In order for their own app to make the leap to Android 13 without stumbling, developers have to lend a hand. The privacy innovations in particular are treacherous.
From one day to the next there are complaints about notifications that are no longer displayed – a horror scenario that is unfortunately realistic with the update to Android 13. If developers want to avoid this, they must now adapt their applications.
If you work a lot with notifications, you could soon see them completely blocked by the latest privacy improvements: Starting with targetSdkVersion 33, you need to request permission POST_NOTIFICATIONS with the usual suspects checkSelfPermission(), shouldShowRequestPermissionRationale() and requestPermissions().
In addition, one should use the NotificationManager function available since API level 24 – Android 7.0 areNotificationsEnabled() make sure that the sending of messages is not blocked. This can also happen if permission is granted.
