您好，抱歉我的英语。
我正在Eclipse Luna Ide上用openGLES2.0开发一个Android应用程序，而OpenGL ES扩展“ GL_OES_element_index_uint”在Android模拟器中不起作用。尝试使用“ UNSIGNED_INT”类型调用“ glDrawElements”时崩溃，并显示接下来的两条错误消息。
E/emuglGLESv2_enc(764): unsupported index buffer type 5125
E/eglCodecCommon(764): **** ERROR unknown type 0x1405 (glSizeof,72)
当我通过调用“ glGetString（GL_EXTENSIONS）”请求OpenGL扩展时，它告诉我支持扩展GL_OES_element_index_uint。
为了激活GL扩展，我在渲染器类中调用了“ glEnable（GL_EXTENSIONS）”。
而且我还将下一个指令同时放在两个着色器（顶点和片段）中，以便也激活着色器中的扩展名：
#extension GL_OES_element_index_uint：启用
编译着色器的结果表明不支持此功能，正如您在我在此处发布的日志行中所见。
我不知道我做错了什么，还是模拟器的崩溃是由于与openGLES扩展程序和Android模拟器不兼容造成的
谢谢您的帮助。
这是我的日志的一部分。

最佳答案
最后，我在真实设备上运行了应用程序。我认为问题在于PC的GPU中未实现“ GL_OES_element_index_uint”扩展，因此仿真器无法将该扩展转换为HOST GPU。
如果您尝试在主机GPU中使用openGL ES扩展（OES_extensions），则该模拟器似乎无用，因为PC的GPU无法理解这些扩展。
