out of memory Ausnahme mit gleiten und ViewPager

Question

Ich habe eine Galerie von Bildern, die die Bilder in einer Recyclerviewglide und durch Klicken auf jedes Bild in der Recyclerview das Bild in einer Ansicht Pager öffnen. Alles ist in Ordnung am Anfang ist die Recyclerview in Ordnung, die Bilder in einem Viewpager öffnen und in Viewpager schieben sind alles in Ordnung. aber wenn ich zurück drücke, um den Viewpager zu schließen und zur Recyclerview zurückzugehen, erhöht sich der zugewiesene Speicher auf ungefähr 400 MB !!! gibt es 8 Bilder, die etwa 490 * 420 Pixel und 72 KB groß sind.
