My code:- https://res.cloudinary.com/df3qkgfyp/raw/upload/v1630038577/FGrid_t6pegp.java
Error:-
Did you try anything from yourself?
Oh wait...do you know what null object means?
Null means nothing empty
So what do you think is empty/not initialized in your code?
you did not provide your context variable the context from componentcontainer
and another thing you are trying to use imageresource which is not possible so i prefer you to use bitmap or drawable instead
