Android 代码中无意删除了 .setting文件夹,重建后提示
gen already exists but is not a source folder. Convert to a source folder or rename it.
查了半天,总算有个明白人
- Right click on the project and go to "Properties"
- Select "Java Build Path" on the left
- Open "Source" tab
- Click "Add Folder..."
- Check "gen" folder and click Ok and Ok again
- Again right click on the project and in the "Andriod Tools" click on "Fix Project Properties"
