Question

I am trying to add a new event into the android calendar. Here is the code I am using

Intent intent = new Intent(Intent.ACTION_EDIT);
                    intent.setType("vnd.android.cursor.item/event");
                    intent.putExtra("title", event.getSummary());
                    intent.putExtra("description", event.getDescription());
                    intent.putExtra("eventLocation", event.getLocation());
                    intent.putExtra("dtstart", event.getStartDate());
                    if(event.getEndDate() == null)
                    {
                        intent.putExtra("allDay", true);
                    }
                    else
                    {
                        intent.putExtra("dtend", event.getEndDate());
                    }

                    startActivity(intent);

I am implementing this method in a separate class which is not an activity class. So I am extending the activity class here.

When i execute last line startActivity(intent); I am getting java nullpointer exception.

No idea how to proceed.

How could I add a entry in to android calendar?
Thanks

Answer 1

Are you instantiating your activity class with new? You can not do that. Activity classes must be instantiated by OS in order to be functional.

Solution:

You have to have a reference to Context in order to call context.startActivity(..). Pass an instance of context to your class in constructor. Hint: all Activities are Contexts, so just do new MyClass(this) from within an Activity.

Also, your class does not need to extend Activity.
