Error loading ENC layer: Invalid argument.

[MaríaBencomo]

Hi,

I'm facing this problem.. i have my ENC charts in this path /storage/emulated/0/Android/data/com.example.enc_pt/cache/charts/VE300600/ENC_ROOT. When i'm trying to loading it, i got this error:  Error loading ENC layer: Invalid argument.

In the image you can see i got bot files .000 and .031.

This how i load it:

Any help would be appreciate.

Maria.

private void loadEncExchangeSet(List<String> folders) {
    Log.d("EncLoader", "Loading folders into ENC Exchange Set...");
    /*for (String folder : folders) {
        Log.d("EncLoader", "→ " + folder);
    }*/

    String pa = "/storage/emulated/0/Android/data/com.example.enc_pt/cache/charts/VE300600/ENC_ROOT/CATALOG.031";

    List<String> p = Collections.singletonList(pa);

    //mEncExchangeSet = new EncExchangeSet(folders);
    mEncExchangeSet = new EncExchangeSet(p);
    mEncExchangeSet.loadAsync();

    mEncExchangeSet.addDoneLoadingListener(() -> {
        if (mEncExchangeSet.getLoadStatus() == LoadStatus.LOADED) {
            // add each data set's Enc cell as an ENC layer
            for (EncDataset encDataset : mEncExchangeSet.getDatasets()) {
                // create an ENC layer with an ENC cell using the dataset
                EncLayer encLayer = new EncLayer(new EncCell(encDataset));
                // add the ENC layer to the map's operational layers
                mMapView.getMap().getOperationalLayers().add(encLayer);
                encLayer.addDoneLoadingListener(() -> {
                    if (encLayer.getLoadStatus() == LoadStatus.LOADED) {
                        Envelope extent = encLayer.getFullExtent();
                        // combine extents of each layer
                        if (mCompleteExtent == null) {
                            mCompleteExtent = extent;
                        } else {
                            mCompleteExtent = GeometryEngine.combineExtents(Arrays.asList(mCompleteExtent, extent));
                        }
                        // set the view point to the extent of all enc layers
                        mMapView.setViewpointAsync(new Viewpoint(mCompleteExtent));
                    } else {
                        Log.d("EncLoader", "Error loading ENC layer: " + encLayer.getLoadError().getMessage());

                    }
                });
            }
        } else {
            String error = "Error loading ENC exchange set: " + mEncExchangeSet.getLoadError().getMessage();
            Toast.makeText(this, error, Toast.LENGTH_LONG).show();
            Log.e(TAG, error);
        }
    });
}

Hey @MaríaBencomo 

Would it be because you're referencing the file directly? You may need to put this:

String pa = "/storage/emulated/0/Android/data/com.example.enc_pt/cache/charts/VE300600/ENC_ROOT";

To my knowledge it would be directory access rather than direct file access, but I would also make sure that you have correct permissions to access the folder.
