If you observe above code snippet the activity “ MainActivity” will act as an entry point for our app because we defined an activity using MAIN action and LAUNCHER category attributes in intent filters ().

Intent Filter in Manifest Fileįollowing is the code snippet of defining an activity with Intent Filter ( ) in the Android Manifest file ( AndroidManifest.xml) like as shown below. It defines the type of data to be accepted and by using one or more attributes we can specify various aspects of the data URI (scheme, host, port, path) and MIME type. It defines the name of an intent category to be accepted and it must be the literal string value of an action, not the class constant. It defines the name of an intended action to be accepted and it must be a literal string value of an action, not the class constant. Generally, the Intent Filters () whatever we define in the manifest file can be nested in the corresponding app components and we can specify the type of intents to accept using these three elements. In case if we create Intent Filter for an activity, there is a possibility for other apps to start our activity by sending a certain type of intent otherwise the activity can be started only by an explicit intent.

In android, Intent Filter is an expression in the app’s manifest file ( ActivityMainfest.xml) and it is used to specify the type of intents that the component would like to receive.
