Emulator question - G1 Android Development

How would I use the emulator provided in the sdk to test run a modified framework-res.apk ? I am not familiar with emulator use...I googled it a bit but didn't find anything specific to my question.

Use adb commands just like a real device. Failing that you can directly mount the system image file and modify it yourself.

How would I mount the image file and modify it? I tried the adb commands, pushing the file, and then I tried to reboot, or turn it off, and turn it back on but it wouldn't. So I closed it and started another emulator with no change.

The emulator is run off a system.img that is found in the SDK directory somewhere.
That's a yaffs3 file system that you can open with the appropriate program.

Blarg. I hate it when the forum marks something as read when you haven't actually read it. Anyway Koush is right. My sdk dev environment is Windows, and the path to the corresponding directory is
\android-sdk-windows-1.0_r2\tools\lib\images
However you probably want to be in Linux if you want to mount the yaffs2 filesystem.

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
under <sdk path>/tools
to list out your AVD(android virtual device)
android list targets

from here we choose our integer target, lets say 2
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 expand...
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]Set up Android SDK/ADB/Fastboot on Ubuntu Linux

When I first attempted to install the SDK, I found tutorials that only had bits and pieces about the whole procedure. A lot of Google searches and hours of eye strain. I wanted to write a solid tutorial, but instead of publishing it in a personal blog, I chose to publish it here on xda-developers. This is the definite forum to come to if you are interested in Android/G1/HTC Dream development or costumization. I wrote this to make the enlarge the knowledge of this community.
!! THIS TUTORIAL IS FOR THE LATEST UBUNTU RELEASE: JAUNTY JACKALOPE 9.04 !!
!!START -------------------------------------- Optional Preparation --------------------------------------
This applies if you -
Are interested in installing Ubuntu for the first time.
Are/will be reinstalling Ubuntu from scratch.
Want to keep your SDK installation easy to reach.
Want to keep things nice and clean.
And your machine -
Has a second hard drive.
Has free space for another small partition.
This procedure will make things easier during installation of the SDK and in the long run. Hopefully you've read about partitions. If you are dualbooting, please read this first to get an idea of what you're doing.
While installing Ubuntu and on the Prepare Disk Space screen (partition editor), select "Specify partitions manually (Advanced)"
On the Create Partition dialog, select the following options:
Type for the new partition: Primaryor Logical if you're dualbooting and know what you are doing.​
New partition size in megabytes: 5120MB (5GB) might work. BUT:
ccyrowski said:
It should be noted that if you ever plan on compiling kernels and/or cupcake ROM's you will NEED ubuntu8.04. You'll also need at least 10GB.
Click to expand...
Click to collapse
Location for the new partition: Beginning
Use as: Ext4 or Ext3Filesystem doesn't matter. (?)​
Mount point: /AndroidSDKEnter this manually​
Complete Ubuntu installation as usual.
-------------------------------------- Optional Preparation -------------------------------------- END!!​
You will now install the SDK.​
!!START -------------------------------------- Installing Android SDK --------------------------------------
Installing the SDK is the easiest of all.
Download the SDK.169.9 MB [http://developer.android.com/sdk/download.html?v=android-sdk-linux_x86-1.5_r3.zip]​
Right-click and select Extract Here.
Move the contents of the android-sdk-linux_x86-1.5_r3 directory to your desired location.If you followed Optional Installation, move the contents to your /AndroidSDK directory in the root of your filesystem.​
Close directory window.
-------------------------------------- Installing Android SDK -------------------------------------- END!!​
You will now set up your bashrc file and UDEV to recognize your HTC Device.​
!!START -------------------------------------- ADB + FASTBOOT --------------------------------------
The Android Debug Bridge (adb) is one of the tools that will help you the most when you run into flashing problems or running shell commands directly from your machine. UDEV will not recognize your G1 out of the box, but we will configure it with some rules so it can connect.
We will work with /AndroidSDK as the location of your sdk. If this is not your setup, I think you're smart enough to figure it out.
Editing .bashrc file to use tools from /AndroidSDK/tools/ directory -
Go to your home folder.Example: /home/wddglr/​
Press Control + H to view hidden files.
Look for your .bashrc file and double click to open it with gedit.
Add the following lines to the top of the file:
Code:
#AndroidDev PATH
export PATH=${PATH}:/AndroidSDK/tools
IMPORTANT NOTE
savethechicken said:
This is the way that I have my .bashrc file setup. For those having problems with it not recognizing the adb as a command try this...
Code:
export PATH=$PATH:/AndroidSDK/tools
I removed the {} around ${PATH} and it is working if I had them on it would say that it didn't recognize the command. Removed them and all works well.
Click to expand...
Click to collapse
Setting up UDEV to recognize HTC Device -
Type the following into a terminal (Applications > Accessories > Terminal):
Code:
gksudo gedit /etc/udev/rules.d/51-android.rules
Now add the following line to the blank file:
Code:
SUBSYSTEM=="usb", SYSFS{idVendor}=="0bb4", MODE="0666"
Click save and close.
To restart udev, open up a terminal and enter:
Code:
sudo /etc/init.d/udev restart
Setting up fastboot -
Download this fastboot binary from http://android-dls.com.130.4 KB [http://android-dls.com/files/linux/fastboot]​
Once downloaded to your desktop, right click and select Properties.
Navigate to the Permissions tab and configure the following option:Execute: [√] Allow executing file as program​
Click Close.
Move the fastboot bianary to your /AndroidSDK/tools/ directory.
Reboot.
-------------------------------------- ADB + FASTBOOT -------------------------------------- END!!​Now you can use adb and fastboot directly from any terminal. If you chose to do the Optional Preparation, you can now save your Eclipse Workspace and your downloaded/custom ROMs/Themes in this new /AndroidSDK directory keeping things easier to reach and safe from evil disk errors or other mishaps!!! :O​If you are having problems, send me a PM. I will be happy to help.
*applaudes* awesome. Should be added to helpful threads.
very nice! perhaps add a "(How-To)" prefix to thread??
Everything was going great in setting this up until I got to this part "gedit /etc/udev/rules.d/51-android.rules"
I cannot find "51-android.rules" inside of "rules.d"
Any thoughts>?

