It is also called Wifi file transfer or wireless file management. Once system Services up and running in memory, Android has completed boot process, At this time “ACTION_BOOT_COMPLETED” standard broadcast action will fire.A powerful application allows you to run FTP Server on your phone and help your friend or you to access/share files over the Internet. This thread will start the remaining services in the system according to the necessary start order.Įach service is running in a separate Dalvik thread in the SystemServer. After setting up the native services it creates the server thread. Then the native init method that will setup native services called. The first thing that happens is that the server will load a native library called android_servers that provides interfaces to native functionalities. The System server is the core of the Android system. System Servers: After zygote preloads all necessary Java Classes and resources, it starts System Server.It enables code sharing across the Dalvik VM which helps in the achievement of minimal startup time. This makes the process of creating a VM and load resources pretty efficiently. When this happens to Zygote, it creates an exact and clean new Dalvik VM as a thread, preloaded with all necessary classes and resources that any App will need. It replicates itself in another memory space. When a process is a fork, it creates a clone to itself. Once it happens, it triggers a fork() call. Zygote receives a request to launch an App through/dev/socket/zygote. When app_process launces Zygote, it first creates the Dalvik VM and then calls Zygote’s main() method. ![]() Zygote and Dalvik VM: The Zygote is a VM process that starts as the system boots.The init process is what will set up all native services and this is similar to a regular Linux system boot. The init.rc is responsible for the initial set up of the system. Mounts directories like /sys, /dev or/proc.Init: Init is the very first process or we can say that it is the grandfather of all the processes.When kernel finish system setup first thing it looks for “init” in system files and launch root process or first process of a system. A Kernel is the lowest level of easily replaceable software that interfaces with the hardware in our device. Kernel: Once kernel boots, it starts setup cache, protected memory, scheduling, loads drivers, starts kernel daemons, mounts root file system, initializing Input/Output, starts interrupts, initializes process table.The BootLoader executes in 2 Stages:Ī) In the first stage, it detects external RAM and loads a program which helps in the second stage.ī) In the second stage, the bootloader setups the network, memory etc which requires to run Kernel. The bootloader is a code that is executed before any Operating System starts to run. A Bootloader is a place where manufacturers put their locks and restrictions. BootLoader: Bootloaders is a low-level code contains the instructions that tell a device how to start up and find the system kernel.Boot ROM loads the BootLoader into RAM and starts executing. This means that whenever we press the power button, the Boot ROM code starts executing from a pre-defined location which is hardwired in ROM. Boot ROM: This Step is known as power ON and system startup.ISRO CS Syllabus for Scientist/Engineer ExamĪndroid Boot Process includes the following six steps:.ISRO CS Original Papers and Official Keys.GATE CS Original Papers and Official Keys.
