Features of componentsFor Android, the four components of activity, service, ContentProvider and service, cannot have setters and getter, and cannot add interfaces to components. The reason is that the components are called to the system framework, the developer can only implement its specified callback interface, component creation and destruction are controlled by the system framework, developers can not

Android also has many built-in security functions in the operating system, greatly reducing the security issues and frequency of applications. Some security features help developers build secure applications, including:

We know that every RDBMS has its own characteristics in SQL. So today, let's take a look at what features Oracle has. Meaning.
