setForeground not working for wear devices using GLSurfaceView

[tobrun]

We use View.setForeground(R.color.someColor) to hide the black surface of GLSurfaceView until we have rendered the background of a style to provide a better user experience. Android wear watches however, running 8.0.0, don't draw the foreground color:

Workaround is to use a TexureView instead.

Looking more into this and I'm also able to reproduce this for TextureView but only with initial launch. Since this a wear only issue, I'm suggesting to use an overlain transparent View. With this the foreground color (issue from OP) seems to be working again.

<FrameLayout
        xmlns:android="http://schemas.android.com/apk/res/android"
        xmlns:tools="http://schemas.android.com/tools"
        android:layout_width="match_parent"
        android:layout_height="match_parent">

    <com.mapbox.mapboxsdk.maps.MapView
            android:id="@+id/mapView"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            tools:deviceIds="wear"
            tools:mapbox_renderTextureMode="true" />

    <View
            android:background="@android:color/transparent"
            android:layout_width="match_parent"
            android:layout_height="match_parent"/>

</FrameLayout>
