I’m gonna try making an extension with no skills and some of googles help and see where I get my 1,00 errors worth of time :joy:, I’m unzipping appinventor-sources now.

Edit: I have successfully built my extension however added no blocks or properties, I wanted to test to see if it worked and now I’m on my way.

Template

Template.java (3.8 KB)

This will give you all blocks which can be used in Kodular and any other AI for an extension in case you can’t find it anywhere else. IT WILL THROW YOU AROUND! Also includes:

- Properties
- Defining variables
- Context is included in definition
- Some others

You’re not supposed to build it, it’s an example… Create a new extension and just use those examples to create your blocks and use Android documentation to get your code. You are also meant to go into the AppInventor folder and CMD not the first AppInventorSources folder to build.

Oh Sorry, I did not compile the Template.java file

I did this and Build Failed

You’re supposed to do ant extension not ant.

Send me your Java file and I’ll take a look. If you trust me.

Can this be made into a Extension?

I’m not a magician. So I have no idea. The one thing I know can be included is the permission it needs :joy:

Do you think I know everything in this world? Let me know so I can respond with the correct answer…

Neither do I, I gave you a template to start with… Use this.

@DesignerComponent(version = 0,
                   description = "",
                   category = ComponentCategory.EXTENSION,
                   nonVisible = true,
                   iconName = "websiteToIcon")
@SimpleObject(external = true)
@UsesPermissions(permissionNames = "android.permission.READ_PHONE_STATE, android.permission.READ_PHONE_NUMBERS") // For example
public class ExtensionName extends AndroidNonvisibleComponent implements Component {
