Windows 10 launched today and with it comes a new SDK for building “Universal Apps”. This new SDK comes with a lot of new functionality. One of those pieces is a new way to set the lockscreen of a device. This new API is available on the new UserProfilePersonalizationSettings class. Previously you only had the ability to set the lockscreen within phone apps using the SetImageUri method on the static LockScreen class. The method accepted a Uri that had to be local to the app.
Windows.Phone.System.UserProfile.LockScreen.SetImageUri(new Uri(localFileName));
The new UserProfilePersonalizationSettings class has a TrySetLockScreenImageAsync method that accepts any local StorageFile (I have not been able to set the lockscreen using the FileOpenPicker). This means you can save an image to the local or roaming folders, or use an existing image packaged with your app.
var file = await StorageFile.GetFileFromApplicationUriAsync(new Uri("ms-appx:///Assets/AwesomeLockscreen.jpg"));await Windows.System.UserProfile.UserProfilePersonalizationSettings.Current.TrySetLockScreenImageAsync(file);
This example uses a file packaged with the app in the Assets folder.
You should check if the device has the ability to change the lockscreen. I’m guessing this is in place for future Windows settings.
if (Windows.System.UserProfile.UserProfilePersonalizationSettings.IsSupported())
{ var file = await StorageFile.GetFileFromApplicationUriAsync(new Uri("ms-appx:///Assets/AwesomeLockscreen.jpg")); await UserProfilePersonalizationSettings.Current.TrySetLockScreenImageAsync(file);
}
Now go and create some amazing lockscreen apps for Windows 10
