FontAwesome To Bitmap
Unlike an older "TextToBitmap" sub that you can find in the forum, this code vertically centers the icon. It can also be used in B4J and B4i (only need to change the font line).

HTML-Standalone QR-code generator for websites
Sometimes you need a QR-code generator in your website (which is working together with B4x). I searched for a standalone creator which is easy to handle. I came to this site: QR-code generator. I uses Javascript to generate the QR-code. I''ve modified the example (removed all inputfields and replaced them with simple variables).

Resize Bitmap with a maximum Byte limit
Sometimes the images we use in our Apps are overly large. In some cases, images are entered by the user and therefore we do not know the size. And to manage them we need them to fall within a certain Byte limit. How to reduce them within the limit? Here is a code that allows you to redimension the images while maintaining the proportion and returning within the Byte mitie that serves us

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.
