HERE LIES THE MAGIC

Okay, quick rundown of how this app came to be.

• I heard about Google's new Chromecast Screen Mirroring feature and its limited availability.
• I decompiled the new Chromecast apk to see what I could find.
• I ran a grep -r mirror | grep string | grep mirror (I only run grep mirror the second time for color control)
• That spat out a few strings about mirroring!
• Oddly enough, a week or two before, @zhuowei taught me about modifying Google Applications by messing with the Google Play Services Database.
• So, just to try, I pulled out my old Kindle Fire HD 7" (2012) and tested it.
• Luckily enough, it worked!
• I then copied and pasted and changed some code from #DebugAllTheThings and voila! You have an app that can enable/disable mirroring on the device that it's running on!
• At first, it would require a reboot, but I found that by force-closing com.google.android.gsf, com.google.android.gms, and com.google.android.apps.chromecast.app, the database's changes were recongized without needing a reboot.
