B4ASnippetDatabase [OR LIST OR ARRAY ETC.]

Group and count Recordset [or list or array etc.]

Needed a fast way to take a recordset and group and count a specified column, so that is get the unique items of that column and count the occurrences of all those unique items. A recordset with a column with largish (10 to 2000 chars) and about 400000 rows produces a map with 60000 values and counts in about 700 milli-seconds.

AndroidX SDK

Android Support Library was implemented and maintained in the last 8 years by Google. It includes a wide range of features and it hides many of the differences between the various Android versions. Android Support Library was replaced by AndroidX SDK. It is no longer maintained and new versions of Firebase SDK depend on AndroidX. This is a good time to switch to AndroidX.
