I am getting several OpenGL errors in the Android Emulator when running simple code to draw in a SurfaceView. As a result, the SurfaceView does not draw when running in the emulator. The same code runs correctly on a device (in this case, an Amazon Fire HD 8 (2017 - KFDOWI)).
Here are the errors:
Emulator: android/android-emugl/host/libs/Translator/GLES_V2/GLESv2Imp.cpp:glReadPixels:2827 error 0x502
Emulator: sPrepareTexImage2D:3087 failed validation
Emulator: android/android-emugl/host/libs/Translator/GLES_V2/GLESv2Imp.cpp:glTexImage2D:3133 error 0x500
Emulator: sPrepareTexImage2D:3087 failed validation

Emulator: android/android-emugl/host/libs/Translator/GLES_V2/GLESv2Imp.cpp:glTexSubImage2D:3237 error 0x500
Here is the code:
import android.content.Context;
import android.graphics.Canvas;
import android.graphics.Color;
import android.util.AttributeSet;
import android.view.SurfaceHolder;
import android.view.SurfaceView;
public class CustomSurfaceView extends SurfaceView implements SurfaceHolder.Callback {
private SurfaceHolder surfaceHolder;
public CustomSurfaceView(Context context) {
super(context);
init();
}
public CustomSurfaceView(Context context, AttributeSet attributeSet) {
super(context, attributeSet);
init();
}
private void init() {
this.surfaceHolder = getHolder();
surfaceHolder.addCallback(this);
}
@Override
public void surfaceCreated(SurfaceHolder surfaceHolder) {
Canvas canvas = surfaceHolder.lockCanvas();
canvas.drawColor(Color.RED);
surfaceHolder.unlockCanvasAndPost(canvas);
}
@Override
public void surfaceChanged(SurfaceHolder surfaceHolder, int i, int i1, int i2) {
}
@Override
public void surfaceDestroyed(SurfaceHolder surfaceHolder) {
}
}

Also, I can run OpenGL ES 2.0 code in this same emulator without these issues.
Disable hardware acceleration.
[open virtual device configuration -> edit virtual device -> use software mode graphics]
