MainActivity has leaked ServiceConnection when press Back exit Wear app

[huytower]

Hello,

I got the exception as title in above, since I :

• created new project
• apply library in pubspec.yaml file
• create Container widget (empty widget)
• run project
• application open as usual
• press Exit
• the exception in below, has appeared

Please help me check to avoid this exception,
Thanks,

p/s : I did not add anything in Manifest.xml file and build.gradle file (in folder /android)
