Grib_pi Android download not working #1310

In trying to downlaod grib files with grib_pi I find download no longer works. Probably because the established path for downloads is no longer permitted.
This probably reqiures user to edit config file. Not easy to do on andriod, and to pick an accessible directory and perhaps make a grib folder.

I consider grib pi broken for most users. This is too much for them to deal with.
I find it very disappointing that Andriod keeps changing basic security settings. This has broken a number of sailing apps for me.
