There are lots of Android devices around the world. And when you want to create one application that need OpenGL ES, you would think (what I thought) if the user's device can run smoothly by checking the OpenGL ES version because this is important.
So how to check the OpenGL ES version?
- By using SystemService. This is the simplest one. You don't need to create any OpenGL ES component.
final ActivityManager activityManager = (ActivityManager) getSystemService(Context.ACTIVITY_SERVICE);
final ConfigurationInfo configurationInfo = activityManager.getDeviceConfigurationInfo();
final boolean supportsEs2 = configurationInfo.reqGlEsVersion >= 0x30000; - By using glGetService. By doing this, you can get more information, like the vendor, chip, shading version, etc. But, you need to have GL context first.
String glVersion = GLES20.glGetString(GLES20.GL_VERSION);
String glRenderer = GLES20.glGetString(GLES20.GL_RENDERER);
String glVendor = GLES20.glGetString(GLES20.GL_VENDOR);
String glShadingLanguageVersion = GLES20.glGetString(GLES20.GL_SHADING_LANGUAGE_VERSION);
String glExtensions = GLES20.glGetString(GLES20.GL_EXTENSIONS);
