(context, MyService.class));startService(new Intent(context, MyIntentService.class));mainTask();It's supposed to start MyService, start executing the MyService asynchronous task, start Myintentservice and start executing its asynchronous task, and then start the Maintask task, because the first two are asynchronous, So the input result should be three asynchronous tasks cross execution.But what about the two service that started after the Maintask task was executed from the actual input results?
In order to prepare for the interview, the recent review of the content in the form of a blog to save, convenient for future inquiries

Well, start learning, we're talking about the call to activity startactivity.
The startactivity that invokes the activity is actually internally
events are triggered earlier than BOOT_COMPLETED. Therefore, Trojans can first intercept 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 the broadcast is sent, we may be in the descending order. Is th

Activitymanagernative, the binder object of AMS is provided externally in a singleton mode, and Singleton is a single wrapper class that initializes the binder object by the Create method when it first calls its Get method.The role of Checkstartactivityresult is to check the results of initiating activity, which throws an error message when an activity cannot be started correctly.The order in which activity's initiation process passes between Activit

First, we learned that writing a mobile phone program is actually very simple. However, many people may not quite understand how to transfer the program to their mobile phones. If you don't believe it, try it. Whether you use a data cable or infrared Bluetooth, there is no way to get the programs on the computer to run on the mobile phone, nor to get the games on other people's mobile phones to run on their own mobile phones (normal data transmission is acceptable, that is, the program is not ac

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.

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
