📖 Seems like in Android 7.0 VectorDrawable was re-implemented to use native rendering.

Restarting application over and over to get necessary numbers Most of the time VectorDrawable goes straight into ImageView. Other tools merge it with inner when possible. svg2android tends to keep useless - ones that draw nothing, i.📖 The maximum instructions count for Lint is 800.ĭo not forget that #apksizematters! Less instructions → less text → less file size.īesides pathData differences, there are some minor deviations as well. More efficient decisions based on the instruction. Operations squashing helps with optimizing drawing performance since the renderer can make v draws a vertical line using the shift, which is 6 - 4 = 2 in our case.L draws a line to the point (x = 4, y = 4) and another one to (x = 4, y = 6).Is the same as L4,4 v2 from Android Studio. Taking separators out of the picture, further changes go to squashingĪnd replacing operations. In other words, M20,4L4,4 from Android Studio is exactly the same as M20 4L4 4 from svg2vector. So commas can be replaced with spaces and vice-versa. The SVG specification does not care about separators, Not the best example since SVGO hadn’t optimized anythingĪnd looks identical to Android Studio. 📖 android:pathData uses the exact same format as d attribute in SVG files. It can be used to teach basic programming concepts It reminds me of the very first programming language This attribute serves as an instructions set in terms It is not surprising, but files produced by different tools are different.Įspecially when it comes to the most important thing - android:pathData. I suspect that these icons were designed with mobile in mindĪnd were pre-optimized for mobile rendering, but that might be completely false.īoth of them are conventionally sized to 24 dp. It is not advisable to use vector images of such size,īut let’s look at it as a push-to-the-limit approach. Image sizes are unconventional - more than 1024 dp.

These are examples of semi-complicated web icons. SVGO (1.0.5) - command line tool, optimizes SVG files.Avocado (1.0.0) - command line tool, optimizes VectorDrawable XML files.Which tool does the job better? Let’s find out! ToolsĬonverters (do optimizations under the hood): The colleges of mine convert SVG images to VectorDrawable viaĪ specific converter and I use Android Studio. Pushing widgets around, changing text and images… Or Not? September 18, 2018Īn average working day of an Android developer involves doing something with UI.
