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.

Looks like it wants a drawable, and you are providing a `raw` resources. AndroidSVG allows you to parse and render SVGs to a canvas, but not to assign them to an ImageView, afaik. SVGAndroid gets you a bit closer. — 323go, Mar 16 '16 at 05:05
@323go I understand that it is asking for a drawable, but to my understanding AndroidSVG and or api 23 allows the use of svgs and gradle creates the appropriate pngs at build — linuxer, Mar 16 '16 at 05:21
`official support for SVG didn't start until api level 23` It **never** started, for real. `VectorDrawables` are **not** `SVG`s. They use a reduced **subset** of the `SVG` definition. — Phantômaxx, Mar 16 '16 at 08:04
Is there anything weird in your proguard file? Otherwise perhaps try changing one thing at a time in your release build to match the debug one and see if it starts working. — Paul LeBeau, Mar 16 '16 at 14:49
@PaulLeBeau I commented out the proguard and I still have the problem. I also went through and changed things like by line. Nothing worked — linuxer, Mar 16 '16 at 16:10

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.

I am actually using an SvgImageView. Sorry, I inherited this code, and I am not an android guru by any means. Can you explain to me how I can do a debug build and it works just fine, no issues, but once I try a release build then it has issues? – linuxer Mar 16 '16 at 12:38
Ok then. I was confused by your error because that is not one I'd expect to get when using AndroidSVG. What are the difference in your debug and release buiids. Can you post your build.gradle file to the question? – Paul LeBeau Mar 16 '16 at 13:05
Ok, I added the build.gradle I removed some of the sensitive info, but nothing that effects the build. – linuxer Mar 16 '16 at 13:30
