Android emulator crashes when trying to use gl extension "GL_OES_element_index_uint"

Hello and sorry for my english.

I'm developing an Android app with openGLES2.0 on Eclipse Luna Ide, and the OpenGL ES extension "GL_OES_element_index_uint" doesn't work in the Android emulator. It crashes when trying to call "glDrawElements" with "UNSIGNED_INT" type and shows the next two error messages.

E/emuglGLESv2_enc(764): unsupported index buffer type 5125
E/eglCodecCommon(764): **** ERROR unknown type 0x1405 (glSizeof,72)

When I request the OpenGL extensions with a call to "glGetString(GL_EXTENSIONS)" it tells me that the extension GL_OES_element_index_uint is supported.

I've made a call to "glEnable(GL_EXTENSIONS)" in the renderer class in order to activate the GL extensions.

And I've also put the next directive in both shaders (vertex and fragment), in order to activate the extension in the shaders too: #extension GL_OES_element_index_uint : enable

and the result of compiling the shaders says that this feature is not supported, as you can see in the log lines I've post down here.

I don't know if I'm doing anything wrong or the emulator's crash is due to incompatibilities with the openGLES extensions and the Android emulator

Thank you for your help.

Here is an extract of my log.

Finally I got the app runnig on a real device. I think that the problem was that the "GL_OES_element_index_uint" extension isn't implemented in the PC's GPU, so the emulator can't translate that extension to the HOST GPU.

It seems that the emulator is useless if you are trying to use openGL ES extensions (OES_extensions) in the host GPU, because PC's GPU can't understand those extensions.
