RSA Encrypt and Decrypt [B4X]
I build a auth method for my app to protect my API and one of this step is to signed requests to the api to ensure that every request comes from my app. RSA is the best method for that, because this is not a hash, so that the same input is ever the same output. The API knows the Private Key, the apps knows the public key.

easy and fast list choices [B4X] [XUI]
I needed some easy and multiplatform access to option choices. This small lib, based on XUI Views (B4XDialog and B4XListTemplate) seems to work. You have to define a object like ''dlg'' once and than you can ask the user for choices in just one line.

Change the OK-Cancel buttons order in B4XDialog [B4X] [XUI]
OK-Cancel or Cancel-OK, what to prefer in dialogs? It depends on the guidelines and it should be flexible. That''s why I did this small modification in the B4XDialog library and I hope, that something like that could be integrated in the official one.

Tip - Modified server response [B4X]
The app sends a request to a server implemented with B4J. The server responds with a number. The user internet provider modified the server response and returned a JavaScript that does something (it is related to "safe internet" feature). Bottom line is that even if you are calling your own web service you cannot assume that the server response will not be modified...

AS BottomMenu [B4X] [XUI]

So I decided to build a class that I just need to add one view in the designer with less work. ;) -You have many options to customize the menu. -easy to use -compatible with B4A,B4I and B4J -you can hide the middle Button -4 Tabs or 2 Tabs

RSS Viewer using xCustomListView [B4X]
After having used the RSS Viewer library in the past, and now finding that it won''t function with my secure sites, I decided to start with Erel''s XUI CustomListView example and then integrate that with using the XML2MAP library to write a RSS viewer. The attached example is for B4A, but it would probably be easy enough to adapt to b4i as well.

HSV Colour bar [B4X] [XUI]
I have taken Erel''s HSV Colour Picker https://www.b4x.com/android/forum/threads/b4x-xui-hsv-color-picker.91058/ and converted it into a bar as his picker was too large for my app. It is really a Hue picker. You can have either horizontal or vertical orientation.
