Load .sfb file from Device Storage

[ltthuc1989]

Hi develop team! I can create .sfb file by using "com.google.ar.sceneform.plugin".So I want to copy these file into my android storage folder.These code is for rendering 3D model from assets folder. CompletableFuture sunStage = ModelRenderable.builder().setSource(this, Uri.parse("Sol.sfb")).build(); How can i load 3D file from my own folder and render them in my app?.Thanks

Hi @ltthuc1989 - thanks for the question!

To load from external storage, you'll want to use a file URI. You can build one of these from any java.io.File using the Uri.fromFile() api. Finally, in order to get a file that references your Android storage folder, you'll want to use one of the related external storage Android apis such as [Environment.getExternalStorageDirectory()](https://developer.android.com/reference/android/os/Environment#getExternalStorageDirectory())

@tpsiaki Hi. I created File, check file - it exist. But I get all time Unable to load Renderable registryId='file:///storage/emulated/0/Download/lion3.sfb' java.util.concurrent.CompletionException: java.io.FileNotFoundException: /storage/emulated/0/Download/lion3.sfb

String strSfb = "/storage/emulated/0/Download/lion3.sfb"; File file = new File(strSfb); file .exists() //=true {addObject(Uri.fromFile(file));}

Hi @tpsiaki ! When i create 3D model with material file by using "com.google.ar.sceneform.plugin". It will automatic read material file from "sampledata" folder data then write these material path into .sfb file .these meterial path like this: samplers: [ { file: "sampledata/models/Sol/Sol_Transparent_Mat_baseColor.png", name: "Sol_Transparent_Mat_baseColor", pipeline_name: "Sol_Transparent_Mat_baseColor.png", }, { file: "sampledata/models/Sol/SolarFlare_Transparent_Mat_baseColor.png", name: "SolarFlare_Transparent_Mat_baseColor", pipeline_name: "SolarFlare_Transparent_Mat_baseColor.png", }, { file: "sampledata/models/Sol/SolarFlare_Transparent_Mat_emissive.png", name: "SolarFlare_Transparent_Mat_emissive", pipeline_name: "SolarFlare_Transparent_Mat_emissive.png", }, { file: "sampledata/models/Sol/Sol_Opaque_Mat_baseColor.png", name: "Sol_Opaque_Mat_baseColor", pipeline_name: "Sol_Opaque_Mat_baseColor.png", }, { file: "sampledata/models/Sol/Sol_Transparent_Mat_emissive.png", name: "Sol_Transparent_Mat_emissive", pipeline_name: "Sol_Transparent_Mat_emissive.png", }, { file: "sampledata/models/Sol/Sol_Opaque_Mat_emissive.png", name: "Sol_Opaque_Mat_emissive", pipeline_name: "Sol_Opaque_Mat_emissive.png", }, ], .I mean that if i put these material file into my Device Storage (storage/emuated/0/Download/app_folder/model/Sol/....) and .sfb file (....../Download/app_folder/sfb/...) .So i have to using text editor to edit sfb file one by one to change material file path(file: "sampledata/models/Sol/Sol_Opaque_Mat_baseColor.png )to (file:storage/emuated/0/Download/app_folder/model/Sol/..) is that right?thanks

@ltthuc1989 - the file paths referenced in the .sfa file are only used to build the .sfb file on your development machine. The content in these files is bundled into the .sfb file, and the .sfb file is the only artifact used at runtime. This is why we recommend that you place models in the sampledata folder since that folder is not bundled into your apk.

So, you should leave the file paths in the .sfa pointing at the locations of the corresponding files on your development machine, and then build the .sfb. Then place the .sfb in your device storage, and you should be able to load the .sfb directly from there.

Hi @tpsiaki ! i have got it.Thank so much :-)

@ldima The URI based file loading isn't looking at external storage. Right now it's only looking for application assets using file:// and remote uris starting with http://

We will track this issue at https://github.com/google-ar/sceneform-android-sdk/issues/79

you can load .sfb file from sdcard like this: // sdcard File file = new File("/storage/emulated/0/ar/model.sfb"); Callable callable = new Callable() { @Override public InputStream call() throws Exception { 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;
                    });

@scolar can you please update it.... i tried this but my app is crashing. i have checked for file.exists() and it returned true so the file is there.

thanks

I'm downloading my models this way:

fun downloadFile(downloadSFB: String) {
        var downloadManager: DownloadManager

        downloadManager = getSystemService(Context.DOWNLOAD_SERVICE) as DownloadManager
        val uri = Uri.parse(downloadSFB)
        val request = DownloadManager.Request(uri)
        request.setNotificationVisibility(DownloadManager.Request.VISIBILITY_VISIBLE_NOTIFY_COMPLETED)
        request.setDestinationInExternalFilesDir(this,Environment.DIRECTORY_DOWNLOADS, "andy.sfb")
        val reference = downloadManager.enqueue(request)
    }

after downloading I'm showing it as:

var fileX = File("storage/emulated/0/Android/data/com.gathergood.calum.ardemo/files/Download/andy.sfb");

        var callable: Callable<InputStream> = Callable<InputStream> {
            FileInputStream(fileX);
        }
        ModelRenderable.builder()
                .setSource(applicationContext, callable)
                .build()
                .thenAccept {
                    currentModelRenderable = it
                }
                .exceptionally {
                            Toast.makeText(this, "Unable to load andy renderable", Toast.LENGTH_LONG).show();
                            return@exceptionally null

                }

                            return@exceptionally null

                }

I tried all this...But it cant render the model...app is working fine...but It cant load the model from local storage.
