Holy cow! If you write Android apps, you need to look over here right now. You've probably heard of AIDE, a complete development environment that runs on and builds for Android. While it was pretty impressive before, you won't believe what the appfour GmbH team has in store now. Just today, version 2.0 of the Android IDE was pushed to the Play Store with support for building native apps with C/C++, quick previews of XML layouts, and a cleaner and even more Holo-themed interface, along with major enhancements to Git.
These days, it seems like everybody can create basic Java-based applications on any old Android device thanks to tools like Tasker App Factory or any number of IDEs and compilers; but nobody even mentions building high performance native apps and games.
