that we need to be aware of, for this we must apply some special settings so that we can finally be informed of those events and happenings. The settings must be applied in such a way that the application is aware of the events and happenings that occur in some operating systems and responds to them appropriately, which is possible by using BroadcastReceiver components.

Here are the things we will learn in this tutorial:

- What is BroadcastReceiver?- How to implement BroadcastReceiver on Android - How to build a BroadcastReceiver - How to BroadcastReceiver- How to register a BroadcastReceiver in the manifest using the static method- How to record BroadcastReceiver in activity using dynamic method- What are the most important events of Android systems?- How to publish different types of messages in Android systems

What is BroadcastReceiver?

In order to be able to say what BroadcastReceiver is, we need to give you some examples. For example, suppose we want to create an application that must be connected to the Internet and is very dependent on the Internet, in this case, if the user is using the application and the application is not connected to the Internet must be Inform the user so that the user is informed that it is not connected to the Internet. In other words, it can be said that not connecting to the Internet must be notified to the user to take the necessary actions.In other examples and situations, consider that the user wants to use an application and using that application requires entering a verification code. Verification codes are sent via messages and users must enter them in the text box of the application after receiving it in order to be able to enter the application and use it. In this case, we should be able to be notified of events that occur in applications and operating systems so that we can apply settings that automatically enter the verification code sent in the text box without entering the user.To do this, we must be aware of the events that occur in the system so that we can finally make these settings, but we can also use BroadcastReceiver.

How to implement BroadcastReceiver on Android

1- We create a new project in Android Studio with the desired name BroadcastReceiver. It should be noted that the name of this project has been chosen arbitrarily in this BroadcastReceiver tutorial, and you can choose other names for this project.2- The activity used in this project must be of Empty Activity type.3- We need to create a BroadcastReceiver.4- It should be noted that in order to be able to create BroadcastReceiver , we must create a new class that inherits from BroadcastReceiver.5- Override the onReceive () method in this class so that we can receive the relevant messages.

Note:

Messages are received in intent format.6- I create a Java class inside the project with the desired name MyReceiver.7- The code that should be included in MyReceiver.java is as follows:
