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 following is the flow of source application to the content provider in Query Target application, where only the content provider is started.The picture above are the flow chart for how Content Providers started(1) Source APP Inform AMS to query the content provider with URL, in Blue;(2) AMS searched all registered content providers, once not found, it'll 1stStart the application whose androidmanifest ho

implementation process points are summarized as follows:1. The broadcast recipient broadcastreceiver through the binder mechanism to the AMS (Activity Manager Service) registration;2. The broadcasting sender transmits the broadcast to AMS through the binder mechanism;3.AMS finds the broadcastreceiver that meet the appropriate conditions (intentfilter/permission,

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. Zygote create Apprunti

broadcast 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

Activity hijacking and anti-hijacking (1) 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

Mycat1.5 ~ A bug in 1.6, mycat1.5 ~ 1.6bug The following statement runs normally in a single mysql database: SELECT * FROM device WHERE devicetype = 'ams. Monitoring.

communication between different processes, according to the actual business use of broadcasting mechanism will be very appropriate.Third, the concrete implementation of the Broadcastreceiver process is as follows:1, the broadcast recipient broadcastreceiver through the binder mechanism to the AMS (Activity Manager Service) registration;2, the broadcast sender through the binder mechanism to send the broadcast to
