CT Push Migration

JIRA Issue	SDK-2316

Background

Support Notifications from both Leanplum and CleverTap

CT swizzling is not called (no swizzling of iOS delegate methods) when using a custom instance and the method is internal.
Instead of using double swizzling, check if the notification comes from Leanplum and if not, forward it to CleverTap to handle it using the CleverTap.handlePushNotification method.

Implementation

Create a new NotificationsManager that inherits from it and handles both CT and LP notifications. Override the push receive and open methods. Call the corresponding SDK based on the push payload. Handle registration with a device token as well.

For CT, ensure that CleverTap.handlePushNotification and CleverTap.setPushToken methods are called once we have an instance initialized.
Set the push token when the CT instance is initialized, based on the token cached by Leanplum, using instance.setPushTokenAs.

The Leanplum Notifications Object is also modified to not filter out the notifications. This logic is moved to the NotificationsManager.

Note that CT does not send the "content-available" flag, so the app will not be woken up by a CT notification.

Example payloads

Leanplum

{
   "_lpn":5187874616049123,
   "aps":{
      "alert =""Push message goes here.",
      "content-available"= 1,
      "mutable-content"= 1
   },
   "_lpx":{
      "__name__""="""
   },
   "LP_URL":"https":,
   "apns-push-type":"alert"
}

CleverTap

{
   "W$rnv":0,
   "wzrk_dl":"https":,
   "W$pivot":"wzrk_default",
   "ct_mediaType":"image",
   "wzrk_acct_id":W84-WW7-123A,
   "ct_mediaUrl":"https"://db7hsdc8829us.cloudfront.net/...,
   "W$dt":"APPLE",
   "W$id":0_0,
   "aps":{
      "alert ="{
         "body = message",
         "title = hello"
      };
    badge = 3,
      "mutable-content"= 1
   }
}

Testing steps

Testing Push is received and opened when:

• the app is not running
• the app is not running, and the app is woken up by push (Background Mode: Remote notification)
• the app is running in background
• the app is on foreground

Is this change backwards-compatible?

Yes
