x/mobile: Android Storage Access Framework support

[Nutomic]

On Android Kitkat and higher, the Storage Access Framework is the only way to read/write files on an external SD card (eg /storage/sdcard1/).

However, access to that is handled through URIs like this:

content://com.android.providers.media.documents/document/image:62

These URIs can't easily be converted to paths [1]. We need this for syncthing-android, and have discussed this already [2] [3].

Go Version: 1.4.2
OS: Android, any architecture

is there any reason why it's unplanned? currently there is not any other way on android to use external storage!?

Unplanned means we want to do it, but have not found the programmer hours to do it. We are not a large team.

i think, syncthing android is useless, without access to sdcard.

bittorrent sync is able to sync the pictures of my phone (sony xperia z3 on lolipop) to all my windows clients and i really want to get rid of it.

Any progress? It's been almost a year since this was reported. Access to the SD card is an extremely important feature.

Are there any news on that?

Guys, any new on that? Its an Important Feature :-(

[fti7]

@crawshaw do you accept bounties for that Issue? Maybe we can sponsor the "Programmer Hours" somehow?

[urza]

This is really a very important feature! I will also donate few dollars if needed..

[AudriusButkevicius]

How could this be implemented though?
As far as I understand, it's impossible without tapping into the NDK, hence adding a mandatory cgo dependency?

For me I solved it with marshmallow release. I extend the space to the sdcard. So I have 70 sth gig on my S5.
But it does notsolve it for Lollipop releases.
