OsmAnd will import map files from a file:// URL pointing to an OBF file, but this currently only works for file:// and not the proper content://. This uses a hack to disable the warning about file:// URIs but only for the final stage of installing the .obf file. Hopefully in the future, this can be changed to use a proper content:// URL as I suggested to them in this merge request: https://github.com/osmandapp/OsmAnd/pull/10043
