尝试使用gl扩展程序时，Android模拟器崩溃了＃34; GL_OES_element_index_uint＆＃34;

您好，对不起我的英语。

我正在Eclipse Luna Ide上开发一个带有openGLES2.0的Android应用程序，以及OpenGL ES扩展＆＃34; GL_OES_element_index_uint＆＃34;不能在Android模拟器中工作。当试图调用＆＃34; glDrawElements＆＃34;它时会崩溃。使用＆＃34; UNSIGNED_INT＆＃34;输入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＆＃34; glGetString（GL_EXTENSIONS）＆＃34;来请求OpenGL扩展时它告诉我支持扩展GL_OES_element_index_uint。

我打电话给＆＃34; glEnable（GL_EXTENSIONS）＆＃34;在渲染器类中，以激活GL扩展。

我还将下一个指令放在两个着色器（顶点和片段）中，以便在着色器中激活扩展：  #extension GL_OES_element_index_uint：启用

并且着色器的编译结果表明不支持此功能，您可以在我在此处发布的日志行中看到。

我不知道我做错了什么或模拟器崩溃是由于与openGLES扩展程序和Android模拟器不兼容

感谢您的帮助。

以下是我的日志摘录。

答案 0 :(得分：2)

最后我在真实设备上运行了app runnig。我认为问题在于＆＃34; GL_OES_element_index_uint＆＃34;扩展并未在PC的GPU中实现，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），仿真器似乎毫无用处，因为PC的GPU无法理解这些扩展。
