How to Generate Class Diagram (UML) on Android Studio?

UML (Unified Modeling Language) is the general-purpose modeling language used to visualize the system. It is a graphical language that is standard to the software industry for specifying, visualizing, constructing, and documenting the artifacts of the software systems, as well as for business modeling.

UML Class Diagrams are the main building blocks of every object-oriented method. The class diagram can be used to show the classes, relationships, interface, association, and collaboration. UML is standardized in class diagrams. Since classes are the building block of an application that is based on OOPs, so as the class diagram has an appropriate structure to represent the classes, inheritance, relationships, and everything that OOPs have in their context. It describes various kinds of objects and the static relationship between them.

When working with diagrams, utilize the diagram editor’s context menu to accomplish various activities. You can see class members, add new ones, remove old ones, see implementations, check parent classes, conduct basic refactoring, add notes, and so on. If you want to include a class UML in your Android Project then follow the below steps mentioned in this article to get going…

Method #1: Adding the Stock Extension to Studio

Android Studio has a great plugin that can help you get crisp UML diagrams directly in your Android Project and manage that too in in-studio itself! Adding it is simple, and great, just follow the steps below!

Figure 1. Adding the Visual Paradigm SDE.

And the UML is generated in just a matter of seconds!

Method #2: The Instant Reverse Method

Ever played UNO? Well, this method is similar to reverse card, you create a UML first and then import it simply to Android Studio and add it to your project

1. Open the Visual Paradigm program.
2. Make a whole new project.
3. Select Instant Reverse…from the drop-down menu with Java language from the Tools bar above that says Code (or other)
4. Add your project to the project by selecting the application folder where it is stored (i have selected the complete folder application)
5. The application should now display in the Class Repository’s left pane.
6. Then simply right-click the project you’ve created and choose Reverse to the new class diagram from the context menu.

Figure 2. Creating the Project in Visual Paradigm First

Select whether you want the packages included in the class diagram or only the project’s class diagram to appear on your screen, and then adjust it as needed.

Method #3: The easy way out

Just like the title of this method speaks for itself, creating UML this way is demandingly easy, you just need to be having Visual Paradigm installed in your Android Studio Path, and then just follow the below steps:

1. Open the Visual Paradigm program.
2. Right Click anywhere and tap “Create UML for Android”
3. And you’re done just like that, just export the created UML and then import the same in your Android Studio Project

Figure 3. The easiest way out there.

Method #4: Not able to see the plugins

If you are not able to see the online marketplace which is mentioned above in step #1 then, this is a workaround, you need to download the plugin to your system offline, then simply install it by the methods given below

Those who wish to utilize simpleUML with Android Studio but are having trouble getting it to run.

• Now, follow the instructions outlined below.
• Go to File Settings (File Settings) by clicking on File.
• From the Left Panel, select Plugins and then Install the plugin from the disc.

Figure 4. Opening Plugins

• Locate and pick the SimpleUML jar file.
• Restart Android Studio (File/Invalidate Caches/Restart/Just Restart) now.
• Right-click the Package name and choose New Diagram or Add to simpleUML Diagram New Diagram after restarting.

Method #5 For the Developers out there using Kotlin

Well, this article even backs you up if you are using Kotlin and although this Kotlin state machine library does not connect with Android Studio, it is simple to visualize state machine structure on the PlantUML website.

So these were all the methods that would get you to achieve creating the UML in your Android Studio’s Project and get your project flow going!

Android studio uml generator

Execution flows in the applications sometimes can be difficult to visualize without having UML diagrams. In particular sequence diagrams allows to capture the flow logic of a program, logic methods, usage program, and logic of services. This type of diagrams can be represented using UML notation and in order to export this diagram some programs like Enterprise Architect use the XMI specification. The goals of this project are to automatically generate sequence diagrams based on the usage of the application, and also link the high­level GUI events into the low­level method calls.

In order to accomplish this, we have one module that functions as an Xposed module.

When our Xposed module detects that a package has loaded, it checks our SharedPrefs file to see if it should listen to that package. If so, it hooks into that package’s context, binding a service to it that will listen when the package itself has loaded, when a class has been constructed, and when a method has been called using the Messenger interface.

Currently, our service takes that data and then writes it to a XML file in XMI format.

Our future plan is to implement the XMI-UML conversion itself. We envision that, when the user wants the corresponding XML diagram, our application sends that file up to a server, which will convert it to UML then send it back down to the application. The application will then allow the user to easily transmit this UML diagram either by email or another service, like Dropbox.

Xposed — An application that can hook methods, and do certain things before, or after the method is used. Useful for being able to track when a method is used Lombok — Simplifies the interaction between models and the classes that use them by generating getters/ setters dynamically. Dagger — A dependency-injection framework, useful in Android for following the Singleton pattern correctly ButterKnife — An easier way to bind views from XML to code by using annotations RxJava — For asynchronous method calls, useful for loading work off the main thread SimpleXML — Writes model objects to XML files Retrofit — Simplifies the interaction between server and application

Note, because our project at this point is rather well established, we didn’t want to add directories to further confuse the structure. Those we have added an artifacts tag for issues. Here we will tag things that should be in artifacts

How to generate Class Diagram (UML) on Android Studio

Posted by: admin November 24, 2017 Leave a comment

I’ve try to search and found this link, but Ctrl + Alt + Shift + D doesn’t work.

I also use find Action Ctrl + Shift + A to find action about diagram and uml but found nothing.

