Native Android

Embedding TutAR 3D viewer in a native Android app

Prerequisites

• This guide expects basic Android development knowledge with kotlin

• Get a Connect3D Vendor Account from TutAR by sending a mail at <[e-mail]>.

• Generate an API key from the Connect3D dashboard

Getting User Permissions

The AR functionality in the viewer requires Camera access, Make sure to take camera permission from the user.

AndroidManifest.xml

<manifest>
<!--
rest of the code
-->
    <uses-feature android:name="android.hardware.camera" android:required="false" />
    <uses-permission android:name="android.permission.CAMERA" />
    <uses-permission android:name="android.webkit.PermissionRequest" />
    <uses-permission android:name="android.permission.INTERNET" />

<manifest>

override fun onCreate(savedInstanceState: Bundle?) {
// rest of the code
    if (ContextCompat.checkSelfPermission(this, Manifest.permission.CAMERA) != PackageManager.PERMISSION_GRANTED) {
        ActivityCompat.requestPermissions(this, arrayOf(Manifest.permission.CAMERA), MY_PERMISSIONS_CAMERA)
    } 
}

Embedding the Viewer

Refer the below example implementation using the native webkit.WebView

res/layout/main_activity.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="match_parent"
    android:layout_height="match_parent">
    <WebView  xmlns:android="http://schemas.android.com/apk/res/android"
        android:id="@+id/webview"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        />
</LinearLayout>

        }   
        webView.webChromeClient = object : WebChromeClient() {
            override fun onPermissionRequest(request: PermissionRequest) {
                request.grant(request.resources)
