Detailed explanation of IPC using bundle for Android

1、 Bundle introduces IPC

Three of the four components (activity, service and receiver) support the transfer of bundle data in intent. Because bundle implements the Parcelable interface, it can be easily transferred between different processes. Of course, the transmitted data must be able to be serialized, such as basic types, objects that implement the Parcelable interface, objects that implement the serializable interface, and some special objects supported by Android. See the bundle class for details, and you can see all the types it supports. A type not supported by bundle cannot pass data between processes through it.
