Saving data to disk on Hololens

LOL_Vampire

Hi, I have been trying to output some data from my app to disk on HoloLens. I am trying to avoid using playerprefs. Based on what I understand, I should be able to write to ApplicationData.Current.LocalFolder [source: https://msdn.microsoft.com/en-us/library/windows/apps/windows.storage.applicationdata.localfolder.aspx].

I used the code in the example for testing and I got errors saying async is not available in C# 4. A quick google shows async and await is not supported by Unity yet. I wonder if there is a way to output data to disk on HoloLens? (Preferably not on cloud and not using playerprefs)

Any help is appreciated!

Hi HoloSheep,

Yes, I came across this page during my research but it didnt really give an API or an example about how to save files on HoloLens. Could u point me to the right direction?

Thanks

@LOL_Vampire there are a couple of links referenced in some of the connected pages of the docs to the file pickers and if you dig around for UWP file api you will find articles like this that may help get you started.

Note if you end up using any of the newer .NET apis that are not in Unity's flavor of mono you will want to surround your calls with the appropriate conditional #if such as

#if !UNITY_EDITOR 

Important to keep in mind the following:

HoloLens uses the app model provided by the Universal Windows Platform (UWP), a model and environment for modern Windows apps. The UWP app model defines how apps are installed, updated, versioned and removed safely and completely. It governs the application life cycle - how apps execute, sleep and terminate - and how they can preserve state. It also covers integration and interaction with the operating system,** files **and other apps.
