It is a universal mechanism of passing data between processes. With help of the intents one can start services or activities, invoke broadcast receivers and so on.

It is similar to android inter app communication serialization of an object, but much faster on android. Bundle can be read from intent via the getExtras method. It allows not simply sending messages to services but directly invoking methods on them. All the answers are good and concise in this post. But i would like to light upon which IPC mechanism should i use. First of all IPC means Inter Process communication where two applications or processes will communicate with each other by passing some data between them, android inter app communication.

Parcel is a sort of light weight serialization by using shared memory concept. Serialization is very heavy to use in embedded devices, communication will be very slow.

Binders uses Parcels to make IPC very fast. Binders internally uses Shared memory concept which uses less memory while sharing data between two processes.

Bottom Line: Binders uses less memory, and quite fast as it uses parcels. Serialization is very heavy, takes time to send and receive data, and also it takes more memory compared to binders. Note: To pass data between activities, android inter app communication, services, and receivers use only Bundles. Don't go for either serialization or binders.

What Web Can Do Today. Inter-App Communication. There were several attempts to establish the universal, multi-platform, asynchronous way of data exchange from the Web applications to native apps or another Web apps and up to date no standardized solution was concieved. It was conceptually based on Android Intents system. The apps. Android Inter-Process Communication. At the simplest level there are two different ways for apps to interact on Android: via Intents, passing data from one application to another; and through Services, where one application provides functionality for others to use. An Android app typically has several activities. Each activity displays a user interface that allows the user to perform a specific task (such as view a map or take a photo). To take the user from one activity to another, your app must use an Intent .
