Removable Storage File Opened by FileOpenPicker Crashed App in Launch

Question

I opened a video file in a removable storage (USB3) by FileOpenPicker fine. Then I switched to another app and disconnected the removable storage. When I tried to run my app again the app crashed in starting. So I plugged the removable storage again everything was fine. 

What code of exception processing can prevent this type of error by using removable storage with FileOpnePicker?

Answer 1

Hi Charlie,

I would suggest you go through with this guideline: App suspend and resume.

I believe the reason of the crash is your video cannot find the source which is in your removable storage. I would say you can save the video information before the app is about to suspend and clear the video source, when the app is about to resume, try to open the video again with the saved state.

Answer 2

my video source path was stored in a database. I do not know when the removable storage was removed. I need to catch the exception of open file failed and may ignore this file.

Answer 3

MediaFailed event for MediaElement control?
