I want to build an android application with maven. using this tutorial I create a xml file named pom.xml with this code:

I've got error:

what is this error for? and
how can I fix it?

Because your pom.xml isn't a Maven Project xml.
If you use IDE,notice the IDE notify,maybe it tell you what want to do.
Follow the hint,and do it.

Unknown packaging apk

I am trying to import an existing android application in eclipse. Eclipse is complaining about unknown packaging apk.
Maven 3.2.1 version. I tried different configurations under plugin xml tag but nothing works.
Below is my pom file:
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">

If the POM you're quoted above is complete, it looks as though you haven't added the android-maven-plugin to the pluginManagement section of your POM.
Something like this:
<pluginManagement>
<plugins>
<plugin>
<groupId>com.jayway.maven.plugins.android.generation2</groupId>
<artifactId>android-maven-plugin</artifactId>
<version>3.9.0-rc.2</version>
<extensions>true</extensions>
</plugin>
</plugins>
</pluginManagement>

A google search for unknown packaging apk turns up this blog. It appears that you need the following <dependency>:
<dependency>
<groupid>com.google.android</groupId>
<artifactid>android</artifactId>
<version>4.0.1.2</version>
<scope>provided</scope>
</dependency>

Not sure what exact solution is but i did below stuff and it worked:
1) Deleted maven repo and settings file and recreated new from scratch
2) I had maven plugin earlier but made changes to it as below.
<build>
<sourceDirectory>src</sourceDirectory>
<plugins>
<plugin>
<groupId>com.jayway.maven.plugins.android.generation2</groupId>
<artifactId>android-maven-plugin</artifactId>
<configuration>
<sdk>
<platform>19</platform>
</sdk>
</configuration>
</plugin>
</plugins>
</build>
3) mvn clean install from command line.

I am getting this error when adding pom.xml in apk.
I referred to this question Android with maven? Apk unknown
But mvn clean install doesn't help me...
So please help me to get rid of this error.
Thanks in advance.

Try moving those plugins, particularly the android-maven-plugin outside of <pluginManagement>. When specified inside <pluginManagement> they don't run so the android-maven-plugin extension isn't seen so maven doesn't know what to do with the "apk" packaging.

android-maven-plugin - How to set up apkMetaIncludes?

http://maven-android-plugin-m2site.googlecode.com/svn/apk-mojo.html#apkMetaIncludes
Pattern for additional META-INF resources to be packaged into the apk.
The APK builder filters these resources and doesn't include them into
the apk. This leads to bad behaviour of dependent libraries relying on
these resources, for instance service discovery doesn't work. By
specifying this pattern, the android plugin adds these resources to
the final apk. The pattern is relative to META-INF, i.e. one must use:
<apkMetaIncludes>
<metaInclude>services/**</metaInclude>
</apkMetaIncludes>
The META-INF folder is under src folder

<groupId>com.google.android</groupId>
<artifactId>android</artifactId>
<version>4.0.1.2</version>
<scope>provided</scope>
</dependency>
</dependencies>
</project>
At the end, my APK has no services folder!

This is actually wrong in the javadoc. I will fix it. In the meantime this should work
<configuration>
<apk>
<metaIncludes>
<metaInclude>services/**</metaInclude>
</metaIncludes>
</apk>
</configuration>
Of course I would also welcome feedback/confirmation that it works and potentially a pull request that updates the docs..

Error in pom file in Maven project after importing into Eclipse

I am actually new to the Maven framework. I already have a Maven project. I installed the Maven plugin etc into my EclipseIDE from http://m2eclipse.sonatype.org/sites/m2e. Then I imported my project and enabled dependencies, but the project is showing too many errors. The pom.xml itself is showing errors. The errors are
Project Build Error:unknown packaging:apk
Project Build Error:unresolvable build extension:plugin"
etc.
My error area is:
project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
<modelVersion>4.0.0</modelVersion>
<groupId>com.nbc.cnbc.android</groupId>
<artifactId>android.domain.tests</artifactId>
<version>1.0.0</version>
<packaging>apk</packaging>
<parent>
<groupId>com.nbc.cnbc.android</groupId>
<artifactId>android.domain.parent</artifactId>
<version>1.0.0</version>
<relativePath>../android.domain.parent/pom.xml</relativePath>
</parent>
<name>android.domain.tests</name>
<url>http://maven.apache.org</url>
Could it be because the url specified in the last line could be different?
Any ideas why this could be happening?
Any reply is highly appreciated. Thanks a lot in advance!!

You have installed the "normal" Maven plugin that works for Java projects (and .jar files).
For Android you need the Maven Android Plugin
Personally, I think that Android Maven is too much of a hassle for the few dependencies that I use in my projects, but this is how I set it up when I tried it out:
Set the ANDROID_HOME variable to your SDK root location and add the SDK's tools and platform-tools folders to your path (more info see this link)
Start Eclipse and enable "Dependency management" on your Android project.
Make sure you include Maven Central to you repositories and add the following to your pom (more info see this link or this link).
<dependency>
<groupId>com.google.android</groupId>
<artifactId>android</artifactId>
<version>2.3.3</version>
<scope>provided</scope>
</dependency>
<build>
<sourceDirectory>src</sourceDirectory>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<configuration>
<source>1.6</source>
<target>1.6</target>
</configuration>
</plugin>
<plugin>
<groupId>com.jayway.maven.plugins.android.generation2</groupId>
<artifactId>maven-android-plugin</artifactId>
<configuration>
<sdk>
<path>${env.ANDROID_HOME}</path>
<platform>10</platform>
</sdk>
<deleteConflictingFiles>true</deleteConflictingFiles>
</configuration>
<extensions>true</extensions>
</plugin>
</plugins>
</build>
Off course you can adjust the android version to your liking.

Last update: it seems that the name of the artifact is android-maven-plugin now: http://mvnrepository.com/artifact/com.jayway.maven.plugins.android.generation2/android-maven-plugin/3.6.0
So it should be like this:
<dependency>
<groupId>com.google.android</groupId>
<artifactId>android</artifactId>
<version>2.3.3</version>
<scope>provided</scope>
</dependency>
<build>
<sourceDirectory>src</sourceDirectory>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<configuration>
<source>1.6</source>
<target>1.6</target>
</configuration>
</plugin>
<plugin>
<groupId>com.jayway.maven.plugins.android.generation2</groupId>
<artifactId>android-maven-plugin</artifactId>
<configuration>
<sdk>
<path>${env.ANDROID_HOME}</path>
<platform>10</platform>
</sdk>
<deleteConflictingFiles>true</deleteConflictingFiles>
</configuration>
<extensions>true</extensions>
</plugin>
</plugins>
</build>
