Android Class Diagram UML

Question

I'm trying to create a class diagram for an android project. I want my classes represent the activities, services and interfaces that I will implement.

There are several questions about it on the web, but I couldn't find a definitive answer.

I know that there aren't specific rules for Android and UML, but I have some doubts.

• How can I represent the relationship between an Activity and a AsyncTask ?
• How can I indicate that an Activity has an intent to another Activity ?

Maybe if someone has an example, will really help.

Answer 1

Maybe something like this?

• MyBackgroundTask IS A AsyncTask
• MyActivity IS A Activity
• MyActivity HAS ONE MyBackgroundTask

You can use a dependency to show that there is an relationship between the AnActivity class and the AnotherActivity class:

In this case, it means that the AnActivity class requires the AnotherActivity class for its specification or implementation. Also, use notes to make it clear.

Update:

Another example:

• MainActivity IS A FragmentActivity
• MainActivity HAS SOME fragments. The fragments are of type String.
