How do I use SVGs in android correctly?

Question

I know that official support for SVG didn't start until api level 23, but how do I use it in an app with the min sdk at 17?

I have had it working before, and I don't know what changed. I am using AndroidSVG library.

I get this error when I try to build a production APK

Error:(163) Error: Expected resource of type drawable [ResourceType]

Here is one of the 150 lines of code that I get this error in

socialTypeImage.setImageResource(R.raw.icon_other_blue);

I don't know what other info to provide, so if you need more, please let me know.

Thanks

I don't know if my problem is a duplicate, but if it is, none of those solutions work.

You can't use SVGs directly as a Resource. The Android resource loading system doesn't know what an SVG is. What you need to use is something like:

SVG svg = SVG.getFromResource(R.raw.icon_other_blue);
socialTypeImage.setImageDrawable(new PictureDrawable(svg.toPictureDrawable()));

Or you can use the SVGImageView widget class that is provided. Documentation here.
