[ https://issues.apache.org/jira/browse/CB-4850?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Jesse MacFadyen resolved CB-4850.
---------------------------------
Resolution: Fixed
> Write the device UUID only when it does not exist
> -------------------------------------------------
>
> Key: CB-4850
> URL: https://issues.apache.org/jira/browse/CB-4850
> Project: Apache Cordova
> Issue Type: Improvement
> Components: WP7, WP8
> Affects Versions: 3.0.0
> Environment: Any
> Reporter: Jonathan Naguin
> Assignee: Jesse MacFadyen
> Priority: Minor
>
> Currently, the device UUID is writen back to the IsolatedStorageFile in every run even when it is not necessary.
> On CordovaView.xaml.cs:
> {code}
> string deviceUUID = "";
> using (IsolatedStorageFile appStorage = IsolatedStorageFile.GetUserStoreForApplication())
> {
> try
> {
> IsolatedStorageFileStream fileStream = new IsolatedStorageFileStream("DeviceID.txt", FileMode.Open, FileAccess.Read, appStorage);
> using (StreamReader reader = new StreamReader(fileStream))
> {
> deviceUUID = reader.ReadLine();
> }
> }
> catch (Exception /*ex*/)
> {
> deviceUUID = Guid.NewGuid().ToString();
> }
> Debug.WriteLine("Updating IsolatedStorage for APP:DeviceID :: " + deviceUUID);
> IsolatedStorageFileStream file = new IsolatedStorageFileStream("DeviceID.txt", FileMode.Create, FileAccess.Write, appStorage);
> using (StreamWriter writeFile = new StreamWriter(file))
> {
> writeFile.WriteLine(deviceUUID);
> writeFile.Close();
> }
> }
> {code}
> The writing code should be moved into the catch after creating a new one as:
> {code}
> catch (Exception /*ex*/)
> {
> deviceUUID = Guid.NewGuid().ToString();
> IsolatedStorageFileStream file = new IsolatedStorageFileStream("DeviceID.txt", FileMode.Create, FileAccess.Write, appStorage);
> using (StreamWriter writeFile = new StreamWriter(file))
> {
> writeFile.WriteLine(deviceUUID);
> writeFile.Close();
> }
> }
> {code}
