Hi.
I know very little Java, so I don’t claim to be developing useful extensions.
I’m having fun trying to understand .aix extensions.
I wrote these 20 lines, compiled with Rush, imported the extension into Kodular, and everything works!
package com.digitalmatik.Test1;
import com.google.appinventor.components.annotations.SimpleFunction;
import com.google.appinventor.components.runtime.AndroidNonvisibleComponent;
import com.google.appinventor.components.runtime.ComponentContainer;
import java.util.regex.Matcher;
import java.util.regex.Pattern;
import android.util.Patterns;
import java.util.Random;
public class Test1 extends AndroidNonvisibleComponent {
public Test1(ComponentContainer container) {
super(container.$form());
}
@SimpleFunction(description = "Returns left characters")
public String SubStrLeft(String text, int nchar)
{
if (text == null || nchar <= 0 || text.isEmpty()) {
return "";
}
if (nchar >= text.length()) {
return text;
}
return text.substring(0, nchar);
}
}I change the extension, for example, the last line in return “xxxxx”;, compile, import into kodular again, but the result remains the same.
I tried clearing the browser cache (I use Brave and Edge): the result remains unchanged.
I also tried increasing the ‘Version’ value in rush.yml, but the result remains unchanged.
I close the browser, reopen kodular, test, and it works!
Where or what am I doing wrong?
Thanks
Henry
