[javac] java.lang.IllegalArgumentException: Cannot convert Java type 'AndroidViewComponent' to Yail type

AyProductions · January 4, 2024, 11:36am

I was making an extension, everything worked out fine, but......
This error comes only, and no other error comes:

error: cannot find symbol
[javac] public void HighlightText(String regexPattern, int color, AndroidViewComponent component){
[javac] ^

I am trying to getView of textView from AndroidViewComponent
but, the error above is shown while compiling.

I searched a lot, but couldn't find something that worked here...
Why this error is coming? Any ideas?

Have you import AndroidViewComponent?

And where are you compiling your extension? Tempelate? or Rush?

AyProductions · January 4, 2024, 11:43am

I imported android.view.View; only........
I searched the internet and not fully sure how to import AndroidViewComponent....

is it like this?

import android.view.ViewComponent

(i could be very wrong)
If wrong, please tell me how do I import viewComponent.

I am using Niotron IDE to compile my extension

Kevinkun · January 4, 2024, 11:48am

You'd better to use some powerful IDE for coding, like Android Studio, VSCODE, Eclipse

AyProductions · January 4, 2024, 11:49am

I will change my IDE soon,
but how to fix that issue?

Kevinkun · January 4, 2024, 11:53am

import com.google.appinventor.components.runtime.AndroidViewComponent;

Kumaraswamy · January 4, 2024, 11:53am

Would be helpful if you show the full relevant code.

Kevinkun · January 4, 2024, 11:55am

And your IDE may be not support use AndroidViewComponent as the type of parameter, try Component instead.

AyProductions · January 4, 2024, 12:15pm

I have fixed the androidViewComponent issue
thank you kevinkun
