Get GPU information on Android without SurfaceView

void PrettyPrintExtensions(){
 std::string extensions = (const char*) glGetString(GL_EXTENSIONS);
 char* extensionStart = &extensions[0] ;
 char** extension = &extensionStart;
 std::cout << "Supported OpenGL ES Extensions:" << std::endl;
 while (*extension)
 std ::cout <<'	' << strsep(extension, "") << std::endl;
 std::cout << std::endl;
}

On Android, is there a way to get GPU information without creating a SurfaceView? I don’t plan to use OpenGL to draw anything, but I only need to get hardware information such as vendor, OpenGL ES version, available extensions, etc.

Sorry, I don’t know how to use Android, But the function glGetString allows you to access OpenGL information. Below is a sample C style code, which will output the extensions supported by your hardware, I hope you can adapt to Android:

void PrettyPrintExtensions(){
 std::string extensions = (const char*) glGetString(GL_EXTENSIONS);
 char* extensionStart = &extensions[0];
 char** extension = &extensionStart; 
 std::cout << "Supported OpenGL ES Extensions:" << std::endl;
 while (*extension)
 std::cout <<'	' << strsep (extension, "") << std::endl;
 std::cout << std::endl;
}

By changing the parameters of glGetString, you can also access Vendor, renderer and version.
