Disclosed are an Android-based page launching method and system, a storage medium and an electronic device, relating to the field of Android client componentization. The steps of the method are: providing a message event bus between a component and an application module; when the component needs to launch a page in the application module, the component acquiring page launching information, packaging the page launching information as page launching data and then transmitting the page launching data to the application module via the message event bus; and the application module parsing the page launching data to obtain the page launching information, and via a start function, launching a page corresponding to the page launching information. By means of the present invention, a page in an application module can be launched by means of an Android client component without changing a service logic of the page. The present invention can achieve the purpose of launching a page by a component by means of launching a page by an application module, thereby ensuring stable performance of the page and the subsequent user experience.
