Why was Java chosen for Android, instead of something like C++? While I certainly am no expert, I have heard that Java uses quite a lot of memory and I would presume that low memory usage would be quite important on mobile devices. Is there any real advantage to using Java instead of a language like C++ on a mobile device?
This article sheds some light on the situation. The most pertinent link within that article is this. So you've got a massive install base with lots of programmers who know the language and it's widely taught at universities. C++ was dropped from my school's curriculum, Java is still here. Java has Java ME which has a massive install base on other cellphones. The Pantec Ease I have in my pocket right now has a little coffee cup in the corner of the screen. Anyone care to guess what that is?
This answer on Stack Overflow covers it pretty well too.
Summary of SO answer:
Not sure why exactly Java was chosen but it was probably for a number of reasons
Secondly, there is not Java Virtual Machine specified for Android. Instead all Java code is compiled for running on Dalvik, which is a lightweight, optimized VM specifically designed for running in mobile environments. It purportedly enhances battery life and maximizes efficient use of resources.
I'll hazard a guess that Google choose Java for familiarity, if nothing else. Many of Google's projects revolve at least concepts of Java schematics (GWT for example).
Also remember that Android came in a little late to the party. Forcing developers to use C++, a low-level compiling language, would make it harder to generate a 'wow' factor, and if nothing else, Android needed numbers (of apps) and flashiness to get off the ground.
