Well hello everybody. This is my first ever android project. I am trying to create a live wallpaper with a sequence of images gotten from a video. The dimensions of each image is 960 x 800. So far the live wallpaper works, but I still have issues I have not been able to solve.
When set, the live wallpaper only shows part of the whole png. I managed to get it to scroll through the images width, and it scrolls but it only shows part of the whole width. And it is only show part of the whole image's height, about until half of the image on portrait, and just a piece of it from top to bottom on landscape. I'd like the live wallpaper to look nice and get to fit the phone's screen on both portrait and landscape mode.
It works, but it kind of pauses. And it only keeps working when I switch screens. To be more specific in this issue is that when you set it it animates, but stops suddenly by half of the cycle, when you switch screens it keeps working a little bit more, meaning it advances a little on the sequence. And in order to finish the sequence and to start it over you need to keep going through the screens.
I would like the sequence to go faster, like it was a video.
