Description
Technical Field
The application relates to the technical field of dual-system terminals, in particular to an improved method and terminal for dual-system terminal initialization attribute synchronization.
Background
The Android dual-system terminal comprises a working system and a living system, and can provide various scenes for using the terminal for users. The user data are isolated from each other in the Virtual Phone Space (VP) domain and the Root Name Space (rootns) domain, and have no influence on each other, thus having higher security and reliability.
The attribute service is an important component of the Android system, and provides important process interaction service for related services. The attribute service of the dual system adopts a mode of inter-domain communication to synchronize between the VP domain and the rootns domain.
The existing Android dual-system terminal performs attribute synchronization through inter-domain communication: the VP domain monitors attribute nodes in the rootns through the process, and if the attribute in the rootns domain changes, the latest attribute value is notified to the VP domain.
When the terminal is started and initialized, the condition that the attribute nodes are written in the rootns domain but the VP domain is not started exists. In this case, when the monitoring process of the VP domain starts, the attribute value of the attribute node of the rootns domain is already up to date, and the VP domain is not notified any more, so that the problem that the attribute of the VP domain and the corresponding attribute of the rootns domain are inconsistent is caused.
The inconsistent attribute data may cause unreliable attribute service of the Android dual-system terminal, and further cause that the terminal cannot be used normally, for example: unable to make a call, unable to log on the internet, etc.

FIG. 1 is a schematic flow chart of an existing initialization method of a dual-system terminal, in the flow chart, a VP domain monitors attribute nodes in rootns through an attribute service process, and if attributes in the rootns domain change, the latest attribute value is notified to the VP domain; similarly, the rootns domain monitors attribute nodes in the VP domain through an attribute service process, and if the attribute in the VP domain changes, the latest attribute value is notified to the rootns domain.
In order to solve the problem that the attribute service of the existing dual-system terminal is unreliable, the initialized attribute synchronization process is split, so that the condition that the whole service is influenced by primary synchronization failure is avoided. After the VP domain starts, the attribute service process of the rootns domain is notified, and then the rootns domain resynchronizes the attributes required by the VP domain.

1) And respectively carrying out an initialization flow by the rootns domain and the VP domain.
2) After the rootns domain completes initialization, an attribute synchronization operation is initiated. At this time, the rootns domain does not care whether the initialization of the VP domain is complete.
3) After the VP domain finishes initialization, the rootns domain is informed of the completion of startup, and meanwhile, the attribute list concerned by the VP domain is sent to the rootns domain.
4) After the rootns domain receives the notification of completion of initialization of the VP domain, the attribute in the attribute list concerned by the VP domain is synchronized to the VP domain, and the VP domain reads the attribute list acquired from the rootns domain, so that the reliability of the attribute synchronization content of the rootns domain and the VP domain is ensured.
