A development device operating system may simulate a first electronic device operating system. A first electronic device application executed by the simulated first electronic device operating system may generate a command for a second electronic device application executed by the simulated first electronic device operating system. A first electronic device framework of the first electronic device application may process the command for the second electronic device application. The processing may transform the command data for the second electronic device application to a form that is usable by a simulated relay module executed by the simulated first electronic device operating system. The simulation relay module may route the command to the second electronic device application. The development device operating system may display data for the second electronic device application on a simulated second electronic device display. The displayed data may be updated based on the command for the second electronic device.
