AR apps in Android Studio

Android Studio projects with using Augmented Reality libraries. Here will be simple apps with adding different objects to the scene, animations of 3d objects, games with shooting to the objects, face detection and masks, playing video on scenes and many other simple projects.

Requirements for AR apps

Add to the android section in buidl.gradle following code after buildTypes.

    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }

Add to the dependencies section in buidl.gradle following code after all implementations.

    // Provides ARCore Session and related resources.
    implementation 'com.google.ar:core:1.11.0'

    // Provides ArFragment, and other UX resources.
    implementation 'com.google.ar.sceneform.ux:sceneform-ux:1.11.0'

    // Alternatively, use ArSceneView without the UX dependency.
    implementation 'com.google.ar.sceneform:core:1.11.0'

Add to the manifest section in AndroidManifest.xml permissions before application section and add meta-data inside of application

    <uses-permission android:name="android.permission.CAMERA" />
    <uses-feature android:name="android.hardware.camera.ar" android:required="true"/>
    ...
    <application
        ...
        <meta-data android:name="com.google.ar.core" android:value="required" />
    </application>

AugmentedR_1

Placing simple 3d object loaded from Googles' poly website to the plane.

• Follow Requirements section
• Load .obj file from Googles' poly
• Create Sample Data Directory, copy and past your .obj and .mtl files there
• Click Import Sceneform Asset on your .obj file and your object will appear in assets folder
• Create fragment element in your activity layout
• Some magic (I mean code - detect the plane and add your model, don't forget to do it transformable for resizing and moving) in your activity class and it's ready!

AugmentedR_2

Placing simple 3d objects like cube, sphere and cylinder to the plane.

• Follow Requirements section
• Create fragment element in your activity layout with buttons for each object
• Add on tap plane listener and create there selected object
• Don't forget to make it transformable for moving and resizing

AugmentedR_3

ViewPager with images on the plane

• Follow Requirements section
• Create fragment element in your activity layout and create layout with ViewPager
• Add on tap plane listener then create ViewPager with adapter and add them to the scene
• Make it NOT transformable for easy switching between images

AugmentedR_4

Adding fox mask to the face

• Follow Requirements section
• Load some mask for face with .fbx and import it
• Create fragment element in your activity layout
• Create Custom Fragment which extends ArFragmet
• Render it and add to the scene

No gifs for this app!

AugmentedR_5

Game - Kill the flying president

• Follow Requirements section
• Load some 3d object file from Googles' poly
• Create fragment element in your activity layout, add buttons and UI elements
• Add elements to the scene in different points
• Add bullets and write shooting mechanism
• Detect collisions and remove the objects
• Add sound for bullets

Area 51 AR

As a final project I developed Augmented Reality shooter and published it in Play Market. Feel free to play it and leave your comments. Here is the instructions how to build your own shooter.

• Follow Requirements section
• Load some 3d objects from Googles' poly or other sites
• Create fragment element in your activity layout, add buttons and UI elements
• Add elements to the scene in different points in front of you and add thread for updating thier positions
• Add bullets and write shooting mechanism
• Detect collisions and remove the objects
• Add few more levels and bosses with abilities
• Add analytics, ads, music and promo codes
• Publish it!

SolveIt

Simple project for solving math expressions using text detection.

• Implement com.google.android.gms:play-services-vision latest version
• Detect text using camera
• Add math expressions solver from string
• Add view for entering text, if user has troubles with detecting expression
