Abstract

The embodiment of the invention discloses an inter-application data state synchronization method and device and a computer storage medium. The method comprises the following steps: establishing a mapping relationship between an anonymous shared memory and a first application according to a calling instruction from the first application; sending a first application data state change notification toa second application establishing a mapping relationship with the anonymous shared memory according to the change of the current data state of the first application, so that the second application knows the data state of the first application; wherein synchronization of the data state can be realized between the applications which establish the mapping relationship with the anonymous shared memory. According to the embodiment of the invention, the synchronization of the data state between the applications can be realized, the synchronization mode is flexible, and the efficiency is high.

Description

technical field [0001] The present invention relates to the technical field of communications, and more specifically, to a method, device and computer storage medium for synchronizing data states between applications. Background technique [0002] As the development of Android applications becomes more and more mature, there are more and more scenarios that require continuous communication and interaction between multiple applications. For example, applications need to synchronize a certain state at the same time, but because of the memory isolation mechanism between Android applications, So it is very troublesome to synchronize a certain state at the same time. [0003] Usually, cross-process communication between Android applications is packaged by the system. Only system service applications can share data status with non-system service applications. Non-system service applications generally use contentprovider or inter-application broadcast to achieve communication to sh...
