Error in R.java

There is an error in R.java in this code on the second line

 public static final class id {
    public static final int 2ndQ=0x7f05000a;
    public static final int FirstQuestion=0x7f050000;
    public static final int MainTitle=0x7f050003;
    public static final int SecondQuestion=0x7f050008;
    public static final int btnstrt=0x7f050007;
    public static final int editText1=0x7f050001;
    public static final int imageView1=0x7f050006;
    public static final int maindescrip=0x7f050004;
    public static final int radio0=0x7f05000b;
    public static final int radio1=0x7f05000c;
    public static final int radio2=0x7f05000d;
    public static final int radioGroup1=0x7f050009;
    public static final int toq1=0x7f050005;
    public static final int toq2=0x7f050002;
    public static final int toq3=0x7f05000e;

It gives me this error

Syntax error on token "2", delete this token

I try to delete that line as it is the ID for a TextView I no longer have. Infact, I changed the ID of the TextView to "SecondQuestion" from "2ndQ".

How do I get rid of the error? It's preventing me from testing my app.

EDIT: Just to clarify this, the id is not present in my project AT ALL.

After 5 hours, I finally Got to the bottom of this hell! I had this error too, but none of the above mentioned methods helped, apparently i have renamed by mistake an id in a file that belongs to android internal, and not only that - i renamed to sth illegal (@+id/@+id/checkbox_spinner) Using notepad++ search i located the file in c:\Users\.android\build-cache... I erased the build-cache folder, the next start of AS was naturally slower as it created all the necessary files, and WOALLA! problem fixed!

I had this exact problem too. Where there was an error in my R.id saying to delete the token, but I was unable to remove it as it was no longer defined anywhere in my xml. So I had a 

public static final int 2ndQ=0x7f05000a;

in my R.java that I couldn't get rid even if I cleaned my project.

To get rid of it I had to

  • Recreate a TextView with this bad id of '2ndQ'
  • Clean the project and update R.java
  • Then delete the sacrificial TextView I had just created

Voilà, Your R.java should be fixed.

Make sure the elements in your xml files are not empty. The R file doesn't like it when there's an un-use or empty element with no values. For example:

Line 1: Average Height

Line 2:

The R file doesn't like it when line 2 has empty values.

I had a very similar error message starting off with Android development. In my case it was a simple naming error on one of the res strings - I had android:id="@+id/edit/message". The second / should have been an underscore.

The only error message was in R.java so when starting out with development was very confusing.

Sounds like the R.java file has not updated, try some of these general pointers to begin with:

  • Do not manually edit any of the files in the gen folder, as these are automatically built for you.
  • If you find it is out of sync then try refreshing the project.
  • If that did not work try a clean (project -> clean)
  • If that did not work delete the gen folder, from within Eclipse, (do not panic) it will then be rebuilt by Eclipse - however if there is a coding error of some sort it may not do this straight away.

Clean and build your application and try to run your application again..Don't do anything in R.java its automatically generated.Goto Project and clean it,build it.And try to run again.
