Hi Yogi Yang
wm22 or older?
first try to clean up temp files, used by WM as a kind of cache. Only then you will get a fresh recompile
c:\Users\YogiYang\AppData\Local\Temp\FRMK_Android_xxxxxx
and also the Android map inside your project map, i.e.
c:\My Mobile Projects\My_Project\Android\
Then do a recompile/rebuild
WM23 will do a better job by the way. No such problems since I use that version
