如何在android sceneform sdk运行时从URL加载.obj文件

dependencies {
    // ...
    implementation 'com.google.ar.sceneform.ux:sceneform-ux:1.17.1'
}

<fragment
    android:id="@+id/arFragment"
    android:name="com.google.ar.sceneform.ux.ArFragment"
    android:layout_width="match_parent"
    android:layout_height="match_parent" />

ArFragment arFragment = (ArFragment) getSupportFragmentManager().findFragmentById(R.id.arFragment);
arFragment.setOnTapArPlaneListener((hitResult, plane, motionEvent) -> {
    // 创建一个Renderable对象
    ModelRenderable.builder()
        .setSource(this, Uri.parse("URL_TO_OBJ_FILE"))
        .build()
        .thenAccept(renderable -> {
            // 在点击的位置添加3D模型
            Anchor anchor = hitResult.createAnchor();
            AnchorNode anchorNode = new AnchorNode(anchor);
            anchorNode.setParent(arFragment.getArSceneView().getScene());
            TransformableNode model = new TransformableNode(arFragment.getTransformationSystem());
            model.setParent(anchorNode);
            model.setRenderable(renderable);
            model.select();
        })
        .exceptionally(throwable -> {
            // 加载失败的处理
            Toast.makeText(this, "无法加载模型", Toast.LENGTH_SHORT).show();
            return null;
        });
});
