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).

Orientation and accelerometer. The attached program displays the values of the different sensors: It creates a PhoneSensors object for each type of sensor. As you can see in the attached code, two Maps are used to hold the phone sensors and the other required data. This way there is no need to write any duplicate code.

B4ATutorialB4A [TIP]
Reset the manifest editor code to the default code [Tip]
Use case: you downloaded an old example and you want to reset the manifest editor code so it will have the correct targetSdkVersion and theme. Open the manifest editor, delete all text and save it. Open the manifest editor code again and the default text will appear.

Retrieving 2 JSON data feeds from an online server - Shared module with B4i
Here is a simple to follow B4i tutorial on how to retrieve JSON data from an online server, in this case I''m using a well known Coronavirus COVID-19 data feed. The project layout file can easily be copied and pasted into a B4A layout file, you can also place the code module into a shared folder as B4i and B4A both use the exact same shared code module.
