Testing ROM Images in the SDK Emulator!

I started looking at Android Development and got the whole Dev kit and the Eclipse enrionment setup and working fine.
The question I have is that I would try different apps I develop on the different ROMs available.
How do I get any of the new ROMs, like the HERO ROM ZIP files I can download to run in the emulator or is it even possible?
Im assuming that the system.img file in the SDK id the file I need to replace or re-create, but how is this done?
I am a noob to the develop stuff so step by step instructions would be much appreciated.
I also think this would be great for other developers and ROM makers to be able to test in this way.
Thanks
Simon

Hopefully THIS one dont get closed, it IS asking a development question...anyway,
I would like to know this as well. I would like to test things myself (getting better at manipulating them), and would like to know what he is asking as well.
Thanks.

I don't think this would work, as the ROMs are hardware depending, me thinks. Or at the least the kernel and drivers are.

maybe this will help, maybe not, just an emulator primer, so maybe people can jump on board with this

creating an AVD:
android create avd -n your_chosen_name_here -t 2
When you create an AVD, the android tool creates a dedicated directory for it on your development computer. The directory contains the AVD configuration file, the user data image and SD card image (if available), and any other files associated with the device. Note that the directory does not contain a system image — instead, the AVD configuration file contains a mapping to the system image, which it loads when the AVD is launched.
By default, the android tool creates the AVD directory inside ~/.android/avd/ (on Linux/Mac), C:\Documents and Settings\<user>\.android\ on Windows XP, and C:\Users\<user>\.android\ on Windows Vista

to run your newly created AVD:
emulator -avd your_chosen_name_here
maybe this will help, but I'm guessing everyone here already knows all of this.
references:
http://developer.android.com/guide/developing/tools/emulator.html#starting

Yeah, I understand that you can specify the AVD.
The only thing now is to edit the AVD to point to a different image. This is easy!
The system image file is a *.img file.
So how do we get our ROM images compiled into the IMG file format?
There must be a tool, but I cant find anything.
And what hardware does the emulator, emulate? Maybe it ignores the hardware specific calls throu an API so the ROM image target hardware shouldn't matter.

I just started messing around with rom's and after I build one I put system.img userdata.img and ramdisk.img from my /mydroid/out folder into the sdk's image folder and start the and it uses the new rom when I start the emulator

thats the easy part
do a nandroid backup
copy the sdk/platforms/android-1.5
to something like sdk/platforms/MINE
go to your AVD directory AVD/whateveryoucalledit
open up the config.ini
edit:
skin.name=HVGA
skin.path=platforms\MINE\skins\HVGA
image.sysdir.1=platforms\MINE\images\
go to your nandroid backup on your sdcard
copy system.img
go to sdk/platforms/MINE/images/
and paste the nandroid system.img
now run your AVD and it will boot that system.img
im running CyanogenMod rom right now in the emulator
hint* number pad 7 with numlock off in the emulator is how to open up the hardware keyboard

Awesome. I'll be giving this a try later.
One question: The apps are in the system.img file on the SDK images as far as I can tell. What do you do with all the apps in the new ROMs?

whatever you want to do with them, they're all there, even android market works perfectly

And where are you guys getting the system.img file from?
The ROM zip files dont have them.
Sorry....Im noob to this. LOL

OK, Im confused. Can you just unzip the ROM files and place in the folder that you point using the same folder structure?
OR
Do you have to have a system.img ?

Another thought:
I dont want to have to install all the ROMs just to create a Nandroid backup to get the images. There must be a way to create the images from the raw files in the ZIP files.
Any ideas?
UPDATE: The same technology used by Nandroid itself!

