Google has announced that Chrome for Android is now open source, the news was announced by Android software engineer Aurimas Liuyikas on Reddit.
The reason that Google has said it is ‘almost entirely open source, is that licensing restrictions for some media codecs, plugins and some Google services stop these being included.
After lots of work by Chrome for Android team and a huge change, Chrome for Android is now almost entirely open-source. It now matches Chrome desktop and you can build a Chromium browser by building chrome_public_apk target.
