Question

Here’s my code so far:

String path = Environment.getExternalStorageDirectory().toString()+"/Pictures";

        AssetManager mgr = getAssets();

        try {

            String list[] = mgr.list(path);
            Log.e("FILES", String.valueOf(list.length));

            if (list != null)
                for (int i=0; i<list.length; ++i)
                    {
                        Log.e("FILE:", path +"/"+ list[i]);
                    }

        } catch (IOException e) {
            Log.v("List error:", "can't list" + path);
        }

Yet while I do have files in that dir, it returns me list.length = 0… any ideas?

In order to access the files, the permissions must be given in the manifest file.

<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />

Try this:

String path = Environment.getExternalStorageDirectory().toString()+"/Pictures";
Log.d("Files", "Path: " + path);
File directory = new File(path);
File[] files = directory.listFiles();
Log.d("Files", "Size: "+ files.length);
for (int i = 0; i < files.length; i++)
{
    Log.d("Files", "FileName:" + files[i].getName());
}
