Android Security Alert: Another app on your phone may be trying to...

Using the SDK in a debug build in Android emulator, dropbox.AuthActivity errors out with a Security Alert "There might be more than one app trying to handle....".

I see that it is very similar to : https://github.com/dropbox/dropbox-sdk-java/issues/153 and the error is https://github.com/dropbox/dropbox-sdk-java/blob/5f47303107da2813f696b520ce976b73d0ba7847/src/main/java/com/dropbox/core/android/AuthActivity.java#L289

1. My app is the only non-default app in the emulator.
2. I have verified that there are no multiple declarations of dropbox.AuthActivity in AndroidManifest files.
3. Have tried uninstalling and re-installing the debug build multiple times.

Any idea what's going on?
