Beginne beim Einstiegspunkt MyObjectBox.builder() und überprüfe das Ergebnis von SDCardUtils.getSDCardPathByEnvironment(), das an .directory(file) übergebene Verzeichnis und den gemeldeten Stacktrace. Reproduziere den Android-Startfehler, wenn möglich, und dokumentiere eine verifizierte Ursache und Behebung für den Fehler „No DB catalog present“.
