Pre-requisites

Here are the pre-requisites for enabling the Calling UI Framework in your existing application:

  • Application must have enabled VoIP feature in background mode.
  • You need to integrate your own Notification Service, as no built-in notification service is provided.

How to integrate in Android Native App?

For Calling UI Framework integration in Android, create an instance of EnxCallKitView class and handle Callback functions

  • Observer: EnxCallKitStateObserver
  • Class: EnxCallKitView // Create an instance of this Class.
  • Parameters:
    • this: Pass reference of your activity
    • name: Name of the caller
    • int: reference of icon
    • this: reference of Observer
  • Callbacks:
    • callAnswer(): When you receive incoming call
    • callReject(): When you reject incoming call
    • callTimeOut(): When you didn’t respond to incoming call notification, it times out in 45 seconds.
var callKitView = EnxCallKitView.getInstance(
	this@ConferenceActivity,
	"name", 
	com.enxcallkit.R.mipmap.ic_launcher_round,
	this) 

override fun callAnswer() { 
    // When you receive incoming call 
} 
 
override fun callReject() { 
    // When you reject incoming call
} 
  
override fun callTimeOut() { 
    // When you didn't respond to incoming call notification, 
    // it times out in 45 seconds.
}
