Phonegap / Cordova API Delete files when deleting

Question

I am creating a Phonegap / Cordova application that downloads some files and saves them on the device. For this, I use the file API.

window.requestFileSystem(LocalFileSystem.PERSISTENT, 0, function (fileSystem) { rootPath = fileSystem.root.fullPath; }, fail ); 

On iOS, this will install rootPath in the application’s private directory, which is good. On Android, this will install rootPath in the root folder of the external storage, which is a problem because these files are not attached to the application and are not deleted when the application is deleted. As far as I understand, the correct way to do this on Android would be to use getExternalFilesDir . How can I get getExternalFilesDir functionality via Phonegap?

Answer 1

You want to request a directory of external files through JS.

 window.requestFileSystem(LocalFileSystem.PERSISTENT, 0, function (fileSystem) { fileSystem.root.getDirectory("Android/data/com.my.app/files", {create: true, exclusive: false}, function(dirEntry) { rootPath = dirEntry.fullPath; }, fail);; }, fail ); 

Now you have a path pointing to the area that will be cleared when the application is uninstalled.

You cannot track the delete event. but to remove the directory is the code below.

 function deleteDirectory(directoyName){ $scope.fs.root.getDirectory(directoyName,{ create: false, exclusive: false }, function(dirEntry) { dirEntry.removeRecursively(function() { console.log('Directory Successfully Removed.'); }, errorHandler); }, errorHandler); }
