Yes, I know this thread is in the wrong section. I tried to get this thread moved into development, only to be locked out of my own thread. So it's here for now.

This is an SDK port of Android L preview to the Nexus 7 2012 (Grouper).

First of all, this ROM is not up to the quality of other ports, as Bluetooth, NFC, many sounds, light sensor, and other features are not working.

What works:
- the boot animation ;)
- Touchscreen
- Sound (partially)
- Screen rotation
- The Settings app
- The camera
- Installing apps
- Wi-Fi - thanks, gnustomp!
What doesn't work:
- Playing some sounds, such as the Ding noise played by Google Search after recognizing OK Google
- Bluetooth
- NFC
- Google Text to Speech
- Everything else

The port is based on the system image of the 32-bit ARM Android L emulator, with proprietary binaries pulled from the stock 4.4.2 image.
The kernel used is the LegoKernel from http://forum.xda-developers.com/showthread.php?t=2664392
The kernel used in v3 and earlier is the stock 4.4.2 kernel from MultiROM http://forum.xda-developers.com/showpost.php?p=34577851&postcount=2.
The .zip packaging (and the boot animation) is based on the MultiROM repack of the Nexus 5 image from http://forum.xda-developers.com/showpost.php?p=53707461&postcount=1213
The Superuser shipped with this ROM is made by Koush: http://koush.com/post/superuser
The non-PIE fix is based on the patch by cernekee.
This ROM uses the Bluetooth and NFC apks from Cyanogenmod. Thanks!

To reiterate, this ROM is rather useless. Therefore, I have made this ROM for MultiROM (the ROM won't run without it, currently) so you can dual-boot into this and experiment. To setup MultiROM, follow the instruction on its thread: http://forum.xda-developers.com/showthread.php?t=2011403

Note that F2FS is not supported.

I have only tested this on my own device, so if you're getting bootloops, please send me a LogCat of the boot so I can diagnose the problem.

Installing:
- Back up your device. This ROM is highly experimental and may screw up stuff.
- Install MultiROM first
- Put the downloaded .zip onto the /sdcard partition
- Boot into the MultiROM recovery
- Select "Advanced"
- Select "MultiROM"
- Select "Add ROM"
- For "Choose ROM type", select "Android"
- For "Share kernel with Internal ROM?", Choose "Don't share"
- Select "Next"
- Select "Zip file"
- Choose the downloaded .zip
- Slide to flash
- To flash Gapps: Return to home menu -> Advanced -> Multirom -> List ROMs
- Select the flashed ROM, and then choose Flash Zip; choose the Gapps package
- After reboot, choose the new ROM in MultiROM's startup menu

Ok so I installed this as my secondary ROM and, well, it's awesome :D one thing that bugs me, besides there Wi-Fi and Bluetooth not working, is that every time I pull down the quick settings, Google Play Services force close ?

Thanks for this! Installed and had fun playing around with it. Can't wait to actually have a working ROM but this is a great start!

It's pretty basic, but still really impressive to see progress being made that fast! Great work, I hope OP keeps it up.

I get neverending boot after flashing..but I have to mention I'm on data-f2fs. (Other roms work fine)

Where in this thread did you read f2fs was the file system? But I have to mention, why are you stating the obvious? Lol

Er...I have Mahdi ROM on my tablet, and f2fs filesystem on my /data partition, and installed the zip with MultiRom. The ROM itself of course has nothing to do with f2fs.

    Hi guys, I got Wi-Fi working.
    The problem is that @500 Internal Server Error forgot to copy a couple of libraries.
    The libs needed for WiFi are:
    Code:
    /system/lib/libiprouteutil.so
    /system/lib/libnetlink.so
    Copy them from the stock ROM.

    There are probably a lot more other files that are missing in this ROM, so check if you get an error like
    Code:
    CANNOT LINK EXECUTABLE: could not load library "libiprouteutil.so" needed by "ip"; caused by library "libiprouteutil.so" not found
    That tells you what library is missing.

    UPDATE: proof (just in case)
    Code:
    [email protected]:/ $ ping google.com
    PING google.com (74.125.237.166) 56(84) bytes of data.
    64 bytes from syd01s18-in-f6.1e100.net (74.125.237.166): icmp_seq=1 ttl=56 time=38.5 ms

    Version 5: the "oh no, we have to catch up to the Nexus 4" edition ;)

    https://drive.google.com/file/d/0B9YZBHL7jnUDeVA5TmNyMGVGaEU/edit?usp=sharing

    - Added etc/permissions from stock ROM; Play Store and the Wi-Fi settings now work - thanks to everyone who suggested this
    - Switched the build type to userdebug from eng in the build.prop: no more flashing red borders - again, thanks to everyone
    - Added Bluetooth libraries and APKs from Cyanogenmod

    The Bluetooth is interesting: the Nexus 4 port can use the bluetooth stuff from the Nexus 5 because their processors both support hardware divide, unlike the Nexus 7. Therefore, I can't use the bluetooth apk from the preview images. I chose to use Cyanogenmod's bluetooth stuff because their APK is deodexed, and has a few more features. Unfortunately, audio support in Cyanogenmod's bluetooth framework didn't work on L: first, the Java code force-closes Bluetooth because of a missing method, but thankfully that doesn't get triggered often, unlike the native C++ code. The native code refused to load because libmedia was changed between 4.4.4 and 5.0, so I made a fake libmedia, and the native code managed to load.

    WIFI FIX

    Here you go guyz just flash this zip from recovery(Recover-->Advanced--->Multirom--->List roms--->[select the build]--->flash zip! ) and internet will be all good to go!! :good::good:

    All thanks to @gnustomp for pointing it!!




    @500 Internal Server Error
    Update-*Rom does not have the NFC.apk neither it has the option to toggle!
    *Upon flashing of gapps the TTS gives force close
    *Lags


    Still small yet significant progress so far!:D

    v4:
    - Added @gnustomp's Wifi fix - thanks!
    - Switched to the Lego Kernel: http://forum.xda-developers.com/showthread.php?t=2664392 this might help F2FS users, since that kernel's commonly used on F2FS ROMs.

    I also looked into making this flashable without MultiROM: unfortunately, with the changes, it always tries to flash to the real system partition, even when I want it to flash as a secondary ROM. So I had to Nandroid restore to get my old ROM back. Sigh. I reverted that change.

    The remaining serious issues:
    - Sound corruption for certain sounds (perhaps with different sample rate?) e.g. the "ding" noise Google Search plays after OK Google is recognized - I already copied over audio_policy.conf, so I dunno what else I need to copy.
    - A lot of Play Store applications are marked as incompatiable with device - probably needs a build.prop or a /system/etc/permissions edit
    - No Bluetooth and NFC support - I don't have a deodexed Bluetooth.apk and Nfc.apk right now; I might download another ROM and pull them from there.

    I would really appreciate if anyone with more porting knowledge can offer advice - this is my first ROM porting project.

    I get neverending boot after flashing..but I have to mention I'm on data-f2fs. (Other roms work fine)

    By the way, can someone with a f2fs data partition try to run this? Since the LegoKernel is used for most f2fs ROMs, and MultiROM's trampoline tries to mount /data as f2fs if mounting as ext4 fails, it should boot...

    Edit #2: Oh, wow. http://www.androidpolice.com/2014/0...ve-aosp-includes-support-nexus-4-5-7-2013-10/ says Android L source is released? Then I guess this ROM is now obsolete. :( Ah, well, I'll keep maintaining it until we get a proper Android L port.
