    <p>You should test, if an instance for this event exists. See the <a href="https://developer.android.com/reference/android/provider/CalendarContract.Instances.html" rel="noreferrer">documentation of the Android's CalendarContract.Instances class</a>.</p> <p>Especially the <a href="https://developer.android.com/reference/android/provider/CalendarContract.Instances.html#query%28android.content.ContentResolver,%20java.lang.String%5B%5D,%20long,%20long,%20java.lang.String%29" rel="noreferrer">second query method</a> should be helpful in this case.</p> <p>This examples is some code, I posted on my <a href="http://www.grokkingandroid.com/androids-calendarcontract-provider/" rel="noreferrer">blog post about the CalendarContract provider</a> - slightly altered for your needs:</p> <pre class="lang-java prettyprint-override"><code>long begin = // starting time in milliseconds long end = // ending time in milliseconds String[] proj = new String[]{ Instances._ID, Instances.BEGIN, Instances.END, Instances.EVENT_ID}; Cursor cursor = Instances.query(getContentResolver(), proj, begin, end, "\"Your event title\""); if (cursor.getCount() &gt; 0) { // deal with conflict } </code></pre> <p>Be aware: The time is always in UTC millis since the epoch. So you might have to adjust given the user's timezone.</p> <p>And the last parameter should contain the title of the event you have added to the calendar. Keep the quotes - otherwise Android looks for "your" or "event" or "title"!</p> <p>And do not forget to include the necessary permissions.</p>

    1. COThank you very much. Just the thing I am looking for. However.. the query returns 0 if I include the event title. The first query in the documentation(without the search term) works perfectly. Can you help me out?

    2. COI ended up using the first query to retrieve all the events between start time and end time, and comparing the event titles using an if condition.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
