What is the advantage of this kind of designing?

Hi, I just learned AI2 few months ago. I don't understand why the project, ex. 'copy_1', name will be different from the app name, 'copy' only. I have to modify the app name every time. What is the advantage of this kind of designing? Thanks!

The actual App Name is different from the AppName property. Two of your projects can have the same AppName property but not the same name. As for what's the advantage(s), I'm not really sure there are none, it's just probably there to avoid repetition, especially since App Inventor is based on Java.

Hello, there is one thing what is to say, package name or project name under that there is a app name, which is what the name of app which will be there when we install a app from APK or from play store. APK name is what the name of project and the app name is what will be shown when the app is installed.

Here are some useful links,

Copy project with another name

Hello. I want to copy an existing project to build an other one with some minor differences. but when i copy existing project and change the copy name, after compil it' the same package name so it delete my other project... is there a way to built a new project from an old one with an other name ?

What is the package name of App build using AppInventor how to know the package name

appinventor.ai_email.appName Example: [grafik]

App name in Google Play

Check in your Screen1.properties for AppName - here the name you used to open the project is used. If you called your project "myapp" then it will be there and come through to the compiled apk as the App Name. You can change what is in AppName to whatever you want....

Correct me, if interpreted incorrectly. Thanks

Thanks for your kindly reply!

I know project and app could have different name. But I couldn't understand why ai2 would allow there is different name of project and app.

I think if you want your app has a name of you like, you should name the project after it at the begin, not modify the app name in the latter. There is different name of them, in the future you maybe need to repair or update your app, then you could be not easy to find where the original project is, unless you set a system to find it. So I don't know what is the advantage of this kind of designing?

By the way, I have a project named notifier, for example. Then I save this project as a new project named slider. You would find that the name of AppName in the properties of slider is notifier.

Only when you copy a Project will App Inventor present an increment in the Project Name. This is to safe guard against the calamity of having two Projects of the same name. What you should be doing is exporting your Project to your PC Drive (often) as a Backup - thus keeping the same Project name throughout your development cycle. This is obviously safer than relying on the MIT Servers but the Project Name increment is there for those students that do not have any other means of backup.
