first parameter in intent android studio

An example for an implicit broadcast would be an action of an incoming SMS message. Because of this behavior, implicit broadcasts do not have a target attribute. You need to do all of this because the Android operating system goes over all the declared intent filters in your manifest and sees if there is a match.

To register for one, you need to use an IntentFilter and declare it in your manifest.

An implicit broadcast is one that does not target your application specifically so it is not exclusive to your application.

A broadcast can either be implicit or explicit. Meaning, that they are invoked when a certain action has occurred that they have been programmed to listen to (I.E., a broadcast).Ī broadcast is simply a message wrapped inside of an Intent object. Backgroundīroadcast receivers are components in your Android application that listen in on broadcast messages(or events) from different outlets: It doesn’t matter if your application is currently running, in the background or not running at all. A broadcast receiver will always get notified of a broadcast, regardless of the status of your application. The solution to this problem is a Broadcast Receiver and it will listen in on changes you tell it to. This implementation is bad for various reasons so we won’t even consider it.

How do you do that? A possible solution would be a service which always checks the internet connection. You want your application to get notified when the internet connection changes.

Let’s say you have an application that depends on a steady internet connection.
