我以为这件事应该由操作系统来处理，但猜想不是.

I thought this thing should be handled by the OS, but guess it is not.

已编辑:我现在正在捕捉PACKAGE_REMOVED"意图，并检查EXTRA_REPLACING"以确保它不是重新安装，但我不知道实际使用的实际代码删除小部件.

EDITED: I am now catching the "PACKAGE_ REMOVED" intent, and checking the "EXTRA_REPLACING" to make sure it's not a reinstall, but I don't know the actual code to use to actually remove the widget.
