ACTION_DIAL: This is used to display a Dialer to the users.ACTION_MAIN: This is an initial activity of a task.ACTION_EDIT: This is to edit and make changes in the data that is visible to the users.ACTION_CALL: This is for initiating calls from the user’s device.Let’s see a few actions that an intent object stores: Now, these actions directly target Activities, Services or Broadcast Receivers. ActionĪction defines the general task that is to be performed on components. If we want to read the component name, we can read it using the getComponent() method. To set the component name, we use one of the following three methods : At times, we forget to mention the component name, in such cases, the Android system decides it based on the other characters. Using component names, the system delivers an intent to a particular application component. The intent object holds the name of the component of the Android application.
Now we’ll see these things in detail one by one. An Intent object basically contains the information to determine the component to start and the actions for them.Ĭome let’s see what all information an Intent Object contains within.Īny Intent object contains the following six things : Intent objects are nothing, but a lot of information wrapped together. Passing the Intent object in ndBroadcast(), sends messages to broadcast receivers. We can also send a required request to an existing service. Starting a ServiceĪn Intent object is passed to the content.startService() method, to start a Service. When an intent object is passed to startActivity(), it starts a new activity or an existing one. Starting an ActivityĪn Activity starts/performs a task when we pass the Intent object to the content. Intent performs the following three tasks mainly: 1. These messages allow application components to request required functionalities from other components of the application. In other words, we can understand them as asynchronous messages. Intent in Android enables communication between components of the same as well as different applications. Now, for their activation, we use messages known as Intents.
