Application closes unexpectedly

Hi! I have an application wich never closes. I intercept the back button to minimize the app insted close it. The only way to close the app is closing it from window apps in Android.
I don’t know way sometimes the app was closed. When I back to the app, the slashscreen starts again.
I don’t have logs, so I don’t know where to find the problem.
Any idea?

This is because Android closes the process to freeup memory, you need to add the Backgroud plugin to make the app alive even if user goes to the menu or something like that.
