining data into the Swap Partition for processing as resources become available.

Sorry about the delay, I had to reinstall Arch linux and then my backup hard drive with all the 28gb of android files thinks that copying at 500 kb/sec is somewhat acceptable.
I have the android source built for Armv6 and I am just trying to get a kernel working. After that, it's just a matter of marrying the two and setting the android config files.

If you can pull this off so many of us will be so happy.

I'm happy to play with Debian, but really looking forward to this.

My father however who saw my tiny computer and decided it would be perfect to turn his lounge TV into a smart TV wouldn't be able to get past the Linux login for Debian or other distros.
A nice fluffy GUI with good user friendly interfaces will be perfect for home use.

Many thanks for putting the effort in.

Why not use the OpenElec or RaspBmc distributions for this. They boot straight into XBMC without the need to log in.

Mainly to use for web browsing and light desktop work, ie word processing.
Looked into intalling software like FireFox on XBMC and it doesn't seem to be plain straight forward.

Not looked into OpenElec.

Benefit of Android is installing any apps without having to learn basic command line. Tried to teach my dad some of this stuff but at 55, he is not so interested.

Android will be a lot slower than a pure Linux distro.
Unemployed software engineer currently specialising in camera drivers and frameworks, but can put mind to most embedded tasks. Got a job in N.Cambridge or surroundings? I'm interested!

Does it work with all hardware nowadays, or still puts additional requirements on individual modules?

E.g. with previous versions of Android your framebuffer driver needed to have support for double buffering. (which I don't think is implemented in the current Pi module).

Hi,

To run Android on machine with limited RAM, consider enabling ZRam functionality.

http://en.wikipedia.org/wiki/ZRam

Results are quite impressive.

Only works if you have enough RAM to begin with, and has a very big penalty on performance.
in other words, do not expect miracles.

Right, everything is built. But, since I'm not very good at this, it's not working (what a surprise). Getting the "not syncing - attempted to kill init" error.

So far I've tried:
Creating partitions with the debian partition, deleting all the debian and firmware files then replacing them with the latest firmware, the kernel I built and the android files.
-
Putting all the files (firmware/kernel/android) onto one partition (tried ext4,vfat and msdos)
-
Using the generic build instead of rpi.

All of these had the same result, the same kernel panic, so it seems that the problem lies in the init file, as the panic suggests.
Init.rc is as follows:

on early-init
start ueventd

on init

I've found some other sites you might find useful:
http://www.linuxfordevices.com/c/a/Linu ... ew-device/
http://wiki.kldp.org/wiki.php/AndroidPo ... RealTarget

the first one describes in details how a team ported android to a nokia phone back then with a list of android's kernel changes compared to standard linux
the second one describes android's under the hood components a bit
