Hello, I can not put Eric's launcher by default,

Hello, I can not put Eric’s launcher by default, I can not get the window to use WatchClockSkin by default.
Could you please tell me how to handle it again, thank you.

When I press the kw88 button, it returns to the default launcher

I go to uninstaller, watchClockSkin, launch the application by main activity, the launcher launches but when I press the buttons, it comes back on the launcher of the watch.

Same problem ? https://plus.google.com/106226650002946398838/posts/76vGt1v119u
