Okay so here's the jiff of it, I was changing the android API in the Android Manifest and the Android Manifest from the "bin" folder. I changed the API from 10 to 12 manually by removing the 0 and adding a 2. Now, when I go to save the project its giving me this error found in the image:
This is incredibly and extremely annoying not being able to find the problem. Yes, I am aware that there are other questions with this matter but I can't find anything that is useful/fixing my problem so I'm asking for help here. If anyone could help me fix my problem that would be beyond awesome! Also, if needed I can put some code. Something to take note is that there aren't any errors coming up in the LogCat but just this annoying pop-up.

I've recently been attempting to set up SceneBuilder but suddenly my copy of Eclipse crashes pretty much instantly when I attempt to try and associate any external editor with a file type (not just XFXML). I've done some research and this seems to be the only page I can find talking about the issue, but I'm not sure how to take the advice therein.
I've linked the error log generated by these crashes. If anyone has experience something similar or has any idea how to go about troubleshooting this issue I'd greatly appreciate your input!
//I've included this code block to allow the pastebin link to work. There have
not been any issues with programming as the IDE won't operate as expected.
This question already has answers here:
R cannot be resolved - Android error
(108 answers)
Closed 6 years ago.
This has happened on a few different occasions, and I've always just kind of ignored it - but now I'm getting close to being finished with some of my projects, so it can no longer be ignored..
The Issue is as follows: While working on a project in Android Studio, on multiple occasions, seemingly at random, references to "R" will become Red, as if it were an error (or not found)..
For example, in my Main Activity, this reference to R is red, indicating an Error.
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
Everything with Android Studio is updated via the standard update channel.. The project isn't complicated whatsoever, and I haven't messed with anything that could be delicate, or somehow affect R.. so I'm left extremely confused..
Can anybody offer any kind of explanation regarding this issue?
I would greatly appreciate any advice I can get :) Thanks!
UPDATE: ALTHOUGH THE "DUPLICATE" I WAS LINKED TO BELOW (WHICH I READ FOR ABOUT AN HOUR) DID IN FACT CONTAIN SOME GOOD INFORMATION, IT WAS HOWEVER, A CONVERSATION THAT SEEMED TO CIRCULATE AROUND ECLIPSE (RATHER THAN ANDROID STUDIO, WHICH COULD DRASTICALLY CHANGE THINGS IN SOME CASES). THAT SAID, I DID FINALLY SUCCESSFULLY FIX THE CAUSE OF THE ISSUE! THIS PARTICULAR CASE WASN'T DIRECTLY REFERENCED IN THE LINK I WAS GIVEN, ALTHOUGH I DID GATHER ENOUGH FROM IT TO KNOW GENERALLY WHERE TO SNOOP AROUND FOR THE ERROR. SURE ENOUGH, IT WAS ACTUALLY A MANIFEST FILE REFERENCE TO THE APP ICON (LOL) SOMEHOW IT WAS MESSING THINGS UP, AND SO IN THE
<APPLICATION> SECTION OF THE MANIFEST FILE, I SIMPLY HAD TO ADD:
tools:replace="android:icon"
AFTER THAT, I WENT TO THE MENU AND DID A REBUILD, AND FINALLY IT BUILT THE PROJECT SUCCESSFULLY WITHOUT ANY ERRORS! HOPEFULLY THIS HELPS SOMEBODY ELSE OUT THERE WITH THE SAME ISSUE!
..FOR THOSE OF YOU WHO WANT THE SHORT VERSION OF WHAT I READ IN THE LINK: IN GENERAL, THE "R" NOT FOUND ISSUE SEEMS TO BE CAUSED MOSTLY BY ERRORS OR MISTAKES WITHIN ONE OF YOUR XML RESOURCE FILES WHICH CAUSES R TO NOT BUILD PROPERLY. THANKS FOR THE LINK.
The R file is a generated file, so you need to build the program in order to get the references to it. Make sure you check this answer to see how to rebuild it :
Android studio is based on Intellij Idea. In Intellij Idea you have to do the following from the GUI menu.
Build -> Rebuild Project
So I downloaded net beans C and C++ pack, and when I first opened it, it showed this warning message:
It works, but I want to fix this problem because it might do some problems in bigger programs I will create.
I have also tried to go to the link that was in the warning message that I posted here, but I really did not understand anything in there so it didn't help at all.
So if anyone knows what the problem is, and how to fix it, please tell me.
I am working on my N64 emulator for android, I have been thrown a ton of errors, So I find out that the error is originating from my app manifest. So I go to edit it and I get thrown this error:
Plug-in com.android.ide.eclipse.adt was unable to load class com.android.ide.eclipse.adt.internal.editors.manifest.ManifestEditor.
Has anybody else gotten this, Also I have gotten alot of other errors of the same manor like the hyper link finder and stuff like that.
Thanks
I fixed my own problem, If any of you are experiencing this problem, Just try restarting eclipse. I don't know how I fixed it but it just is.
I am new to Android Development/Java Programming/Eclipse so please bear with me. I've been going through the Android Developer Training (developer.android.com/training) and the Hello Android book by Ed Burnette and keep running into a problem that is making it difficult to move forward. I'll do my best to describe it and am hoping that the community can help me resolve it.
I began seeing this issue with the Android Developer Training (around Adding the Action Bar -> Adding Action Buttons) and it became impossible to circumvent at Hello Android's 3.3 Creating Opening Screen when I tried adding the Sudoku buttons. The only change I made when going through Hello Android was adding the Android Development Toolkit (ADT) for Eclipse. I don't recall this being a required download going through the Android Developer Training page so I am wondering if its addition could have contributed to the problem.
The issue that I keep running into is that when I go to build the project, Eclipse keeps telling me:
action_settings cannot be resolved or is not a field
activity_sudoku cannot be resolved or is not a field
container cannot be resolved or is not a field
fragment_sudoku cannot be resolved or is not a field
sudoku cannot be resolved or is not a field
I've tried several fixes that I saw on in the forum including deleting the import.android.R from the sudoku.java file in my src folder but that brings up a bunch of errors that say R cannot be resolved into a variable. I've tried cleaning and rebuilding and restarting Eclipse, methods that occasionally worked before Hello Android and the plugin, but keep getting the same errors. I've also tried setting to Android 3.0 and higher thinking that might be an issue but there was no change. Occasionally I get another error regarding not being able to find the path for a container but I've been playing around with the IDE for 15 minutes and can't seem to get it to pop up again.
I could really use some help on this.
Hope to hear from you,

This solution may, first and foremost, demonastrate how green I am with Android programming but I believe I found the solution.
Initially following the Android Developer Tutorial, I downloaded the latest versions - 18, 19, 20, etc. When I was creating the project, however, I was specifying much early versions for compatibility; all the way down to 7 or 8. I looked into this because I remembered seeing a message from the IDE regarding the Action Bar and how some commands weren't supported on Version X.
I went back and downloaded all the versions down to 7 or 8 and set the compatibility accordingly. The example now works with minimal other changes. I realize that I may be overlooking something but this is the only major change I made and it seems to have done the trick.
Hopefully this will help other newbies!
