B4A Library DilatingDotsProgressBar

It wraps this Github project. Posting the following:
1. B4A library files
2. B4A project (demonstration purposes)
3. The Java code


Sample code:

#Region  Project Attributes
    #ApplicationLabel: DilatingDotsProgressBar
    #VersionCode: 1
    'SupportedOrientations possible values: unspecified, landscape or portrait.
    #SupportedOrientations: landscape
    #CanInstallToExternalStorage: False
#End Region

#Region  Activity Attributes
    #FullScreen: False
    #IncludeTitle: True
#End Region

Sub Process_Globals
    'These global variables will be declared once when the application starts.
    'These variables can be accessed from all modules.
    Dim t As Timer

End Sub

Sub Globals
    'These global variables will be redeclared each time the activity is created.
    'These variables can only be accessed from this module.

    Private ddpb1 As DilatingDotsProgressBar
End Sub

Sub Activity_Create(FirstTime As Boolean)
    'Do not forget to load the layout file created with the visual designer. For example:
    t.Initialize("t", 2000)
    ddpb1.DotColor = Colors.Blue
    ddpb1.GrowthSpeed = 300
    ddpb1.DotSpacing = 10
    ddpb1.DotScaleMultiplier = 1.9
    ddpb1.NumberOfDots = 10
    ddpb1.DotRadius = 6

End Sub

Sub Activity_Resume
    t.Enabled = True

End Sub

Sub Activity_Pause (UserClosed As Boolean)
    t.Enabled = False

End Sub

Sub t_tick

    ddpb1.DotColor = Colors.RGB(Rnd(150,256), Rnd(150, 256), Rnd(150, 256))
    ddpb1.GrowthSpeed = Rnd(100, 501)
    ddpb1.DotSpacing = Rnd(5,16)
    ddpb1.DotScaleMultiplier = 1.9
    ddpb1.NumberOfDots = Rnd(3, 16)
    ddpb1.DotRadius = Rnd(5, 11)  
End Sub
