A way to calculate the time taken by a part of source code (very simple and rarely useful but... I was tired of writing these lines every time).

Clean SQLite database, if it grows much
Long working apps have DB that grows and grows. It must be controlled, when records qty is very big, and most old data should be deleted

Choose audio file and play with MediaPlayer
Although the use case (see title) sounds trivial, it took some time to get the result. The search returned many hits on the topic, from which the last valid "Single Point of Truth" could be found. The obstacles were the read permission and the path provided by the ContentChooser. Thanks to Erel''s "GetPathFromContentResult()" the path format expected by the MediaPlayer could be determined.

Taking SquareRoot in SQL
SQLite doesn''t have SQTR as a standard function, so you would normally do this in code. There is a way though to do this in SQL with a CTE.

WebView and Particle.JS
Ever wondering my B4A app has nice looking background with animation, to be honest - i know nothing about live wallpaper nor how to create bitmap animation using canvas. I ever saw in the net, a page using nice animation called Particle.JS. It''s javascript code to generate the wonderful animation. So i made simple login page which use WebView as animation background.

File Explorer [source code]
What distinguishes this from other explorers is that the upper beam (â back) it is not controlled as the other elements of the list (it always remains in place), always available and in view.

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.
