MediaStore Beispiele SDK für die Verwendung von Java 2.x

Die folgenden Codebeispiele zeigen Ihnen, wie Sie mithilfe von AWS SDK for Java 2.x with Aktionen ausführen und allgemeine Szenarien implementieren MediaStore.

Aktionen sind Codeauszüge aus größeren Programmen und müssen im Kontext ausgeführt werden. Während Aktionen Ihnen zeigen, wie Sie einzelne Servicefunktionen aufrufen, können Sie Aktionen im Kontext der zugehörigen Szenarien und serviceübergreifenden Beispiele sehen.

Szenarien sind Codebeispiele, die Ihnen zeigen, wie Sie eine bestimmte Aufgabe ausführen können, indem Sie mehrere Funktionen innerhalb desselben Services aufrufen.

Jedes Beispiel enthält einen Link zu GitHub, wo Sie Anweisungen zum Einrichten und Ausführen des Codes im Kontext finden.
