I am trying to show the same MainActivity on clicking a RecyclerView item (to load another list).
But when addNextIntentWithParentStack is executed, application freezes and not responding for infinite time. Can anybody tell me the issue with this code?
I am using TaskStackBuilder for enabling Back Stack.

itemView.setOnClickListener(new View.OnClickListener(){
                @Override
                public void onClick(View view)  {
                    Context context =  view.getContext();
                    Intent startIntent = new Intent(context, MainActivity.class);
                    TaskStackBuilder stackBuilder = TaskStackBuilder.create(context);
                    stackBuilder.addNextIntentWithParentStack(startIntent);
                    PendingIntent pendingIntent = stackBuilder.getPendingIntent(0,PendingIntent.FLAG_UPDATE_CURRENT);

                }
            });

What I have tried:

I tried adding below code instead of addNextIntentWithParentStack. But, still same issue. When I remove addParentStack, It works but not as expected. The issue caused by when I add parent.

stackBuilder.addParentStack(MainActivity.class);
stackBuilder.addNextIntent(startIntent);
