You're not guaranteed GL11 so what you'll want to do is write something that happens in your Renderer.onSurfaceCreated() call. Check the GL version and then check extensions. I have a class I call GraphicsConfiguration which has a bunch of booleans of what's supported and what's not as well as the determined levels of quality/ detail to use. All of my drawing code uses the GraphicsConfiguration to get all of that info.
For instance, if GL version is 1.1 Common, VBOs are supported so you can use glBufferData. If 1.0, you have to check for vertex_buffer_object extension. If that doesn't exist, then the platform doesn't support them and you must use regular buffered arrays. I created a class to deal with that, so all I do is load data into that class and it uses VBOs or direct, depending on the capabilities defined in my GraphicsConfiguration. I also do all of my resource loading in the onDrawFrame call.
