The process sandbox provides an isolation mechanism between untrusted applications, and Shareduserid provides a mechanism for sharing resources for applications that have a trust relationship. However, due to the fact that users themselves install applications that are not trustworthy, Android apps do not have any permissions by default and cannot access protected device APIs and resources. Therefore, the permissions mechanism is the basis of the
to obtain data and service. This is the return to the ancient Client-server model. Client-server-based computing model is widely used in various fields of distributed computing, such as Internet, database access and so on. In embedded smart handheld devices, this client-server approach is ubiquitous in order to provide functionality to application developers in a unified mode. Media playback, audio and video devices, sensor devices (acceleration, azimuth, temperature, light intensity, etc.) are

Sandbox, process, and permission In Linux, a user ID identifies a given user. on Android, a user ID identifies an application. The application is assigned a user ID during installation. The user ID remains unchanged during the lifetime of the application on the device. Permission is about allowing or restricting applications (rather than users) to access device resources. Android uses the sandbox concept to
