Android - IllegalStateException:无法执行由InvocationTargetException引起的活动的方法。
提问于 2014-02-10 07:17:16
我正在选修Coursera课程，并试图完成我刚开始的一个应用程序。我试着让动画在一定的时间间隔内发生。See here for more details
我看了很多相同标题的帖子，但每个人似乎都有不同的解决方案。在Eclipse中保存和编译时不会出现错误。
这是我的日志结果：

对于第二个错误，参考资料$NotFoundException:资源ID #0x7f090000类型#0x12无效，清理项目并查看是否再次生成R.java，如果没有，请查看项目文件夹并查看是否存在所有文件
