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.
In Android Studio, I sometimes have to rename some field, attribute or method name.
I know I must select its name, then hit Alt+Shift+R. Then I type in the new name, and hit Enter.
However, sometimes it works, and sometimes... it just does nothing at all. The new name is just discarded and replaced with the old ones.
Can someone explain me why and how to force this very basic feature to work ?
I suspect that you've missed the refactor preview window that shows up when AS finds some code that it doesn't know if it should be refactored or not. For example, if the method being modified is referenced in comments, then AS will ask if you want to refactor those comment as well.
using a shortcut for "Rename" Variable Shift + F6
or
Select Variable/Method name -> Right Click in java file -> Refactor -> Rename
This also happens when using dagger and trying to refactor via Shift+f6. Android Studio hesitates when renaming things in generated code (which seems silly). Anyway, doing a project clean and then doing the rename works.
Alt+Shift+R replace a selected String (in your case the selected field, attribute...) and doesn't rename the variable, field... itself.
The feature I use for that task is Rename (not Replace). To achieve that you can either use Shift+F6 or right mouse click > Refactor > Rename. Now it changes the name also in other classes (if necessary).
For me, every time I refactor>rename it was showing me the usages and I changed them manually, but the name of the java class stayed the same, even I changed all the usages.
Finally, I unticked all the boxes, and it worked.
After today's work on my Android app, this started happening:
1: Android Studio say that the ID: welldana_image isn't there, even though it's right above: (Image below)
^ This problem persists all the way through this .xml file (activity_calculate_mine.xml)
2: The two project "show package" types aren't matching. In the first picture (Android style), the layout file activity_calculate_mine.xml isn't there, but in the second (Package style) picture, it is. (Pictures below)
EDIT: Everything works fine. I just don't want to push this to the marketplace, and suddenly it won't work. But everything works fine at the moment, though seeing these errors.
EDIT 2: Now this has happened? Is there an error in my manifest that I can't spot?
EDIT 3: Luckily I saved myself a copy of the project before everything went nuts. Apparently I deleted the activity_calculate_mine.xml. I solved this problem by simply placing the old version in the same directory as of before, and then just copy pasting the activity_calculate_mine.xml back into it's original placement.
Problem solved. Thank you.
Remove the "+" sign in the line android:layout_below="#+id..."
The #+id defines an id value, the #id referes to one.
Change this:
android:layout_below="#+id/welldana_image"
To this:
android:layout_below="#id/welldana_image"
How do I fix this? I already tried removing the R.java and cleaning the project via eclipse, but it doesn't help.
FYI I am trying to get PhotoStream from here: http://code.google.com/p/apps-for-android/, but so far it has been very difficult to get things work.
Okay..... 5 mins later google tells me the correct answer...
http://www.fairtec.at/en/it-blog-mainmenu-16/168-the-type-r-is-already-defined
I just didnt search hard enough.
"The type R is already defined"
That's the message you get in Eclipse if you try to build the Funambol Android Sync Client.
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.
Then the application even works fine in the Emulator.
Delete the R.java from the src folder and rebuild the project. This file will be automatically rebuit during this process.
http://www.fairtec.at/en/it-blog-mainmenu-16/168-the-type-r-is-already-defined
click right to project click properties
Project->Properties->Builders.
unckeck java Builder
delete file R.java
You may want to change your package names. It looks like you are using a 'PhotoStream'.jar which has it's R.class defined at the same package structure as you.
Here is a link to the R.java from the project on Google Code. Notice you are using the same package:
http://code.google.com/p/apps-for-android/source/browse/trunk/Photostream/src/com/google/android/photostream/R.java?r=83
I had the same issue when I imported a project from work. Turning off the Java builder as suggested in the article you found fixed my problem, but when I made code updates they were not reflected in the running app. In my case there was an R.java in my source which I deleted and that fixed my problem.
In my case,
as i m not using any IDE for programming but using command line Android..
i had two xml files, one in layout and other in layout-land. i was using same id "XXX" for both but while declaring i made small mistake
android:id="#+id/XXX" (in layout xml)
android:id="#+id/XXX " (in layout-land xml)
please observe extra space in second id declaration, so while creating R.java they were different and in R.java i had
public static final int XXX=0x7f040046;
public static final int XXX =0x7f040045;
which are same, so please be aware of extra spaces. Thank you
I'm working through a book samples programs and i get the same problem whether I create and type the code or whether i download the code already typed, so i'm thinking it's a setup problem.
I get this error in each each class:
setContentView(R.layout.menu) where the "R" is underlined in red and the code won't compile. If i add import android.r like "QuickFix" suggests, the red line goes away from the "R", but then the red line appears under "menu" (in this example). The same behavior occurs in each of the 5 classes that make up the project.
I do have matching layouts for "menu" etc. And (to the best of my knowledge) I registered them as Application Nodes in the manifest file.
It's driving me nuts. Thanks for any suggestions.
You are not supposed to import android.R as it won't resolve your resources. Just remove that import and try to compile again.
If you are working off a tutorial then also check to have the same resources as in the tutorial and also if you decide to name thing different then keep that in mind an reference them by your names.
The R class is generated by Android and contains IDs for all resources in your res folder. Go to your AndroidManifest and locate the package= attribute on manifest. R is in this namespace. So if the namespace is com.yourpackage.blah, you'll want to import com.yourpackage.blah.R;
The problem was that for some reason Eclipse was not autogenerating the gen/R.java file. I don't know why. One time it did generate the file, and a after Project..Clean and Build All everything resolved. Thanks for the input.
Also make sure your file names under res, eg drawables, are OK. I had a file name with capital letter and that prevented the creation of R with the same reference errors that you got. I did not check the error messages and it took me a good 10-20 mns to find this out.
Sometimes this happens to me.
It usually happens that I have been working with some xml element, and before clicking to a java document to hit "run" i just hit "run" while on the xml. I don't really know what happens when you "run" an xml, but it makes this horible file called some_xml_name.out.xml.
DELETE THIS FILE!
This file is the reason why you get so many R related errors, since the Resources library is never really created, or something like that.
That is my advice, without actually seeing the error you're getting in the console.
