    The attached projects wraps this. The project depends on files in the Objects/res/values folder of the B4A project. Therefore use this B4A project as your base if you want to make use of it. The library files (JAR & XML) are in the /Files folder of the attached project. Copy them to your additional library folder.

    The B4A project also makes use of CustomViews. You therefore need to set the CustomType of the CustomView to IndeterminateProgressView once you have selected/enabled library IndeterminateProgressView in your B4A project and added additional/new CustomView views.

    Circles spin CW and then ACW. You can define as many colors as you want for each circle.

    Enjoy!

    (Thanks @DonManfred)

    Edit: See project with new library files in post #2

    An update. New library files (JAR and XML) are in the /files folder of the B4A project. Copy them to / replace them in your additional libraries folder. Addition adds the following:
    1. Set the spinning duration of each circle individually
    2. Set ReverseAnimation to True or False:
    If True then the spinning direction will reverse
    If False then the spinning direction will continue in a CW direction (but the spinning circle will spin, come to a halt, and then continue in the CW direction, etc, etc)​
    As mentioned in post #1 - the B4A project also makes use of CustomViews. You therefore need to set the CustomType of the CustomView to IndeterminateProgressView once you have selected/enabled library IndeterminateProgressView in your B4A project and added additional/new CustomView views.
    By the way - the spinning circles in the attached project (and the project in post #1) simulates the Olympic symbol (blue, black, red, yellow, green). The spinning circle above it is a combination of all the colors used in the makeup of the Olympic symbol.
