???protected void onStart() {
???????Log.i(TAG, "onStart");

Why i get this (?) symbol in the code?

Because I have a AMD processor and not a intel. I can't use HAXM and therefore also not the Android Virtual Device. I'm using genymotion instead. Which works great regarding the emulation. But when I try to use the android device monitor it does not show the oncreate, onstart, etc.. It does show all other activities, but not those logs. Anybody have an idea why? And better yet a solution to do make it work?

Hello Bucky, Thanks for this tutorial and all. Before watching this, Android studio always appear overwhelming. You must have put a lot of effort making this video. But for crying out loud- Why! Why!! Why do you belch to the mic, it's pretty disrespectful.