The google android emulator included in the google android sdk is limited. Although you can use 'adb push' to upload more tools, but one has to do it again next time. Follow the steps to create a enhanced system.img:
1. system.img is yaffs2 flash file system, so firstly you need the mkfs.yaffs2 tool, download it in the following link: Release Android Yaffs2 Tool (Both X86 And ARM). One has to be a registered user to download the tools.
2. use the 'adb push' to upload tools to android emulator, executables in /system/bin/, libraries in /system/lib, one can also create folder. One need change the file mode necessary.
3. upload the ARM mkfs.yaffs2 tool, use the following command to create system.img: # mkfs.yaffs2 /system /system.img
4. download the system.img to local with command 'adb pull', replace the system.img in your emulator folder/tools/lib/images/

so it seems like it would be just as much fun doing a nandroid backup
*edit*
so now the real question is, how do we go about ripping out the nandroid functionality to be able to do this locally?
*edit 2*
it is the mkfs.yaffs2 tool
Usage:
mkfs.yaffs2 yourdir yourimage

NANDROID - CYGWIN DIRECTIONS (not not not, I repeat, not fully tested and verified yet)
Changes so far if you are using cygwin:
1) Make sure you have the 'netcat' and 'gcc' packages, else just run cygwin.exe again and get them.
You can test if you have them by running 'which nc' and 'which gcc', both commands should return /usr/bin/<command>
2) Compile the mkyaffs2image executable.
Inside the extracted nandroid archive directory, goto the tartools\yaffs2\utils\ directory (inside a cygwin prompt) and type 'make'.
This should generate a file named "mkyaffs2image.exe" which you need to place somewhere on your path.
(Hint: If you haven't downloaded the Android SDK, abort now. Wait for more explicit directions... Else, place the .exe where adb is, since it should be on your path already)
3) Edit the nandroid.sh script. (else you get a permission denied error when the script tries to run the dump_image-arm file)
Find the line:
adb push ./$tool /cache/$tool
Add the following line after it:
adb shell chmod 777 /cache/$tool
4) Make a managed mount named /tmp (else windows will puke on the long unix filenames with colons, etc)
mkdir /tmp
mount -o managed c:/cygwin/tmp /tmp (Note: change c:/cygwin to be the directory cygwin was installed to, you can find it by typing 'cd /' and then 'explorer .')
5) Follow the standard "tar + mkyaffs2image" directions to generate the last three .img files. They refer to the /tmp directory which you created in the previous step.
Viola! Looks like I have a complete backup image now...

Is this for Linux (which I don't have) and if so, is there a Windows version?

short answer: yes its only for linux
long answer is a plea for help i posted in the nandroid thread about it:
I was wondering if there was a method to use the yaffs3 command to make a system.img from an unzipped rom placed on the sdcard through ADB, from what I've seen nandroid is almost exactly what I'm after.
The issue of why I can not just do this through linux, i can. I just want to be able to do it through windows some way without loading the entire rom on the phone and nandroiding the system.img out.
Either the aforementioned method, or the ability to mount a portion of my computers hard drive as a recognizable mountable partition within android running on the usb connected phone, loading the rom on that partition, unzipping it there, running ADB and making the system.img. But this way seems to bring up more problems than it's worth.
Or.. running the make yaffs3 command through ADB running the emulator with the rom unzipped on the virtual sdcard. This would actually be the best option as it would not require an actual phone.
I hope someone can help. Thank you very much.

Click to collapse
hopefully someone knows the answer, I'm still trying though.
so on windows we would adb push the update.zip to the sdcard on the emulator
unzip it on the sdcard, there are apps for that
adb shell mkfs.yaffs2 sdcard/<extractedzipfilename>/system/ sdcard/system.img
adb pull the newly created system.img and proceed to load it in the emulator
i know im missing a ton here, please someone correct me

I'd love to be able to run these images in the emulator on windows!

Hm, the emulator just hangs on the ANDROID.. message, similar to when the standard system.img was in.

anyone figure out how to do this on a mac?
thanks if anyone can.

I found this somewhere else and take no credit for it. I did shorten the steps.
Of course this is once you have the sdk installed on your mac
1. Run Terminal, and change to the 'tools' directory of the SDK (or add the tools directory to the path settings in ~/.profile).
2. Type './android list target'
3. Note the 'id' number of the '1.5' target (in my case it's '2')
4. Type './android create avd -n enhanced -t 2' (substitute 2 with the target number determined above if required)
5. You will be prompted to create a hardware profile. {You can leave as default no}
6. Use nandroid to create a backup then copy system.img
7. Copy file to ~/.android/avd/enhanced.avd/system.img
8. You're ready! Type './emulator -avd enhanced' to run! Note: inital boot may take a few minutes!

