You need to use it BEFORE your Android compilation (and only once per SVG file).\n\n## Why?\n\nI want to use a scalable image format.\n\nA SVG sounds really good but it's a bit long to load (mainly the time to parse the XML) and I didn't find any library that support the Hardware acceleration.\n\n## How does it work?\n\nMy main goal is to have a [Drawable](http://developer.android.com/reference/android/graphics/drawable/Drawable.html) class:\n\n* Made a fork of the [svg-android](https://code.google.com/p/svg-android/) library.\n* Replaced any instructions to create a [Picture](http://developer.android.com/reference/android/graphics/Picture.html) to collect them into a Logger.\n* Print this Logger.\n* Save it to a Drawable java class.\n\n## How to use it?\n\nYou can read the code but I'm not proud of it. I started to do a POC for a basic usage and now I need to transform the code to make it more readable and robust.\n\nYou can simply use the [jar provided into this repo](https://github.com/StanKocken/SVG2Drawable/blob/master/svg_converter.jar) by specify:\n\n* the SVG file\n* the package where you want to put the Drawable\n* the drawable name\n\nYou can also specify the output of the script to create a file. By adding \"> filename.java\".\n\n\n java -jar svg_converter.jar example.svg com.skocken.svg.example.drawable ExampleDrawable > ExampleDrawable.java\n\nNow, copy this \"ExampleDrawable.java\" into your Android project, into the package \"com.skocken.svg.example.drawable\" (from this example), and add it to your ImageView into your code with:\n\n imageview.setImageDrawable(new ExampleDrawable());\n\n![diagram](https://raw.githubusercontent.com/StanKocken/SVG2Drawable/master/svg_to_drawable.png)\n\n## License\n\n* [Apache 2.0](http://www.apache.org/licenses/LICENSE-2.0.html)\n\n## Contributing\n\nIf you found a SVG with a problem, you can open an issue.
