App Acts Differently When Started From Device

Nathan Sokalski 4,111

I have an a that works perfect when started using the Visual Studio 2022 Debugger (I am debugging using a Surface Duo). As we know, running the debugger installs the app on the device. However, if I open the app from the device (not for debugging, just to test it out), it acts differently. My code does not include any #if DEBUG lines, so I cannot seem to figure out why it is acting differently. I cannot use the debugger to figure this out, because like I said, it works fine when starting it from the debugger. How can I determine what is different?

Did you run the program generated by the debug mode directly?

If so, the cause of the problem may be that the resource files and programs are not consolidated.

If you want to run the program directly, please release the application to your PC at first.

I'm not sure what that means. Does that mean I need to select Release instead of Debug in the dropdown in Visual Studio? Can you give me more specific steps as to what I should do?

Yes, you need to select Release instead of Debug in the dropdown in Visual Studio.

Causes that may cause program behaviour to be different.

The working directory of the debug run is the directory of the project file with the suffix csproj, and the working directory of the direct execution exe is the current directory, so the direct debugging will search for the local files needed in the build directory, and the direct run exe file will search in the Debug directory.

Could you please post the specific different program behaviour here?

It would be helpful for us to find the real reason.

Here are screenshots from the app when started from the debugger & device. The first is when launched from the debugger, and the second is when launched from the device while not attached to the debugger (or usb or other connection):

I will also note that the layouts displayed are the layouts from layout-land (landscape). The default layout (layout) looks the same regardless of which place it was launched from. I will also note that the two only look different when the "Start Next Hand" button is displayed, which is displayed under certain conditions, which are adjusted using the numeric buttons above it (the numeric buttons should always be visible, but the "Start Next Hand" button may not be). Being launched from the device does not prevent the user from rotating the device between portrait/landscape for other layouts in the app or rotating back to portrait for this layout, it is only the following very specific scenario in which there is a problem:

App is launched from the device (I have tested it on a Surface Duo & Samsung Galaxy S10e, but only the Surface Duo had a problem)

App is on the screen in the screenshot

The "Start Next Hand" would be displayed

The device is in landscape

It should be a hardware issue, please turn to Surface Duo SDK to create a new Discussion.
