Hi,
If you are wholly unfamiliar to Android Studio and Java development, I suggest you to use the pre-built binaries path/to/sw/android/tlogger/Releases, or to you use the Google Play Store. If possible, of course.
The Android code in the SDK is provided to help you started, but is by no means production ready code. We are also unable to provide much support about this, as APP development lies outside our area of expertise - we're more into chips ;-)
That said; the code and project files are created using the older Android Studio version 3.0.1. The error you posted above refers to this: the project properties indicate the use of a specific gradle plugin for Android Student v3.0.1. You don't have this on your local machine, and the automatic retrieval fails.
The current stable version of Android Studio is 3.4.1. Normally, when opening the project, Android asks you to upgrade the gradle plugins.

If it somehow fails to do this for you, you can manually edit path/to/sw/android/tlogger/build.gradle and change the classpath to
classpath 'com.android.tools.build:gradle:3.4.1'
After picking up a more recent gradle version, building should continue and finish without issues.
Kind regards,
Dries.
