![]() ![]() Use this action in an intent with startActivity() when you have some information that an activity can show to the user, such as a photo to view in a gallery app, or an address to view in a map app. If you need to start a specific component in your app, you should specify the component name.Īction :- A string that specifies the generic action to perform (such as view or pick ). Without a component name, the intent is implicit and the system decides which component should receive the intent based on the other intent information (such as the action, data, and category-described below). This is optional, but it's the critical piece of information that makes an intent explicit, meaning that the intent should be delivered only to the app component defined by the component name. Implicit intents do not name a specific component to perform a particular action, but instead it declares a general action to be performed, which allows any component, even from another app to handle it.Įxample :- To create an implicit intent you need to add the following component to the intent. For example, you can start a new activity in response to a user action or start a service to download a file in the background.Įxample :- Intent intent = new Intent( this, MyActivity. You generally use an explicit intent to start a new component in your own app, because you know which exact activity or service you want to start. When you explicitly define which Android component should be opened on some user action, then you use explicit intents. Starting a service :- like startService(), bindService().ĭelivering a broadcast :- like sendBroadcast(), sendOrderedBroadcast(). Starting an activity :- like startActivity(), startActivityForResult(). Although intents facilitate communication between components in several ways, there are three fundamental use cases: What is intent in Android ? An Intent is a messaging object you can use to request an action from another app component. ![]()
