WIP queueEvent

[hannesa2]

It's just a demonstration what I did.

I use queuEvent please see and log the current Thread out.

Indeed it's the wrong thread

[hannesa2]

I guess this is the causing line }, ContextCompat.getMainExecutor(this))

[hannesa2]

In an other project I do this

  LiveData<ProcessCameraProvider> getProcessCameraProvider() {
    if (cameraProviderLiveData == null) {
      cameraProviderLiveData = new MutableLiveData<>();

      ListenableFuture<ProcessCameraProvider> cameraProviderFuture =
          ProcessCameraProvider.getInstance(getApplication());
      cameraProviderFuture.addListener(
          () -> {
            try {
              cameraProviderLiveData.setValue(cameraProviderFuture.get());
            } catch (ExecutionException | InterruptedException e) {
              Log.e(TAG, "Unhandled exception", e);
            }
          },
          ContextCompat.getMainExecutor(getApplication()));
    }

I grabbed it from here

Sumarize: avoid val frame: Frame = session.update() in private fun bindCameraUseCases()

Hi @hannesa2,

I am not sure I understood your changes fully. By any chance, you got time to test it on your end. Is it working for you?

[hannesa2]

No, I didn't finished it till now.
I (currently) only pointed out what's exactly wrong and showed you a working way to handle .addListener()

[hannesa2]

Now I run into

[type.googleapis.com/util.ErrorSpacePayload='ArStatusErrorSpace::AR_ERROR_TEXTURE_NOT_SET']

But the previous error MISSING_GL_CONTEXT is gone !

Can you solve it ?

[abhishekk06]

As per this, it happens when we call Session.update without having done session.setCameraTextureNames.

Any idea how to pass texture ID here?

[hannesa2]

eg https://github.com/csi111/ARSample/blob/c17c986c0c457c8f6c3041d5efea4c94d0c694a6/app/src/main/java/com/csi/arsample/MainActivity.kt#L263-L266

give it a try

[abhishekk06]

I don't understand how to pass "textureId" here. I tried hardcoding it to 0 but I am again getting a black screen and the following prints in the console.

E/native: session.cc:2264 Invalid ray produced by view data!
W/sessionDraw: GLThread 18038
E/native: session.cc:2264 Invalid ray produced by view data!

Hi @hannesa2,

By any chance did you able to figure what can go wrong?
Can you please suggest how to debug further?

[hannesa2]

First, try it by your own. I see no commit from you

[abhishekk06]

@hannesa2 sorry, I missed pushing commit with my second last comment. Please take a look.

Now I see "Invalid ray produced by view data!" after setting the texture name. Checking further to see if I did something wrong.

[abhishekk06]

I think I need to use surfaceview here but I am not sure how to get texture ID for that. I don't see any similar helper function available.

[abhishekk06]

As per the link given below, I set geometry when trying to place anchor but now I don't see any activity at all

temporary hack for "Invalid ray produced by view data"

[hannesa2]

I formatted code again, to only see significant changes from you.
You use an own (non standard) codestyle

[abhishekk06]

Yeah. Sorry i haven't configured android studio correctly yet. It's having default setting.

I am blocked here for a long time. Not sure how to proceed further :( @hannesa2 @owahltinez your suggestion is much needed.
