This issue was related to switching between portrait and landscape modes.
First, i trusted in Android auto-resize, and it resulted in an acore crash when people switched to landscape mode (for example, putting out the physical keyboard), although it didn't crash in the Android emulator (it did a weird resize though).
In this particular case, it was no point on supporting landscape mode (too small buttons = unplayable), so i decided to show an error advice when landscape mode was activated. And this wasn't as easy as expected.
First of all, i realised that i needed buttons references in both portrait and landscape layouts, why? Because the user could add the widget while being in landscape mode, and MineSweeper's data and buttons needed to be assigned to their PendingIntents, otherwise it'll result in an unexpected behaviour, and user would see how widget didn't response when switching to portrait! So i left the buttons part of the layout in the "error layout" setting visibility to "gone".
Then, next problem appeared. Each time the layout changes from portrait to landscape, the view is re-inflated, so you need to re-assign PendingIntents to all layout elements before each updateAppWidget call (and reassign all viewResources too!).
And that's it!
And remember, don't trust Android Emulator and test your app in all devices as posible.
I suppose there are better ways to solve this issue, you can share them with us in the comments!
