问题
I have search the forum and cant find exact answer for these.
Every time I compile and run the app. There is an error
Emulator: OpenGL backend 'angle' without OpenGL ES 1.x library detected. Using GLESv2 only.
However, everything still run smoothly, and thus I didn't bother.
So, what is the correct approach to this?
- To update the library.
- To ignore it since it is just outdated but usable.
- What are the benefit of updating
Refer Android OpenGL ES 2.0 emulator
I found out that there are a few questions like this remain unanswered. Thus Anyone please give a suggestion so other will know what to do.
回答1:
Angle is an open-source project that implements OpenGLES over DirectX/Desktop OpenGL. That is, it takes OpenGLES commands, and converts them to something that can run easily on desktop machines.
It's likely that the Android emulator would use a technology like Angle to convert your project's OpenGLES commands and possibly the Android OS OpenGLES commands to DirectX/Desktop OpenGL.
The error is telling you that the Angle library lacks the OpenGLES 1.x component. I'm not sure if it's a normal situation or not - if it is an error, it's a problem with the emulator, not with your code. If everything appears to be working correctly then I wouldn't worry about it. Most likely the emulated OS and your project are using OpenGLES 2 or 3, or if you are using OpenGLES 1.x, then perhaps there's a compatibility layer that implements OpenGLES 1.x over OpenGLES 2 before anything gets passed to Angle.
