ContentResolver delete multiple

I know a record can be deleted like this:

getContentResolver().delete(Events.CONTENT_URI, Events._ID + " =? ", eventId);

where eventId is a String array containing, in this case an event's ID. In my case, I don't want to delete one event, but multiple. So I've got an array of eventIds containing multiple eventIds. I could of course loop through the array and delete the events one by one, but is it also possible to delete them using just one call?

Try this code, 

ArrayList<ContentProviderOperation> operationList = new ArrayList<ContentProviderOperation>();
ContentProviderOperation contentProviderOperation;

for (/*loop over your arrayList*/) 
{
    contentProviderOperation = ContentProviderOperation.newDelete(Events.CONTENT_URI).withSelection(Events._ID + " =? ", new String[]{yourId}).build();
    operationList.add(contentProviderOperation);
}

try {
    getContentResolver().applyBatch(Contract.AUTHORITY, operationList);
} 
// catch the exceptions