Can anyone post up the
Android Yaffs2 Tool (Both X86 And ARM)
for download? The above link doesn't work. I did a google search and all the D/L links are referring to the same location.
thanks!

How to emulate cooked rom?

Hello.
I cooked a rom with some changes and my question is... How can I try it? I know there's a metod to emulate roms, but I want to check if the update.zip is signed correctly, so what I want is to emulate recovery or fastboot, but I can't.
Somebody knows how to do it?
Thanks.

should be moved to Q&A
but i have the same questions i went through everything emulator related on the android site and through the command line help functions and i got as for as creating a sysdir image and i got stuck where you do the kernel image .....

I only found this:
http://android.modaco.com/content/g...p-and-running-a-full-rom-with-the-market-etc/
But I can't enter in bootloader or fastboot with [Home Key], [Back Key], o [Menu Key] While it's loading.

what SDK are you using (HUGE DEAL)
if your using the latest SDK have you precompiled your AVD profile (android virtual device) see http://developer.android.com/guide/developing/tools/avd.html#creating
if you have compiled your AVD and pointed your emulator at the correct AVD profile
http://developer.android.com/guide/developing/tools/emulator.html
if your booting an actual update.zip youll have to flash do a NAND dump of the phone and copy your NAND files to your pc and boot those through your emulator to ensure it runs correctly
(i only say this because i dont know if its possible to enter recovery mode straight from the emulator)
you place your system.img and your AVD stuff in the same folder
9. Copy the above file (referring to system.img{which would be the dump of your /system folder in a img format} to the location of the enhanced.avd directory ('C:\Documents and Settings\<user>\.android\enhanced.avd' on Windows XP, and 'C:\Users\<user>\.android\enhanced.avd' on Windows Vista).
10. You're ready! Type 'emulator -avd enhanced' to run! Note: inital boot may take a few minutes!

I may be dead wrong, but you can extract a .img file to the system folder contents by unyaffs-ing it, so I assume you could do the reverse...maybe.

im not super linux familiar... im learning as i go and reading everything i can about it
thanks for the info :thumbsup:
so you mean
su
mkyaffs /system
or
su
mkyaffs /block/devblock/mmc0blk (i think thats system idk for sure right now tho)
just checked the unyaffs google code page... says it only supports unyaffs right now not making system.img's.....
but theres links for a mkyaffs so maybe thatll do it
---checking google site sdk site for info on compiling system.imgs maybe theres a tool included---
NOPE NOTHING!
umm
i have an idea for you man
boot into your environment and then adb shell in and just try it because the whole image that you booted to should be read write
once you boot into your emulator load a sd card file with the mksdcard commands
http://developer.android.com/guide/developing/tools/othertools.html#mksdcard
then your gunna get your adb and
adb push cyanogen1.4recovery.img /sdcard
adb shell
$ su
# flash_image recovery /sdcard/cyanogen1.4recovery.img
#reboot recovery
and see if itll do it that way if it boots into recovery with the custom recovery.img sweet action your good to go grab your ADB window and
adb push (your custom rom).zip /sdcard
adb shell
#reboot recovery
then select choose update.zip to flash and choose your custom rom and in theory it should flash it to your Readwrite system.img........
someone anyone correct me if im wrong cuz im gunna have to try this when i get home
THIS IS ALL IN THEORY I HAVE NOT TESTED NOR DO I KNOW IF THIS WILL WORK JUST AN IDEA FOR YA

