Assuming the last Java code posted is accurate, it looks like you forgot a closing curly brace for the onCreate method, so the rest of your code is considered to be a part of that function body (which is wrong).

Also, you'll probably get a compiler warning or error on that method because you annotated it @Override but there isn't a onCreate method in AndroidNonvisibleComponent or its supers. You could move some of that logic into the constructor, and most of it isn't needed since it's inflating a view layout, which you can't do in a component.

If you're not using any code editor, then use it, it will correct your mistakes in code!

newbiedeveloper · September 18, 2020, 5:50am

okay now i am using notepad ++

Techno_Vedang · September 20, 2020, 7:18am

Ide is better

vknow360 · September 20, 2020, 7:31am

Notepad++ is a text IDE and not a Java IDE.

newbiedeveloper · September 27, 2020, 9:29am

Okay, eclipse IDE is good or not ??

Kumaraswamy · September 27, 2020, 9:38am

Don't go much off-topic please
