Das Bild kann nach dem Verschlüsseln nicht von der Galerie auf die SD-Karte verschoben werden

Das Bild kann nach dem Verschlüsseln nicht von der Galerie auf die SD-Karte verschoben werden

Ich versuche, ein Bild aus der Galerie zu verschlüsseln und auf der SD-Karte zu speichern.

Wenn ich versuche, das Bild von der Galerie auf die SD-Karte zu verschieben, wird der Fehler "Schließen erzwingen" angezeigt und logcat zeigt keine Ausnahme an.

Ich bekomme einen Toast mit der Meldung "Bild erfolgreich verschlüsselt", aber das Bild wird nicht von der Galerie auf die SD-Karte verschoben.

Was mache ich falsch?
