Hello, I'm new to extension building, so forgive my noob question.
I started today and decided to make a very simple extension --- Add Two Numbers
I used editor.appybuilder.com to build my extension. This is the code...
/** ~~~~~
* Created with the AppyBuilder Code Editor.
* This is a template for basic Extension.
* Modify this template to customize your extension.
*
* **** NOTE: DO NOT use a package name.
* **** The package name will be created for you automatically.
* **** Adding a package name will cause a compile error
*/
import android.content.Context;
import android.util.Log;
import com.google.appinventor.components.annotations.*;
import com.google.appinventor.components.runtime.*;
import com.google.appinventor.components.common.ComponentCategory;
@DesignerComponent(version = 1, description = "This Extension was created with the AppyBuilder Code Editor.<br>" +
"Create your own here:<br><a href='https://editor.appybuilder.com' target='_blank'>https://editor.appybuilder.com</a><br>",
category = ComponentCategory.EXTENSION,
nonVisible = true, iconName = "http://appyBuilder.com/extensions/icons/extension.png")
@SimpleObject(external = true)
public class Fffff extends AndroidNonvisibleComponent {
private ComponentContainer container;
/**
* @param container container, component will be placed in
*/
public Fffff(ComponentContainer container) {
super(container.$form());
this.container = container;
}
@SimpleFunction(description = "Adds 2 numbers and returns sum")
public Object AddTogether(final Integer num1, final Integer num2) {
int sum = num1 + num2;
return sum;
}
}And this is the build error
