内でCPU情報を取得する方法を知っていますが、GPU情報を取得する方法はありますか? CPUのようなもの?
OpenGLを使用してGPU情報を取得できます。
Log.d("GL", "GL_RENDERER = " + gl.glGetString( GL10.GL_RENDERER ));
Log.d("GL", "GL_VENDOR = " + gl.glGetString( GL10.GL_VENDOR ));
Log.d("GL", "GL_VERSION = " + gl.glGetString( GL10.GL_VERSION ));
Log.i("GL", "GL_EXTENSIONS = " + gl.glGetString( GL10.GL_EXTENSIONS ));
詳細については、以下を参照してください: https://developer.Android.com/guide/topics/graphics/opengl.html
より簡単な方法:adb Shell dumpsys | grep GLES
GPU情報を取得するためのSampleActivityは次のとおりです。
public class MainActivity extends Activity implements GLSurfaceView.Renderer{
private TextView textView;
private GLSurfaceView glSurfaceView;
private StringBuilder sb;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
textView = (TextView) findViewById(R.id.textView);
final ActivityManager activityManager = (ActivityManager)getSystemService(Context.ACTIVITY_SERVICE);
final ConfigurationInfo configurationInfo = activityManager
.getDeviceConfigurationInfo();
sb=new StringBuilder();
sb.append("GL version:").append(configurationInfo.getGlEsVersion()).append("\n");
textView.setText(sb.toString());
this.glSurfaceView = new GLSurfaceView(this);
this.glSurfaceView.setRenderer(this);
((ViewGroup)textView.getParent()).addView(this.glSurfaceView);
}
@Override
public void onClick(View v) {
}
@Override
public void onSurfaceCreated(GL10 gl, EGLConfig config) {
sb.append("RENDERER").append(gl.glGetString(GL10.GL_RENDERER)).append("\n");
sb.append("VENDOR").append( gl.glGetString(GL10.GL_VENDOR)).append("\n");
sb.append("VERSION").append(gl.glGetString(GL10.GL_VERSION)).append("\n");
sb.append("EXTENSIONS").append(gl.glGetString(GL10.GL_EXTENSIONS));
runOnUiThread(new Runnable() {
@Override
public void run() {
textView.setText(sb.toString());
glSurfaceView.setVisibility(View.GONE);
}
});
}
@Override
public void onSurfaceChanged(GL10 gl, int width, int height) {
}
@Override
public void onDrawFrame(GL10 gl) {
}
}
このコードが、デバイスがGPUをサポートしているかどうかを確認します。
// Check if the system supports OpenGL ES 2.0.
final ActivityManager activityManager = (ActivityManager)getSystemService(Context.ACTIVITY_SERVICE);
final ConfigurationInfo configurationInfo = activityManager
.getDeviceConfigurationInfo();
final boolean supportsEs2 = configurationInfo.reqGlEsVersion >= 0x20000;
if (supportsEs2) {
Log.i("JO", "configurationInfo.reqGlEsVersion:"
+ configurationInfo.reqGlEsVersion + "supportsEs2:"
+ supportsEs2);
// Request an OpenGL ES 2.0 compatible context.
myGlsurfaceView.setEGLContextClientVersion(2);
final DisplayMetrics displayMetrics = new DisplayMetrics();
getWindowManager().getDefaultDisplay().getMetrics(displayMetrics);
// Set the renderer to our demo renderer, defined below.
myRenderer = new MyRenderer(this, myGlsurfaceView);
myGlsurfaceView.setRenderer(myRenderer, displayMetrics.density);
myGlsurfaceView.setRenderMode(GLSurfaceView.RENDERMODE_CONTINUOUSLY);
} else {
// This is where you could create an OpenGL ES 1.x compatible
// renderer if you wanted to support both ES 1 and ES 2.
return;
}
2番目:このコードはGPU情報を提供します。
MyRendererクラス内のこのコードに入れてください。
public void determineGraphicSupport(GL10 gl){
int _graphicEngine = GRAPHICS_CANVAS;
String extensions = gl.glGetString(GLES20.GL_EXTENSIONS);
//String version = GLES10.glGetString(GL10.GL_VERSION);
String version = GLES20.glGetString(GLES20.GL_VERSION);
//String renderer = gl.glGetString(GL10.GL_RENDERER);
String renderer = GLES20.glGetString(GLES20.GL_RENDERER);
boolean isSoftwareRenderer = renderer.contains("PixelFlinger");
boolean supportsDrawTexture = extensions.contains("draw_texture");
int[] arGlMaxTextureSize = new int[1];
gl.glGetIntegerv( GLES20.GL_MAX_TEXTURE_SIZE, arGlMaxTextureSize, 0 );
if( !isSoftwareRenderer && supportsDrawTexture && _width >= 480 && _height >= 800
&& arGlMaxTextureSize[0] >= 4096 )
_graphicEngine = GRAPHICS_OPENGL_DRAW_TEXTURE;
else
_graphicEngine = GRAPHICS_CANVAS;
}
