Whenever the match found the system starts matching activity ( Activity B) by invoking the onCreate() method. The android system will search for an intent filter that matches the intent in all apps. If you observe the above image Activity A creates an intent with the required action and sends it to an android system using the startActivity() method. For example, by using implicit intents we can request another app to show the location details of the user or etc.įollowing is the pictorial representation of how Implicit intents send a request to the android system to start another activity. * Will return the correct URI for camera and gallery image.In android, Implicit Intents won’t specify any name of the component to start instead, it declare an action to perform and it allows a component from other apps to handle it.
