Gave it a go saving to another location to see if it would get around that
permission, seems like saving to the app data directory
`cordova.file.dataDirectory` works.
`fileSystem.root` seems to be outside of the app data perhaps? - I didn't
realise this since the docs say "fs.root is a DirectoryEntry object that
represents the persistent storage in the sandboxed file system."
Also noticed the following when trying out some options:
- If the file was created by the API 28 app, the API 29 app seems to be able
to write to it, it just can't create new files.
- Using `requestFileSystem(window.TEMPORARY` seems to work.
In case it's useful for anyone else that only needs to store files in the
app dir, the change to use `cordova.file.dataDirectory` is:
```js
window.resolveLocalFileSystemURL(cordova.file.dataDirectory, // <-----------
function (dirEntry) { // <-----------
dirEntry.getFile("test2.txt", {create: true, exclusive: false},
// <-----------
function(fileEntry) { // File loaded/created
fileEntry.createWriter(
function(writer) { // Writer
created
writer.write('hello');
console.log('test2 it worked!');
},
function(error) { // Writer
failure
console.log('createWriter',
error);
}
);
},
function(error) { // File failure
console.log('getFile', error);
}
);
},
function(error) { console.log('resolveLocalFileSystemURL', error); }
);
```
