Setup Guide Android

Project Setup Android Studio

You can start either off with a blank project. The necessary steps are provided below. Alternatively you can use the SampleProject that is already bundled with the SDK, where the necessary configuration steps have already been made.

  • Create a new Android Application Project

  • Copy the file libs/wikitudesdk.aar into the libs folder of your module. (<project-root>/<module-name>/libs)

  • Open build.gradle from your module, add the wikitudesdk.aar as a dependency and tell gradle to search the libs folder, like in the code below.

android {

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile (name: 'wikitudesdk', ext:'aar')
    compile ''

repositories {
        dirs 'libs'
  • If you already purchased a license, please set the applicationId to the package name you provided us with.
    defaultConfig {
        applicationId "xxxx"
  • Add the following permissions to your AndroidManifest.xml
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
<uses-permission android:name="android.permission.ACCESS_GPS" />
<uses-permission android:name="android.permission.CAMERA" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-feature android:name="" android:required="true" />
<uses-feature android:name="android.hardware.location" android:required="true" />
<uses-feature android:name="android.hardware.sensor.accelerometer" android:required="true" />
<uses-feature android:name="android.hardware.sensor.compass" android:required="true" />
<uses-feature android:glEsVersion="0x00020000" android:required="true" />
<uses-sdk android:targetSdkVersion="19" android:minSdkVersion="9"/>
  • The activity holding the AR-View (called architectView in the following) must have set android:configChanges="screenSize|orientation" in the AndroidManifest.xml, for example this could look like:
<activity android:name="com.yourcompany.yourapp.YourArActivity"

AR View in Activity

Keep in mind that the Wikitude SDK is not a native Android SDK as you know from other SDK's. The basic concept is to add an architectView to your project and notify it about lifecycle events. The architectView creates a camera surface and handles sensor events. The experience itself, sometime referred to as ARchitect World, is implemented in JavaScript and packaged in your application's asset-folder (as in this project) or on your own server. The experiences are written in HTML and JavaScript and call methods in Wikitude's AR-namespace (e.g. AR.GeoObject).

You have to include

 <script src=""></script>

in your HTML files to use the AR namespace and the architectView will handle them properly. To test an ARchitect World on a desktop browser, you must include ade.js tool instead to avoid JavaScript errors and see a development console.

It is recommended to handle your augmented reality experience in a separate Activity. Declare the architectView inside a layout XML. E.g. Add this within FrameLayout's parent tags.

<com.wikitude.architect.ArchitectView android:id="@+id/architectView"
   android:layout_width="fill_parent" android:layout_height="fill_parent"/>

ArchitectView is creating a camera surface so ensure to properly release the camera in case you're using it somewhere else in your application. Besides a camera (front or back-facing) the ArchitectView also makes use of compass and accelerometer values, for a full list of requirements refer to the list of supported devices.

ArchitectView.isDeviceSupported(Context context) checks whether the current device has all required hard- and software in place or not.

Note: Make AR-View only accessible to supported devices

It is very important to notify the ArchitectView about life-cycle events of the Activity. Call architectView's onCreate(), onPostCreate(), onPause(), onResume(), onDestroy() inside your Activity's lifecycle methods. Best practice is to define a member variable for the architectView in your Activity. Set it right after setContentView in Activity's onCreate(), and then access architectView via member-variable later on.

this.architectView = (ArchitectView)this.findViewById( );
final ArchitectStartupConfiguration config = new ArchitectStartupConfiguration();
config.setLicenseKey( * license key */ );
this.architectView.onCreate( config );
Note: Since Android 6.0+ you need to make sure your app has the camera runtime permission before calling architectView.onCreate( config ).

Activity's onPostCreate() is the best place to load the AR experience.

this.architectView.load( "YOUR-AR-URL" );

The architectView.load() argument is the path to the html file that defines your AR experience. It can be relative to the asset folder root or a web-url (starting with http:// or https://). e.g. architectView.load('arexperience.html') opens the html in your project's assets-folder, whereat architectView.load('') loads the file from a server.

Note: You can only pass arguments to the HTML file when loading it via URL. The following will not work: architectView.load('arexperience.html?myarg=1')
