Notes de l'éditeur
- Notes: Architecture diagram
- Notes: In 2.1 and prior, Android applications were running with one hand tied in the back. But in 2.2, AKA Froyo, a JIT just-in-time compiler was added to the VM that translates bytecode to much more efficient machine code much like a C/C++ complier. The performance boost is tremendous. Benchmarks show a 2x - 5x boost. Real life usage shows that the difference is more than just perceivable. Dalvik VM, created by Dan Bornstein. Optimized for low memory requirement and can have multiple instances running efficiently.

- Notes: Overall smartphone market continues to grow. But all other platforms, including iOS see decline in market share while Android posts greater and greater growth rate in the first half of 2010. (2.8% - 9% - 13% in US) Feb: ~ 19 devices (Magic, Hero, Milestone, Nexus One) May: ~ 30 devices (Backflip, Legend, X10i, Desire, Galaxy S) Jun: ~ 36 devices (Evo 4G) Jul: Droid X, etc.
- Notes: HTML5 combined with the likes of Sencha Touch (mobile app framework) could be the future of the majority of mobile app.
