Android13, SYSTEM_ALERT_WINDOW permission not checked in BroadcastReceiver

Question

I want to show a floating view when the user gets a phone call or a text message. But overlay permission check in broadcastReceiver returns false with built apk on Android 13.

I use BroadcastReceiver with RxWorker (more than 12) and Service (less than 12) to get a caller information. In Worker or Service, when you success to get a information, you call WindowManager.addview(mView). When the app is first launched, the user has already granted the permission to draw overlays.

        <receiver
            android:name=".receiver.PhoneCallReceiver"
            android:enabled="true"
            android:exported="true">
            <intent-filter>
                <action android:name="android.intent.action.PHONE_STATE" />
            </intent-filter>
        </receiver>

In this receiver, I check SYSTEM_ALERT_WINDOW permission by using Settings.canDrawOverlays(context). When I run this in Android Studio, it works well. However, permission is not checked when built with apk only on Android 13. Returns false even though you have permission. Sometimes, an error occurs when calling addView within Worker even if the permission is correctly confirmed on the broadcast!

"android.view.WindowManager$BadTokenException: Unable to add window android.view.ViewRootImpl$W@7c33a48 -- permission denied for window type 2038"

        <receiver
            android:name=".receiver.MessageReceiver"
            android:enabled="true"
            android:exported="true"
            android:permission="android.permission.BROADCAST_SMS">
            <intent-filter>
                <action android:name="android.provider.Telephony.SMS_RECEIVED" />
            </intent-filter>
        </receiver>

When receiving a phone call or text message, WindowManager.addView is called within the same worker, but the view is normally displayed when receiving a text message, and there is no permission when receiving a phone call. For your information, I'm testing with Samsung Galaxy S21.

Is there any solution?

Answer 1

It's an issue only with Android 13 Samsung phones.

I also contacted Samsung about the issue. And they replied:

they have SamsungRestrictOverlayProcessor. and Overlay-related permissions are temporarily disabled during calls for applications that have not been installed through an official store (Play store / Galaxy store) or ADB

so you need to distribute and test your application through proper stores.

I hope this was helpful to you.
