AndroidStudio emulator "won't run unless you update Google Play Services"

Navigate to settings--> apps in your emulator and then find Google Play Services, check the version number and use it in you build.gradle

Hope this helps

Change the SDK in your emulator to v21 or lower. Physical devices are not effected by this issue.

The reason Android is complaining about an update for Google Play services is related to a known issue in Android emulators for API v22 and up (at this time 23). https://code.google.com/p/android/issues/detail?id=176348

You should try to use the latest version of Play Services in your build script as users are generally forced to have the latest version of this on their device.

I downgrade the SDK to 5.0 from 5.1 and it's work.
