本文是关于AIDL的介绍，许多RPC系统考虑使用接口描述语言(IDL)来定义和限制与远程调用相关的格式。安卓也是如此。Android接口描述语言(AIDL)文件帮助开发者定义服务器和客户端一致同意的RPC接口。Android可以考虑从AIDL文件中自动生成代理和存根类，同时将开发人员从底层信息的重新实现中解放出来，以应对binder的本地库(Thiel, 2016)。自动生成的代理和存根类将确保对声明的参数组合进行适当的序列化、发送、接收和反序列化。本篇英国代写文章由英国论文通AssignmentPass辅导网整理，供大家参考阅读。
A number of systems of RPC consider the utilization of Interface Description Language (IDL) for the definition and restriction of format related to a remote invocation. This is the same case in Android. The file of Android Interface Description Language (AIDL) helps the developer in defining the interface of RPC as agreed by the server and the client. Android can consider the automatic generation of proxy and stub classes from the file of AIDL while relieving developers from the reimplementation of low level information for coping up with native libraries of binder (Thiel, 2016). The auto-generated classes of Proxy and Stub will ensure that there is appropriate serializing, sending, receiving and de-serializing for the declared combination of parameters.
The developer has to focus on providing a file of .aidl and there should be implementation of corresponding interface (Traon, 2014). In simple terms, the file of AIDL will serve as the explicit contract of server and client. Such enforcement ends up making an extensible, usage and robust binder framework. The above figure is an appropriate example for AIDL file defining the overall service interface used for the implementation of a queue. The server lays specific emphasis upon de-serializing the borders of Parcel object, processing the basic transaction, and following the report similarly after the client. This helps the purchaser within reaching RPC yet invoking techniques related in conformity with partial remote servers (Visser, 2012). This RPC primarily based about ligature is among the almost established factors in Android because of IPC whilst assisting as such for underpinning in conformity with effective majorities across the system services.
Binder is preferable because of its in-built reference evaluation of object references. In addition, the mechanism of death notification enhances its suitability for the setting of hostile environments. When there is no referencing of binder service through the clients, there is automatic notification provided to the owner for disposing it off. Any user application that runs upon Android is highly restricted to what can be done in the standard way.
