Set OpenGL ES version on Android (NDK)

Question

I'm following these docs and trying to set OpenGL version to 1.1. But when I call glGetString(GL_VERSION) in my C code it always returns me

OpenGL ES-CM 1.0

I believe I should specify version when I create context (or surface) but i can't find any API for this.

I'm also getting such kind of errors:

08-09 13:47:13.642: ERROR/libEGL(567): called unimplemented OpenGL ES API

which also proves that OpenGL ES 1.0 is used instead of 1.1.

Edit: I should note that on device everything is OK. The problem exists only on emulator (tested on platforms 2.2 and 2.3.3)

Edit2: tested on HTC Wildfire with Android 2.2.1 and it also shows me OpenGL version 1.0

Answer 1

The emulator only implements 1.0, so that's to be expected. You end up getting whichever version the hardware (or emulator) supports.

In the manifest you only specify what version of GLES your app requires. From the manifest guide:

Declared elements are informational only, meaning that the Android system itself does not check for matching feature support on the device before installing an application.

I should note that the emulator does implement most 1.1 features such as VBO support, so you should be ok to test your application on it anyway by making some small changes.
