I've never had any luck with those convert sites. You're better off using photo tools to create an SVG. Make sure to follow the SVG guidelines from Android listed here

Most of the complaints on this topic are due to people trying to convert SVGs that use features of the SVG standard that are not supported by VectorDrawables. And the SVG to VectorDrawable converter in AndroidStudio only supports those limited features. It doesn't really give much feedback when it encounters things it doesn't support.

Some of the online converters try a bit harder. You might have better success with them. Otherwise you may have to simplify your SVGs to get them to work.

If you need to display SVGs images that are more complicated than VectorDrawables can handle, then you can always consider using an SVG rendering library for Android. IMHO the best one is AndroidSVG (disclaimer I wrote that one).

There are some cases when your actual .svg file name contains some capital letters. Just rename them in all small letters and try to upload it.

For instance: If actual .svg image name is mySavedimage.svg {here 'S' is capital which is against norms of android assets}. SO if you rename that file to my_saved_image.svg then this will work as a charm.

hope it helps.
