Chris (& all) -
Now that I look at the problem more closely, I see that the local storage is
actually working (I had to reboot the phone just to make sure), but I am
getting error messages - which I originally took to mean that it wasn't.
Here is the code that is failing. The message I'm getting is 'Failed to create
options file: undefined' - that is coming from _errorHandler:
//--save options struct to file
saveOptions = function (_options) {
var
_fileWriter,
_errorHandler = function (_evt) {
alert('Failed to create options file: ' + _evt.name);
},
_getFileSuccess = function (_fileEntry) {
_fileEntry.createWriter(_writeFile, _errorHandler);
},
_onWriteEnd = function () {
_fileWriter.onwriteend = undefined;
if ('undefined' === typeof window.cordova) {
//--for Chrome
_fileWriter.write(new
Blob([JSON.stringify(_options)], {type: 'text/plain'}));
} else {
//--for PhoneGap
_fileWriter.write(JSON.stringify(_options));
}
},
_writeFile = function (_fw) {
_fileWriter = _fw,
_fileWriter.onerror = _errorHandler;
_fileWriter.onwriteend = _onWriteEnd;
_fileWriter.truncate(0);
};
if ('undefined' === typeof dirEntry) {
if ('undefined' !== typeof window.cordova) {
alert('Failed to access file system to save options');
}
return;
}
But, like I said the app is actually saving its current state and picks up
where it left off even after reboot. So it looks like the error handler is
being called promiscuously?
BTW, do you know off-hand how to access local files on the Flame device. I
installed a file manager from the app store which did precisely nothing (just
showed sdcard and external storage as being empty) and remote access from my pc
doesn't achieve much more. On android devices I use ES File Manage just to have
a look at the contents of the saved file.
Regards,
William

Ah, so we do support the File API - that’s good news.
Any thoughts on William’s specific problem? William, perhaps you could point us
to a code sample so we can see if we can see what’s up with it?
