How do you integrate the Pushwoosh plugin with an existing MvvmCross project

1. Install the Pushwoosh Plugin

First, you need to install the Pushwoosh plugin for MvvmCross in your project. This plugin wraps the native Pushwoosh SDK for Android and iOS, allowing you to handle push notifications across platforms.

- For Android and iOS:**
- Open your project in Visual Studio.
- In the NuGet Package Manager, search for the "Pushwoosh plugin for MvvmCross."
- Install the package in both your Core project and platform-specific projects (Android and iOS).

2. Configure Firebase for Android

To use Pushwoosh with Android, you need to set up Firebase Cloud Messaging (FCM).

- Step 1: Set Up Firebase Cloud Messaging**
- Go to the Firebase Console and create a new project.
- Add your Android app to the project by following the wizard instructions.
- This will generate a `google-services.json` file that you need to add to your Android project.

- Step 2: Add Firebase Credentials**
- In the Firebase Console, navigate to Project settings > Cloud Messaging.
- Note down the Server Key and Sender ID. You will need these later.

3. Add Pushwoosh Metadata to AndroidManifest.xml

Open your `AndroidManifest.xml` file and add the following metadata inside the `` tag:

xml

Replace `YOUR_PUSHWOOSH_APP_ID` with your Pushwoosh Application Code and `YOUR_FCM_SENDER_ID` with the Sender ID from Firebase.

4. Initialize Pushwoosh in Android

In your Android project, initialize Pushwoosh by adding the necessary code to your application's startup logic. This typically involves calling the Pushwoosh initialization method in your `MainActivity` or equivalent.

5. Configure Pushwoosh for iOS

For iOS, you can use the Pushwoosh SDK directly or through the MvvmCross plugin.

- Step 1: Install Pushwoosh SDK**
- You can use CocoaPods or Swift Package Manager to install the Pushwoosh SDK in your iOS project.

- Step 2: Enable Push Notifications**
- In Xcode, go to your project's Signing & Capabilities section.
- Add the Push Notifications capability.
- Also, add Background Modes and check Remote notifications.

- Step 3: Add Pushwoosh Metadata to Info.plist**
- Open your `Info.plist` file and add the following keys:

xml
    Pushwoosh_APPID
    YOUR_PUSHWOOSH_APP_ID
    PW_API_TOKEN
    YOUR_PUSHWOOSH_API_TOKEN
    

6. Initialize Pushwoosh in iOS

In your iOS project, initialize Pushwoosh by adding the necessary code to your `AppDelegate` class.

7. Ensure Plugin Loading

If you're using MvvmCross version 6.0.0 or later, plugins are loaded automatically. However, if you're using an earlier version, you might need to manually add a bootstrap file to ensure the plugin is loaded.

Example Bootstrap Class (for older MvvmCross versions)

csharp
using System;
using MvvmCross.Platform.Plugins;

namespace YourNamespace.iOS.Bootstrap
{
    public class PushwooshPluginBootstrap
        : MvxPluginBootstrapAction
    {
        // This ensures the Pushwoosh plugin is loaded
    }
}

Final Steps

- Test Push Notifications:**
- Build and run your project on both Android and iOS devices.
- Go to the Pushwoosh Control Panel and send a push notification to test if it works correctly.

By following these steps, you should be able to integrate the Pushwoosh plugin with your existing MvvmCross project and handle push notifications across Android and iOS platforms.
