Programmatically installed application gets to the list of 2D apps (Vive Focus 3)

[RodionovID]

Hello. I have a build of my Unity VR application for Vive Focus 3 that appears in the list of VR apps and works fine in case when it was installed from apk manually. But when I try to install it programmatically it gets to the list of 2D apps and doesn't work properly. AndroidManifest.xml for this app looks as follows:

<?xml version="1.0" encoding="utf-8" standalone="no"?><manifest xmlns:android="http://schemas.android.com/apk/res/android" android:compileSdkVersion="30" android:compileSdkVersionCodename="11" android:installLocation="auto" package="com.my.package.name" platformBuildVersionCode="30" platformBuildVersionName="11">

    </application>
</manifest>

Programmatically installation perfoms by another app that serves as launcher to the first app. Launcher is a common Android application that was written using .NET MAUI framework. It appears in the list of 2D apps on device. Here is installation script from this launcher:

            var context = Android.App.Application.Context;
            Java.IO.File apkFile = new Java.IO.File(apkPath);
             
            Intent intent = new Intent(Intent.ActionInstallPackage);
            var uri = Microsoft.Maui.Storage.FileProvider.GetUriForFile(context, context.ApplicationContext.PackageName + ".fileProvider", apkFile);

            intent.SetDataAndType(uri, "application/vnd.android.package-archive");
            intent.AddFlags(ActivityFlags.NewTask);
            intent.AddFlags(ActivityFlags.GrantReadUriPermission);
            intent.AddFlags(ActivityFlags.ClearTop);
            intent.PutExtra(Intent.ExtraNotUnknownSource, true);
            intent.PutExtra(Intent.ExtraReturnResult, true);

            MainActivity.Instance.StartActivityForResult(intent, requestCode);

My guess is that some data from AndroidManifest.xml is lost/not used during installation. As I know, this entry makes application to show up as a vr app on device:

<category android:name="com.htc.intent.category.VRAPP" />

It looks like installation from launcher ignores this category.

I will appreceate any help with this issue.

Hi @RodionovID,

May I know after programmatically install, your app in Library is in which category?

Check top right corner of Library.

Your app is built from Unity?

Your AndroidManifest.xml is not modified from our SDK's template?

Your app is built from Android Studio?

Hello,
@VIVE_chengnay.

After install my app in 2D category.

Yes, my app  is built from Unity.

I believe that my app's AndroidManifest.xml is not modified. Can you share a link to your  SDK's template?

My launcher app is build from Visual Studio.

 

I have another guess. My launcher app is parent activity for VR app during installation.  Because of launcher app is 2D, VR app somehow inherits category from it. Is this possible?

Hi @RodionovID,

You can find the AndroidManifest.xml template from Library\PackageCache\com.htc.upm.wave.xrsdk@<version>\Runtime\Android\AndroidManifest.xml.

You did mention if you manually install from "adb install", your app is installed as 3D?

[RodionovID]

@VIVE_chengnay, I didn't use "adb install". I  installed my app from device directly. In settings->storage->file explorer I chose apk file and installed it. In this case my app in VR category.

Hi @RodionovID,

Could you collect log for further investigation?

adb logcat > filename
Collect before your app launch until your launcher app launches another app.

@VIVE_chengnay, Here is a public link to  the log file: https://drive.google.com/file/d/1tnTbdjgZzIXsIDliO0XegBD56SqHXN0a/view?usp=drive_link

Hi @RodionovID,

I didn't find the starting point of where you start your apps.

Could you provide your apps' package name?

[RodionovID]

@VIVE_chengnay

Application package name: com.stemgames.vics.studio

Launcher package name: com.companyname.vics_science_studio_launcher
