it's an android emulator that gives you access to the google play stone on a computer if you don't know what it is.
so is it still crashing or was it fixed
If your phone is rooted you can use titanium backup or lucky patcher or one of many backup apps, if not you can try Helium ( https://play.google.com/store/apps/details?id=com.koushikdutta.backup&hl=en ), its pretty good but you need to make an account and use chrome. You can find tutorial here: http://gs5.wonderhowto.com/how-to/back-up-your-android-apps-their-data-without-root-0158767/
Yeah, I usually try to run rituals only when I have few coins. You're not getting both from me! I used AZ Screen Recorder - No Root. Recorded and saved as image with that app. (free app, gotta pay to save as image but you can probably use something else to convert it) https://play.google.com/store/apps/details?id=com.hecorat.screenrecorder.free
