java.lang.NoSuchMethodError : No virtual method setUpdateMode while trying to render a Sceneform object

Question

我对增强现实和 ARCore 都很陌生。我正在尝试渲染场景对象，但应用程序总是崩溃并给出此错误。

java.lang.NoSuchMethodError: No virtual method setUpdateMode(Lcom/google/ar/core/Config$UpdateMode;)V in class Lcom/google/ar/core/Config; or its super classes (declaration of 'com.google.ar.core.Config' appears in /data/app/com.example.firstar-73MXMhLuPjkwTp19W2ZiSQ==/base.apk)

这是我的代码:

public class MainActivity extends AppCompatActivity {

    ArFragment arfrag=new ArFragment();
    ModelRenderable andyRenderable;
    private static final double MIN_OPENGL_VERSION = 3.0;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        setContentView(R.layout.activity_main);

        arfrag = (ArFragment) getSupportFragmentManager().findFragmentById(R.id.ARfrag);

        arfrag.setOnTapArPlaneListener(
                (HitResult hitResult, Plane plane, MotionEvent motionEvent) -> {
                    if (andyRenderable == null) {
                        return;
                    }
                    Anchor anchor = hitResult.createAnchor();
                    ModelRenderable.builder()
                            .setSource(this, Uri.parse("arfox.sfa"))
                            .build()
                            .thenAcceptAsync(renderable -> addObject(anchor, renderable))
                            .exceptionally(
                                    throwable -> {
                                        Toast toast =
                                                Toast.makeText(this, "Unable to load andy renderable", Toast.LENGTH_LONG);
                                        toast.setGravity(Gravity.CENTER, 0, 0);
                                        toast.show();
                                        return null;
                                    });

                    // Create the Anchor.


                });

    }

    private void addObject(Anchor anchor,ModelRenderable model) {

        AnchorNode anchorNode = new AnchorNode(anchor);
        TransformableNode andy = new TransformableNode(arfrag.getTransformationSystem());
        andy.setParent(anchorNode);

        andy.setRenderable(model);
        arfrag.getArSceneView().getScene().addChild(anchorNode);
        andy.select();


    }
}

我获得了所需的相机权限，并添加了 ARcore 和 Sceneform 工作所需的依赖项，但应用程序在运行时崩溃。很高兴知道此错误背后的原因。

谢谢。

检查应用程序 build.gradle 中是否定义了以下选项:

compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }
