Picasso: Providing Vector Drawables as placeholder and/or error resource crashes with Resources$NotFoundException

[scholt]

   Picasso.get()
          .load("my image url")
          .placeholder(R.drawable.some_vector_fallback_drawable)
          .error(R.drawable.some_vector_error_drawable)
          .into(myImageView);

example stacktrace for different 4.4.2 devices:

Fatal Exception: android.content.res.Resources$NotFoundException: File res/drawable/no_image.xml from drawable resource ID #0x7f0801c0. If the resource you are trying to use is a vector resource, you may be referencing it in an unsupported way. See AppCompatDelegate.setCompatVectorFromResourcesEnabled() for more info.

[NightlyNexus]

Vector drawable support wasn't added until Android 5.

In the future, maybe you'll be able to make a request handler that uses the vector drawable compat library.
For now, you can set the image manually with the help of the Callback (into(view, callback)).

Hm yeah, I know I can handle this manually. But is there a specific reason why this is not handled by Picasso or at least a warning/lint error?

[NightlyNexus]

because Picasso doesn't include the vector compat support library.
Picasso 3 will require at least 21+. I'm not familiar with the vector compat library anymore, but if there are features in it that still apply to 21+ sdk versions, Picasso maybe should use it.
