I've used Dropbox for years now. Love it on PC and between PC's. Access to those PC files from my phone has been so useful too.
This week for the first time I wanted to add a Dropbox folder where I can save files that I've made on my phone - (1) to have them backed up in the cloud and (2) to access them easily by PC too. As a specific example, I want to use a voice recorder app to save short *.mp3 memos.
Using my PC, I created a folder for them in my Dropbox. On my phone, I set the folder to be available offline.
On the phone, I have two File-Manager type apps, Solid Explorer (SE) which is pretty comprehensive and Google Files (GF) which is more basic. I looked for folders starting at the root of 'Internal Storage':
- In GF, I can see \Android and \Android\Data folders. When I open the latter, GF tells me "There's nothing here"
- in SE, I can see the same folders; there's lots of stuff under \Android\Data, including com.dropbox.android; but when I open this SE tells me "No content here'
In my Voice Recorder app Easy Voice Recorder (EVR), I can browse within Internal Storage to set the location to save files. \Android is listed, but when I open it I get a message "Can't use this folder", and the folder \Android\Data isn't listed. Nothing under \Android is listed except \Android\Media. It will let me set, for example, \Music or \Movies or \Documents as the file location but not \Downloads.
Now, I don't know Android except as a user but for my sins long ago, I have a Comp Sci degree. I cannot see or work out how to have a simple folder, in the way I'm used to on the PC, which is accessible to my Android apps but which is also backed up / mirrored by Dropbox. What am I missing? I'm frustrated that Google's OS is so opaque and hard-to-use - these apps seem to have folder-by-folder permissioning the management of which is completely invisible to me... you know, only the guy who's paying for and using the device.
How can I set up a Dropbox-sync'd folder between Phone and PC that's accessible to my Android apps? Where in the Android file tree can I find the Dropbox folders that I've set to be 'Available Offline'? How can I give, say, EVR access to more file folders? They're my effin' folders, right?
