These system events are triggered earlier than BOOT_COMPLETED, so Trojans can certainly take precedence over text messages. Based on this confrontation, do we have to fight together with Trojans? Is there a better solution? The answer is yes. The most effective way to promote the development of science and technology is war. In this technological confrontation, it is also the most likely to produce new ideas and solutions.
The basic idea is that after th

How does one Android window be created?Preface
In WmS, a Window is not a Window class, but a View class. After WmS receives a user message, it needs to send the message to the window. In fact, the View class cannot directly accept the transmitted message, but the IWindow class must be used to receive the message. The IWindow class is ViewRoot. W class, each W contains a View variable.
WmS does not care which application the window is. WmS determines which window is active according to certain ru

6.1 Framework framework
Framework defines the functions and interfaces of client and server components. In the following illustration, the example application example generally refers to the example. APK program.
The framework consists of three main parts: Server, client, and Linux driver.
6.1.1 Server
The server mainly contains two important classes: windowmanagerservice (WMS) and activitymanagerservice(AMS ). WMS assign

So the purpose of writing this whole blog is to deepen their knowledge, develop their own communication skills, and we learn together.Well, gossip less, we first solve the problem left behind in the last article, then there is time, I put this interview experience to write a blog, and we encourage each other.Let's look at ServiceManager in this article. Not much of it in the previous article, ServiceManager as a big housekeeper for Android services. It is still necessary for us to take a

In the Android application framework, Activitymanagerservice is a very important component, although the name is Activitymanagerservice, but through the previous blog introduction, we know that the four components are created with AMS to complete , not just the components in the application, but the Android application itself is the AMS startup. The AMS itself is

the zygote service: The zygote process is also called the incubation process, and all processes in the Android world are hatched from this process (fork ()), which is responsible for the creation and initiation of other processes in the application's framework layer.(Frameworks/base/cmds/app_process/app_main.cpp) (The script that launches zygote in Android L is not in the Init.rc file but has a separate init.zygote_xx.rc file to boot to support 64-bit operating systems)I.

This broadcast is not discarded but stored in AMS after it is sent and distributed to the corresponding receiver through AMS (ActivityManagerService, when a new consumer request for AMS registration needs to be dynamically registered, if the consumer can receive this broadcast, AMS will immediately send this
This course solves the problem of how to understand the beginner's mind of Android architecture design and develop a featured product with Android system with deep customization and soft and hard integration capability.The course takes the five core of Android: HAL, Binder, Native service, Android service (and the example of AMs and WMS), the View system as the spindle, a one-time thorough mastery of the essence of Android.The reason why the developme

1. Activity scheduling mechanism
In order to improve user experience, android switches between different applications are basically seamless. They only switch to an activity, so that the activity is displayed on the frontend, And the other application is overwritten on the background, which is invisible. The concept of Activity is equivalent to an interface that interacts with users. Activity scheduling is managed by
