Androidのギャラリーで写真を移動
Stock Android Gallery does not have the possibility to move photos. Ever wanted to create a new album? Not possible without third-party gallery apps.
This app provides an entry in the share menu. Select photos you want to move and share with "Share to folder"! It will show a file manager to choose the new file location. You can also copy photos instead of moving them.
So you can keep the nice stock Android Gallery by Google AND create new albums!
