Question

我想在ARcore中渲染文件（andy.sfb）。可以从https://和file://获取此文件。传统上，将file：//分配给资产文件夹中的文件，该文件夹与应用程序打包在一起。但是，目的是下载3D模型，然后从本地设备存储中给出路径（ URI ），这可能类似于/storage/emulated/0/Download/andy.sfb。 SFB 代表SceneForm Binary。

我的挑战一直是从本地设备存储中呈现模型运行时。问题在detail

中显示

  File file = new File("file:///storage/emulated/0/Download/andy.sfb");
            Callable callable = () -> {
            InputStream inputStream = new FileInputStream(file);
            return inputStream;
        };
        FutureTask task = new FutureTask<>(callable);
        new Thread(task).start();

        ModelRenderable.builder()
            .setSource(this, callable)
                .build()
                .thenAccept(renderable -> andyRenderable = 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;
                        });

您可以将.sfb文件从服务器下载到本地存储，然后加载该.sfb文件。要从本地存储加载对象，请使用以下代码：

ModelRenderable.builder()
            .setSource(this, Uri.fromFile(new File(path + fileName)))
            .build()
            .thenAccept(renderable -> {
                andyRenderable = 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;
                    });

如何在运行时从本地存储导入SFB文件？
