Adding an event to ContactsContract.CommonDataKinds.Event in Android via contact picker

Questions

In an activity of my Android application, I would like to open the content picker. And when the user selects one of those contacts, there should be a new entry (an event with type "other") that is inserted into the table ContactsContract.CommonDataKinds.Event .

Starting the contact picker intent is easy. But then one must get some data for the selected contact and create a new entry in the event table. This is the code I have so far, unfortunately it doesn t work:

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    if (resultCode == RESULT_OK) {  
        switch (requestCode) {  
            case CONTACT_PICKER_ID:  
            Uri contactData = data.getData();
            //String contactID = contactData.getLastPathSegment();
            // ADD A NEW BIRTHDAY FOR THE SELECTED CONTACT START
            ContentValues values = new ContentValues();
            values.put(ContactsContract.Data.MIMETYPE, ContactsContract.CommonDataKinds.Event.CONTENT_ITEM_TYPE);
            values.put(ContactsContract.CommonDataKinds.Event.TYPE, ContactsContract.CommonDataKinds.Event.TYPE_OTHER);
            values.put(ContactsContract.CommonDataKinds.Event.CONTACT_ID, 250);
            values.put(ContactsContract.CommonDataKinds.Event.START_DATE, "2012-12-12");
            Uri dataUri = getContentResolver().insert(ContactsContract.Data.CONTENT_URI, values);
            // ADD A NEW BIRTHDAY FOR THE SELECTED CONTACT END
            break;
        }
    }
}

This code requires the permission "WRITE_CONTACTS".

The contact ID "250" is hard-coded. Of course, it should be retrieved from the intent data that is sent along with the contact picker s result.

The code above terminates with a NullPointerException. Why is this so? And how do I get the contact s id from the intent so that I can use it for inserting the new row?

  Edit:    Additionally, the line ...

getContentResolver().insert(ContactsContract.Data.CONTENT_URI, values);

... throws an exception. What s wrong there?

Answers

Here s how to do it, assuming this is how you called the contact picker:

int CONTACT_PICKER_ID = 1001; //some arbitrary number that you choose
Intent intent = new Intent(Intent.ACTION_PICK, ContactsContract.Contacts.CONTENT_URI);
startActivity(intent, CONTACT_PICKER_ID);

The data.getData() call returns a lookup key that you have to query the contacts DB for to find the contact s ID.

if (resultCode == RESULT_OK) {  
    switch (requestCode) {  
        case CONTACT_PICKER_ID:  
            Cursor cursor =  managedQuery(data.getData(), null, null, null, null);
            cursor.moveToFirst();
            //get the contact s ID
            contactId = Cursor.getLong(cursor.getColumnIndexOrThrow(ContactsContract.Contacts._ID));

...

The contactId contains the ID you want.
