Import .ics-file into google calendar on android device

Question

I've got an android application which manages and display event like data out of a local SQLite database.

I would like to offer my customers the option to convert the data from the database to an .ics-file and import that file into a calendar.

I know how to create and store a valid .ics-file out of my database.

My problem is to import that file into the google or any other calendar. I don't want to create a custom local calendar, I simply want to "open" the ics-file so that the user can choose a calendar or let the data import directly.

User Interaction -> .ics-file creation -> import of all events into the calendar

Any advice? Is this even possible?

Answer 1

You can check out the import service of Google Calendar API. It will require the calendarId which is explained on the Getting Started page.

The request body will contain the file you want to attach (though its limited to Google Drive, so you may want to look into Drive API as well)

The Events resource attachments field description

attachments[] list File attachments for the event. Currently only Google Drive attachments are supported. In order to modify attachments the supportsAttachments request parameter should be set to true.

There can be at most 25 attachments per event,

I had the same problem a few weeks ago. I found how to export individual tasks or events to Google Calendar. Check whole information here

I quote the way to add a event to the calendar from the link above:

To add an entry to a specific calendar, we need to configure a calendar entry to insert using the ContentValues as follows:

ContentValues event = new ContentValues();

Each event needs to be tied to a specific Calendar, so the first thing you're going to want to set is the identifier of the Calendar to insert this event into:

event.put("calendar_id", calId);

We then set some of the basic information about the event, including String fields such as the event title, description and location.

event.put("title", "Event Title");
event.put("description", "Event Desc");
event.put("eventLocation", "Event Location");

There are a number of different options for configuring the time and date of an event.

We can set the event start and end information as follows:

long startTime = START_TIME_MS;
long endTime = END_TIME_MS;
event.put("dtstart", startTime);
event.put("dtend", endTime);

If we are adding a birthday or holiday, we would set the entry to be an all day event:

event.put("allDay", 1);   // 0 for false, 1 for true

This information is sufficient for most entries. However, there are a number of other useful calendar entry attributes.

For example, you can set the event status to tentative (0), confirmed (1) or canceled (2):

event.put("eventStatus", 1);

You can control who can see this event by setting its visibility to default (0), confidential (1), private (2), or public (3):

event.put("visibility", 0);

You can control whether an event consumes time (can have schedule conflicts) on the calendar by setting its transparency to opaque (0) or transparent (1).

event.put("transparency", 0);

You can control whether an event triggers a reminder alarm as follows:

event.put("hasAlarm", 1); // 0 for false, 1 for true

Once the calendar event is configured correctly, we're ready to use the ContentResolver to insert the new calendar entry into the appropriate Uri for calendar events:

   Uri eventsUri = Uri.parse("content://calendar/events");   Uri url =
 getContentResolver().insert(eventsUri, event); 

The call to the insert() method contacts the Calendar content provider and attempts to insert the entry into the appropriate user Calendar. If you navigate to the Calendar application and launch it, you should see your calendar entry in the appropriate Calendar. Since the Calendar syncs, you will also see the Calendar entry online, if you're using the Google Calendar on the web.
