Taskhelper
Taskhelper is a dynamic Android application that allows for "wizard" style applications to be defined using JSON and synced with the device in the form of a ToDo list. There is also a server side component that handles the synchronisation and data storage.
Building
The project uses Maven to build things, and takes the form of a multi module maven project.
Development was done using Eclipse, and guidelines found here: http://www.workreloaded.com/2011/09/android-build-automation/ were followed to get Eclipse, ADT and maven playing nicely together.
Releasing
In order to package the apk for release, you need to configure a few things
First, create your key following the instructions at http://developer.android.com/guide/publishing/app-signing.html#cert
Then create a profile like this
<settings>
<profiles>
<profile>
<activation>
<activeByDefault>true</activeByDefault>
</activation>
<properties>
<sign.keystore>/absolute/path/to/your.keystore</sign.keystore>
<sign.alias>youralias</sign.alias>
<sign.keypass>keypass</sign.keypass>
<sign.storepass>storepass</sign.storepass>
</properties>
</profile>
</profiles>
</settings>
in your settings.xml file in ~/.m2
Once this is done, you can create a production version of the apk with the following command:
mvn clean install -P release
which will in turn sign and zipalign the apk.
