CWAC-Presentation v0.5.1 has just been released. This upgrades to the Android Gradle Plugin 3.0.1 and related version of Gradle. It also updates the
demoService app to use a foreground service, as that clears up issues when the process is terminated (e.g., swiping the task off the overview screen on some devices).
If you encounter any problems, feel free to ask a question here, or on Stack Overflow, if the question has not already been asked.
