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:
