B4A Library General IR Remote

It relates to this posting where I said I will provide for 50 commands. Attached a B4A sample project that switches On/Off my air conditioner. I am sure you will get the drift of what to do with it - you need to find the cycle times for the commands that you want to make use of and pass them as an array of int to the library to control whatever it is that you would like to control. You can pass whatever commands you would like to pass to control your device(s) - as many as you want

Please note that this B4A project was done with B4A V6.80
Take note of the B4A manifest file

Your device must support an IR Blaster

Also posting the B4A library files (GeneralIRcontrol.zip).Extract the jar and xml and copy them to ylour additional library folder.

Sample code:

B4X: 
#Region  Project Attributes
    #ApplicationLabel: b4aGeneralIRremote
    #VersionCode: 1
    #VersionName:
    'SupportedOrientations possible values: unspecified, landscape or portrait.
    #SupportedOrientations: portrait
    #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
    'These global variables will be redeclared each time the activity is created.
    'These variables can only be accessed from this module.
