Passing a custom object to BroadcastReceiver results via intent returns null

[Deleted User]

I'm trying to pass a custom data class object from a foreground service to a BroadcastReceiver. I have tried using Parcelable, Parcelize and Serializable, but the BroadcastReceiver intent always reports it as null.

I have wasted a couple of days searching for an answer and have looked at some of the threads here and elsewhere. The accepted answers that work for others are not working for me.

Here's the service:

class MyService : Service(){

............
<Some code that initialises alarmTimeInMillis>
............

   private fun sendDataToReceiver(){
      val intentMyRcvr : Intent = Intent("Data", null, this, MyReceiver::class.java)
      intentMyRcvr.addFlags(Intent.FLAG_RECEIVER_FOREGROUND)
      val bundle = Bundle()
      val myParcel = MyParcel(dataP.Id, dataP.Location, dataP.Title, dataP.Description, dataP.Type)
      bundle.putParcelable("MyParcel", MyParcel)
      intentMyRcvr.putExtras(bundle)
      val pendingIntentMyRcvr= PendingIntent.getBroadcast(this, dataP.Id, intentMyRcvr, PendingIntent.FLAG_UPDATE_CURRENT)
      val alarmManager = getSystemService(Context.ALARM_SERVICE) as AlarmManager
      alarmManager.setWindow(AlarmManager.RTC_WAKEUP, alarmTimeInMillis, 5 * 60 * 1000, pendingIntentMyRcvr)
   }
}

Here's the BroadcastReceiver:

class MyRcvr : BroadcastReceiver() {

   override fun onReceive(context: Context, intent: Intent) {
       if (intent.action == "Data") {
           val bundle = intent.getBundleExtra("MyParcel")
           val myParcel = bundle.getParcelable<MyParcel>("MyParcel")

           val intentToService = Intent("Data", null, context, MyService::class.java)
           if (myParcel != null) {
               intentToService.putExtra("MyParcel", MyParcel)
               context.startService(intentToService)
           }
       }
   }
}

Here's the Parcelize data class:

@Parcelize
data class MyParcel(
   var Id: Int = 0,
   var Location: String,
   var Title: String,
   var Description: String,
   var Type: String,
) : Parcelable

I've also tried without using Bundle i.e. directly passing the parcelable object. Neither produces any error in the service but, the the rceiver always reports it as null. I have included the stack trace from logcat:

I am beginning to wonder if it is a bug in the latest SDK or Kotlin Plugin. Any ideas what I might be doing wrong ?

Not sure if it will work but can you try adding the following code line after you add your bundle ?

intentMyRcvr.setData(Uri.parse(intent.toUri(Intent.URI_INTENT_SCHEME)));

or

change PendingIntent.FLAG_UPDATE_CURRENT to CANCEL_CURRENT
