Android 8.1.0 "API 27" (Permision denial: android.permission.WRITE_EXTERNAL_STORAGE don't work)

I catch an error on API 27:

2022-10-05 13:49:41.061 16988-17081/com.example.background E/MediaStore: Failed to insert image

This permission is mensioned in manifest (see screenshot)

How to fix this error on API 27?

Beginne bei SaveImageToFileWorker.kt Zeile 40, wo der Stacktrace für API 27 zeigt, dass der MediaStore-Schreibvorgang fehlschlägt, und überprüfe die Berechtigungsdeklaration im Manifest. Reproduziere den Fehler unter Android 8.1/API 27; abgeschlossen ist die Aufgabe, wenn der Worker das Bild ohne die gemeldete SecurityException in den MediaStore schreiben kann.
