Inter-device communication transmission system and method thereof

The present invention discloses an inter-device communication transmission system and a method thereof. The inter-device communication transmission system includes a first-communication platform disposed in a first electronic device and a second-communication platform disposed in a second electronic device. When the first electronic device installs an application, the first-communication selectively transmits the application to the second-communication platform, such that the second-communication platform installs the application automatically. When the second electronic device executes a function of the application, the second-communication platform transmits a command corresponding to the function to the application installed in the first electronic device through the first-communication platform and the command is executed by the application, so as to retrieve a data. The first-communication platform transmits the data to the second-communication platform, and the data is shown by the application installed
