Looking at your build.gradle you have both the compileSdkVersion of Symbol Technologies AND are providing the emdk.jar as a provided dependency. You would only need to do one of these two things
I ran up GitHub - Zebra/samples-emdkforandroid-6_4 at ProfileDataCaptureSample1 on my Windows machine which I believe matches what the tutorial is producing, my gradle file is attached.
You will also need all the SDK dependencies (e.g. buildTools 25) but Android Studio should download those automatically.
Hope that helps
