Loading Progress Indicator - Rotate Loading, Book Loading, Newton Cradle Loading

It wraps this Github project. All of the "Loading" indicators have some nice animations. Posting the B4A project, the B4A library files (including android-support-annotations.jar), and the Java code. Copy the library files to your additional library folder.

Sample code:

B4X:

#Region  Project Attributes
    #ApplicationLabel: Loading
    #VersionCode: 1
    #VersionName:
    'SupportedOrientations possible values: unspecified, landscape or portrait.
    #SupportedOrientations: landscape
    #CanInstallToExternalStorage: False
    #AdditionalJar: android-support-annotations
#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
    'These global variables will be redeclared each time the activity is created.
    'These variables can only be accessed from this module.
