How can I fix this error?
I am developing extension for my app.
The extension I going to make is my own Component to Image
An annotation processor threw an uncaught exception.
[javac] Consult the following stack trace for details.
[javac] java.lang.IllegalArgumentException: Cannot convert Java type 'android.view.View' to Yail type
If possible so just share that part of code where is the error, so we can help you more. Here you’re trying to convert View to Yail type, this is not possible.
I think that the error you’re encountering is because Yail doesn’t recognize ‘android.view.View’ as a compatible type. Yail expects components to be in its own specific format.
@JEWEL is right. Could you check the part of your code where you’re attempting this conversion? It might help to look for a way to convert the View to a Yail type that can represent it, or to modify your approach so that a direct conversion isn’t necessary.
