Generally, keeping the AirDroid Cast process running on devices' background is the key to solving the connection problem, such as failing to connect devices, or disconnecting constantly.

Notes：
- Background tasks will consume a device's limited resources, like RAM and battery. So the Android OS system will handle the task killer when memory is low and very deliberately doesn't allow you or app developers to control the background task killer. That's why we can't keep the AirDroid Cast service permanently alive in the background.
