Design Patterns for Multimedia Mobile Applications

This paper presents a Multimedia Mobile Framework, MMF, to provide mobile applications with flexibility and reusability. The proposed framework integrates fundamental design patterns (GoF), visualization patterns, and sound patterns. The fundamental design patterns include factory method, composite, state, and flyweight after adapting them for Android environment. The visualization patterns are modified and adapted to match MMF. Eventually, the sound patterns to convert from text to speech and vice versa are introduced as new patterns for mobile applications. In all stages, the Android Activity class is employed throughout MMF patterns. To emphasize the significance of MMF, it has been relied upon to develop a multimedia editor for M-Learning applications running on Android platform. In addition, specific quality metrics were selected and the performance of such pattern based editor is quantitatively compared with that of traditionally developed one
