Abstract: The present invention relates to an automatic generation method for an Android application micro-service driven by an application scenario. The automatic generation method comprises the following steps: S1: reconstructing a software architecture when an application runs based on application interface information; S2: executing an objective function for many times, and recording the method calling sequence of the objective function to form calling instances of multiple objective function based on the runtime model; S3: analyzing the obtained calling instances to acquire a service module of the micro-service with the objective function; and S4: thereupon giving an user input, and executing the service module of the micro-service to obtain a result identical to the original function.
