Hi, I'm not sure what type of device you are working on. As a result, implementing it as an input device may not be the best choice. Anyway, we may solve the problem by treating it as a generic character device driver. Below is one of the solutions for your reference.
First, you may need to implement a Service for the event in Android Application (Framework) layer. Upon receiving the event, the Service will be able to notify the user through the Notification Manager. For the Service to receive the event from the device, through the help of native code (by way of JNI), the Service may poll (with poll(), read(), or ioctl(), etc.) the event through the device file (or sysfs) of the device driver that you implement. (Of course, you need to do this in a thread in the Service.) In the device driver, you can implement the poll() (or read(), ioctl()...) file operations so as to wait the event of the IRQ, which when triggered will wake up the blocked task (i.e. the thread of the Service).
