&gt; Not sure why Google doesn&#x27;t invest in their own language.<p>Has no one in this branch of the thread ever heard of a little thing called Go?<p>You could also bring up Dart, although Google&#x27;s apparent commitment (and my own interest) in that is far lower.<p>Work IS coming along on being able to write full Android apps entirely in other Google-originated languages.  You might reasonably ask why they&#x27;re not pouring dramatically more resources into accelerating that process.  I don&#x27;t know, but I can only speculate that the enormous scale of the existing Android ecosystem makes it risky to send the wrong signal prematurely.<p>If we&#x27;re looking at a matter of years before full featured Android apps in pure Go is feasible, then you probably wouldn&#x27;t want to talk that up TODAY.  The perception would be that Java on Android is dead, and major new app development for Android would halt.
