Oculus VR Hello World for Android Developers

Install and Run the Oculus hello_xr Sample App

Get your Oculus ready

  • Enable Developer Mode on your Oculus.
  • Connect your Oculus to your laptop (depending on your laptop you might need a USB 2.0 to USB C cable). Put the headset on and select “Allow” to trust the connected device.

Installing the Oculus sample app APK

  • You can download the APK I built from here and install it directly:
  • Install the APK using adb install, or SideQuest. Skip ahead below to the Run section if you don’t want to build the sample app.

Building from Android Studio

  • Clone my repo (I have applied all the manual steps that the hello_xr sample project required, so you don’t have to):
  • In Android Studio, choose File -> Open… and select the OculusHelloXR folder for the repo you just cloned.
  • Let the Gradle build finish and then click the play button to run the app.
Android Studio “Run app” option
  • You might see an “Error while Launching activity”. Don’t worry — this is benign, everything will still work! You just need to put on your headset and launch the app from the Oculus Apps menu (see next section).

Launching an APK from an unknown source

  • Select the “Unknown Sources” at the top right in your Apps menu, and select the “Hello XR” app to launch it.

  • Now you’ll be able to look at some cubes in the sample app. Your controllers will each directly manipulate one of them. Enjoy!
