Last night my wife's Samsung S10 could no longer access the SD card. Backcountry Navigator no longer could access the SD card either. My legacy ES File Explorer no longer works at all. Google has taken away access to the android folder. After Googleing the issue I found a site that gave a couple of file managers that would fix the issue. I downloaded both. One didn't work but Solid Explorer from the Play Store did. When I ran it I had to give permission to access the SD card & if I put in an external SD card had to give permission there too. The good news is, after doing that Backcountry Navigator had access again & all my other apps did as well EXCEPT ES Explorer which is no longer being updated so I had a feeling that someday it would no longer work. Too bad.
I hope this helps if anyone else has this issue. I have installed it on my tablet as it is android 10 & may get updated at anytime. I wanted to be ready.
Since my last post Android 11 now cuts of access to the SD card android data folder completely and no file manager can access it at this time. In addition BCN Pro can't "browse for it's own maps in it's own folders. That causes BCN Pro to crash every time. I have put in a request & to Nathan to look into this & will be anxiously waiting. We are leaving for a long hike in less than 4 weeks & need the app.
I am having something similar except that I can see and record (save) my maps but I cannot export them (says its finished exporting to /storage/9C33-6BBD/Android/data/com.crittermap.backcountrynavigator.license/data) but I cannot access or locate this. I have read somewhere that Android 11 may have changed the external storage and made it "Scoped Storage" which means that maybe BCN has lost access to see or write to my external sd. I tried to browse set the storage to a different directory but BCN does not see anything other than mnt/obb or asec (both are read only).
I have no idea what to do or how i can save and export from the external SD
I was contacted by Dan from Backcountry Navigator & they are aware of the issue & are working on a fix for it. It should be fixed in their next update so be patient. This is a Google issue. I'm directing my anger at Google for taking away the ability to control my own SD card. It doesn't belong to them. They are heading in the direction of Apple where you have no control of something you own. In case you aren't aware Google writes Android.
