Android Studio ADB Doesn't Recognize Samsung Galaxy S5

Problem:  You're trying to test your awesome Android/Java code on a real live phone connected via USB, but Android Studio doesn't recognize your device no matter what you do.  Well, here is a checklist of items to make sure you have to ensure your device is recognized:

In Short:

• Turn on Debugging Options and enable USB Debugging
• Install Google USB Drivers from SDK Menu in Android Studio
• Install "Samsung USB Driver for Mobile Phones"
• Restart adb and check if your phone is in the list
• Accept the RSA Fingerprint verification on phone

Details:

• Connect your device via USB to your computer
• Turn on Debugging options on your phone by tapping "Build Number" seven times in the "About Device" in your phone settings
• Open the "Developer Options" in your phone settings and make sure "USB Debugging" is checked
• Go to the "SDK Manager" of Android Studio and install "Google USB Driver"
• Install "Samsung USB Driver for Mobile Phones" from Samsung:  http://developer.samsung.com/technical-doc/view.do?v=T000000117
• Restart ADB and verify device from command line (I only typed adb devices):  
• C:\Users\hans\AppData\Local\Android\sdk\platform-tools\adb kill-server
• C:\Users\hans\AppData\Local\Android\sdk\platform-tools\adb start-server
• C:\Users\hans\AppData\Local\Android\sdk\platform-tools\adb devices
• Somewhere in this last step, your phone will prompt you for an "RSA Fingerprint" verification.  In this case, you accept.  If you see this, then you're GOLDEN!
