Kotlin: classe locale non résolue lors de l'utilisation de BroadcastReceiver dans Activity

De temps en temps lors de la compilation du projet, l'erreur suivante apparaît:

Mon activité de base est quelque chose comme:

abstract class BaseActivity : Activity {

    companion object {
        private const val LOG_TAG = "BaseActivity"
    }

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)

        LocalBroadcastManager.getInstance(this).registerReceiver(broadcastReceiver,
                IntentFilter(MY_FILTER))
    }

    override fun onStop() {
        super.onStop()
        if(isFinishing){
            LocalBroadcastManager.getInstance(this).unregisterReceiver(broadcastReceiver)
        }
    }

    private val broadcastReceiver = object : BroadcastReceiver() {
        override fun onReceive(context: Context?, intent: Intent?) = when (intent?.action) {
            MY_FILTER -> Log.d(LOG_TAG, "This is my filter!")
            else -> Log.e(LOG_TAG, "Hello action ${intent?.action}")
        }
    }
}

Ceci est résolu par Clean Project et Rebuild. 

Je voudrais quand même comprendre pourquoi cela se produit et comment l'éviter.

Remarque: cela m'est arrivé lorsque j'ai utilisé une version de débogage qui n'a pas de variable Proguard ou autre chose du genre.

Le correctif consiste à spécifier le type exact de votre variable, l'inférence de type ne fonctionne pas dans ce cas pour une raison quelconque (probablement un bogue de Kotlin).

Donc au lieu de cela:

private val broadcastReceiver = object : BroadcastReceiver()

Utilisez ceci:

private val broadcastReceiver: BroadcastReceiver = object : BroadcastReceiver()

Cela ressemble à un bug et je pense que cela devrait être sur le système de suivi des problèmes de Kotlin, mais je suppose que vous pouvez le résoudre pour le moment en définissant receiver comme une classe:

abstract class BaseActivity : Activity {

    companion object {
        private const val LOG_TAG = "BaseActivity"
    }

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)

        LocalBroadcastManager.getInstance(this).registerReceiver(broadcastReceiver,
                IntentFilter(MY_FILTER))
    }

    override fun onStop() {
        super.onStop()
        if(isFinishing){
            LocalBroadcastManager.getInstance(this).unregisterReceiver(broadcastReceiver)
        }
    }

    private val broadcastReceiver = MyBroadcastReceiver()

    inner class MyBroadcastReceiver : BroadcastReceiver() {
        override fun onReceive(context: Context?, intent: Intent?) = when (intent?.action) {
            MY_FILTER -> Log.d(LOG_TAG, "This is my filter!")
            else -> Log.e(LOG_TAG, "Hello action ${intent?.action}")
        }
    }
}

Pour être complet: Déclarer la variable en tant que protected fonctionne également.

protected val broadcastReceiver = object : BroadcastReceiver()

J'imagine autre chose que private qui fonctionne.
