Please ignore my ignorance. I would like to "install" a series of videos on one of the home screens to be played from the device (not online like YouTube). I would also like to know how to create a "PowerPoint" style presentation that would also run from the device and allow slides to be swiped back and forth, and even video or audio on some slides. Transitions between slides??? All to be done from the Android device. Is there a way to do these things? And How hard is it? Thank you.
