With GridLayout layout, unable to resolve Target & #39;android-7& #39 when it is deleted for some reason and the folder structure is organized;

The problem arises [2013-01-11 10:52:39-GRIDLAYOUT_V7] Unable to resolve target ' android-7 ' cause: At one time to do nine Gongge. The GridLayout layout was mistakenly used. So Eclipse took the initiative to download for me?? Gridlayout_v7_2 file and put it in the workspace folder.

Because it is no longer necessary, but also for the clarity of the folder structure, you need to delete it. But when you close this file, Eclipse self-compiles the project with an error, prompting? Unable to resolve target ' android-7 '. FIX: Here is said not to find Android-7 this API version number (not said Android version number). Then you need to find where to load this version number, for the version number file is usually present in the project? Project.Properties. GridLayout's row is removed (because it is not available.) Suppose you have to keep it, or change the correct version number.)
