I am currently working on an emergency app that dials service short codes or numbers when a user clicks on a card.
So far, i have been able to achieve the dialing feature but i want to start a new activity from one of the cards instead of dialing a number.
I tried using an intent to start the new activity from the OnClick Method but my app crashes while other cards works perfectly well
Below is the error message generated by the IDE and the CardviewDataAdapter.java code.
CardViewDataAdapter.java Code:
public class CardViewDataAdapter extends RecyclerView.Adapter<CardViewDataAdapter.ViewHolder> {
private List<ItemObject> itemList;
public CardViewDataAdapter(Context context, List<ItemObject> itemList) {
this.itemList = itemList;
}

@Override
public CardViewDataAdapter.ViewHolder onCreateViewHolder(ViewGroup parent,
int viewType) {
// create a new view
View itemLayoutView = LayoutInflater.from(parent.getContext()).inflate(
R.layout.cardview_row, null);
//Todo: set the view's size, margins, paddings and layout parameters
// create ViewHolder
ViewHolder viewHolder = new ViewHolder(itemLayoutView);
return viewHolder;
}
// Replace the contents of a view (invoked by the layout manager)
@Override
public void onBindViewHolder(ViewHolder viewHolder, int position) {
