Use "android update" on cmd line to create a new project from existing code

In the documentation here
https://developer.android.com/tools/projects/projects-cmdline.html
it says that
'android update'
can be used to create a new project from existing code. The example however does not state how to do exactly that.
Given an existing project folder (basically containing a template android project), how do I create a new project with its own folder from cmd line?

Lennert, really i think 'android update' poor. I wanted copy an existing project, but renaming the package name, but i couldn't be able to do that, then I did that using script ant.

Ant Build Failed

I am trying to build an Android Project using Apache Ant through Command Line but it is giving me Build Failed with the following error statements:
Java.io.IOException: Cannot run Program. "..\android_sdk\platform-tools\aapt.exe"
D:\MediaSync\build.xml:429: Execute failed: java.io.IOException: Cannot run program "..\android_sdk\platform-tools\aapt.exe"
I am new to this thing so i am not getting any idea how to get over this error. Searched alot about it but still scratching my head..
Anybody any idea about it then please tell me.
EDIT: Here are parts of my Buil.xml file
<!-- General SDK location -->
<property name="sdk-folder" value="D:/sdk" />
<!-- Preset tools location -->
<property name="android-platform-tools" value="${sdk-folder}/platform-tools"/>

Make sure aapt.exe is installed at the correct path relative to your build.xml file (../android_sdk/platform-tools). That path is likely relative to your project, but not the build.xml.

I encountered the same problem on a 64-bit fedora platform and finally worked it out following this: http://blog.mx17.net/2012/10/25/android-on-ubuntu-ioexception-on-aapt/
It had failed because of trying to run a 32-bit program on an 64-bit architecture.
Maybe this would help.

Your error message says:
D:\MediaSync\build.xml:429: Execute failed: java.io.IOException: Cannot run program "..\android_sdk\platform-tools\aapt.exe"
while your aapt.exe is located in:
C:\android-sdk-windows\sdk\platform-tools\aapt.exe\
Obviously the build.xml tries to search D:\ for android_sdk\platform-tools\aapt.exe, which is the wrong path.
There should be a property for you to specify the path of aapt.exe, or it reads from system's PATH varibles.
To get a solution, post the lines around line 429 in build.xml. In line 429, there should be a <exec> task, be sure to include the whole content of that task (copy from <exec ...> to </exec>).

There is a bug in the intellij android studio and perhaps other IDEs that points to platform-tools for some executables/libs that now live in build-toos. A workaround for now is to make sim-links fof the necessary files.
So on linux/mac
platform-tools$ ln -s ../build-tools/android-version-blah/bin/appt appt
and
platform-tools$ ln -s ../build-tools/android-version-blah/lib lib
for Windows, install LinkExtensions and replace ln with mklink and read the help from typing mklink with no args. In Windows, the file would be appt.exe

A quick fix you can do is copy the aapt.exe and lib folder from the build-tools to the platform-tools folder.

Android built apk with ant

I want to compile a cm9 theme using ant so I have this code given in the sample theme :
<?xml version="1.0" encoding="UTF-8"?>
<project name="TemplateTheme" default="help">
<!-- ADD YOUR ANDROID SDK PATH TO THIS FILE -->
<loadproperties srcFile="local.properties" />
<!-- The ant.properties file can be created by you. It is only edited by the
'android' tool to add properties to it.
This is the place to change some Ant specific build properties.
Here are some properties you may want to change/update:
source.dir
The name of the source directory. Default is 'src'.
out.dir
The name of the output directory. Default is 'bin'.
For other overridable properties, look at the beginning of the rules
files in the SDK, at tools/ant/build.xml
Properties related to the SDK location or the project target should
be updated using the 'android' tool with the 'update' action.
This file is an integral part of the build system for your
application and should be checked into Version Control Systems.
-->
<property file="ant.properties" />
<!-- DON'T TOUCH THIS ONE -->
<loadproperties srcFile="default.properties" />
<!-- ADD YOUR KEYSTORE PROPERTIES HERE -->
<loadproperties srcFile="key.properties" />
<!-- quick check on sdk.dir -->
<fail
message="sdk.dir is missing. Make sure to generate local.properties using 'android update project'"
unless="sdk.dir"
/>
<!-- Import the actual build file.
To customize existing targets, there are two options:
- Customize only one target:
- copy/paste the target into this file, *before* the
<import> task.
- customize it to your needs.
- Customize the whole content of build.xml
- copy/paste the content of the rules files (minus the top node)
into this file, replacing the <import> task.
- customize to your needs.