This is NOT a flashable zip file.
It is a file collections for ROM Dev.
09-22 15:48 update patch:fix gps FC & vold issue & Youtube HD no video issue:http://www.megaupload.com/?d=7YJ6B7UR
flash it with ROM Manager or recovery menu.
Known issue:
1.camera can not work
2.Location,CarPanel FC sometimes.
Thanks all Dev from XDA! This file pack is based on DesireHD leaked RUU/Dump.
Requirement:
1.Desire Phone
2.custom recovery(AmonRA,ClockWork)
3.parted SDCARD with ext2/ext3, ext partition size not less than 512M.
4.radio version great than 32.42.00.32U_5.09.00.08
use it with follow step:
1.unzip the ownhere.DesireHD.zip
2.reboot your desire phone to recovery mode,for example:"adb-windows.exe reboot recovery"
3.wipe data,system,sd-ext
4.adb connect to phone, for example:"adb-windows.exe shell"
Code:
mkdir /sd-ext
mount /sd-ext
mount /system
mount /sdcard
5.push ownhere.desirehd.system.tgz,ownhere.desirehd.sd-ext.tgz,ownheredesire_v2.0_acekernel.zip to /sdcard
for example:
Code:
adb-windows.exe push ownhere.desirehd.system.tgz /sdcard/
6.adb connect to phone
Code:
cd /system

/system/lib/hw/
/system/lib/egl/
build.prop
and some files i forgot...
all of these files can be restore from leaked RUU(But may be crash the system)
HOWTO extract file from DesireHD leak RUU 2.15:
run RUU_Ace_HTC_WWE_1.15.405.1_Radio_12.21.60.12_26.02.00.09_M_test_148662.exe in Windows box.Then some dialog appear(which include a 'next' button), look for your windows' temp dir, search the newest dir created by RUU, then copy rom.zip(about 277M) to another dir(or RUU will delete it automaticly).
send this rom.zip to Linux box,
in Linux box, unzip rom.zip, then
Code:
mkdir system
mount -o loop,ro system.img system
all files in system dir. you can simply copy files from it.

Because it splits the .apk (app package) into two parts, the .apk and a .odex file. Usually, for the phone to use an app, it has to decompile the .apk and get the parts it needs to run the app. With the odex files, which stands for "Optimized Dex" the startup time is much faster since the phone doesn't have to perform any optimizing at startup/runtime, and because of that, it also uses less CPU power, and thus makes it faster, smoother, and battery life is increased.

OK. So what is this tool?
This tool doesn’t deal with partially odexed ROMs. This tool is for odexing a ROM that is completely DEODEX.
The benefits? Faster boot, smaller imprint on /data/ partition, overall faster feeling
The myths? I can’t theme ODEX! WRONG! You can theme odex just fine! Just use baksmali and smali.

Added by me:
You have finally settled on a ROM that you want to use for some time without an intention to modify it further
You will need about 100 MB free space on system (my free space decreased from 160 MB to 96 MB after the completion of the process) To free some you can delete some apps from /system/app or move them to /data/app with a root file explorer (do not forget to set the correct permissions afterwards) or even better: to move your /system/lib folder to the lib partition without reflashing the ROM (see below for details)
Tested on Fallout 5.0 and Virtuous Infinity 1.35 with my Tweaked3 8.6 kernel. If you are using this it is at your own will and risk
NOT WORKING on CoolDroid and Sabsa Prime 6.5, probably because they have mixed framework from different Sense versions! Do not do on other similar ROMs only on ones with an original (even modded) framework!

