Unity app crushes when trying to launch it from another app (Oculus Quest 2)
Hello. I have a build of my VR Unity app for Oculus Quest 2 and it starts and works just fine. In addition for this app I have a launcher - an android 2D app that was written using .NET MAUI framework. This launcher allows to start Unity app by clicking "Launch" button. Here is button handler code: static partial void PLaunch() { PackageManager packageManager = Android.App.Application.Context.PackageManager; Intent intent = packageManager.GetLaunchIntentForPackage(MainPage.appPackageName); MainActivity.Instance.StartActivity(intent); } With VR headsets from another companies this handler works as expected. It launches my Unity app as if it was launched directly. But in case of Oculus Quest 2 it tries to launch my Unity app inside of launcher window as 2D app and then it crushes. I want to figure out how to fix it. Here is device logs for two scenarios: direct_app_launch.txt - Unity app launches directly (works ok): https://drive.google.com/file/d/1kIGc_p14XDXfwghB8ernp3QY7szBWg6L/view?usp=drive_link launcher_app_launch.txt - Unity app launches using launcher (crash happening): https://drive.google.com/file/d/1b3EaeV5-rWFZLmOotM36YpGacG4EEmtT/view?usp=drive_link Package names Unity app: com.stemgames.vics.studio launcher: com.stemgames.vics_science_studio_launcher I will appreceate any help with this issue.
Issues with the APK during validation
I'm having problems with my app's Manifest, I want to publish it on the ALPHA channel, but when building I get errors, even using "Create store-compatible AndroidManifest.xml" I tried to debug, I added: |android:exported="true"| and |android:installLocation="auto"| in the Manifest, I was able to build it, but I couldn't upload it. OVR Platform Tool log: NOTE: Your manifest includes the following permissions restricted by Oculus: - android.permission.RECORD_AUDIO - android.permission.MODIFY_AUDIO_SETTINGS Please remove these permissions if they are not needed by your application. If they are needed, you must include justification in the “Notes for the Reviewer” field when submitting your application for review. Failure to provide justification will result in the rejection of your application. This app contains both 32-bit (armeabi-v7a) and 64-bit (arm64-v8a) libraries. This consumes extra storage and increases download times. Consider updating your build to target 64-bit only. Preparing for upload... Uploading APK... Uploading...

Please check that the APK meets the `Application Manifest Requirements` and then resubmit your app. * APK install location must be "automatic" (android:installLocation in AndroidManifest.xml). Read the documentation at: https://developer.oculus.com/distribute/publish-mobile-manifest/ Even with |android:installLocation="auto"| I still get this error. What can I do? I need the microphone because I'm using Photon Voice My Manifest: <?xml version="1.0" encoding="utf-8" standalone="no"?> <manifest xmlns:android="http://schemas.android.com/apk/res/android" android:installLocation="auto"> <application android:label="@string/app_name" android:icon="@mipmap/app_icon" android:allowBackup="false"> <activity android:theme="@android:style/Theme.Black.NoTitleBar.Fullscreen" android:configChanges="locale|fontScale|keyboard|keyboardHidden|mcc|mnc|navigation|orientation|screenLayout|screenSize|smallestScreenSize|touchscreen|uiMode" android:launchMode="singleTask" android:name="com.unity3d.player.UnityPlayerActivity" android:excludeFromRecents="true" android:exported="true"> <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> </activity> <meta-data android:name="unityplayer.SkipPermissionsDialog" android:value="false" /> <meta-data android:name="com.samsung.android.vr.application.mode" android:value="vr_only" /> </application> <uses-feature android:name="android.hardware.vr.headtracking" android:version="1" android:required="true" /> <uses-feature android:name="com.oculus.feature.PASSTHROUGH" android:required="true" /> </manifest> UPDATE: It looks like it's a bug from Unity, I was able to upload my APK using the workaround in the comments of this post: https://issuetracker.unity3d.com/issues/android-install-location-changes-when-exporting-project
