Writing to external SD card in Android 5.0 and above

Support Android
104

On my device, I can not format the storage as internal. :frowning:

Is excluding folders not possible too? It is greyed out in the android app.

I still wonder why it worked before the android upgrade.

105

Sadly, ignores don’t work either, as it’s written to a file in the directory, which doesn’t work if you don’t have write perms.

I have no idea why it worked before, but I guess it it should not have, and it’s not really a question we can answer.

I could create the exclude file with an editor, but it is obviously not so easy? Someone know an open source alternative, which supports external sd cards?

Damn, syncthing would be perfect. :cry:

107

You can create the file externally, it should work fine as long as syncthing can read it.

Ok, I need support for external SD cards, hope that it can be implemented in the future. :roll_eyes:

With the exclude file, I can use it temporarily.

We all need many things, sadly some things are just not meant to be. This might get fixed in android 11 supposedly, yet I am skeptical.

I know, just hoping … :thinking:

The workaround setup with three sync folders looks like this:

/storage/emulated/0/
/storage/<sd-card>/
/storage/<sd-card>/Android/media/com.nutomic.syncthingandroid/files

Excluded:

Android
...

Can watching three folders have a significance affect on speed and battery life? I need to test it anyway.

Does Syncthing work in Adaptable Storage when using the SD Card as your internal storage?

If you’re looking for a more recent Android compatibility thread.

113

Yes.

Is the storage access problem still with android 13?

It works well for me with the Syncthing-Fork app from F-Droid on Android 13:

  • One has to select every directory manually on the initial setup but read and write access is possible - also when the directory is on the SD card. No root access is required for this.
  • It may not be as fast as ever but it is fast enough. (I’ve never used Android 11 myself, only older and newer versions. However, I’ve read that Android 11 introduced a severe performance regression but it seems fixed in later Android versions.)