I also search for the uml plugin,
but most of them didn’t work with new version of intelliJ (I didn’t try it I just read the comment).

I found a free pluggin that can generate class diagrams with android studio.
It’s called SimpleUML.

Update Android Studio 2.2+:
To install the plugin, follow steps in this answer: https://stackoverflow.com/a/36823007/1245894

Older version of Android Studio
On Mac: go to Android Studio -> Preferences -> Plugins

On Windows: go to Android Studio -> File -> Settings -> Plugins

Click on Browse repositories. and search for SimpleUMLCE
(CE means Community Edition, this is what android studio is based on).

Install it, restart, then you can do a right click on the folder containing the classes you want to visualize, and select Add to simpleUML Diagram .

That’s it, you have you fancy class diagram generated from your code!

For those who want to use simpleUML in Android Studio and having issues in running SimpleUML.

Now follow the below steps.

Step 1:

Click on File and goto Setting ( File -> Setting )

Step 2

Select Plugin from Left Panel and click Install Plugin from Disk

Step 3:

Locate the SimpleUML jar file and select it.

Step 4:

Now Restart the Android Studio

Step 5:

After you restart Right Click the Package name and Select New Diagram

Step 6:

Set a file name and create UML file. I created with name NewDiagram

Step 7:

Now Right Click the Package name and Select the file you created. In my case it was NewDiagram

Step 8:

All files are stacked on top of one another. You can just drag and drop them and set a hierarchy.

Like this below, you can drag these classes

I have managed to to do it in a way. Perform all the steps as referenced by Michal Rowicki above.

1. Open Visual Paradigm software.
2. Create a new Project
3. There would be an option on the Tools bar above that states Code
   and select Instant Reverse. from the drop down menu with Java
   language(or other)
4. Select your application folder where your project is located and
   add it to the project(i have selected the complete folder
   application)
5. The application should now appear on the left pane in Class
   Repository
6. Then all you do is right click the project that you have added and
   select Reverse to new class diagram
7. Select either you wish to have the packages included in the class
   diagram or just the class diagram of the project

Then it should appear on your screen and customize it as you wish

However i do not know if the plugin in Android Studio was necessary nevertheless it has worked in a way for me.

1. type Ctrl + Alt + S (or go to Preferences)
2. go to the Plugins tab, press “Browse repositories” button
3. search:
   Visual Paradigm SDE for IntellIJ (Community edition) Modelling Case Tool
4. install it.

You need to install proper software. Now it should works well.

I guess that UML Class Diagram is only available on Ultimate Edition.

To show UML diagram click right mouse button on specific class -> Diagrams -> Show diagram…
Or you can in editor click Ctrl + Alt + Shift + U .
You could append new classes to diagram by drag and drop. On the top of window you could choose more options. To save UML you should just click on save icon.

Update 24.3.2016

Good to know – it is possible to integrate VP into Android studio (in my case 1.5.1) now. Do not forget to backup your Android Studio settings (you can find them in Users%userName/.AndroidStudioX.X on Windows) ahead of installation.

I was trying to make it work, but created vp project did not contain any diagrams. Maybe someone else will have more luck.

I was using this manual http://www.visual-paradigm.com/support/documents/vpuserguide/2381/2385/66578_creatingauml.html to make Visual Paradigm working in Android studio, but action in 2. did not invoke dialogue in 3. So I Have asked Visual Paradigm support for help and they replied that Android Studio integration is not supported right now.

Reply from Visual paradigm reply from Apr 17 2015:

Thank you for your inquiry and I’m very sorry that at the moment we
only support integrate with the standard IntelliJ IDEA, but
not integrate with the Android Studio. We may consider to support it in our future release, and I’ll keep you post once there
any update on this topics. Feel free to contact me for any questions
and wish you have a good day!

This post was deleted, so I will try to make it more clear.

As such I am considering previous answers as misleading and not useful. Therefore I thing that it is important for others to know that, before they lose their time trying to make it working.

There is Code Iris which you can install by going to File -> Settings -> Plugins -> Browse Repositories, then find and choose Code Iris.
Restart then you will have a new Code Iris tab.

Solution:

1. Run Visual Paradigm
2. Do as below, pointing to Android Atudio
   directory on step 4

1. Open Android Studio and right click on project

I’m developing with android studio 2+.

to create class diagrams I did the following:
– install “ObjectAid UML Explorer” as plugin for eclipse(in my case luna with android sdk but works with younger versions as well)
… go to eclipse marketplace and search for “ObjectAid UML Explorer”.
it’s further down in the search results.
after installation and restart of eclipse …

open an empty android or what-ever-java-project in eclipse.
then right click on the empty eclipse project in the project explorer
-> select ‘build path’
then I link my ANDROID STUDIO SRC PATH into my eclipse android project.
doesn’t matter if there are errors.
again right click on the eclipse-android project and select: New
in the filter type ‘class’
then you should see among others an option ‘class diagram’
… select it and confgure it … png stuff, visibility, etc.
drag/drop your ANDROID STUDIO project classes into the open diagram -> voila рџ™‚

I open eclipse(luna, but that doesn’t matter).
I got the “ObjectAid UML Explorer”
that installed I open an empty android project oin eclipse, right

You can use the simple program StarUML. The trial version is unlimited and can do almost anything.

Onced installed you can use it to generate great number of uml digrams just by pasting the source code. Class diagram is just one type of it. (It understands not only Java language but C#, C++ and other)
