The mobile applications have enjoyed explosive growth these last years. Taking advantage from these existing softwares, the constituent software bricks to compose such mobile application can take different implementation forms and manipulate heterogeneous data by dint of user's requirements or its execution context. However, the mobile software developer confronts difficulty to compose already existing software entities because of their heterogeneity. An emerging need is then to have a new modelling space to support the development of heterogeneous mobile applications. In view of this fact, this paper discusses the proposal of a multi-paradigm for representing mobile applications based-on heterogeneous conceptual bricks including their architectural conception and the specification of the necessary adaptation mediators. The proposed paradigm aims to deal with the heterogeneity presented by the constituent conceptual bricks and the execution environment of the final product. A conceptual description of a mobile application baptised ShopReview is presented to show the usability of the proposed paradigm.
