First, the start time of ContentProvider applicationContentProvider can provide data to multiple processes, such as ContentProvider implementation in application A, the process of a is not started, and another application (process) B launches application A When the ContentProvider is used.When you call Contentresolver's query, the binder agent Icontentprovider in process B of ContentProvider in A is obtained first.The implementation of Acquireunstableprovider is in class Applicationcontentresolv

ActivityManagerService boot up sequence analysis,ActivityManagerService (AMS) is the core service in the android system. It is mainly responsible for the startup, switching, scheduling, and application management and scheduling of four major components, its responsibilities are similar to the process management and scheduling modules in the operating system.The call track of ActivityManagerService in system server is divided into the following four pa

If the default value is provided, we do not need to explicitly pass the value to the constructor.Copy codeThe Code is as follows:> Class program roomc1c (object ):'Hotel room rate calculate'Def _ init _ (self, rt, sales = 0.085, rm = 0.1 ):'''Specify the default arguments:Sales tax = 8.5% and room tax = 10% '''Self. salesTax = salesSelf. roomTax

(i) PrefaceIn a previous post about AMS, mention a little bit of tabactivity. At that time said it is more special there is no following, today, re-send a post, to discuss with you about tabactivity.Make a hypothesis: for example, our outermost activity is mainactivity, the first tab is Firstactivty, the Second tab is secondactivity.I believe everyone has used tabactivity, it is a special activity, where is its special place? The following points are

We know that the activity in AMs in the form of Activityrecord,task in AMs in the form of Taskrecord, process in AMS management form is Processrecord.Let's look at the previous version of 4.4:Prior to android4.4, the AMS management Task was to manage all the activity through a ArrayList mhistory:The conclusions are as

3 activity design framework 3.1 activity outside the feature space Let's take a look at the activity in the external feature space that Android app developers are exposed to. For AMS, this activity is a customer service activity. When creating an Android Application, the app programmer builds the sub-class of the activity to display the feature space outside andoid. The following simple example describes how to create an activity. Demoactivity exten

Stack structure changes of Android 4.4 We know that the form of activity in AMS is ActivityRecord, the form of task in AMS is TaskRecord, and the management form of process in AMS is ProcessRecord. Let's take a look at versions earlier than 4.4:In versions earlier than Android 4.4, the AMS management Task manages all t

1. What is ANR? ANR (application not responding) means that the application has no response. 2. What is the cause of ANR? The root cause of ANR is that the app blocks the UI thread. In the Android system, each app has only one UI thread, which is generated by default when the app is created. The UI thread initializes a message loop by default to process UI messages, ANR often times out when processing UI messages. What are the sources of the UI message? There are two main sources: 2.1 callba

performs other startup items according to the inittable file-->Thus, when the kernel is initialized, a fairly important ancestor process is initiated, that is, the init process, where all processes in Linux are directly or indirectly forked by the INIT process. For Android, the previous process is the same:(1) When the init process is created, it will fork out a zygote process, which is the parent process of all Java processes. We know that Linux is based on C, and Android is Java-based (and of

You can use the iwconfig command to verify this. [Root @ sfo ~] # Iwconfig Wlan0 IEEE 802.11 abgn ESSID: "sandernet" Mode: ad-hoc Freq

implementation of the start activity is done by the Activitymanagernative.getdefault (). StartActivity method. This method returns Activitymanagerservice. Activitymanagerservice (AMS) inherits from Activitymanagernative, And Activitymanagernative inherits from Binder and implements the binder interface of Iactivitymanager, so AMS is also a binder.
