1. Start the Android init process Start with Linux. Linux is loaded into the memory by bootloader and starts to run. After the Linux runtime environment is initialized, Mount ramdisk. img root file system image, run the init program, which is also the first user program in Linux, and its pid is 1. The following article describes how to start the init process. Ii

of log whether we write or the system can be monitored to hear wow ka ~ ~ Finally use toast to show the content. @Override public Void Run () { Process mlogcatproc = null; BufferedReader reader = null; try { //Get Logcat log information Mlogcatproc = Runtime.getruntime (). EXEC (new string[] {"Logcat", "Mytest:i *:s"}); reader = new BufferedReader (New InputStreamReader (Mlogcatproc.getinputstream ())); String Line; while (line = R

Significance: Because each application process has its own independent process space, on the Android platform, a process usually does not access the memory space of another process, and we often need to boast process passing obje

Android Process Communication --- Service Manager (1), android --- service The Bind mechanism consists of four parts. Bind driver, Client, ServiceManager Service 1. Bind is actually a linux-based driver for Memory Sharing. The bind driver is biased towards the kernel, and the content of the bind mechanism is very large, so we will skip this part temporarily. 2.

The process of software installation under Android:1: Copy xxx.apk to/data/app/xxx-1.apk2.

Typical drawing process for 1.1.1 applications We know that Bufferqueue has up to 32 bufferslot, so what is the purpose of this design? One possible reason is to improve graphics rendering speed. Because if there are only two buffers, imagine that when the output efficiency of the application producer is greater than the processing speed of the consumer, it will soon dequeue the buffer and be in the waiting state, causing unnecessary trouble. Of cour

Phonewindow, the instantiation of the Phonewindow need a window, only through the WindowManager can be completed, the concrete implementation of the window class is located in Windowmanagerservice, The interaction of WindowManager and Windowmanagerservice is an IPC process. All of the views in Android are rendered through windows, and their views are actually attached to Windows, whether activity,dialog or

Android 5.0 kernel and source code learning (2)-source code download and system startup process analysis, android5.0 I,AndroidSource code download The last time I briefly introduced the hierarchical structure of the Android system, I started to figure it out-download the source code and analyze the source code! So where is the

In the previous section, we explained the local service. This section mainly describes remote service, which involves aidl. Okay, old rules. Let's start with the basic knowledge: I. Basic Knowledge Role of aidl On the Android platform, each application Program All apps are running in their own process space. Generally, one process cannot access the memory

These are necessary for running the kernel, and in order to achieve a specific target, the bootstrapper can set the kernel based on configuration parameters or input data.Android bootloader can be \bootable\bootloader\legacy\usbloader found in.The traditional loader contains a file that needs to be explained here: Init.s Initialize the stack, clear 0 BBS segment, call MAIN.C's _main () function; MAIN.C Initialize the hardware (alarm, motherboard, keyboar

In the previous article, we analyzed the connection process between Android applications and SurfaceFlinger services. After the Android Application successfully connects to the SurfaceFlinger service, an anonymous shared memory is required to share its UI metadata with the SurfaceFlinger service so that the SurfaceFlinger service can correctly create and render t

This article illustrates the detailed analysis of the process steps of the micro-letter SDK sharing function of Android programming. Share to everyone for your reference, specific as follows: I've already analyzed how to share micro-information with official demos. Here I will no longer say, which about in their own application sharing is very simple, the author is also after a lot of toss to get success,
