What does intention mean in android?

Intent means "intention, plan" in English, which is actually to tell others what your intention means, so the intention in Android is not difficult to understand.

The written explanation is:

Intention mechanism is provided in Android to assist the interaction and communication between applications. Intent is responsible for describing actions, data involved in actions and additional data in an application. Android is responsible for finding corresponding components according to the description of Intent, and passing Intent to the calling component to complete the calling of the component. Intention can be used not only between applications, but also for the interaction between activities/services within applications. Therefore, Intent plays the role of media intermediary here, providing the information of mutual calling of components, and realizing the decoupling of caller and callee.
