Using self-defined parcelable objects during an Android aidl RPC/IPC callIn my previous post "Using the Android Interface Definition Language (aidl) to make a Remote Procedure call (RPC) in Andro ID "I ' ve explained the basics on how inter-process communication can is implemented in Android. Now we'll take a look at a
source of this class Androidruntime (click Open link), where the start function has two functions, one is to start the Dalvik VM, The first is to execute the main function of the com.android.internal.os.ZygoteInit, and pass the relevant parameters to realize the zygote initialization work.Let's look at the source code for this Java class (click the Open link) and see what Com.android.internal.os.ZygoteInit is doing.Zygoteinit completed the actual system_server boot, while initializing the zygot
In this paper, we introduce the content of Android to Judge app state by the way of illustration, as follows:
To understand this piece, first of all need to understand some concepts, app,process,task
1.process is the process, the concept of Linux.
2. A generic app has a UID, runs in a process, and if the
messages (see the permission attribute).
When True indicates that receiver can receive messages other than the owning app, and false, only messages sent by the same app component or the same UID app are received. The default value of this property depends on whether the intent filter is declared and, when there is no declaration, the default is flase; when at l
to set the page to set the language type effect. After discovering that a new locale has been set for the current system, not only has its own application language changed, but all of the system's applications have changed. This must be unreasonable. Perhaps you will say, when exiting the app, the big deal again to change the language back. But in Android, the reasons for killing the
Project requirements: 1. Create a system application TestAPP. The application starts a service after it is started. The service provides data interfaces for other applications.
2. Add a method to the acitivity source code and call the TestAPP method in the system application for data interaction.
1. Add the aidl file under the frameworks/base/core/java/android/app
The following section describes how android and javascript call each other. In this way, the UI is much simpler to design, and the UI can also be designed to be cross-platform. Now there are a lot of front-end web app frameworks, such as sencha and jquery mobile. We believe that with the development of web apps in the future, we can also use html to design an int
The context plays a very important role in the development of Android apps, Like starting an activity. You need to use the Context.startactivity method to convert an XML file to a view object, and you need to use the context object, so to speak, if you leave this class, Android is nowhere to go, how much do we know about such a class? 。 I will tell you how I feel, in the beginning to learn the development o
Onresume function is executed, the application is displayed ... In fact, this is an inaccurate statement, because from a system level, an Activity after Oncreate/onstart/onresume these life cycle, just completed the application of some of its own configuration, such as window of some properties of the settings/View tree establishment (Just build, and not show, that is, just call the inflate only). Later Viewrootimpl also calls two times performtraver
