SeriesGuide currently unavailable in Google Play
SeriesGuide has been removed from the Play Store by Google based on a violation of the Google Play Content Policy.
I have submitted an appeal and hope to hear from the Google Play Team soon.
I'm sorry for any inconvenience this may cause.
Update: for those asking, the latest APK is still available on GitHub https://github.com/UweTrottmann/SeriesGuide/releases
