    Android Os

    Abstract Mobile devices have seen an extensive amount of development in recent years, but one question is still looming and nobody seems to have the answer: what is ’standard’ for the mobile platform? Many companies have already written their own in-house operating systems for the devices they manufacture such as Symbian or iPhone OS. However, with the existence of so many closed-source operating systems, no rational company would want to disclose their secrets and lose their edge on the competition. This presents a problem where software developers can’t write their code to be generalized. The Android team hopes to solve this on two levels. Firstly, it seeks to arrive at a common open-source operating system that any mobile device can run on. Secondly, it seeks to make developing applications for these mobile phones more general and hardware-agnostic.…
