Just updated to tools 17 and got this in most projects: Implicit super constructor Object() is undefined for default constructor. Must define an explicit constructor
And The project was not built since its build path is incomplete. Cannot find the class file for java.lang.Object.Fix the build path then try building this project Fix Project Properties fixed some projects, but not all. What did help was: I brought up project Properties / Android, selected a different Android API version, clicked Apply, then changed the API version back to what it was and clicked Apply again. The improvements in these new tools are very welcome, but come on, does anyone ever test how well new tools can migrate existing projects? -- K 22 марта 2012 г. 16:12 пользователь Yasin YILDIRIM <yasinyildirim...@gmail.com> написал: > It worked!
