Bug Fixed

Congratulation!
Finally get almost everything working in release mode. Saving new data,
sync chart and release building configuration r all working now.
There r still some trivial issues:
1. The chart is not synced in some special cases. But we can manually
reload it.
2. The error report pop-up window. Ignore it. SDK delivers release
package to device successfully. Checked in the file system

The real last update of today. Hopefully it's the last of this month as
well :)
