I am trying to overlay a RajawaliSurfaceView with the Earth Demo-Renderer over the Google Vision Face Tracker sample.
I use this to make the background transparent:
rajawaliSurfaceView.getHolder().setFormat(PixelFormat.TRANSPARENT);
This is the layout file of my activity:
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:surfaceview="http://schemas.android.com/apk/res-auto"
android:id="@+id/topLayout"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:keepScreenOn="true">
<com.google.android.gms.samples.vision.face.facetracker.ui.camera.CameraSourcePreview
android:id="@+id/preview"
android:layout_width="match_parent"
android:layout_height="match_parent">
<com.google.android.gms.samples.vision.face.facetracker.ui.camera.GraphicOverlay
android:id="@+id/faceOverlay"
android:layout_width="match_parent"
android:layout_height="match_parent" />
</com.google.android.gms.samples.vision.face.facetracker.ui.camera.CameraSourcePreview>
<org.rajawali3d.surface.RajawaliSurfaceView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="@+id/rajawali_surface"
android:layout_gravity="left|top" />
</FrameLayout>
It compiles without a problem, but I do not see the 3d model or the FaceGraphic from the Google Demo project. I also get this error when trying to preview the layout xml in Android Studio:

UPDATE 1:
I removed this line (rajawaliSurfaceView.getHolder().setFormat(PixelFormat.TRANSPARENT);), hoping to see the 3d scene at least, but nothing changed, I still only see the camera preview.
However, when resuming the app from anywhere I see the rotating earth for the fraction of a second, before the camera preview is started.
According to this answer, it should work as I expected it to. What do I have to do?
UPDATE 2:
(using this tutorial)
OK - Adding the line rajawaliSurfaceView.setZOrderOnTop(true); renders the 3d scene on top of my camera preview, but I still have a problem.
Neither
rajawaliSurfaceView.setEGLConfigChooser(8, 8, 8, 8, 16, 0);
rajawaliSurfaceView.getHolder().setFormat(PixelFormat.TRANSLUCENT);
nor
rajawaliSurfaceView.setEGLConfigChooser(8, 8, 8, 8, 16, 0);
rajawaliSurfaceView.getHolder().setFormat(PixelFormat.RGBA_8888);
only clear the background of the scene. I allways get a fully transparent SurfaceView. Any ideas how I can resolve this?
(Apparently the xml error only seems to be a mild anoyance I'll have to ignore.)
