Android's architecture diagram [obsolete source] On top of the Linux kernel, there are the middleware, libraries and APIs written in C, and application software running on an application framework which includes Java-compatible libraries. Development of the Linux kernel continues independently of Android's other source code projects.
Android Runtime (ART) is an application runtime environment used by the Android operating system. Replacing Dalvik , the process virtual machine originally used by Android, ART performs the translation of the application's bytecode into native instructions that are later executed by the device's runtime environment.

Mobile architecture allows maintaining this connection whilst during transit. [1] Each day the number of mobile devices is increasing, mobile architecture is the pieces of technology needed to create a rich, connected user experience. Currently, there is a lack of uniform interoperability plans and implementation.
A Dalvik-powered phone. The relative merits of stack machines versus register-based approaches are a subject of ongoing debate. [16]Generally, stack-based machines must use instructions to load data on the stack and manipulate that data, and, thus, require more instructions than register machines to implement the same high-level code, but the instructions in a register machine must encode the ...
It contains init, which is executed. The Android kernel is a modified version of the Linux kernel. Init does mount the partitions. dm-verity verifies the integrity of the partitions that are specified in the fstab file. dm-verity is a Linux kernel module that was introduced by Google in Android since version 4.4.
Java support While most Android applications are written in Java, there is a Java virtual machine in the platform and Java byte code is not executed. Java classes are compiled into Dalvik executables and run on using Android Runtime or in Dalvik in older versions, a specialized virtual machine designed specifically for Android and optimized for battery-powered mobile devices with limited ...
It is a process because a sequence of steps is prescribed to produce or change the architecture, and/or a design from that architecture, of a hardware system within a set of constraints. It is a discipline because a body of knowledge is used to inform practitioners as to the most effective way to design the system within a set of constraints.
