I am new to openGL and Android development, so please forgive me if my question is very trivial.
I am trying to create a simple small application that introduces the user from the user into three EditTexts representing 0 - 100% value for each component of the RGB color displayed in GLSurfaceView.
The trick is that I need to use openGL ES 2.0, and I need to pass the data to the shader using a single value, so that as soon as I get it working, I can go on to what I'm really trying to accomplish.
After running what I wrote, I can get GLSurfaceView to correctly display the first solid color, but whenever I change any of the values and make calls to restore a single slot in the shader, I get this error in LogCat:
ERROR / libEGL (14316): OpenGL ES API call without current context (registered once per thread)
and, of course, GLSurfaceView remains the original color.
I’ve been looking for a solution to this problem all the time, and as far as I can tell, I will need to configure EGLContext somewhere before installing my visualizer. However, I don’t see anything in the API demos about this, and the only information I can find on the Internet was written before GLSurfaceView was even available.
Do I still need to configure EGLContext or am I missing something else?
Additional information that may help:
-used XML file for customizing the user interface (and as far as I can tell about this in the code it does not help)
- the same problem occurs when I try to load a new texture from an SD card in a separate program. I can make the first texture work fine, but when using the same method to load the second, I get the same error and nothing changes.
