In here, I’m showing how to setup an Android app using App Inventor to flip through a series of images using Canvas and sprites. The sprites are used for PREV and NEXT buttons and their visibility is set or reset first or last page is reached. For example, if showing image1, then PREV is hidden and when on last page, NEXT is hidden.
The Blocks Editor and Designer Editors are shown below. The source for this can be downloaded from HERE.
