------------------------------------------

[~decagon], I believe this is an application/WebView issue related to the {{Blob}} constructor and here is a workaround:

Let me know if this helps.

> I'm trying to create and write to a file in cordova.file.dataDirectory
> (file:///data/data/<package name>/files/) or cordova.file.cacheDirectory.
> But without success on android 4.4.2 .
> The code fails on :
> or using : 
> fs.root.getFile("myfile.txt", { create: true, exclusive: false }, function () {}, function () {});
> Example of code :
> window.resolveLocalFileSystemURL(cordova.file.dataDirectory,
> 	function (directoryEntry) { // success
> 		directoryEntry.getFile('myfile.txt', { create: true },
> 			function (fileEntry) { //success
> 				fileEntry.createWriter(
> 					function (fileWriter) { // success
> 						fileWriter.onwriteend = function () {
> 							console.log("OK");
> 						};
> 						fileWriter.onerror = function (e) {
> 							console.log("Not OK");
> 						};
> 						// If data object is not passed in,
> 						// create a new Blob instead.
> 						if (!data) {
> 							data = new Blob([' '], { type: 'text/plain' });
> 						}
> 						data = JSON.stringify(data);
> 						var blob = new Blob([data], { type: 'text/plain' });
> 						fileWriter.write(blob);
> 					},
> 					function (e) { // error
> 						console.log(e);
> 					}
> 				);
> 			},
> 			function (e) { // error
> 				console.log(e);
> 			}
> 		);
> 	},
> 	function (e) { // error
> 		console.log(e);
> 	}
> );
> directoryEntry.getFile doesn't work.
> However, it works on Android 6
