title: R.java cannot be saved
body: <p>I has a android project and I write it in eclipse. It can run but somehow my eclipse cannot work so I make another project in eclipse too and copy the java, android manifest and the layout xml. I have changed everything so it would work.I got error at the R.Java which the error some of my variables are including space in it although I never make variable with space character. I corrected it by change the space with underscore but it changed back and there is still space character. I also tried in android studio and it still happened. What is wrong with it? Here is my R.java. The DT Count cannot be changed to DT_Count although my code in source is DT_Count and some how it changed to DT Count and cannot be changed.</p>
