Damn, that was hard. Android Studio 2.1.2 is really a bitch to tame. I had not used AS for a while, so when I opened it I needed to upgrade, which I did. That is when the pain started. If you are using an older phone than Android v21 Lollipop then you will need add a lower version of gradle 2.10 to work.
The different versions of Android require different versions of gradle. Upgrade your android version and your gradle version will correspond. Upgrade Android Studio and you support and older version of Android spells trouble.
I really like Firefox. It is so much better and faster than IE. Still, in the last year that I have upgraded Firefox versions, it has been getting slower. I did quickly research Firefox 4.0 problems before upgrading and still was unprepared for a bad version. I downgraded to 3.6.17 because I could not use my browser.
