This error comes on both it real device and genymotion emulator I think there is something related to the fact that there is no visual representation in the layout editor.

this is the layout:

<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"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
android:paddingBottom="@dimen/activity_vertical_margin"
tools:context=".MyActivity">

<GLSurfaceView
    android:layout_width="match_parent"
    android:layout_height="match_parent" />

Answer 1

GLSurfaceView is in the android.opengl package, not android.view.

Hence, in your XML layout file, change GLSurfaceView to android.opengl.GLSurfaceView.