Extract the archive in the folder where your fastboot executable is. This is not a flashable zip!​orDownload 2: b2b_lib_bootimg.zip
md5sum: 4bb4d44506eae5f247b69f9c5663e3a8​The zip contains boot images of my B2B kernel with /system/lib support (I am not advertising it but this are the files I have ready, you can use a Stock kernel as well). There are 2 of them:
Sense4_lib_boot.img - for ALL Sense 4 ROMs (except VIrtuous Infinity)
Sense36_lib_boot.img - for custom Sense 3.6 ROMs
Extract the archive in the folder where your fastboot executable is. This is not a flashable zip!​NOTE: your ROM has to be on the same version of the kernel before the procedure, otherwise your WiFi will stop working. Or you will need to download the zip from the kernel thread and copy the modules to /system/lib/modules manually giving them right permissions (644 or -rw-r--r--)​Procedure:# Connect the device to PC, open Command Prompt (cmd) and browse to the folder where are your adb and fastboot executables are (example: cd C:\android-tools)
# Reboot to Recovery (4EXT recommended)
Code:
adb reboot recovery
# Make a Nandroid backup
# Mount manually /system and /sdcard from the "mounts | storage" menu of the Recovery
# Copy the content of /system/lib to the SDcard
Code:
adb shell
mkdir /sdcard/system
cp -r /system/lib /sdcard/system
# Clean /system/lib
Code:
rm -r /system/lib
# Recreate empty /system/lib and set permissions
Code:
mkdir /system/lib
chmod 755 /system/lib
# Unmount manually /system from the "mounts | storage" menu of the Recovery
# Mount manually /system_lib from the "mounts | storage" menu of the Recovery
# Copy the lib contents to /system/lib
Code:
cp -r /sdcard/system/lib/* /system_lib
# Set permissions to /system/lib
Code:
cd /system_lib
find . -type d -exec chmod 755 {} \;
find . -type f -exec chmod 644 {} \;

ln -s gralloc.msm8660.so gralloc.msm7x30.so
ln -s lights.msm8660.so lights.msm7x30.so
# Remove the SDcard /system/lib folder
Code:
rm -r /sdcard/system
exit
# Unmount manually /system_lib and /sdcard from the "mounts | storage" menu of the Recovery
# Reboot to bootloader
Code:
adb reboot bootloader
# Flash the boot.img and reboot
Code:
fastboot erase boot
fastboot flash boot XXX_lib_boot.img
fastboot reboot
Now you can use the tool above without concerns about free space
Enjoy!

Sorry, my fault! I thought this come after the 5 steps.

if a rom is zipaligned, doesn't this mean that there's no need being odexed - kind of same thing? (same performance, battery life...)
i've read that, but i'm no expert...

Zipaligning is about better RAM utilization. Odexing is about reducing the Dalvik VM which in theory should reduce CPU use and make the system run smoothly. You can watch the video, it is made by one of the Elite Recognized Developers of XDA so this guy probably knows what he is talking about. Moreover ALL Stock ROMs are odexed and I am sure that the companies developers are not just too lame to use it for nothing

Have you provided enough free space on your system partition? Try with a factory reset.
And once again:
If you are using this it is at your own will and risk

i think it was due to less space but still will try it once again after making space

Was a hard task to get enough space free.
Let's see how it works now.

Yes this may be an issue with the bigger ROMs. The easiest way is to move some app that you use rarely to /data/apps
The other way is to use the lib partition but this needs ramdisk modification and a hboot that supports it. It is not hard I may add a small how-to if more users want to use this tool

This would b great, I did it once for Fallout with one of your kernel ramdisks, but it was not so trivial and a pain in the a** doing this all by hand. Though it worked perfectly, I don't remember every step I did, and mayb I didn't do it the elegant way, as I'm not very experienced.
As far as I remember the complicated part was unpacking kernel+ramdisk, modifing ramdisk, repacking everything and signing it. But this has to be done only once (by one idividual) for every kernel (+ramdisk). The rest ist more or less flashing and copying from /system to /system/lib partition (can be done in recovery easily). The latter mayb realised with one single script installer for every kernel (and rom) I guess. But here I also lack the experince with script installers, elsewise I would have shared the info.
I did it on Windows with bootimg-tools via Cygwin (unpacking, repacking), with SignApk on cmd (signing), in recovery (flashing, copying). For flashing I guess fastboot is more elegant (reflashed whole rom with mod boot.img). For the rest I didn't found something more convinient, but maybe soemone can enlighten me.

HOW-TO move your /system/lib folder to the dedicated partition added to the first post. Tested and verified working. Just copy the commands carefully
Enjoy!

Thx, the new guide worked like a charm for me on Fallout v5.0.0 with your kernel v8.5. I think it is more or less what I did, when it worked for me before. Also the odexing stuff worked well. What I am just wondering about, as this is odexing Rosie, will this affect the Fallout Tweaks for Rosie? And I tended to use Titanium Backup to merge updated system apps (like Facebook) into rom (essentially moving to system I guess), are there any drawbacks doing it with odexed apps?

