Unlocking Android: Chapter 1 confusion.

[Devender Thareja]

Dear Authors,

I was going through the free chapter of your book. I found figure 1.1 and figure 1.3 contradicting. Here is how:
Figure 1.3 is telling that Android Runtime and all other libraries depend on Linux kernel and Linux kernel envelops rest of Android components as its a lower level component.
Figure 1.1 on the other hands show that Android software environment encapsulate the Linux Kernel.

Could you please clarify what is the real case here?

Thanks.

Good question.

Android applications run within an instance of the Dalvik VM. The vm itself runs within a Linux process.
