Mi BaseActivity es algo como:

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}")
}
}
}

Esto se resuelve con Clean Project y Rebuild.

Aún así, me gustaría entender por qué sucede esto y cómo prevenirlo.

Nota: Esto me ha sucedido mientras utilizaba una Proguard depuración que no tiene Proguard u otras cosas por el estilo.

Answer 1

La solución es especificar el tipo exacto de su variable, la inferencia de tipos no funciona en este caso por algún motivo (probablemente un error de Kotlin).

Así que en lugar de esto:

private val broadcastReceiver = object : BroadcastReceiver()

Utilizar esta:

private val broadcastReceiver: BroadcastReceiver = object : BroadcastReceiver()

Answer 2

Para completar: declarar la variable como obras protected también.

protected val broadcastReceiver = object : BroadcastReceiver()

Me imagino cualquier cosa además de private obras private .

Answer 3

Parece un error y creo que debería estar en el rastreador de problemas de Kotlin, pero supongo que puedes arreglarlo por ahora definiendo receptor como una clase:

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}")
}
}
}
