Good intentions of Osmand to install on extern memory is prevented in
this way.
Is there a way to at least force Offline data to a user choosen dir?
FS File Explorer could copy the osmand dir. Then renamed the original
dir to osmandx and restarted Osmand. This worked.
Then went to osmand.net and downloaded and installed the latest build.
This runs ok keeping the new dir.
All solved. Thanks.
