Android模拟器是否支持OpenGL ES 3.0？

Question

I know that the emulator has supported OpenGL ES 2.0 as of SDK tools 17 and Android 4.0.3 , but that was introduced back in April 2012.

Does the Android emulator support OpenGL ES 3.0, or are we still waiting on that?
If not, does any other third-party emulator/simulator (eg Genymotion) support OpenGL ES 3.0?

Answer 1

The latest Android Emulator now supports OpenGL ES 3.0. To use OpenGL ES 3.0, your development machine needs a host GPU graphics card that supports OpenGL 3.2 or higher on Microsoft® Windows® or Linux.

See: https://android-developers.googleblog.com/2017/05/android-studio-3-0-canary1.html

The gles3jni sample app from the NDK is a good option to try it out.

If it fails with:

java.lang.RuntimeException: createContext failed: EGL_BAD_CONFIG

also try to run first on host:

echo "GLESDynamicVersion = on" >> ~/.android/advancedFeatures.ini

as the devs are currently whitelisting supported host GPUs, and that overrides it, see also: https://issuetracker.google.com/issues/68496715

Answer 2

Neither the Android Emulator and system images nor Genymotion currently support OpenGL ES Version 3.0.

As I write this the latest (Rev. 1) ARM and x86 system images for Android 5.1.1 (API 22) report that they support OpenGL ES Version 2.0 and not 3.0.

Similarly, Genymotion's Nexus 5 Android 5.1.0 API 22 virtual device reports only OpenGL ES Version 2.0 support.

You can use the code below to check support under future system images and emulators:

package com.example.opengltest;

import android.app.Activity;
import android.app.ActivityManager;
import android.content.Context;
import android.content.pm.ConfigurationInfo;
import android.os.Bundle;
import android.util.Log;
import android.widget.Toast;

public class OpenGLESVersionActivity extends Activity {

    private static final String TAG = "OpenGLESVersionActivity";

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        final ActivityManager activityManager =
                (ActivityManager) getSystemService(Context.ACTIVITY_SERVICE);
        final ConfigurationInfo configurationInfo =
                activityManager.getDeviceConfigurationInfo();
        String versionText = "Device Supported OpenGL ES Version = " + configurationInfo.getGlEsVersion();
        Toast.makeText(this, versionText, Toast.LENGTH_LONG).show();
        Log.d(TAG, versionText);
    }

}

Answer 3

I found the version that the emulator supported by running glGetString(GLES20.GL_VERSION) . It appears that the emulators I tested do not support OpenGL ES 3.0 or higher, but I don't want to assume that what they are reporting is what they actually support, so I'm not making any promises that this word is final.

On my Nexus 5
