build emulator for Windows

http://android.git.kernel.org/?p=platform/development.git;a=blob_plain;f=tools/eclipse/README_WINDOWS.txt;hb=HEAD

[RM 20080623] 1- To build the Eclipse plugin: Under Linux: $ cd your-device-directory $ tools/eclipse/scripts/build_server.sh destination-directory This will create an "android-eclipse.zip" in the selected destination directory. Then in Eclipse, you can use Help > Software Updates > Find and Install > Search for new Features > Next > New Archived Site > select the new android-eclipse.zip. Then with the new archive checked, click Finish/Next. 2- To build a Windows SDK, you need two steps: a- First you need to create a Linux SDK: Under Linux: $ cd your-device-directory $ make sdk Note: if you get an error when building the javadoc, make sure you use a Java SDK 1.5 Note: if you get an error when building layoutlib, make sure you use a Java SDK 1.5.0-b13. b- Once you have a Linux SDK, you can create a Windows SDK: You need a Windows machine with XP or Vista and Cygwin. - Installer at http://sources.redhat.com/cygwin/ - Set Default Text File Type to DOS/text, not Unix/binary. - Select packages autoconf, gcc, g++, bison, python, zip, unzip, mingw-zlib - Suggested extra packages: emacs, wget, openssh, rsync Then under Cygwin: $ cd your-device-directory $ tools/buildbot/_make_windows_sdk.sh path-to-the-linux-sdk.zip destination-directory

To build the SDK for Windows, look at this: 
http://android.git.kernel.org/?p=platform/development.git;a=blob_plai... 

It's a bit old but step #2 is still "mostly" valid except you MUST 
make sure cygwin is in binary/unix mode and not text/dos mode. Also 
the main script moved: 

make_windows_sdk.sh moved to [platform/development.git] / build / 
tools / make_windows_sdk.sh 
http://android.git.kernel.org/?p=platform/development.git;a=blob;f=bu... 

Unless you are actually changing the tools, quite frankly just get the 
prebuilt ones, it's much easier.