in order to avoid having your file be overridden by tools such as "android update project"

prepare-resources" is a shell script, not an executable. To be able to execute it, install cygwin, a UNIX-like environment that includes lots of software including shells capable of executing the script.

Hudson Android multi-configuration test project can't find test results - "No test report files were found. Configuration error?"

I have android test project that i've integrated into the Hudson. I have created a free-style software project with next settings :
1. Source Code Management - custom workspace
2. Run an Android emulator during build :
* Android OS Version: 4.0.3
* Screen density: 240
* Screen resolution: WVGA
* Device locale: en_US
* SD card size: 16M
3. Invoke Ant:
Target: all clean emma debug install test
Build File: workspace/Project/build.xml
4. Post-build Actions
* Archive the artifacts: **/*test-TEST.xml
* Publish JUnit test result report: **/*test-TEST.xml
* Record Emma coverage report: **/coverage.xml
* Record fingerprints of files to track usage: **/*test-TEST.xml
Here's build.xml file part that covers my ant target:
<!-- version-tag: custom -->
<target name="test" depends="-test-project-check"

<property name="tested.project.absolute.dir" location="${tested.project.dir}" />

<xpath input="${tested.project.absolute.dir}/AndroidManifest.xml"

<xpath input="AndroidManifest.xml"

<property name="emma.dump.file"
value="/data/data/${tested.manifest.package}/coverage.ec" />
<if condition="${emma.enabled}">
<then>

</exec>
</target>
<import file="${sdk.dir}/tools/ant/build.xml" />
</project>
Now, this project works fine and i get both emma coverage and test results, but when i configured multi-configuration project with the same options, except for android emulator i set different variables with os, density and screen resolution, i got stuck with one error -

For emma coverage i had to change path in Hudson into /Users/biercoff/Work/Workspace/HarnessExternalTest/coverage/coverage.xml to make it work,
but when i tried to do the same thing for Junit test results, Hudson refused to "see" it. File is in the project folder under junit-results folder, but everytime i run new build, i get the same No test report files were found. Configuration error? error message. Tried many variations, but no luck. I'm missing probably something really tiny. Could somebody help me, please?

Hudson searches for jUnit test results relative to its workspace. And you can't specify an absolute path (I've been using Hudson/Jenkins for more than a year and still not sure why not). So in your case it is looking only at things that are deeper in the directory level than the workspace. Now, for a multi-congiguration project the workspace does not start at the top level, but deeper - it includes axes names (e.g.: workspace_root/AXIS1_NAME/AXIS1_VAL...). But your tests are located up the directory tree from that workspace. You have to copy them in a build step into ${WORKSPACE} and then Hudson will be able to publish them.

How to pass arguments to aapt when building android apk?

I'm building an apk using ant on Linux (not using Eclipse), and I'm trying to find an easy way to switch between compressing assets and not, in order to keep my huge database uncompressed for < 2.3. As per this article:
http://ponystyle.com/blog/2010/03/26/dealing-with-asset-compression-in-android-apps/
I see that it's possible to do this by specifying something like aapt -0 db, but I can't find information on how to edit the way ant interacts with aapt. Or do I have to run aapt by itself? What do I do?

It's Android's build.xml (you'll find this under your SDK, tools and ant) that executes AAPT when building.
Find your build.xml and replace the "-package-resources" target with the target below. I'm pretty sure (not able to test it at the moment) you'd be able to swith compression on and off with either "-Dcompression.disabled=set" when build with ANT or "compression.disabled=set" in your .properties-file.
