Process communication is the mechanism by which application processes Exchange data and service objects through the operating system. Traditional interprocess communication (IPC) of the Linux operating system is available in several ways, such as pipelines, command pipelines, semaphores, shared memory, Message Queuing, and network and UNIX sockets. While in theory Android systems can still use traditional Linux process communication mechanisms, in pra

Generally reducing access to personal information can reduce the security risk of this piece.If you have to access sensitive data, evaluate whether it is necessary to transfer the information to the server, or whether these operations can be performed only on the client.

Service is an application component that can run in the background for a long time without interacting with users. Other components can enable the service. After the service is enabled, the user can switch to another application in time. In addition, components can be bound to the service for interaction, and cross-process interaction (

OverviewAndroid includes an application framework, several application libraries, and a Dalvik-based virtual machine, all of which run on the Linux kernel. By taking advantage of the Linux kernel, Android receives a large number of operating system services, including process and memory management, network stack, driver, hardware abstraction layer, and services r

But the service needs to run independently and wait for the task.Start_redeliver_intentAssuming the system kills the service, it then restarts the service and then the Onstartcommand (), and passes the previous intent.
