Fatal Exception: java.lang.IndexOutOfBoundsException: Index: 4, Size: 1 at java.util.ArrayList.get(ArrayList.java:437) what does this mean, any fix for above issue.

Any help is appreciate!

hello @viji this means that you're trying to access the index 4 of an array or a list that only has 1 element inside, so before accessing an item inside an array or a list please check first if the index isn't greater than the array size with something like this

if( list.size() > index) {
    list.get(index)
}

or you can use a try catch block but that's not really solving the problem

You have to check your arraylist size first and check your data into console log it look you'r adding more data ( arrraylist.size< your data)
