I would be good if you could attach the converted webp for inspection. Are you using the native android image decoder or libwebp directly?

This file has transparency [1]. Support at the android system level for lossless and lossy+alpha was added in 4.2.1 [2]. As a workaround you could create the image with 'cwebp -noalpha' or bundle the library with your app when dealing with older targets.

[1]
$ ./examples/webpmux -info messages.webp
Canvas size: 170 x 170
Features present: transparency
Size of the image (with alpha): 3326
