1310143 - Use more vector drawables for simple images / icons to reduce APK size

Status: RESOLVED INCOMPLETE

(Firefox for Android Graveyard :: Theme and Visual Design, defect, P5)

Description

[Sebastian Kaspari (:sebastian; :pocmo)]

For Activity Stream we started to add icons as vector drawables (See bug 1309821, bug 1300144, bug 1308525). Those are just tiny XML snippets and much smaller than PNG files in various densities.

We could replace some of the existing icons (or simple images) with vector drawables and reduce the APK size. Android does not support the full spectrum of SVG and we rely on the support library to backport the implementation to older Android versions. Therefore it might not be possible to convert all icons.

FWIW I'm currently looking into some replacements in Bug 1312114.

I'd strongly recommend testing and debugging replacements on Android 4 devices: VectorDrawable's can't be used everywhere by default (e.g. as compoundDrawable's for a TextView don't work, but you can load the drawable from AppCompatDrawableManager, and then set it on a TextView), so some code might have to be rewritten for VectorDrawable's to be used. Some such patches are likely to land in Bug 1312114.
