  4. SQLite database provides storage functionalities needed by Android. Being a lightweight database, it enables simpler storage and quicker retrieval of data.
  5. It supports all versions of multimedia files (Audio/Video) and integrates a Microphone, Camera, Accelerometer and speaker for effective management of recording, playback operations.
  6. HTML5 and CSS3 are supported for the development of an intuitive and impressive front end screen.
