Intent is an important way to interact with components in an Android program, not only to indicate what actions the current component wants to perform, but also to pass data between different components.-----------------------------------------------Show Intent------------------------------------------------Intent has multiple overloads for constructor functions,

1. To solve this problem, you must first understand what is implicit (hidden) intent and what is explicit (explicit) intent.
Explicit intent explicitly specifies the acitivity to be startedFor example, the following Java code:Intent intent = new intent (this, B. Class)

Requirements for this chapter: first, let the app poll for new results and notify the user when something is discovered, even if the app hasn't been opened since the user restarted the device. Second, ensure that users do not notice new results when they use the app.1.

Activity switching is generally implemented through intent. Intent is the method for an activity to reach another activity. It describes the start point (current activity) and the end point (target activity ). A simple intent implementation is as follows:

With intent, your program can express some kind of request or intention to Android, and Android will select the appropriate component to complete the request based on the intended content. For example, if an activity wants to open a Web browser to vi

First, let's briefly talk about the mechanism of alarmmanager: Global timer (also called alarm clock), which broadcasts a specified intent for us at a specific time in two forms:
1. execute an operation when the specified time arrives. If you have set an alarm time, when the time arrives, alarmmanager broadcasts a preset intent for us, use this intent to perform
Intent, also known as intent, is a run-time binding mechanism that links two different components (activity, Service, Broadcastreceiver) in the process of running a program. By intent, the program can express some kind of request or intention to Android, and Android will choose the appropriate component to request according to the content of intention.

When we started out, we often suffered from problems that were originally easy to solve, and we often spent a lot of time.I tried my best to find a solution and finally realized that it was so simple. This was caused by the English world.Intent plays a significant role in Android application development.There is already a lot of information on the Internet, and it is no longer cumbersome here. I like to go straight. I can see many links on the Internet.So much information about

The role of 1.Intent for Android appsIt can be broadly divided into two functions:① packaged Android applications need to start the "intent" of a component② acts as a medium for communication between application components, encapsulates the data that needs to be exchanged into bundle objects, and then uses intent to carry the bundle object2.
Intent is a runtime binding (Run-time binding) mechanism that connects two different components during a program's run. With intent, your program can express some kind of request or intention to Android, and Android will select the appropriate component to complete the request based on the intended content. For example, if an activity wants to open a Web browser to view the contents of a Web page, then the
1. What is intent?
Intent Chinese meaning is the purpose. In Android, it also means "purpose. This is where we are going. Intent is needed to go from this activity to another activity.
ExampleCodeI:

In an Android application, it's made up of four components, and these four components refer to the "Android apps". And these four components are independent, they can call each other, coordinate their work, and eventually make up a real Android application.
The communication between these components is mainly done by intent assistance.
Intent is responsible for the operation of the application of the acti
