I am trying to build my Android project in Eclipse and this error is popping up in my console:
W/ResourceType( 265): Unknown XML block: header type 0 in node at 413
This is causing my R.java to not generate. I have absolutely no idea what this means. It's not even telling me which file is causing the error. This is quite a large project with many XML files and I've looked through every single one and they all seem to be okay. Can anyone shed some light on this?
Any help would be greatly appreciated.
R.java includes all Ids, layouts.. If there is any problem like formating error in id name or any other error of layout. then R.java file will not be generated & your java class file will show you error. so first check your xml file
There might be the possibility that you have put your xml file in the wrong folder under res dir. Like if you are trying to access <wallpaper> tag in Android xml file you must put it in res/xml directory otherwise it will show error.
You can try following options::
close other projects.
clean your project.
check in the source files(java classes), if there import android.R.* is present , remove that.
check in your res folder, if it is showing error in any folders like drawable, layout, values.
5.correct if you get errors.
R.java is not coming because it is not getting id of any/more resource/resources.
this will solve your problem. thanks
Your error may come from incorrect line ending. You should check this Link. Hope this help.

Here is my code: http://pastebin.com/CkD6485J
When I run it through I get an input == null! error and I marked all the places the error was caused by. I put the /res/ folder in the build path and it didnt work. I tried removing it, and putting it back in, and I tried removing the /res from the file location. I'm also following this from this tutorial: https://www.youtube.com/watch?v=WLhUzuTSTAc so I'm not sure why it won't work.
The resource /res/sheet.png should be in the same jar as the GameComponent.class` file. Also the path is case-sensitive. Open the jar with 7zip, WinZip or whatever and inspect the path.
It might be, that it should have been /sheet.png, when all below /res is added to the jar.
sorry about this but after a few days of of looking it over i figured out that there was something wrong with the .png file I used for my resource. I downloaded a completely new one and it works fine. Thanks for the ideas though
I edited a small amount of my xml code
(tried to add an android:src"#drawable/" but it didn't seem to like it so I deleted it after)
and my java code (added Troop1P1.setVisibility(View.VISIBLE); to the end of an OnClickListener,
and again deleted afterwards [I had already used findViewByID for Troop1P1]).
However, my whole code has now stopped working, with every "R" in (R.id.) being highlighted, with the text "Cannot resolve symbol "R"" when hovered over.
In addition, when I run the code I get the following error:
error: Error: No resource found that matches the given name (at 'layout_above' with value '#id/btnTroop1P2').
However, I've checked and I'm fairly sure I've correctly id'd btnTroop1P2 using android:id="#+id/btnTroop1P2", so I can't find any problems there.
I'd really appreciate any help, I just want to be able to run my project again!
are you using Eclipse? .if yes go to Project -> Clean... -> Tick your project name -> OK.
Give that a try. I always get similar problems and this solves it for me anyway.
When this occurs, it's usually because you have an error in your layout XML. When an error exists there, the R file is not generated. Therefore, Cannot resolve symbol "R" is the only information Java can give you. Go back into your drawable, layout, or any other XML you've been playing with and make sure you have everything properly formatted.
I have no clue what suddenly have happened. I restarted my Idea workspace and it popped up the following error:
Cannot convert project: C:\workspace_IntelliJ\Main\new-webapp.idea\workspace.xml: Error on line 1: Content is not allowed in prolog.
What does this error mean? I have checked my workspace.xml. Whenever I try to open it in an editor it displays the following (I believe it's broken):
nulnulnul
I have no clue what to change and how to fix this thing. Any help on this would be great!
Just remove workspace.xml file. It worked for me ;)
Ok, I fixed the problem (not sure yet why the file got broken though).
Step1: I created a new workspace and copied my source files and .idea files excluding workspace.xml. Infact I deleted it before copying it to new workspace.
It worked! guess deleting and re-creating was the option
It looks like this problem can be fixed by opening up the .idea/workspace.xml file in a text editor and saving it specifically with UTF-8 encoding. This is possible using Sublime Text for example. This fixed the problem for me.
I need to start an activity in my titanium module.Then I have to setContent of my Layout in my pure java code, But I cannot locate the layout file in Titanium module.
I used below code but i get error that file not found.
int id = TiRHelper.getApplicationResource("layout.activity_main");
If i put my layout files inside "platform/android/res" i get error,any idea to help me?
invalid resource directory name:
[ERROR] Error generating R.java from manifest
Regards
Might have nothing to do with it but I once ran across this problem and solved by putting the application id in the com.company.app format
If your XML's contain errors your generated file might not build try erasing most of their content and making sure id's and file names are not duplicated and no capitals and spaces are used. If it works you can start adding stuff.

You're importing invalid R class I Think,
import yourpackage.R class
for example
com.example.R
what actully happends that u import android.R class not yourpackages.R
I am having trouble with my R file, I was able to get it running again but then i seem to have another issue. Nothing seems to be generating after all the work I put into it. I think my problem is coming from the fact that my src cannot see the xml files and I don't know why. My find_bluetooth_devices is underlined in red squiggles and says it cannot be resolved or is not a field. However, I know for sure that I have created a xml file that included everything for it to work. I feel as though the xml file is not being seen by the src as it should be. Does anyone know what I can do in order for the src file to see my xml file?
setContentView(R.layout.find_bluetooth_devices);
Make sure your import statement is for the correct R file. You could have mistakenly imported android.R instead of your projects R file.
Here, read through this and the next one and see if you can solve the problem:
Also, make sure you dont have import android.R at the top.
Where did my R file go?
Try cleaning the project
Project>Clean
There are two things that can cause that:
There's a syntax error in one of your XML files, this causes the R file to not be generated.
The R file is not included in your class, make sure you import com.yourproject.R in the class.
Clean your project
the project will rebuild and R.java generated
Change the compiler the project will rebuild and R.java generated
Create New Project and copy all java file and resources into new project
