问题
When I try to run my app on my Samsung Note II, I get a ResourceNotFoundException for this line
setContentView(R.layout.activity_main);
However, I don't get this exception when I run it on the emulator or my Samsung Note 10.1.
Both are running Jellybean and my xml files are in folder called layout-land, and the XML file is in there. I tried cleaning my project and re-building, but it still doesn't work.
Does anyone have an idea what's wrong?
Let me know if I can provide any more information. Thanks!

回答1:
I suspect that you have your problematic layout files only in the layout-land directory (based on what you wrote in the question). This means that if the device is launched in portrait mode, Android will search for your layout in layout-port directory, then layout, but not layout-land. I might be wrong but my hunch is that your Samsung Note II starts in portrait mode and thus doesn't see the layout file.
You have to provide a fallback layout resource. Either copy the layout from layout-land to layout-port and modify it accordingly for portrait mode or just copy it to layout directory as a fallback layout.

AFAIK, Samsung Galaxy Note II 's default orientation is not in landscape
try putting a set of resource files in /res/layout for those devices which are not fit the specific layout characteristics
回答3:
The xml files are in layout-land so they are only valid when the app/device is in landscape mode. Try moving/copying them to just layout and you should be fine. You may want to put a generic layout in the layout directory and a landscape optimized layout in layout-land (or look at other resource selection criteria).
