Update:我找到了解决这个问题的方法，实际上它相当简单。
首先：Android的默认EGLConfigChooser实施对某些方面做出了错误的决定
设备。尤其是较旧的 Android 设备似乎会遭受这种情况EGL_BAD_MATCH问题。在调试过程中，我还发现那些较旧的麻烦制造者设备的可用 OpenGL ES 配置非常有限。
造成这种“不匹配”问题的原因不仅仅是 GLSurfaceView 的像素格式与 OpenGL ES 的颜色位深度设置之间的不匹配。总的来说，我们要解决以下几个问题：
- OpenGL ES API 版本不匹配
- 请求的目标表面类型不匹配
- 请求的颜色位深度无法在表面视图上渲染
Android 开发者文档在解释 OpenGL ES API 方面严重缺乏。因此，阅读 Khronos.org 上的原始文档非常重要。特别是关于的文档页面例如选择配置在这里很有帮助。
为了解决上述问题，您必须确保指定以下最低配置：
-
EGL_RENDERABLE_TYPE必须与您正在使用的 OpenGL ES API 版本匹配。在 OpenGL ES 2.x 的可能情况下，您必须将该属性设置为4(see egl.h)
-
EGL_SURFACE_TYPE应该有EGL_WINDOW_BIT set
当然，您还需要设置一个 OpenGL ES 上下文，为您提供正确的颜色、深度和模板缓冲区设置。
不幸的是，不可能以直接的方式挑选这些配置选项。我们必须从任何给定设备上可用的任何内容中进行选择。这就是为什么有必要实施自定义EGLConfigChooser，它会遍历可用配置集的列表，并选择与给定条件最匹配的最合适的配置集。
不管怎样，我为这样的配置选择器创建了一个示例实现：
public class MyConfigChooser implements EGLConfigChooser {
final private static String TAG = "MyConfigChooser";
// This constant is not defined in the Android API, so we need to do that here:
final private static int EGL_OPENGL_ES2_BIT = 4;
// Our minimum requirements for the graphics context
private static int[] mMinimumSpec = {
// We want OpenGL ES 2 (or set it to any other version you wish)
EGL10.EGL_RENDERABLE_TYPE, EGL_OPENGL_ES2_BIT,
// We want to render to a window
EGL10.EGL_SURFACE_TYPE, EGL10.EGL_WINDOW_BIT,
// We do not want a translucent window, otherwise the
// home screen or activity in the background may shine through
EGL10.EGL_TRANSPARENT_TYPE, EGL10.EGL_NONE,
// indicate that this list ends:
EGL10.EGL_NONE
};
private int[] mValue = new int[1];
protected int mAlphaSize;
protected int mBlueSize;
protected int mDepthSize;
protected int mGreenSize;
protected int mRedSize;
protected int mStencilSize;
/**
* The constructor lets you specify your minimum pixel format,
* depth and stencil buffer requirements.
*/
public MyConfigChooser(int r, int g, int b, int a, int depth, int
stencil) {
mRedSize = r;
mGreenSize = g;
mBlueSize = b;
mAlphaSize = a;
mDepthSize = depth;
mStencilSize = stencil;
}
@Override
public EGLConfig chooseConfig(EGL10 egl, EGLDisplay display) {
int[] arg = new int[1];
egl.eglChooseConfig(display, mMinimumSpec, null, 0, arg);
int numConfigs = arg[0];
Log.i(TAG, "%d configurations available", numConfigs);
if(numConfigs <= 0) {
// Ooops... even the minimum spec is not available here
return null;
}
EGLConfig[] configs = new EGLConfig[numConfigs];
egl.eglChooseConfig(display, mMinimumSpec, configs,
numConfigs, arg);
// Let's do the hard work now (see next method below)
EGLConfig chosen = chooseConfig(egl, display, configs);
if(chosen == null) {
throw new RuntimeException(
"Could not find a matching configuration out of "
+ configs.length + " available.",
configs);
}
// Success
return chosen;
}
/**

* our requested color, depth and stencil buffer requirements that were set using

public EGLConfig chooseConfig(EGL10 egl, EGLDisplay display,
EGLConfig[] configs) {
EGLConfig bestMatch = null;
int bestR = Integer.MAX_VALUE, bestG = Integer.MAX_VALUE,
