Activity tutorial

The tutorial explains step by step how to create the Hello World activity bundle.

Create the bundle directory structure:

mkdir HelloWorldActivity.activity
mkdir HelloWorldActivity.activity/activity

Write the activity.info file, to describe your bundle in the activity sub-directory (i.e. HelloWorldActivity.activity/activity/activity.info). The Activity Bundles specification explain in detail the meaning of each field.

[Activity]
name = HelloWorld
service_name = com.ywwg.HelloWorldActivity
class = HelloWorldActivity.HelloWorldActivity
icon = activity-helloworld
activity_version = 1
show_launcher = yes

Design an icon for your activity, according to the icon format and place it in the activity sub-directory. The file name should match the one specified in the info "activity-helloworld.svg".
