I had placed a text view on my page and i didn't realize I had misspelled the id it was meant to be txtTick but instead I had hit the / and it was txt/tick. I corrected this error however it had saved to my R.java file and i keep getting the error.
Syntax error on token "/" ,, expected.
However I cant modify this file and I don't want to touch it encase something else happens. I have checked my strings.xml and that string doesn't exist anymore.
I am unable to clean my project because of this error and have tried restarting it as well but have no idea how I can fix this.
Any ideas?
R.Java
public static final int txt/tick=0x7f050089;
xml
android:id="#+id/txtTick"
delete your 'gen' folder rebuild your project another then
simply delete your workspace .metadata file and import your project again and rebuild it
delete R file and then Clean build your project this might work for you..
Delete R.java, modify strings.xml to include the string that doesn't existed. Rebuild the project and run.
Check R.java commentary:
/* AUTO-GENERATED FILE. DO NOT MODIFY.
*
* This class was automatically generated by the
* aapt tool from the resource data it found. It
* should not be modified by hand.
*/
as Varun said, clean and build your project to generate a new R.java file

When I was naming one of my activities in Android Studio, I accidentally clicked the "\" key and I've deleted that activity but now when I run the project it says I have an error in my .R java file..
I tried to delete the error which will fix my problem, but whenever I delete the line of code it just regenerates it when I run it again...
I've already tried; deleting the line, cleaning my project, and rebuilding my project. None have worked.
The line of code I need to delete is:
public static final int title_activity_song_one_hundred_nine\=0x7f0c0054;
How do I go about deleting this line of code for good? Thanks.
You need to clean your project by
Build > Clean Project / Rebuild Project. this should re-compiles your R file in android studio.
If still not work, you must have errors in your resource files. Check your xml files such as layout, string, etc.
Try this...
Close your app in an Android Studio/Eclipse.Go to your workspace where you have the project.Open that R.jave file in notepad and remove the "/" symbol then save it.
Now open it in Android Studio/Eclipse IDE. Your error may fix.
I'm working on my project in eclipse , but after adding some files I clean my project, but after clean the R.java file automatically vanish from my project & lots of error on my project.
again I tried to clean my & build it but my R.java files can't back.
What I'll do at this moment?
if R.java is not being automatically created then there is an error somewhere in your xml. Triple check everything.
Check your XML resources (especially these recently edited) for mistakes and sytax errors. When you have an error inside one of these files, the R class autogeneration will abort.
surely you have error in XML.
edit:
Other possible causes: Upper Case Characters in your resource file names; Invalid Characters in your resource file names (you can use only a...z, 0...9 (not as first character), . and _); File names starting with a number

My R.java gives an error
public static final int 1405308882_more = 0x7f020000
Don't know or understand why its giving this error, i regenerate the R.java file and it still gives me the following above. and when i hover my mouse over it, it says
underscore have to be located within digits
I tried editing it but when it compiles it still regenerate the same name variable.
Please before anyone starts rating this question as usless take your time to understand it
I don't have error in any of my java files either in the src folder or layout folder every thing else is fine its just the R.java that generates that constant so please understand before you jump to conclusions. Thank you.
There might be some thing error in your res folder once check each and every file and clean your project once and refresh it again..
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.
Hope this helps..
It wasn't the XML file that was the issue. It was an image in the resource folder with a name that didn't follow the standard naming rules and thus made the R.java to generate that error.
The reason it regenerates same is because it regenerates from your code you should check the .xml files of this project the problem is probably at 1 of them try clearing xmls you have created then regenerate it.
I was doing some work on my app when I accidentally deleted the file R.java in the gen folder. Is there any way to get it back? I need it because it is giving ever activity errors. I tried copying my data into another application and that didn't work. I also checked my recycle bin and there was no file and cleaned. Please help?
Several ways to get out:
Simply modify(add a white space or so) in one of your resource files and save it, if the eclipse is enabled 'build automatically', the R.java will be re-generated again.
Go to project - clean project, clean your project and it will be re-generated when you run the project again
It is automatically generated file
Just clean and rebuild you project If there is no error{there must not any xml error which neither shown error nor let R.java build} then it will create your R.java file
again
Every Successful build just re-create new R.java file
R.java is auto generated when you delete it, make sure the xml file has no error . If this is also not solving your problem the start doing your project from scratch no copy paste.
on cleaning a project to update a image My R.java file in gen folder got deleted with no clue how , as a result giving errors how to recover it
Delete gen and bin folder. And perform build.
If R.java file is not generated, probably you have some errors with resources.
Check your Android manifest file. I bet you have a typo there. If manifest is clear, R.java will be automatically re-genrated.
Also remove all reference to the R.java file in your source that u might have imported mistakenly.
Check your resource files. Remember that your file names must contain only [a-z0-9_.] No "-".
The best way to know where the problem is coming from is to check the "problems" view in eclipse.
