My project shows error in r.java.It was working fine before,all of sudden it says R.java is not found.When I tried to delete gen,gen file is generated automatically in which R.java showed error,
I tried cleaning my project,build path,deleted debug.keystore.But,of no use.
Could anyone help in resolving this issue.I am able to build new project,its all fine.The problem is only with one project
I have somehow managed to fix it, but I don't know exactly what did it. Here are things I did.
Deleted eclipse directory and reinstalled it and ADT.
Deleted my original project that was the first to have the problem.'
Created a new project with my original's project name.
Manually copied all my class and res files into the new project and
refreshed it.
Pasted the text of the old manifest into the new manifest.
I did all this, because simply importing the original project again didn't solve anything.
After the above changes Your Project will be Fine.
I have faced same problem. simply i delete my r.java file and restart eclipse then this problem is solved.

Try going to Project>Clean and selecting your project. This should generate the R.java file.
Or else you can right click on your project>Android Tools>Fix Project Properties.
Been searching for quite a while and have yet to stumble across a solution on this site or others. For some reason (even after a fresh install of the eclipse/ADK tools) the r.java file is not generating. Even when a new project is created there is no r.java. Tried the typical clean/build solution. Any guesses?
You can try to clean the project. Its a problem of the IDE. Try cleaning and building.
If you are using eclipse,
check project.properties file exists or not. If not, you can copy it from some other project. It is also possible that some hidden files are getting missed while copying project, which cant be created again by eclipse
Check Android jar file exists or not in project.
My PC went to sleep while battery was low. But when it recovered I found R.java file missing from my gen folder. My entire application is under crash.
The error is shown below:
If you recently added a new resource file and happen to use upper case letters in the file name, change the file name to lowercases and rebuild your project. That is what happened to my project.
The R.java file should be regenerated every time you do a rebuild of your project.
Clean the project,
Go through your code and remove all references to android.R.*
So when your R.java is corrupt or missing Eclipse tries to be helpful and thinks that the references in your code for R.something are missing the import file and inserts the android.R.* to your import list.
If you are using IntelliJ it has a rebuild R.java command.
If it is still missing then it means that something in your code is preventing it from being built. Pay attention to resource file names etc. Usually you can sport these naming problems in console view of eclipse
There are possible chances, you have a problem in your layout xml or in your code.
Try looking at file that you had open in your eclipse when it went to sleep, and code snippet that you were working at.
Edit:
R (resource file) regenrates at every rebuild of your project. For some error in your project your project wasn't able to build that why your R file is missing. All that you need to do is to fix issue in your files, code and xml files.
I got the same issue. Nearly I spent whole day working on it to figure out the reason and tried all the 100 solutions provided in the blogs. But nothing helped!!! After setting up a new workspace I figured out. Remove unnecessary libraries in your project. You can check this by Project-> right click-> properties-> Android-> and remove unnecessary added libraries. It worked :) Hope it helps some one.
I have tried to clean it, reinstall it.
But, Everything went in vain, R.java file is not creating
I am working with the same configuration on another computer its working pretty well so i don't know where the problem lies.
BuildConfig.java doesn't diappears and R.java doesn't appears...
try to delete BuildConfig.java and R.java and re build
I have just opened Eclipse as I need to make some changes in an existing project. I added a new file to my 'Raw' folder and refreshed the folder and when I went to build it shows a error 'x' on the project but not against any of the source files, etc. It also shows an error against every other project in Eclipse even though I haven't touched any of them
If anyone has come accross this problem before please let me know how I can rectify it.
I have several times problems with Eclipse highlighting everything with errors even when everything is fine.
Sometimes it looks like Eclipse caches the errors and does not clear them properly.
In those cases, I tried different things such as:
removed the file you just added. Refresh and clean the project and see if it has fixed it.
Remove project from Eclipse and import it again.
Close Eclipse and open it again.
For me, the above sometimes work.
The issue might with unresolved build resources. like some previously used path might not be available now. You can goto the properties of the project and check in the respective tabs if some of the paths earlier set are not valid anymore.
I've managed to resolve the problem. You need to delete the debug.keynote file in .android which had expired! Then clean and rebuild your app and the debug.keynote file will be recreated and the error removed.
