Wallpaper Swapper

いいえグリッツません！大騒ぎ！簡単に理解し、壁紙のSwapperを使用します。

An easy to use and simple to understand app, that allows the selection of any number of images, from various image sources (Google drive doesn't work), and displays those images as wallpapers on your phone or tablet.

FEATURES

A simple and easy to understand user interface - unlike some of the convoluted nightmares I've seen.

Allows fine grained setting of the interval between wallpaper changes, in seconds, minutes or hours.

Minimum interval is 10 seconds.

Maximum interval... Errrmmmm... a very very long time.

Will "intelligently" rotate images to best fit the aspect ratio of your Android device, without savagely cropping the images.

Easily change the order in which wallpapers are displayed.

Easily remove all images or single images.

Remote images are copied to a local cache.

Darkness of the wallpaper is configurable, to ensure good contrast between icons and the wallpaper.

Senses device rotation (on devices, like tables, that rotate the wallpaper), and will automatically reorientate the wallpaper, so that it remains nicely sized to the dimensions of your device.

Senses "screen on" and "screen off" conditions, so there is no unnecessary power usage while your device is "asleep."

Optionally set the swapper to start automatically on device boot.
