Android SurfaceView Emulator OpenGL Errors

Question

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:glTexImage2D:3133 error 0x500

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) {
    }
}

Activity:

System Information:

• MacOS High Sierra 10.13.2
• 16 GB RAM
• Android Studio 3.0.1
• JRE 1.8.0_152
• HAXM 6.2.1

AVD Information:

• API 25
• Graphics: Automatic
• RAM: 1536 MB

App Information:

• API 26
• Min SDK: 19

Also, I can run OpenGL ES 2.0 code in this same emulator without these issues.

Answer 1

Disable hardware acceleration.

[open virtual device configuration -> edit virtual device -> use software mode graphics]
