Crash on OnePlus X (libtango_hal.so is missing) #7

rafaelvcaetano · 2017-08-30T19:50:12Z

Sample app fails to initialize with the following stack trace:

E AndroidRuntime: FATAL EXCEPTION: main

This is the same error that appears when I attempt to run a project with the official"unitygar.aar"

tomthecarrot · 2017-08-30T19:55:22Z

From the log it looks like the sample app cannot load the Tango shared library. Did you install the ARCore Service? See the "Preparing your Device" section of Google's instructions https://developers.google.com/ar/develop/java/getting-started

rafaelvcaetano · 2017-08-30T20:18:31Z

Yes. Also, I forgot to mention I'm running Lineage OS with Android 7.1.2

rafaelvcaetano · 2017-08-30T20:31:48Z

Found more information in the logcat that might prove useful:

I ActivityManager: Displayed com.tomthecarrot.helloar/com.unity3d.player.UnityPlayerActivity: +288ms
I TangoClientLibLoader: Pure Java path, not loading libtango_client_api.so at all.
D ApplicationLoaders: ignored Vulkan layer search path /data/app/com.google.tango-1/lib/arm:/system/fake-libs:/data/app/com.google.tango-1/base.apk!/lib/armeabi-v7a for namespace 0x82f21090```

tomthecarrot · 2017-08-30T20:51:42Z

Thanks for that info. not loading libtango_client_api.so at all is an interesting error. I don't remember seeing that in any other logs.

Also interesting that it's ignoring the Vulkan layer search path; I believe that the referenced path is the correct one for ARCore.

Did that log appear before the first log you posted?

rafaelvcaetano · 2017-08-30T21:13:39Z

It happened before. Here is a full logcat since launch untill crash: https://pastebin.com/3eD1pu9d

tomthecarrot · 2017-08-30T21:43:52Z

Thanks for posting that. The following line indicates that the native library cannot find a suitable camera.

ndk_camera: Zero cameras detected. Camera system initialization complete

Can you ensure the camera permission (in Android App Settings) is enabled for both TangoCore and the sample app?

rafaelvcaetano · 2017-08-30T22:12:05Z

Permissions were disabled for both apps (nice catch!) but the same error is still happening.

tomthecarrot · 2017-08-31T01:36:38Z

Could be Vulkan-specific. See #5

tomthecarrot · 2017-08-31T16:23:29Z

Added the known devices to a research document to try to isolate the issue. OnePlus X is the only device on the list with an Adreno 330, so it's possible that the architecture is currently unsupported. Let's try to fix that :)

rafaelvcaetano · 2017-08-31T22:20:11Z

I went a bit deeper into the problem and decompiled the arcore-preview.apk. Inside I found some methods that check if the current device is one of the supported. You can find this method:

private static boolean deviceCalibrationAvailable()
{
    return (Build.FINGERPRINT.contains("sailfish:7")) || (Build.FINGERPRINT.contains("sailfish:O")) || (Build.FINGERPRINT.contains("sailfish:8")) || (Build.FINGERPRINT.contains("marlin:7")) || (Build.FINGERPRINT.contains("marlin:O")) || (Build.FINGERPRINT.contains("marlin:8")) || (Build.FINGERPRINT.contains("walleye:O")) || (Build.FINGERPRINT.contains("walleye:8")) || (Build.FINGERPRINT.contains("taimen:O")) || (Build.FINGERPRINT.contains("taimen:8")) || (Build.FINGERPRINT.contains("SC-02J/SC-02J:7")) || (Build.FINGERPRINT.contains("SCV36_jp_kdi/SCV36:7")) || (Build.FINGERPRINT.contains("dreamqlteue/dreamqlteue:7")) || (Build.FINGERPRINT.contains("dreamqltesq/dreamqltesq:7")) || (Build.FINGERPRINT.contains("dreamqlteldusq/dreamqltesq:7")) || (Build.FINGERPRINT.contains("dreamqltezm/dreamqltecmcc:7")) || (Build.FINGERPRINT.contains("dreamqltevl/dreamqltecan:7")) || (isSupportedExynosDevice());
}

These translate to the following:

Salfish - Pixel
Marlin - Pixel XL
Taimen - Pixel 2 (apparently)
Walleye - Pixel 2 XL (apparently)
All others - Galaxy S8 variants

These methods are inside the class com.google.atap.tangoservice.SupportedDevices and is accessed by com.google.tango.jni.TangoCameraNative on its initialize() method. So, I would say that this is a pretty decent place to start looking. Unfortunately I'm not experienced with recompiling jars and APKs. @tomthecarrot do you think you can take a look at it?

tomthecarrot · 2017-08-31T22:27:14Z

Thanks for your research! I'll look into it now. Your information is useful for this idea.

tomthecarrot · 2017-09-01T01:15:12Z

I built an early version of a modified ARCore Service, which seems to be functional without per-app modifications, all on my "unsupported" device.

Please try it on your device and let me know if it works. You'll need to uninstall the existing "Tango Core" first. Thanks!

rafaelvcaetano · 2017-09-01T11:23:46Z

Thanks for your effort! Unfortunately the same error is still occurring.

cleitner · 2017-09-09T12:32:27Z

I have the same couldn't find "libtango_hal.so" error on the bq Aquaris X5 Plus. I suspect the error in this case is an unsupported CPU, because the arcore-preview(-modified).apk only contains arm64 precompiled libraries and my phone has an armv7l CPU.
