It's being a while since I have done Android native dev, Can someone review the PR I sent https://github.com/apache/cordova-android/pull/255
This hit us today at work, we have a complex launch of multiple Cordova Activities to deal with security aspects and crosswalk. It's only in cordova-android@5.1.0 due to the recent changes for saveState and restoreState for plugins It will be great to release a 5.1.1 next week with a couple of other bugs that are already seating in master.
