Cannot run in an emulator

[janpietersh]

Describe the bug
Unable to open application on Android after following the install instructions for windows. I have been trying for a week now - have started over twice already.

To Reproduce
Steps to reproduce the behavior:

1. Follow the install instructions
2. Start the app in emulator and it crashes. Android warns about application repeatedly crashing.

Other

• Android
• node --version --> v16.13.2
• npm --version --> 8.1.2
• cmake version 3.19.6 (latest version was causing errors as per other issues)

This might be better asked on the forum. I have never seen this error before. Do you have a physical device to try in case it is emulator specific?

Also, just in case it matters, what version of Android Studio are you using and what version of the NDK are you targeting?

[janpietersh]

thanks @bghgary for helping.

Android Studio Bumblebee - 2021.1.1 Patch 2
I only have NDK 21.3.6528147 installed (same as specified in apps/playground/0.64/android/build.gradle)

How are those .so files linked? I don't see why my program cannot see them.

[janpietersh]

Could somebody share versions of above programs that do work?

[ryantrem]

Here are my Android Studio and NDK versions, and I didn't run into any issues last time I rebuilt:

If I recall, the output .so is supposed to be included in the packaging by virtue of the project being pulled in as part of the RN auto linking. I don't think there is any Babylon React Native specific configuration for that if I recall.

[ryantrem]

I wonder if something changed in the tooling and native libs are no longer automatically packaged in the app bundle or something? I saw some questions on Stack Overflow that sounded maybe similar, with some references to a gradle property called useLegacyPackaging, but not sure if this is really related or not.

[janpietersh]

I installed Android Studio 4.1.3 and re-installed Babylon React Native from latest source. This is what I am getting right now on npm run android.

Is this not meant to work on windows - it looks like the path separators are for linux/mac. Also adb is in my path.

When I run adb logcat I am seeing this:

It is opening the app very briefly. I can see the button for XR and then it crashes. Maybe this is progress since the errors are different?!

Is this not meant to work on windows

Most of us run Android Studio on Windows. I don't know why you are seeing all of these issues. I'm using Android Studio Arctic Fox | 2020.3.1 Patch 3 right now if that helps.

[janpietersh]

thanks it seems to work on a real device and not emulator. i managed to borrow a device, but I do not have an android device. does this mean that I cannot develop with an emulator - is anybody able to work with an emulator?

[ryantrem]

@janpietersh can you try these steps for troubleshooting Android emulator issues? https://github.com/BabylonJS/BabylonNative/blob/master/Documentation/AndroidEmulator.md

Specifically, check the OpenGL ES3 section first.

We have a Babylon React Native related issue for getting this documented in a way that people can easily find it from the BRN docs, but we haven't addressed it yet.

[janpietersh]

thanks @ryantrem - did not find that emulator link before! 😄 in addition I believe the path separators was because i was using a cmd instead of powershell.
