How do you configure the Pushwoosh plugin for both Android and iOS in MvvmCross

Prerequisites

Before starting, ensure you have the following:
- MvvmCross Framework: Set up in your project.
- Pushwoosh Account: Create an account and obtain your Pushwoosh Application ID and API Token.
- Google Firebase Account: For Android, you need a Firebase project to enable Firebase Cloud Messaging (FCM).

Step 1: Install the Pushwoosh Plugin for MvvmCross

You can install the Pushwoosh plugin for MvvmCross using NuGet. This plugin wraps the native Pushwoosh SDKs for Android and iOS, simplifying the integration process.

bash
Install-Package MvvmCross.Plugin.Pushwoosh

Step 2: Configure Android

2.1 Set Up Firebase Cloud Messaging

1. Create a Firebase Project: Go to the Firebase Console and create a new project.
2. Enable Cloud Messaging: In your project settings, navigate to the Cloud Messaging tab and note the Server Key and Sender ID.
3. Download `google-services.json`: This file is required for your Android project.

2.2 Integrate Pushwoosh Android SDK

1. Add NuGet Packages: Install the necessary NuGet packages for Firebase and Pushwoosh.
2. Configure AndroidManifest.xml: Add metadata for Pushwoosh Application ID and Firebase Sender ID.
3. Register for Push Notifications: Implement the initialization code to register your app for push notifications.

Step 3: Configure iOS

3.1 Set Up Push Notifications

1. Enable Push Notifications Capability: In Xcode, add the Push Notifications capability to your project.
2. Add Background Modes Capability: Enable Remote notifications.
3. Install Pushwoosh SDK: Use Swift Package Manager or CocoaPods to integrate the Pushwoosh iOS SDK.

3.2 Configure Info.plist

1. Set Pushwoosh_APPID: Add your Pushwoosh Application ID to Info.plist.
2. Set PW_API_TOKEN: Add your Pushwoosh API Token to Info.plist.

Step 4: Implement Pushwoosh Initialization in MvvmCross

In your MvvmCross setup, initialize Pushwoosh with your Application ID and other necessary settings. This typically involves adding initialization code in your platform-specific setup classes.

Example Initialization Code

For Android, you might initialize Pushwoosh in a custom `Setup` class:

csharp
public class Setup : MvxAndroidSetup
{
    public Setup(Context applicationContext, IMvxAndroidGlobals globals) 
        : base(applicationContext, globals)
    {
    }

    protected override void InitializePlatformServices()
    {
        base.InitializePlatformServices();

        // Initialize Pushwoosh here
        // This involves setting up Firebase and Pushwoosh
    }
}

For iOS, initialization might look similar but will involve setting up APNs and Pushwoosh:

csharp
public class Setup : MvxIosSetup
{
    public Setup(IMvxApplicationDelegate applicationDelegate, IMvxIosGlobals globals) 
        : base(applicationDelegate, globals)
    {
    }

    protected override void InitializePlatformServices()
    {
        base.InitializePlatformServices();

        // Initialize Pushwoosh here
        // This involves setting up APNs and Pushwoosh
    }
}

Step 5: Handle Push Notifications

Implement event handlers to manage incoming push notifications. This includes displaying notifications and handling user interactions with them.

Troubleshooting

If you encounter issues, ensure that your Firebase and Pushwoosh configurations are correct, and that you have properly registered for push notifications in both platforms.

By following these steps, you should be able to successfully configure the Pushwoosh plugin for both Android and iOS in your MvvmCross application.
