The previous response briefly describes the principle of inter-process transfer of class objects. before talking about parcel, we should first talk about something: ibinder.What is ibinder? First, you must understand that android remote calls (cross-process calls) are implemented through ibinder. The following is a translation of Android development documentation.Ibinder is the basic interface of remote objects and is the core part of the lightweight

Use of the Parcelable interface in Android, androidparcelable Serialization is very common during development. For example, you want to save the object to a local disk or transmit it over the network. There are two methods to implement serialization: one is to implement the Serializable interface, and the other is to implement Parcelable. Differences between Serializable and Parcelable 1. Serializable is the interface provided by JDK, while Parcelable is provided by Android SDK. 2. Serializable

Android serialization object interface Parcelable usage method, androidparcelable What is Parcelable? Parcelable defines the interfaces for writing data to Parcel and reading data from Parcel. An object (represented by a class). To encapsulate it in a message, you must implement this interface to implement this interface, this entity becomes "packable. Parcelable passed object Android serialization objects

particular, the attribute value of android: name in the tag is the ID of the service to be referenced by the client, that is, the parameter value of the Intent class.3. Data Types supported by AIDL: 1) Java simple type (int, char, boolean, etc ). Import is not required. 2) String and CharSequence; no need to import 3) List and Map. However, the element types of List and Map objects must be the data types supported by AIDL. You do not need to import 4) the API automatically generated by AIDL. Re

four steps to implement Parcelable: 1) implements Parcelable2) rewrite the writeToParcel method to serialize your object into a Parcel object, that is, write the data of the class to the external provided Parcel, and package the data to be transferred to the Parcel container for storage, to get data from the Parcel co
