Start activity from receiver in Android Q

I'm checking my app with the Android Q [beta 6] in order to add all the required changes to be fully-compatible with the last SO. However, I found out that I am using a Receiver to start an Activity from background and due to the last background limitations implemented (https://developer.android.com/preview/privacy/background-activity-starts) the activity is not being opened.

I tried to use both the receiver context and application context to start the activity but in both cases the system shows a toast saying that is not possible to start activity from background.

What I tried on the Receiver...

class MyReceiver : BroadcastReceiver() {

    override fun onReceive(context: Context?, intent: Intent?) {
        context?.applicationContext?.let {
            it.startActivity(Intent(it, MyActivity::class.java).apply {
                addFlags(Intent.FLAG_ACTIVITY_NEW_TASK)
            })
            PushUtils.showReceiverCalledNotification(it)
        }
    }

That way I wanted to start MyActivity and also show a notification when the receiver is called. Instead, I can see the notification but the Activity is never started. It is very important for the feature to start the activity immediately, so there is a way to continue starting the activity from the receiver?

Solution

  • It is very important for the feature to start the activity immediately, so there is a way to continue starting the activity from the receiver?

    No, sorry. Use a high-priority notification, so it appears in "heads-up" mode. The user can then rapidly tap on it to bring up your activity.
