How to use emulator image?

[wonkim]

Hi,
After successful build from Ubuntu. How can I use emulator image to
test my own build?

Thanks.

1,download emulator tools.

2,copy builded new image to toos/lib/images

3,start emulator

If you've sourced build/envsetup.sh you can just type emulator at the
command line to start it up.

For me, this didn't work. Did it work for others?

On the other end, copying the images to tools/lib/images does work with the
emulator in Android SDK. But the Maps application "is not installed" and so
doesn't launch. Is there other things that need to be copied?

Thanks,

Mike

If you checked out the Android source tree with repo, make will build
the emulator for you and put it into .../out/host/linux-x86/bin/emulator
(or whatever architecture you use). Now, you will have to set the
environment variable ANDROID_PRODUCT_OUT to the path to you *.img files.
This is normally .../out/target/product/generic. So basically this looks
like this:

$ export \ ANDROID_PRODUCT_OUT=/path/to/mydroid/out/target/product/generic
$ /path/to/mydroid/out/host/linux-x86/bin/emulator

This will start the freshly built emulator.

I hope this helps.

It works. Thanks.

[Mikael Bourges-Sevenier]

Well, the emulator starts indeed but many apps don't work:
- no Maps application
- no internet access

Is something missing in the code or is there some special settings to enable
internet access and Maps?

1. Map isn't in the source code tree.
2. I think your problem is no name resolving or say no DNS.
It seems that the libc.so in the system.img refuses to
provide DNS lookup. We replaced the libc.so with the one
came with binary SDK release then the problem is gone.
I didn't dig into the source yet.

I have encountered the same problem "unknown host".
One question, what tool can I used to edit the system image.

many thanks!

I don't know if there is any convenient tool that you can use to edit
YAFFS2 image.
What we did are:
1. get libc.so from
http://dl.google.com/android/android-sdk-linux_x86-1.0_r1.zip
(mksdcard sdcard.img; emulator -sdcard sdcard.img; adb shell;
cat /system/lib/libc.so > /sdcard/lib.cso;
mount -o loop sdcard.img somewherer; you got the libc.so)
2. rm out/target/product/generic/system.img
3. put the libc.so you got in step 1 into out/target/product/generic/
system/lib
4. type make than you have new out/target/product/generic/system.img
that will
resolve domain name

After sourcing 'build/envsetup.sh', I ran 'setpaths'..

Now checking my env variables:

ANDROID_PRODUCT_OUT=/opt/workspace/android.git.kernel.org/platform/out/
target/product/sooner
OUT=/opt/workspace/android.git.kernel.org/platform/out/target/product/
sooner

Notice the 'sooner' at the end. Its an error, and the path set by
envsetup.sh is wrong. The real path is '/opt/workspace/
android.git.kernel.org/platform/out/target/product/generic'

Where is this 'sooner' coming from? Anyone have similar issues?

Looks like 'partner_setup' will setup the variables correctly.

Now I try to source it from bashrc.. and this is the error:

Usage: partner_setup <product-name>
Defaulting to product "generic"
Couldn't locate the top of the tree. Try setting TOP.
ANDROID_PRODUCT_OUT:
ANDROID_BUILD_TOP:

Hi,

This is due to a default setting in build/core/envsetup.mk
file for the variable "TARGET_PRODUCT". By default this is configured
to "sooner" and can be overridden either by modifying the
build/buildspec.mk or exporting the environment variable
"TARGET_PRODUCT" to your choice (ex: generic).

Another approach may be to use "partner_setup" command.

Warm Regards,
Anil

[Muthu Ramadoss]

Anil,

Thanks. Got it.

And looks like you got to be in 'your.source.root.directory' to carry
out the commands.

In my case, after 'cd /opt/workspace/android.git.kernel.org/
platform'.. everything works fine.

Here's the correct output:

Usage: partner_setup <product-name>
Defaulting to product "generic"

ANDROID_PRODUCT_OUT: /opt/workspace/android.git.kernel.org/platform/
out/target/product/generic
ANDROID_BUILD_TOP: /opt/workspace/android.git.kernel.org/platform

all right, two quick solutions without modifying source tree
1. 'make sdk' instead of simple 'make'
2. if you have done 'make' before,
'rm out/target/product/generic/obj/PACKAGING/
systemimage_unopt_intermediate/system.img',
'rm out/target/product/generic/system.img', 'make sdk', then you
got it

Freedom,

Thanks.

We honestly need a developers guide. Does it exist somewhere?

Hi,
Yes it does. Check development/pdk/docs (platform
development kit). However the info is slightly obsolete as most of the
paths mentioned in the documents are missing in source checkout.

Warm Regards,
Anil

[Muthu Ramadoss]

Ha, there it is! Thanks Anil.

Hopefully the docs gets updated often.
