+# MediaPipe Tasks Holistic Landmark Detection Android Demo
+
+### Overview
+
+This is a camera app that continuously detects the body, hand, and face
+landmarks in the frames seen by your device's back camera, using a
+custom **task** file.
+
+The task file is downloaded by a Gradle script when you build and run the app.
+You don't need to do any additional steps to download task files into the
+project explicitly unless you wish to use your own landmark detection task. If
+you do use your own task file, place it into the app's assets/tasks directory.
+
+This application should be run on physical Android devices with a back camera.
+
+![Holistic Landmarker Demo](screenshot.jpg?raw=true "Holistic Landmarker Demo")
+
+## Build the demo using Android Studio
+
+### Prerequisites
+
+* The **[Android Studio](https://developer.android.com/studio/index.html)** IDE.
+  This sample has been tested on Android Studio Giraffe.
+
+* A physical Android device with a minimum OS version of SDK 24 (Android 7.0 -
+  Nougat) with developer mode enabled. The process of enabling developer mode
+  may vary by device.
+
+### Building
+
+* Open Android Studio. 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 mediapipe/examples/holistic_landmarker/android directory. Click OK. You
+  may
+  be asked if you trust the project. Select Trust.
+
+* If it asks you to do a Gradle Sync, click OK.
+
+* With your Android device connected to your computer and developer mode
+  enabled, click on the green Run arrow in Android Studio.
+
+### Models used
+
+Downloading, extraction, and placing the models into the *assets/tasks* folder
+is
+managed automatically by the **app/build.gradle.kts** file.
