There's a 128-character limit on these devices: see notes in importer.py. This could probably be worked around by altering resource_loader.get_path_to_datafile, which is already in our TensorFlow patch. It's probably better not to call the importer's internal API directly because that would mean we can't change that API without breaking existing wheels. Copy the code instead.

When this is fixed, post an update at #228.

We're unlikely to update TensorFlow in the near future (#374 (comment)), and we'll also be increasing the minimum API level to 23 soon (#718).
