Xamarin-android: Implicit BroadcastReceiver does not work

Created on 19 Apr 2018 · 3Comments · Source: xamarin/xamarin-android

Steps to Reproduce

Create a BroadcastReceiver that listens to the boot completed intent
Open the app at least once
Restart your device

Tested on a Pixel 2 with Android 8.1

I have a repro project, but I can't share it publicly.
Broadcast receiver:

[assembly: UsesPermission(Name = Manifest.Permission.ReceiveBootCompleted)]

namespace Something
{
    [BroadcastReceiver(Enabled = true, DirectBootAware = true)]
    [IntentFilter(new[] {Intent.ActionLockedBootCompleted, Intent.ActionBootCompleted}, Categories = new []{Intent.CategoryDefault})]
    public class BootedBroadcastReceiver : MvxBroadcastReceiver
    {
        public override void OnReceive(Context context, Intent intent)
        {
// it does not even reach this point
            base.OnReceive(context, intent);
            Log.Info("Boot message received");
            ForegroundSyncService.Start(context);
        }
    }
}

I think this relates to https://bugzilla.xamarin.com/show_bug.cgi?id=51940

Expected Behavior

The code in the broadcast receiver runs.

Actual Behavior

The process/app crashes with the error No implementation found for void mono.android.Runtime.register(java.lang.String, java.lang.Class, java.lang.String) (tried Java_mono_android_Runtime_register and Java_mono_android_Runtime_register__Ljava_lang_String_2Ljava_lang_Class_2Ljava_lang_String_2)

Exactly the same bug occurs here. Any fix or work-around would be great.

subsembly on 13 Aug 2018

I'm here because I think I have the same problem. I've created a BroadcastReceiver class in order to do push notifications for Android. The weird thing is when I test my application on a Samsung Galaxy S8+ running Android 8.0 it will always execute the code within the OnReceive override. When I test it on a newer Pixel 3XL running Android 9.0 it never reaches the code. Very strange.
