When judging database for non-empty, the data of storage are sent to server.
When database non-empty, illustrate the state for occurring offline, therefore, it is necessary to send the data stored in database
To server, and when database is empty, illustrates the state for not occurring offline, therefore, only occurred off-line state
It will start the step of data in database are sent to server, the operating pressure of processor can be mitigated in this way.
It should be noted that the data for having transmitted to server in database can be deleted after being sent
It removes, to save the memory space of memory.
In addition, the method for the present embodiment can also include:
When the size of memory stores data reaches memory storage space size, earliest created data are deleted
Table.
It should be noted that the method for the present embodiment can also include:
It obtains user data and sends demand；
Corresponding data are sent to server according to demand is sent according to data.
For example, can be set to send the data to cloud again when data change or when in a certain range
End, not only can improve the refresh rate of data, and also reduce network uses flow.
