Android emulator spams logcat with "Service com.android.exchange.ExchangeService has leaked ServiceConnection ... that was originally bound here
Solution 1:
A simpler fix is to disable "Exchange Services" in the emulated device under Settings : Apps : All
(you may need to swipe over to see the "All" tab)
Solution 2:
Nothing helped me until I deleted this current emulator device. After that I have set up a completely new virtual device. My new emulator device doesn't have all these errors. This fixed my problem.
Solution 3:
In my case what worked was turning off the Firewall (I use Windows 8 machine with the latest SDK for Android, 4.2).
Solution 4:
After 60minutes of searching around this error I spotted that I just had an infiniteloop which caused this exchange service spam until app-shutdown. just leaving this here in case anyone else overthinks it
