The v17 device did complain to logcat about some font metadata paths:

android: I/chromium: [INFO:SkFontMgr_android_parser.cpp(595)] [SkFontMgr Android Parser] '/system/etc/fonts.xml' could not be opened
android: I/chromium: [INFO:SkFontMgr_android_parser.cpp(595)] [SkFontMgr Android Parser] '/vendor/etc/fallback_fonts.xml' could not be opened

but seemed to run fine. From adb shell ls, those font files didn't exist on the 4.2.1 device, but these files did:

[~/projects/flutter/flutter/packages/flutter_tools] adb shell ls -l /system/etc/system_fonts.xml
-rw-r--r-- root     root         3418 2012-11-16 16:28 system_fonts.xml
[~/projects/flutter/flutter/packages/flutter_tools] adb shell ls -l /system/etc/fallback_fonts.xml
-rw-r--r-- root     root         4153 2012-11-16 16:28 fallback_fonts.xml

FWIW we state in a few places that we support KitKat and up. Perhaps we should be a bit more specific and state which version numbers and API levels we support: https://source.android.com/source/build-numbers.html

I'll open an issue for the site.

Related to the link mapping versions and api levels, here's one that has usage levels for the various android versions: http://developer.android.com/about/dashboards/index.html.

v15 device I have (ICS)

One of the core Android framework components we use (Choreographer) doesn't exist on ICS. We can write a replacement for it if we need it. Chrome has a replacement that we can use as a model. We should be able to run on even the earliest release of JB.

LGTM

Cool, updated to specify all Jelly Bean versions (android >= v16).

@abarth Hi, you mentioned One of the core Android framework components we use (Choreographer) doesn't exist on ICS. We can write a replacement for it if we need it. Chrome has a replacement that we can use as a model.

I really need to get React-Native (sorry for mentioning competing framework) to work with Android ICS and am trying to make it work with that.

Could you point me to the Choreographer implementation in the chromium source, so I can continue on my humble quest? Thanks!

It looks like they might have removed the code. I'd try digging into the history of https://code.google.com/p/chromium/codesearch#chromium/src/ui/android/java/src/org/chromium/ui/VSyncMonitor.java to see what the code used to do.

@abarth wow fast reply, thanks! Doesn't surprise me they dropped it, since they cancelled android ICS support back in 2015. That's why I wasn't able to find it :) Thanks again!

Update: In case anyone wants this too, ICS compatibillity was removed here: https://chromium.googlesource.com/chromium/src/+/962fc2256d7dd6c8ade0c13b3fbefb4a524b8a4c%5E%21/

I'll check this out tomorrow.
