Question

I want to add calendar events programmatically (directly) in android 4+. Is it this possible to be tested on emulator? I don\'t own an android phone. Some sample code wou

Answer 1

Here is the way to ask user to which calendar the event has to be added. As my requirement was this and didn't find the solution at one place. I have summarized and came up with this solution, hope it helps someone :)

final ContentResolver cr = this.getContentResolver();
        Cursor cursor ;
        if (Integer.parseInt(Build.VERSION.SDK) >= 8 )
            cursor = cr.query(Uri.parse("content://com.android.calendar/calendars"), new String[]{ "_id", "calendar_displayName" }, null, null, null);
        else
            cursor = cr.query(Uri.parse("content://calendar/calendars"), new String[]{ "_id", "displayname" }, null, null, null);
        if (cursor != null && cursor.moveToFirst() ) {
            final String[] calNames = new String[cursor.getCount()];
            final int[] calIds = new int[cursor.getCount()];
            for (int i = 0; i < calNames.length; i++) {
                calIds[i] = cursor.getInt(0);
                calNames[i] = cursor.getString(1);
                cursor.moveToNext();
            }

            SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
            final long startDate = sdf.parse(slotData.getSlot_date() + " " + slotData.getSlot_from()).getTime();
            final long endDate = sdf.parse(slotData.getSlot_date() + " " + slotData.getSlot_to()).getTime();

            AlertDialog.Builder builder = new AlertDialog.Builder(this);
            builder.setTitle("Select any one");
            builder.setSingleChoiceItems(calNames, -1, new DialogInterface.OnClickListener() {

                @Override
                public void onClick(DialogInterface dialog, int which) {
                    ContentValues cv = new ContentValues();
                    cv.put("calendar_id", calIds[which]);
                    cv.put("title", title);
                    cv.put("dtstart", startDate);
                    cv.put("hasAlarm", 1);
                    cv.put("dtend", endDate);
                    cv.put("eventTimezone", TimeZone.getDefault().getID());

                    Uri newEvent ;
                    if (Integer.parseInt(Build.VERSION.SDK) >= 8 )
                        newEvent = cr.insert(Uri.parse("content://com.android.calendar/events"), cv);
                    else
                        newEvent = cr.insert(Uri.parse("content://calendar/events"), cv);

                    if (newEvent != null) {
                        long id = Long.parseLong( newEvent.getLastPathSegment() );
                        ContentValues values = new ContentValues();
                        values.put( "event_id", id );
                        values.put( "method", 1 );
                        values.put( "minutes", 15 ); // 15 minutes
                        if (Integer.parseInt(Build.VERSION.SDK) >= 8 )
                            cr.insert( Uri.parse( "content://com.android.calendar/reminders" ), values );
                        else
                            cr.insert( Uri.parse( "content://calendar/reminders" ), values );

                    }
                    dialog.cancel();
                }

            });

            builder.create().show();
        }
        if (cursor != null) {
            cursor.close();
        }
