i have this error too

It seems there is a conflict with the library versions, downgrading Picasso and using PicassoEngine fix it for me:

implementation 'com.squareup.picasso:picasso:2.5.2'

.imageEngine(new PicassoEngine())

Got the idea by looking at this https://github.com/zhihu/Matisse/blob/35f46b58a1ea1610fabf33cdf5a9fd0acc41d05d/matisse/build.gradle#L49

Excuse me but why this is closed? The problem is related with the gradle configuration of the library. I can see 2 fixes:

• Lock dependencies, add in the docs the warning that specific versions of Picasso or Glide must be used when using this library
• Transitive dependencies, whatever other dependency used on the project should not conflict with the library dependencies
