OpenGL ES 2.0 对 Android 的支持? [英] OpenGL ES 2.0 Support for Android?

问题描述

Android 模拟器是否支持 OpenGL ES 2.0?我看到有些人说是的，但你必须更改一些设置."我也看过不，它不支持它，句号."以下是我为尝试纠正问题所做的工作，包括我收到的一些错误消息.

Does the Android emulator support OpenGL ES 2.0? I've seen some people say "Yes, but you have to change a few settings." and I've also seen "No, it doesn't support it, period." Here's what I've done to try and correct the problem, including some error messages that I got.

首先，我修改了 AndroidManifest.xml 以包含以下代码:

First, I modified the AndroidManifest.xml to contain the following code:

<uses-feature 
    android:glEsVersion="0x00020000" />

<uses-sdk
    android:minSdkVersion="15"
    android:targetSdkVersion="17" />

然后，当我想实例化我的 GLSurfaceView 时，我使用以下代码序列来实例化它:

Then, when I want to instantiate my GLSurfaceView, I use this sequence of code to instantiate it:

super(context);

setEGLContextClientVersion(2);

setRenderer(new MyRenderer());
setRenderMode(GLSurfaceView.RENDERMODE_WHEN_DIRTY);

然后，我到处都说你必须进入 AVD 管理器，选择模拟器，进入硬件"，添加GPU 仿真"并将布尔值设置为是".然而，当我看到我的时，这是我看到的:

Then, everywhere I looked said that you must go into the AVD Manager, select the emulator, go to "Hardware", add "GPU emulation" and set the boolean to "yes". However, here is what I see when I look at mine:

奇怪的是，我的 AVD 管理器中有另一个模拟器，其中有硬件"表:

What's peculiar is that I have another emulator in my AVD Manager of which I do have the "Hardware" table:

为了准确地向您展示我在做什么，这里有一些代码可以做一些我想在 OpenGL ES 2.0 中做的事情(我主要是从 Android 自己的教程中得到的):

And just to show you exactly what I'm doing, here's some code that does some stuff I want to do in OpenGL ES 2.0 (I mainly got this from Android's own tutorials):

int vertexShader = loadShader(GLES20.GL_VERTEX_SHADER, vertexShaderCode);
int fragmentShader = loadShader(GLES20.GL_FRAGMENT_SHADER, fragmentShaderCode);

program = GLES20.glCreateProgram();
GLES20.glAttachShader(program, vertexShader);
GLES20.glAttachShader(program, fragmentShader);
GLES20.glLinkProgram(program);

我不想将我的代码改回使用 OpenGL ES 1.0，因为这需要很多麻烦，如果我能避免它，我会的.

I don't want to change my code back to work with OpenGL ES 1.0 because that will require a lot of headaches and if I can avoid it, I will.

最后，当我尝试运行我的程序时，程序关闭并显示以下窗口:不幸的是，已停止."这是 LogCat 告诉我的:

Finally, when I try running my program, the program closes with the window: "Unfortunately, has stopped." This is what LogCat told me:

12-05 06:16:27.165: E/AndroidRuntime(936): FATAL EXCEPTION: GLThread 81

推荐答案

我可以回答你的问题.Android 模拟器支持 OpenGL ES 2.0.我用 cocos2d-x v.2(它使用 OpenGL ES 2.0)创建了一个应用程序.我有同样的 FATAL EXCEPTION: GLThread 81 error with same stack.我通过添加解决了这个问题

I can say Yes on your question. Android emulator supports OpenGL ES 2.0. I created an app with cocos2d-x v.2 (which uses OpenGL ES 2.0). I had same FATAL EXCEPTION: GLThread 81 error with same stack. I solved this issue by adding

gLSurfaceView.setEGLConfigChooser(8 , 8, 8, 8, 16, 0);

设置渲染器之前 setRenderer:

before setting renderer setRenderer:

gLSurfaceView.setCocos2dxRenderer(new Cocos2dxRenderer());

现在我可以在 Android 模拟器上运行我的应用了.

Now I can run my app on Android emulator.
