BroadcastReceiver Not Firing after boot - xamarin.android

Question

Unable to get my Xamarin.Android app to fire Toast after boot. I checked many accepted solutions but none seem to resolve my problem. I've also tried various "working" examples but haven't had any luck so clearly I'm missing something.
Device: Samsung Galaxy S3
API: 19
Android Manifest
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.novak" android:versionCode="1" android:versionName="1.0" android:installLocation="auto">
<uses-sdk android:minSdkVersion="16" />
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
<application android:label="ReceiverApp">
<receiver android:enabled="true"
android:exported="true"
android-permission="android.permission.RECEIVE_BOOT_COMPLETED"

<intent-filter >
<action android:name="android.intent.action.BOOT_COMPLETED" />
<action android:name="android.intent.action.QUICKBOOT_POWERON" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</receiver>
</application>
</manifest>
BootReceiver.cs
using Android.App;
using Android.Widget;
using Android.Content;
namespace ReceiverApp
{
[BroadcastReceiver]
[IntentFilter(new[] { Intent.ActionBootCompleted })]
public class BootReceiver : BroadcastReceiver
{
public override void OnReceive(Context context, Intent intent)
{
Toast.MakeText(context, "Receiver", ToastLength.Long).Show();
}
}
}

Answer 1

It would appear that what I want to do is not possible. Once my app is installed the app sits in a stopped state and must be executed manually the first time before it can receive broadcasts

Answer 2

P.S: On real device it takes a while to fire the event, ie: 2 minutes after unlock the screen on my Samsung. On emulator it takes very short.
I wrote the code below to notice when it will fire:
Autorun.cs - Just add this file into your project, that's it, it will start after the boot. No manifest modification needed.
using Android;
using Android.App;
using Android.Content;
// we need to ask permission to be notified of these events
[assembly: UsesPermission (Manifest.Permission.ReceiveBootCompleted)]
namespace XamarinCookbook
{
// we want this to fire when the device boots
[BroadcastReceiver]
[IntentFilter (new []{ Intent.ActionBootCompleted })]
public class ServiceStarter : BroadcastReceiver
{
public override void OnReceive (Context context, Intent intent)
{
#region Start chrome
var mesaj = "Autorun started";
Android.Widget.Toast.MakeText(Android.App.Application.Context, mesaj, Android.Widget.ToastLength.Long).Show();
var uri = Android.Net.Uri.Parse("https://500px.com");
var intent1 = new Intent(Intent.ActionView, uri);
intent1.AddFlags(ActivityFlags.NewTask);
intent1.SetPackage("com.android.chrome");
try
{
context.StartActivity(intent1);
}
catch (ActivityNotFoundException ex)
{
//Chrome browser not installed
intent.SetPackage(null);
context.StartActivity(intent1);
}
#endregion
/*
#region Real code
// just start the service
var myIntent = new Intent (context, typeof(XamarinService));
context.StartService (myIntent);
#endregion
*/
}
}
}