it does not exist, you will make it.

I was just thinking earlier about doing this same "How-To" guide, I was surprise to see it posted just now.
Anyways, great job!
Can someone sticky this thread. Now I have ADB & fastboot on my Win7, Ubuntu, and OS X Partition. Thank you wddglr.
bravo...linux rocks even better now!...
Awesome tutorial for setting this up. Have been using adb/sdk on ubuntu since oct. but this would have saved me some headaches back in the first couple of weeks.
The onlything that is not clear and/or confuses me is
Setting up the udev to recognize the device.
SUBSYSTEM=="usb", SYSFS{idVendor}=="0bb4", MODE="0666"
Have never used this (will now to see if it will do anything) and the only problem i have is that sometimes i have to kill-server to get it to connect correctly but i have seen this happen to almost everyone on many forums since the 9.04 came out. And even after putting this file on the computer i have had the problem.

It happens to me also from time to time. especially when i reboot and want to go into adb while the device is rebooting. although that file, 51-adndroid.rules, is what helped me get adb to recognize the device. the guide on developer.android.com talked about 50-android.rules but after a few deep searches i found this: http://groups.google.com/group/android-developers/browse_thread/thread/1d3488c601243686
Okay A few questions for you....
First I fixed the whole "couldnt find the (51-android.rules) file now I am having issues with executing ADB!
When in terminal this is what I get...
"[email protected]:/home/nick# /AndroidSDK/tools/adb
bash: /AndroidSDK/tools/adb: cannot execute binary file
[email protected]:/home/nick#"
and I also noticed something different from when I start terminal the first lines now state
"bash: : command not found
[email protected]:~$"
I dont remember the first line ever being there, but I could be mistaken!
Any help would be greatly appreciated!
Edit: You state creating "Mount point: /AndroidSDK" During Installation, and what I did was Just place my AndroidSDK at root so it is at "/AndroidSDK". I dont know if this makes a difference.
I am actually running ubuntu 8.10 ha! I just tried to update But I keep getting errors! is there anything I can change to get this to work on ubuntu 8.10?

okay, a few things -
seems like your .bashrc file isn't setup right (?)
make sure that the two lines you inserted into it are on separate line
Code:
#AndroidDev PATH
export PATH=${PATH}:/AndroidSDK/tools
because maybe export PATH=${PATH}:/AndroidSDK/tools got commented on accident if you copy pasted.
When copying your SDK to the root of your filesystem, did you copy it as your own user or as root? you can use:
Code:
gksu nautilus
to copy system files with complete root privileges.
What exactly are you trying to update, Ubuntu or ... ? There shouldn't be a difference to get this working on 8.10, the only thing that seemed to change was the 51-android.rules file. Maybe this can help -
renaming it to 50-android.rules with
Code:
gksu nautilus
and deleting any backups (use CTRL+H to view hidden files).
restarting udev using:
Code:
sudo /etc/init.d/udev restart
Remember this is for 9.04, not 8.10. I hope this helps.

[email protected]:~$ su
Password:
[email protected]:/home/nick# mv /home/nick/Desktop/AndroidSDK /

And I went to the bashrc file and it is entered in there correctly.
This is still what I get even after restarting Udev...
" bash: : command not found

bash: /AndroidSDK/tools/adb: cannot execute binary file

# ~/.bashrc: executed by bash(1) for non-login shells.
# see /usr/share/doc/bash/examples/startup-files (in the package bash-doc)
# for examples
Okay your .bashrc is setup right and it's recognizing adb and its directory.
I would say it's something to do with permissions. since you moved it under su, you are not the owner so i would say that you'd have to change the permissions of /AndroidSDK
you can do that with -
Code:
gksu nautilus
Navigate to /
Right click on /AndroidSDK and select Properties
Click on Permissions tab
Select your user account as the owner
hopefully now it will function correctly

Partitioning HD
First off, thank you for this thread, it's most excellent. I have a question that is slightly off topic, but not so much. I have Ubuntu 9.04 installed on my recovery partition. This partition is only 10 GB, while I have Vista on my main. I have almost 100 GB free on my main drive, and what I want to know is, if I resized my partitions to give more space to Ubuntu, how would it affect my comp? (if at all). And which OS should I be on while resizing, Ubuntu or Vista?

