How to avoid argument might be null

I am getting a warning Argument amountTarget might be null. Is there any way to ignore this warning?

            if (betid != null) {
            String betnumber = mData.get(i).get("betnumber");
            String amountTarget = mData.get(i).get("amountTarget");
            holder.tx_amount.setText(amountTarget);
            holder.tx_number.setText(betnumber);
            holder.checkBox.setChecked(true);

            //getting warning argument exception on amountTarget
            int x = Integer.parseInt(amountTarget) * amountX - deductAmount; 
            holder.tx_counter.setText(x);
        }

check that amountTarget isn't null by doing one of these:

if(amountTarget != null){
 int x = Integer.parseInt(amountTarget) * amountX - deductAmount;
}

or initialize the variable to something before using it, for example

amountTarget = 0
int x = Integer.parseInt(amountTarget) * amountX - deductAmount;

alternatively you could also do something like this 

if (amountTarget == null){
amountTarget = 0
}
