This guide explains how to start using LÖVR on Android devices like the Oculus Go and Oculus Quest.
After setting the device up for development, the LÖVR Android .apk is "sideloaded" onto the device. From there, a LÖVR project on a PC can be sync'd to the device, and will automatically reload whenever the files are changed.
First, make sure your device is set up for development. Oculus has official device setup guides for both the Oculus Quest and Oculus Go, but there are lots of other guides on the internet for how to do this. The key things are:
- Enabling development mode on the device.
- Installing the
adbtool used to communicate with the device.
Install the APK
Download the latest release version of the test apk from the
Install it to the device:
$ adb install /path/to/test-release.apk
Try running it by navigating to the "Library" -> "Unknown Sources" menu of the headset and running
org.lovr.test app. You should see a message about how to upload files.
Running a Project
Now we can create a LÖVR project, which is a folder with some code and assets in it. Create a
hello-world and add this code to a file named
main.lua in there:
function lovr.draw() lovr.graphics.print('hello world', 0, 1.7, -3, .5) end
adb to sync it to the device:
$ adb push --sync /path/to/hello-world/. /sdcard/Android/data/org.lovr.test/files/.lodr
You should see the "hello world" message!
If the app is already running when a project is pushed, it will reload with the new code. Also note
. in the path to the project, it's important!
- If you need to use
adb logcat -s LOVR.
The next guide will teach you how to make fancier projects using Callbacks and Modules.