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!

::::EDIT:::::
if you did have success making an AVD or know where i can find some premade profiles for the HTC Magic/Dream lmk
:::EDIT2::::
i just gotta finish downloading my JDK and i can get it to boot
does anyone know how to compile a system.img from just my /system folder or in essence can the /system folder just be booted without having to compile it into system.img format?

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

I tried before, but emulator freezes when I try to reboot it. I think can install Cyanogenmod and the CMUpdater and use my own update.zip to do the update, but I think it will not work.

it doesnt work you have to nandroid the update.zip
i was up till like 4 am last night trying to compile a tattoo build and i kept getting stuck on flash at my update script where it CHMOD CHOWN system:xbin
toooo tired to care to mess with it anymore...
tried everything to get the emulator to boot my custom rom but no go
tried doing it like
emulator -sysdir c:\c\herosysimage\ -avd hero
and like
emulator -system C:\c\herosysimage\system.img -avd hero
no boot
also tried putting system.img in the avd folder

An easier way. (installing adb / fastboot / revolutionary in linux)

I've looked at all the other threads detailing how to get adb, fastboot, revolutionary, nbimg, and other applications set up on linux and there's a much easier way than typing all those commands, and editing rules files and changing permissions...
It requires little to no knowledge of linux, you only have to type one line into the terminal, and it takes about 1 minute. (seriously, time it!) Ready?
Go!
download and open file attached to this post
open terminal
type : sudo nautilus
enter your password
once nautilus opens, click on file system(on left side)
drag and drop adb (or fastboot, or revolutionary, or nbimg, or any other executable) to the folder called "bin"
close nautilus
close downloaded file
congratulations you've just installed adb the easy way.
you can now use it in the terminal without the need to add ./ before the command or the need to be root or the need to do any of those complicated things you didn't understand from any of the other tutorials.
====
Since I can already see the question coming :
How do I update? simple...
follow the previous procedure exactly the same except paste the new version of whatever into the bin folder and replace the older version. It really is that easy.
Why not do it the way the other tutorials say?
The bin folder isn't going anywhere and requires root privileges to modify so it's hard to screw it up.
If you marked the application as executable and added the path to the file in some other directory (like most other tutorials tell you to do) you may have issues if you ever modify or delete or screw up the directory where you installed it one of the other ways...
How does this work??
The bin folder houses binaries/applications that the system needs to function. By putting the files in that folder, you are telling the system that these binaries are executable, that they are safe(don't require root) and that they can be used system wide in any directory.
Speaking of root, Why don't I need root any more?
Because you put them in the bin folder, and not the sbin folder.
If you would like to require root privileges to use the included tools, follow the instructions but instead of dragging the files into the bin folder, drag them into the sbin folder.

Hope this helps someone somewhere.
Note to moderators : feel free to move this to development, if you feel that's where it ought to be...

[Q]How can I extra the system.img file

Can dev teach me ..

You will need the android SDK and adb.
You can either do this through the terminal app on the phone or by using adb...
With adb:
From windows command line, and the phone connected via usb.
adb shell
su
cat /dev/block/system > /sdcard/system.img
If you use the terminal, you run the same commands as above, except the adb command.
To get the file on your hard drive, run this from the windows command prompt:
adb pull /sdcard/system.img .

EDIT- lol, Jim and I had two different perspectives on your question . Are you asking how to create a system.img based off of your current /system, or are you asking how to extract an .img you already have and set up a working directory for ROM building?
Under Win7? Good luck with that. The system.img contains a filesystem that Windows doesn't natively support. You can use an app like Ext2Read to open and extract .img's, but if you do that all the symlinking will get messed up because Windows filesystems don't support symlinks. Also, Ext2Read might freeze or not fully extract the image just because of compatibility issues.
I highly recommend you use VirtualBox or set up a dual-boot with a Linux OS like Ubuntu. From there, you can install the ROM Kitchen which makes building ROMs a lot easier. It will let you set up a working directory based off of a system .img, and it detects all symlinks and adds them to the updater-script.

Thanks cogeary .
I need the ext2read to explorer the *.img file and it can extra anyone file from *.img to my disk.
And can I use the *.apk from other *.img to create/use on my phone/system.

Sometimes. You can probably use apps like the alarm clock or browser that come from a different firmware, but don't try using framework files (like framework-res, systemui, etc) and important apps (like the dialer or phone) from different firmwares.
