i am trying to insert new activity in my android application,after inserting the new activity it gives error in the R.java file,
String class
public static final int =0x7f050009;
it erase the variable name,and don't allow to update variable name. Is this problem occurs because i inserted new activity in the application,or problem is other ?
R.java is generated by android automatically. You don't(shouldn't) write/modify it. Just delete it and then clean and build the project again.
Try to clean you project from Project>Clean.. and build again.
When you create a new activity and after adding it in android manifest xml file, then building an application in eclipse should re generates the R.java.
If 'Build Automatically' enabled in eclipse, then on saving manifest file itself will trigger re generating R.java. Don't do anything in R.java its automatically generated.
if u create the different packages for your project Like Activity, Fragment,Bean.
In such case R will show in red color at setContentView method.at that time keep cursor at R and press ALT + ENTER it will show for import R.
click on it..
it will resolve your problem.

I was searching about R class in my project to get look on it without editing it.
When I press ctrl and click on R Android studio opens the resourse file instead of R class
Where does it exist in my project structure?
This is not about understanding R class in Android, It is about finding it the project for just having look inside it.
You can find R class by searching it with "shift + cmd + o" or "double shift".
I guess new android studio update directs to the xml source of the resource.
Please check in this path "app\build\intermediates\incremental-verifier\debug\your.package"
How do I solve this error in my R.java file. I have cleaned the project and set the resources to UTF-8.
public static final int editText-contact=0x7f050073;
it underlines the "dash"(hi-fen) in red. I have tried to edit it but the logcat stated:
[2014-05-28 15:46:42 - MIPS_HC] R.java was modified manually! Reverting to generated version!
what other ways that i could remove the error??
I got this error when i changed my #+id/RelativeLayout1 to #+id/addnewadmin. I also changed the ids for my individual components like #+id/textview01 to #+id/textview01_firstN.
Is that a wrong move to do because I am still a beginner in android programming. Please help. Thanks.
Read Java naming conventions again. You don't use a hyphen in names.
Simply Replace:
editText-contact
with:
editText_contact
I am getting the following constantly generating in the R.java file:
public static final class id {
public static final int =0x7f0500ae;
I have done research and it all pointing to the strings file. I have checked my strings file and there is no errors. The application is not producing errors anywhere else, its just this single line that is being generated.
Can someone please help.
I had the same issue and found it odd that my strings.xml file didn't show any errors, but was able to resolve by searching through the strings.xml file for empty string name values.
Found:
<string name="">Username</string>
Changed to:
<string name="lblUsername">Username</string>
Worked and was able to compile, hope this helps.
One or more xml files might have compilation problem. Can you check?
If you are using eclipse, sometimes the xml file or folder wont show it has error (red * icon in the file or folder.
If this is not the case then delete the R.java file and rebuild the project.
or
Clean your project and rebuild it again.
This morning when I opened up Eclipse to work on an Android project I got an error inside the R.java file.
I know what the error is, but I can't seem to grasp how to fix it ;\
The code where the error is:
public static final class string {
public static final int =0x7f040010;
public static final int app_name=0x7f040000;
As you can see, the first field doesn't have a name and that gives an error of course.
Problem is when I delete the file and it's auto generated again, the error is still there.
If I try to manually change or delete the field it doesn't help. Still an error.
Tried to restart Eclipse - no difference. Tried to clean up the project and I've tried to "fix project properties" from the Android tools menu.
Anyone? It's really annoying as I can't continue with my project. I might have to delete the project and copy the classes, xml and drawables, but I'd rather not - hate doing cumbersome work :S
The problem is most likely with the strings.xml file. When you build the project that file is compiled into the R.java resources class. So check your strings.xml file carefully and as there is most likely an issue there that is causing this compilation error.
Most probably, u have an empty string in your strings.xml
<string name=""></string>
I am getting error in R.java file.
The error is
"The type R is already Defined."
I have tried deleting the R.java and Cleaning the project.
step i have wrote if this situation raise ::
dont delete it, clean it.
goto Windows >>show view >>console and try to solve error?
goto Project >>click -> build automatically
remove import of R from import section
goto layout file and check that is there any id is same name ?if yes then change it
in layout file delete any single space,save and refresh and run.
Reason is that you have checked two Builders that try to generate the same class.
You just have to uncheck the Java-Builder from Project->Properties->Builders.
May be there are two builders for the project.check it in project->properties->builders. I too had the same problem.
Chk this out: Fairtec: Type R is already defined
