window.requestAnimationFrame not working in newest 33.3 Meta browser in WebXR mode
I used window.requestAnimationFrame inside a WebXR app, which previously work fine in the Meta Browser, but it seems automatically update to 33.3 on June 3rd, and now this function only works when I press the Meta button to pop up the browser but not work at all when I hide the browser and enter the XR mode. Any helps? Maybe I need to change the function? But I don't see an alternative to count frames accurately. Basically I want to have a timeManager that supervise the timing of different assets in the app.
Meta Quest Browser file input fails with some file extensions
While developing a web app with three.js, I noticed an unexpected behavior of Meta Quest Browser: if I choose a .glb model file with a <input type="file"> tag, and try to access it in javascript, the browser does not allow access to the file if I manually change the extension to .png, it works. Disabling safe navigation in browser's settings does not solve the problem. The problem occur only on Meta Quest Browser: Chrome on Windows and Android behave as expected. This is the code handling file input: const fileInput = document.getElementById('file') as HTMLInputElement fileInput.addEventListener('change', (e) => loadModel((e.target as HTMLInputElement).files![0])) function loadModel(file: File) { const url = URL.createObjectURL(file) const loader = new GLTFLoader() loader.load( url, function ( gltf ) { scene.add( gltf.scene ); console.log('Model loaded') }, undefined, function ( error ) { console.error( error ); } ); } And this is the console error I get when accessing file with .glb extension GET blob:https://192.168.1.161:5500/83bfd355-2cf6-4714-bda7-3c6cf3331c58 net::ERR_ACCESS_DENIED 200 (OK) load @ three.module.js:41933 load @ GLTFLoader.js:222 loadModel @ index.ts:58 (anonymous) @ index.ts:52 Uncaught (in promise) TypeError: network error Promise.then (async) readData @ three.module.js:41973 start @ three.module.js:41969 (anonymous) @ three.module.js:41966 Promise.then (async) load @ three.module.js:41934 load @ GLTFLoader.js:222 loadModel @ index.ts:58 (anonymous) @ index.ts:52 I set up a sample web app to reproduce the problem: https://fornaeffe.github.io/vr-playground/ source code here: https://github.com/fornaeffe/vr-playground/tree/visorr-upload-bug Other details of the problem explained here: https://stackoverflow.com/questions/77068404/model-loaders-work-in-chrome-but-not-in-meta-quest-2-browser-when-using-file-in and here: https://discourse.threejs.org/t/gltfloader-works-in-chrome-but-not-in-meta-quest-2-browser/55803Support of Web Bluetooth (BLE) in Quest Browser
Hi everybody, I am trying to implement web application which should connect to wearable medical devices like ECG or PPG sensors via BLE. I am pretty familiar with Web Bluetooth on the web and implemented several applications this way. I am using A-Frame framework for VR scene and I would like to use Web Bluetooth API to get the data from the sensors. Problem is that the Web Bluetooth API responds in Meta Quest Browser like there is no BLE in the Quest device. However, I did some tests and installed the clear Chromium to the device and in this browser the BLE and all the API functions work correctly, so the Quest Browser has this problem. So finally my question is, Is this a bug or the Meta intentionally blocks these feature? PS: Why will I not use a clear Chromium instead? Well the Quest browser is optimized for the Quest device and unfortunately in the Chromium the VR scene does not work very well (mainly because missing Google services). Thanks for all possible help. 🙂 David
Meta Quest Browser Bug - 3D Scene Jitter - Developer - THREE.js
We are reporting a bug and seeking help. It is most likely a bug of Meta Quest Browser or related infrastructures. we are developers making 3D VR browser based Apps. We open our 3D Scenes (rendered by THREE.js) in Meta Quest Brower. The issue is, we notice that the scene would jitter even for the simplest example link from THREE.js official website. To reproduce, just open the following link in Meta Quest Browser and use controllers to drag the scene to rotate. https://threejs.org/examples/#webgl_animation_keyframes Jitter will likely to show up (not every time but pretty frequent). We believe this is more likely to be a bug of quest/browser other than the web page because the web page is simple and good in every other desktop/mobile browsers. One hint is, the jitter seem only happen (or much more frequent) when Passthrough mode is turned off. If you can not reproduce please refer to this video - it's captured by phone directly into the quest lens.: https://www.youtube.com/watch?v=hEha6OoYvyA This issue currently impacts our app badly - if anyone knows anything please let us know. Appreciate so much!!
Animation gets paused in Meta Quest Browser
We have created a vr app. We have used GSAP library to create animation. Based on conditions, the animation gets started. Running the VR app in meta quest browser, the animation gets paused. When I maximize the browser again then only animation starts working. How to I ensure my animation doesn't get paused in Metaquest browser and play smoothly?
Meta quest browser STT and TTS support.
The meta quest browser is currently on a lower version of chromium and the features like TTS and STT are not working on it. Does anyone know when the next update to the browser would come or at least how I can get the STT and TTS working on the quest browser before that update? Any help would be greatly helpful.
Open application from Quest web browser through a "android:scheme" Deeplink
I followed the Android deep linking documentation to be able to open my Quest application from the Quest web browser: 1. Edit the AndroidManifest.xml of the application to add this: <intent-filter> <action android:name="android.intent.action.VIEW" /> <category android:name="android.intent.category.DEFAULT" /> <category android:name="android.intent.category.BROWSABLE" /> <!-- Accepts URIs that begin with "example://gizmos” --> <data android:scheme="example" android:host="gizmos" /> </intent-filter> 2. Deploy the application to the Quest device 3. Run this command where "com.example.android" is the application pacakge: adb shell am start -W -a android.intent.action.VIEW -d "example://gizmos" com.example.android This works, e.g the previous command launches the application on the device. The "android.intent.category.BROWSABLE" is here to allow this intent action to be launched from a web browser. So now please open the Quest web browser on the device, then try to navigate to the "example://gizmos" URL. This does not work, e.g the application is not launched by querying the "example://gizmos" URL from the Quest web browser. The Android Log cat shows the following output: 2023/05/15 10:52:57.625 24304 24304 Info chromium [INFO:web_contents_impl.cc(6947)] WebContentsImpl Loading end: ID = 3 2023/05/15 10:52:57.630 24304