All apps will work the same way after odexing. I can confirm all Rosie tweaks in Fallout working.
As per the Titanium stuff I have no idea try it and let us know

when I am trying to copy /sdcard/system/lib to /system_lib it is showing not enough space....
Also in 4extrecovery - two system_lib are showing...
Any ideas?

Root Remix OS for PC

This guide is to root Remix OS for PC
You will need Ubuntu for Rooting (You can download and run it in live CD)
If you are experienced with linux systems don't read whats written in bracket
1. Download and Extract RemixRoot.zip
2. Copy system.img from your pendrive or hdd wherever you have installed Remix Os to this folder (ie RemixRoot folder it should be alongside Readme.txt)
3. Open Terminal (Ctrl+Alt+T)
4. Type
Code:
sudo -i
5. Enter your password (If you are running in live cd then no password)
6. Change directory to RootRemix folder (Goto tmp folder, right click and goto properties and copy location, this is your <dir> replace it in command below )
Code:
cd <dir>
7. If you did it right next line of terminal will end with RemixRoot# followed by blinking cursor
8. Now run rootx.sh script by typing
Code:
sh rootx.sh
9. If everything goes right there wont be any error message and you will get a root.img in your RemixRoot folder
10. Rename it to system.img and copy to your pendrive/hdd replacing previous system.img
11. Reboot and go to RemixOS and update SuperSU binaries
12. That's it! you are now rooted
Thanks to Chainfire & hackarchive

I tried it but i got no system.img, i got r/w access to system (choosen by install) so i tried to symlink it to my system directory and commented out all image mounted related things from script and then tried it.
but after that i cannot boot android anymore, i think the problem is app_process linking to daemonsu, since i set back to original it boots like normal but no superuser access. SuperSU said theres is no superuser installed.
Any suggestion?

Silly question but will I lose root access if I update to the newest version by flashing the new image over the top?

Yes a silly question.... Deserves a silly answer. It will still be underneath, but good luck trying to retrace it!

any other method for rooting, without using ubuntu?
#tested with ubuntu live, and it works like a charms. Thank you..

same problem here.

Hope same other method can solved

I modified the original script to work with the system folder installation and i removed all app_processX dependend things from script (dunno if it affects the root in any way, cannot find any issue by now) Read the Readme.txt for further installation instructions. The link you find on the reddit sub that GoPal has posted! I cannot post links right now.

You will get root.img file you will have to rename it to system.img

I've just installed RemixOS 2.0 onto a partition on my Lenovo X200T. I followed the instructions and all was good until I tried to run SuperSU. When it tried to update via the normal method the install failed and asked for a reboot. Any suggestions.

the answer is replace the system folder. this is my methode :
1. copy the system img from the extracted remix iso to somewhere
2. then run the script
3. unpack the system img that already rooted and copy all the content to the system folder of the remix (replace)
4. done. Remix os rooted.

Guys, I installed Remix to ext4 partition (in order to use all free space), so there's no "system.img" on it (but there's "system" folder). How to modify the script or to root Remix other way?
masdeco, thanks for the idea! How do you unpack img file, btw?

after root the system img then mount it, copy all the content to the system folder of your remix.
since I am a linux user so I use this command :
mount -o loop system.img tmp

this is so cool cool

Works Lenovo Yoga 2 11
Installed to a partition on my HD:
Downloaded RemixOS iso
extracted contents of iso
created temp, data and system folders
ran this tool to root the system.img (now root.img)
renamed root.img back to system.img
mounted system.img to temp folder
copied contents of temp folder to system folder
added entry in grub
now I am triple booting Windows, Linux and RemixOS 2.0 Android with ROOT
Thank You!!!

it shouldn't be too hard to figure out, put the files in your folder of choice with the system.img from your usb stick, run the batfile. it should create a file named rooted system image, now just replace system.img on your usb stick with that and run...
ofcourse I am assuming your system.img is identical to the one I had, which it should be if it was the 2.0 dev preview which is the only thing you can get today, right?
