Sergey Shakhnazarov commented on CB-10960:
------------------------------------------
Reproduced the issue, investigating.
Note that the [Blob constructor
polyfill|https://github.com/MobileChromeApps/mobile-chrome-apps/commit/f4f884ffbf7af1c30b9da559f8afbccbca0bb151]
is required (at least for Android 4.3) to avoid the following error:
{noformat}
I/Web Console(10809): Error in Success callbackId: File82774416 : TypeError:
Illegal constructor:312
E/Web Console(10809): Uncaught TypeError: Illegal constructor:314
{noformat}
> Uncaught #<FileError> in write() when readyState != WRITING ?

> Key: CB-10960
> URL: https://issues.apache.org/jira/browse/CB-10960
> Project: Apache Cordova
> Issue Type: Bug
> Components: Plugin File
> Affects Versions: 4.1.1
> Environment: Android
> Reporter: Samo Dadela
> Labels: android
> Attachments: code.js
>
>
> Excuse me if I did something stupid - I'm new to Cordova and JS.
> I thought that calling write() after checking readyState != WRITING would
> work.
> {code}
> function writeQueue(c) {
> while ( !(logWriter.readyState === FileWriter.WRITING) ) {
> var msg = logQueue.dequeue();
> if (!msg) {
> return;
> }
> var blob = new Blob([msg+c], { type: 'text/plain' });
> logWriter.write(blob);
> }
> }
> }
> {code}
> But I get:
> 0 277161 log log writer: cdvfile://localhost/files/bala.log
> 1 277199 log log writer: onwriteend
> 2 283616 log log writer: onwriteend
> 3 283629 log log writer: onwriteend
> 4 283651 error Uncaught #<FileError>,
> http://192.168.1.200:8100/plugins/cordova-plugin-file/www/FileWriter.js,
> Line: 130
> Line 130 is:
> {code}
> // Throw an exception if we are already writing a file
> if (this.readyState === FileWriter.WRITING) {
> throw new FileError(FileError.INVALID_STATE_ERR);
> }
> {code}
> How can readyState change to WRITING ?
> Note: Queue is pure Javascript
