Android Question CircularProgressBar And Animation RotateCenter

[DarkWolfalpha]

Hi again
I use this CircularProgressBar and I want use Animation RotateCenter for panel CircularProgressBar
But I have Problem! (This rotation does not occur exactly around the axis)
This is my cod:

#Region  Project Attributes
    #ApplicationLabel: B4A Example
    #VersionCode: 1
    #VersionName:
    'SupportedOrientations possible values: unspecified, landscape or portrait.
    #SupportedOrientations: unspecified
    #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.

End Sub

Sub Globals

    Private CircularProgressBar1 As CircularProgressBar
    Private Panel1 As Panel
End Sub

Sub Activity_Create(FirstTime As Boolean)
    Activity.LoadLayout("1")

End Sub

Sub Button1_Click
    CircularProgressBar1.Value = Rnd(0, 101)
    Dim Anima As Animation
    Anima.InitializeRotateCenter("Animacirlce",0,720,Panel1)
    Anima.Duration = 1000
    Anima.Start(Panel1)
End Sub

Sub Activity_Click
    
End Sub

Sub Activity_Resume

End Sub

Sub Activity_Pause (UserClosed As Boolean)

End Sub

Sub Animacirlce_AnimationEnd
    Dim Anima As Animation
    Anima.InitializeRotateCenter("Animacirlce",0,720,Panel1)
    Anima.Duration = 1000
    Anima.Start(Panel1)
End Sub

(Gave wrong shake! Can See?)
