Answer 1

The errors you’re seeing are from the inbuilt email app in Android. It seems to have a leaky ServiceConnection, and you’re seeing some errors because of that in the LogCat. This is completely unrelated to your app, and you can safely ignore it.

In the future, you can try filtering the logcat using your apps process ID so that only messages from your app are shown, and messages like this which may lead to false positives are hidden.
