This post seems really helpful, as I am having trouble displaying a transparent gif in mit app inventor. The method I was using before (file:///android_asset/nameoffile.gif) is working (aka the gif is playing), but the gif's background is showing up as white, not transparent. However, I am having trouble understanding your code. Where is the block "KIO3_AniGif1. Load Gif" coming from? I do not see it anywhere in my blocks window, even under the image component blocks.
That block is in the extension.
Some animated gifs don't work with transparent background with this extension. Try to set the background color of the screen.
What version of Android are you using?
Can you upload your gif file to this topic? (in this topic your gif will not be animated)
Is there a way to download the extension?
Also, I am using an ipad with ios14 to test my app, and it is on the ipad where the gif background becomes white. The webviewer in which I am displaying the gif is on a screen with an image backdrop. I can tell that the gif background is white because when I run the app it plays but covers part of the backdrop of the screen. My gif file is a sticker from GIPHY with a transparent background (dog jumping)
if you are using the ios companion then extensions will not work.
