Joe Bowser commented on CB-9068:
--------------------------------
I'm able to reproduce this issue on the Samsung Galaxy S5. Going to bump the
priority accordingly.

> As you can see from printed error on write fail - there is a error 6 code and
> from what I've read
> [here|https://github.com/apache/cordova-plugin-file#list-of-error-codes-and-meanings]
> it's a _NO_MODIFICATION_ALLOWED_ERR_ error.
> You can also replace _cordova.file.dataDirectory_ with any other path (i have
> tried _cacheDirectory_ and _tempDirectory_) or with a _FileSystem_ path like
> _LocalFileSystem.PERSISTENT_ (in this case you'll have to modify the
> _dirEntry.getFile_ into _dirEntry.root.getFile_ and the
> _resolveLocalFileSystemUrl_ with _requestFileSystem_ method and its
> arguments) - issue will persist!
> Am I missing some configurations/permissions or it's really a bug?
> h2. UPDATE #1
> After some more debugging time I found a possible problem.
> - on lollipop each time I try to write something to dataDirectory (or any
> other path), the system first checks for
> "/storage/sdcard1/Android/media/app.unique.id" (this is on external sdcard) -
> if it doesn't exist, then it will be created, otherwise nothing happens here.
> - in case the external sdcard is not present, then the FileWriter.write()
> will trigger the error event, *although the file will be (created and) saved
> on the specified path!*
> So, the issue after all is the error event that's been called and this, for
> me and probably others that depend on the success event, it changes the app
> behaviour.
> I have upgraded my Xperia Sola to unofficial lollipop and same thing happens.
> The Xperia Z3 Compact has the stock version on it (no root, nothing that
> could interfere with the system).
> Might this be a plugin issue or is lollipop related?
> h2. UPDATE #2
> I don't know if it's related, but here we go!
> _storage_ directory structure:
> - sdcard0 (internal memory)
> - sdcard1 (external sdcard) - empty if no external sdcard present.
> - emulated/0 (internal memory on Z3Compact / Nexus 4; same content as sdcard0
> - symlink). From what I've searched this is for multi-user purpose & app
> backward compatibility.
> From cordova-plugin-file docs:
> bq. Note: If external storage can't be mounted, the _cordova.file.external*_
> properties are null.
> With or without external sdcard, all the cordova.external.* paths link to
> sdcard0 (or emualted/0) and this happens on both kitkat and lollipop. Is it
> normal? I always thought that the cordova.external.* refers to directories
> within removable sdcard (sdcard1) and if not present then fallbacks to
> sdcard0...
> _Tested on real devices._
> h2. UPDATE #3
> Tested within Phonegap Developer App - everything works!
