Eclipse Crash and Not Regenerate R.java

Question

I know this question has been asked & answered before. But, none of those answers work for me. Eclipse crashed in the middle of a build and keeps erasing the R.java file. I have tried to clean and rebuild. Does not help. I was using SDK build tools 19.0 upgraded to 20.0. Does not help. I didn't touch anything in the XML files and I do not see any errors in the XML files.

Answer 1

尝试另一个IDE，例如Idea ，检查这是否是由于Eclipse故障而不是您最近更新的SDK引起的

Answer 2

I my case there was something wrong with my XML usually my layout files, when you have a problem in your XML files the clean option does not work properly, check your XML files ( layout and manifest ) and after that clean your project.

Hope this help you

Answer 3

I did get my R.java back. There was a jpeg for another project stuck in a drawable directory. Don't know how it got there. and, still lots of unexplained errors though.

Answer 4

All my other errors were from switch statements using R.something_menu.icon for cases handling user responses. I got a message that as of ADT 14, switch statements can no longer be used. I had to migrate to if...else It works. Don't know why. But, it solved the problem & saved my code.
