Android

Adding Firebase Services

• To start you need a file called google-services.json. This file can be exported from the Firebase console. Move it to the root folder of your project.

• Add the services from indigitall to your AndroidManifest.xml as you can see below.

  XML

  <?xml version="1.0" encoding="utf-8"?>
  <manifest xmlns:android="http://schemas.android.com/apk/res/android">

  Push permission after Android 13 (Api level 33 - Tiramisu)

  Override onRequestPermissionsResult in the Main Activity:

  C#

   public override void OnRequestPermissionsResult(int requestCode, string[] permissions, Permission[] grantResults)
      {
          new Com.Indigitall.Maui.Platforms.Android.MIndigitall().OnRequestPermissionsResult(requestCode, permissions, grantResults);
      }
  

  Adding HMS Services

  🚧

  Huawei currently does not support the Maui SDK.

  Before you start, you have to add the following nuget package: Com.Indigitall.Xamarin.Hms

  1. To start you need a file called agconnect-services.json. This file can be exported from the Huawei developer console.

  2. Copy agconnect-services.json into the Assets folder of your project.

  3. Create a file HmsLazyInputStream.cs in the root of the project that will be used to read the content of agconnect-services.json.
     

  4. Add the following code in the AttachBaseContext of the MainActivity to call HmsLazyInputStream.cs:

  C#

  protected override void AttachBaseContext(Context context)
  {
      base.AttachBaseContext(context);
      AGConnectServicesConfig config = AGConnectServicesConfig.FromContext(context);
      config.OverlayWith(new HmsLazyInputStream(context));
  }
  

  5. Add the following code in HmsLazyInputStream.cs
  C#

  using System;
  using System.IO;
  using Android.Content;
  using Android.Util;
  using Com.Huawei.Agconnect.Config;
  
  namespace XamarinDemo.Droid
  {
      public class HmsLazyInputStream : LazyInputStream
      {
          public HmsLazyInputStream(Context context) : base(context)
          {
          }
  
          public override Stream Get(Context context)
          {
              try
              {
                  return context.Assets.Open("agconnect-services.json");
              }
              catch (Exception e)
              {
                  Log.Error(e.ToString(), "Can't open agconnect file");
                  return null;
              }
          }
      }
  }
  

  6. Add the HMS services indigitall in your AndroidManifest.xml.
  XML

  <!--HMS Services START-->
  <service android:name="Com.Huawei.Hms.Location.LocationServices"></service>
  <service android:name="com.indigitall.android.hms.services.HMSMessagingService" android:exported="false">
  			<intent-filter><action android:name="com.huawei.push.action.MESSAGING_EVENT" /></intent-filter>		
  </service>
  <!--HMS Services END-->
