I have tried to compile my project and then this error suddenly occurred. What could be the cause of this? can anyone please help me? error occurred in R.java file
This error occurs due to change in layout. May be you have to add a string in it.
e.g. android:layout_below="abc xyz ghi"
I just encountered this error, and it is definitely odd. I fixed it be renaming the ID's of several elements in my main activity layout. I had used hyphens in the names which resulted in this error. Changed them to underscores and all is well.
You can try to clean and rebuild you project. The R.java file should be recreated. And if this does not work you can try to find the missing ;.
I hope that solves the problem.
Just encountered the same error. Turns out that I have managed to enter ID value which included space into id field of a Button (and the IDE didn't protest). (Apparently I had clicked into bad field when trying to change text label.)

I was editing a layout in Android Studio and added a Switch.
I first set its ID to "switch". After a compilation error, I realized it was a reserved keyword and I cannot use it, so I decided to change its ID to "mySwitch" but Android Studio crashed at this moment.
After launching it again, I checked the ID, which does have been changed to "mySwitch", but when trying to compile, I still get this error:
/path/to/app/build/generated/source/r/debug/com/example/program/R.java: error: invalid symbol name 'com.example.program:id/switch'.
I guess Android Studio did not change all occurences of "switch" before crashing, but I did not find any.
What I tried but did not work :
Changing again the ID
Deleting and adding again the Switch
Clean Project
Is there any occurence of my Switch ID I did not think of ?
I found the problem, I should have thought of that earlier.
What I did is right click on "my_layout.xml" > Analyze > Inspect Code...
Then it showed me this line
app:layout_constraintEnd_toStartOf="#+id/switch"
I don't know how I missed that...
you need to find where in your xml code an object had taken "null" as an id android:id="#+id/null"
so first you need to go to the last xml you edited
1 - click right on it
2 - Analyse
3 - Inspect Code ...
4 - click ok and you will see how much errors and warnings you have
try manually deleting the build folder in your project and use "build" -> "Rebuild Project". By that way all mapping files (including your inconsistent layout mapping) should also go away. and Rebuilding recreates the map.
I still doubt, if you have missed to change id with name switch somewhere else. Think that way also..
same xlm file you declear samething like
`android:id="#+id/null`enter code here`
find it and fix;
from right click on eath xml file..and run analyze--->Inspect Code
You have to check your last edited xml file if it shows the error of invalid name symbol where id is assigned to null go through the code and check all the id's in my case the layout constraints were assigned null value. Check the id's and either remove them or assign them suitable values
Ensure that you have not named your resource a system reserved name like Continue.xml or such.
Here is my values\strings.xml (the default file) and everything is self explanatory:
My question(s):
How can it be "not found in default locale" if I am editing the default locale (values\strings.xml)?
How can it be a lint translation error if I set translatable="false"? In the values-pl\strings.xml (and values-ru, values-iw folders as well) the strings don't exist even? it shouldn't anyway.
I can't seem to understand why I don't get the error for the Russian string.
(I would show the values-ru\string.xml or values-pl\string.xml here but there is nothing there of interest, since the strings are missing anyway...)
this happened to me too
I do 2 things:
Verify entire file to see another translate not done ( I have ones in file en but in pt-br)
Clean, update gradle and quit and restart the Android Studio
Rebuilding can take a long time. YMMV, but...
Simply remove the offending line and re-add it.
Worked for me. Very fast.
In my case this helped me:
Select the strings that cause error.
Cut them.
Paste them again
If it doesn't work for you, try adding the same strings to strings.xml(v21) file.
Press Invalidate Caches / Restart ... to restart android studio. It worked for me. Actually this happened when I had copied files from my other computer and pasted via file explorer.
I solved this issue by following below steps:
cleaning my project
rebuilding it
and finally pressing invalid caches/ Restart in file menu
If you just Clean Project it probably works. It worked for me.
I had the same error message, just with the weird issue that it was thrown in the default locale itself and all translations. Turns out you should not use dots in your name (e.g. name="bla.blub") because it will be internally converted to "bla_blub" and then it cannot match with "bla.blub", hence the error.
I only had to change the dots to underlines in the default locale and then all other errors in other translations (including dots in the name) were gone as well.
But be aware that other build tools can still create issues, so replace all the dots with underlines instead!
