Overview

This is an engineering thesis project. It's forked from TensorFlow Lite Object Detection Android Demo

• Project Article

Build the demo using Android Studio

Prerequisites

• If you don't have already, install Android Studio, following the instructions on the website.

• You need an Android device and Android development environment with minimum API 21.

• Android Studio 3.2 or later.

Building

• Open Android Studio, and from the Welcome screen, select Open an existing Android Studio project.

• From the Open File or Project window that appears, navigate to and select the tensorflow-lite/examples/object_detection/android directory from wherever you cloned the TensorFlow Lite sample GitHub repo. Click OK.

• If it asks you to do a Gradle Sync, click OK.

• You may also need to install various platforms and tools, if you get errors like "Failed to find target with hash string 'android-21'" and similar. Click the Run button (the green arrow) or select Run > Run 'android' from the top menu. You may need to rebuild the project using Build > Rebuild Project.

• If it asks you to use Instant Run, click Proceed Without Instant Run.
