Question

Cannot read records after inserting to google calendar.

Some time letter, records are read.

Why?

If take Context from Activity, then everything works fine. If Context from AndroidTestCase or take on their Application, it does not work.

Note: Calendar with id=calendarId is empty.

public static void test(final Context context, final int calendarId) {
    // insert
    java.util.Calendar calendar = java.util.Calendar.getInstance();

    ContentValues contentValues = new ContentValues();

    contentValues.put("calendar_id", calendarId);
    contentValues.put("dtstart", calendar.getTime().getTime());
    contentValues.put("dtend", calendar.getTime().getTime() + 1L*60*60*1000);
    contentValues.put("title", "test_title");

    Uri uri = Uri.parse("content://com.android.calendar/events");
    context.getContentResolver.insert(uri, contentValues);

    // read
    Uri.Builder builder = Uri.parse("content://com.android.calendar/instances/when").buildUpon();
    ContentUris.appendId(builder, Long.MIN_VALUE);
    ContentUris.appendId(builder, Long.MAX_VALUE);

    Cursor cursor = context.getContentResolver.query(
        builder.build(),
        new String[]  { "event_id", "title" },
        "Calendars._id=" + calendarId,
        null,
        null);
    try {
        if (!cursor.moveToNext()) {
            // fail
            throw new IllegalStateException();
        }
    } finally {
        cursor.close();
    }
}

My mistake. In code:

Uri.Builder builder = Uri.parse("content://com.android.calendar/instances/when").buildUpon();
ContentUris.appendId(builder, Long.MIN_VALUE);
ContentUris.appendId(builder, Long.MAX_VALUE);

Can not set start date Long.MIN_VALUE value.