Quitting Android Studio and restarting it fixed it for me.
You simply just have to copy the offending line (or just one of the multiple of offending lines), remove it, and re-paste it. That removed the issue for me.
Just make sure that you have same naming conventions on all strings files including the same capitalization.
let's say if you have "sign_in" in strings.xml and "sign_In" in your fr/string.xml, so it will give you error on fr/strings.xml like "is translated here but not found in default locale". So, when you edit to "sign_in". The error will remove.
I was having this problem for all the strings in my xml file.
The thing is, your default strings.xml shouldn't have a tools:locale attribute as the other translated files have. If it does, whenever I compile the app in release mode, it treats it as another translated file.
I've created a tool to manage the translation status of android apps.
It not only tells you what strings are missing on the other languages, but it can also report, and clean the left over strings that you may have deleted on your default translation file.
https://github.com/gubatron/android-missing-strings
To clean all left overs in other languages invoke like this
./ams --cleanleftovers -o all.txt
This will clean the left over strings and it will output the missing strings report for all the languages into the all.txt file
Copy and paste didn't work for me.
I also tried Clean and restart, the previous error was gone but new entered strings still have new errors occur.
I tried closing the opened strings.xml file and Translations Editor, then restart.
strings.xml file and Translations Editor
That works for me.
Well, in my case, this happened when there was a format error with the previous string of the string that's being reported. Unfortuantely that format error was not reported. Correcting the format error solves the issue.
Add this,It will work
<resources xmlns:tools="http://schemas.android.com/tools" tools:ignore="ExtraTranslation">
Press double shift for open Translations Error and then check and uncheck in Untranslatable column the item with error.
this is causing the error
public static final class id {
public static final int timeToSend=0x7f080021;
public static final int timeToSend,=0x7f080023;
}
whenever I remove the second and save the file eclipse changes it back. I tried changing it while eclipse is not running and yet when I opened eclipse it changed the file back. I don't have any duplicates in layout to cause the problem. I tried cleaning the project and it didn't work.
turns out I wrote android:layout_alignBottom="#+id/timeToSend," instead of android:layout_alignBottom="#+id/timeToSend" that's why it nade a duplicate with the comma. sorry for the trouble
Maybe it's because you have an XML element with the android:id="#+id/timeToSend," ?
Android ID's cannot have any special characters in them. So android:id="#+id/timeToSend, would be wrong due to the fact that it has a comma. All you have to do is find that ID and rename it.
It's not recommended to edit the R.java file because it generates itself based on all the ID's you have created. The only way to edit it is to get rid of the ID's that you have declared in XML, otherwise, every time you clean the project, they regenerate.
Something that I always try when R.java is giving me problems is rebuilding the project.
You should be able to find the option under Project and then Clean.
That's only if rebuilding it hasn't worked.
Good luck and I hope this helps!
I use IDEA's intellisense automatically (Alt+Enter) as I am so used to know which option it will offer. So this morning I was renaming some XML id (LinearLayout's id) and (probably) somehow generated an entry directly into R.java file. Later I wanted to compile the project, but I keep getting error: <identifier> expected. The R.java looks like this now
public static final class id {
public static final int #+id/linearLayoutMessages=0x7f080012;
//... other IDs
Obviously the torn in the file is the prefix #+id/.
I tried removing R.java and rebuilding the project, but it did not help. The same error and the same entry keeps regenerating itself. I can solve this (temporarily) by manually removing this entry from R.java, but I get this message each time I try to rebuild the project.
Any ideas why this strange entry remains persistent even after deleting R.java? The version of IDEA is 11.
You had "#+id/#+id/linearLayoutMessages" in your XML, you silly goose!
in my case it was that I wrote android:id="#+id/52_day_card_image" which is illegal. The solution was android:id="#+id/fiftytwo_day_card_image". Silly me, or silly compiler, your choice
I am getting error with the generated java file. But the code is fine and good . Can any one give suggestion.
thanks in advance.
Based on your image it appears that you are getting an error with the element with id of "enter", try changing the id of that element to something more descriptive and the error might go away.
You don't say which error you are getting. Usually you can resolve errors in R.java by removing it, and letting Eclipse regenerate it. If you still are getting the same error, you can try to rename the controls with the offending id.
If you wish further assistance, you need to say which error you are getting.
