Migration and Precedence

To migrate from manual code-based initialization to the XML file-based approach, follow the below steps:

Add Configuration File: Place the moengage_config file in the (src/main/assets/moengage.xml) path.
Update Application Class: Remove the existing initialization code (the manual MoEngage.Builder logic) from your Application class and replace it with the default instance initialization to enable reading from the XML file.

Code Language	Existing Code	Replace with
Kotlin	`val moEngage: MoEngage.Builder = MoEngage.Builder(this,“YOUR_Workspace_ID”, DataCenter.DATA_CENTER_X) MoEInitializer.initialiseDefaultInstance(context = this, builder = moEngage)`	`MoEInitializer.initializeDefaultInstance(application)`
Java	`MoEngage.Builder moEngage = new MoEngage.Builder(this, “YOUR_Workspace_ID”, YOUR_DATA_CENTER); MoEInitializer.initialiseDefaultInstance(this, moEngage);`	`MoEInitializer.INSTANCE.initializeDefaultInstance(this);`

To migrate from code-based initialization to the Info.plist based approach, follow these steps:

Update Info.plist: Add the required MoEngage configuration keys (e.g., WorkspaceId, DataCenter) inside the MoEngage key in your Info.plist file.
Update AppDelegate: Remove the existing initialization code (the manual MoEngageSDKConfig logic) from your AppDelegate class and replace it with the default instance initialization to enable reading from the Info.plist file.

Code Language	Existing Code	Replace with
Swift	`MoEngageInitializer.sharedInstance.initializeDefaultInstance(sdkConfig, launchOptions: launchOptions)`	`MoEngageInitializer.sharedInstance.initializeDefaultInstance()`
Objective-C	`[[MoEngageInitializer sharedInstance] initializeDefaultInstance:sdkConfig launchOptions:launchOptions];`	`[MoEngageInitializer.sharedInstance initializeDefaultInstance];`

The source of configuration is determined by the initialization function called in your native code:

Android:
- File-Based Init: Calling MoEInitializer.initializeDefaultInstance(context) instructs the SDK to look for and read the moengage.xml file.
- Code-Based Init: Calling MoEInitializer.initialize(context, moEngage.Builder) will initialize the SDK using the configuration object passed in the parameters, ignoring the XML file even if it exists.
iOS: Auto-initialization (via Info.plist) occurs first. However, if you subsequently call the manual initialize method with a configuration object in your code, it will update the current instance configuration.
