Cross-process communication method and device based on Android platform

The invention relates to a cross-process communication method and device based on an Android platform. The method comprises the following steps: a first unified method in a first unified access layer of a first process makes response to a calling instruction of an arbitrary original cross-process method sent by a business layer to generate a cross-process calling request, and sends the cross-process calling request to a second process corresponding to a target original cross-process method requested for calling; a second unified method in a second unified access layer of the second process obtains an identifier and an entry parameter of the target original cross-process method according to the request; the second unified method determines the corresponding target original cross-process method according to the identifier and the entry parameter of the target original cross-process method, obtains called data according to the target original cross-process method, and returns the called data to the first unified
