So after creating a new project, this is what I'm met with. When I import the project to eclipse, it's still a rar file, rather than an actual project that I can expand.
Here's a picture of what I just described:
How do I go about fixing this? I read that I need to go into the directory and make it so that "write" is enabled, so it can create it, but that option was already checked. So I'm confused on what my next step should be.

I normally only use Eclipse just to code in Java for class, but today I decided to use it for my own personal projects. I didn't download anything funky and essentially only used FileWriter, java.util, java.io, and ArrayLists.
Suddenly, after running some code, I was told that Eclipse was no longer responding and had to force quit the program.
Afterward, I couldn't open Eclipse again because the workspace was currently in use.
I've looked up this problem numerous times, and what a lot of people were saying was to end Eclipse through the Task Manager and then go into the metadata file and then delete the .lock file, which I did. However, every time I opened Eclipse again, the program would load up, but there would be no workspace for me to work on. I'd try clicking the icon again, and now the "workspace was currently in use" window would pop up, and I'd go and see that the .lock file had reappeared in the metadata file, again, even though I'd deleted it.
I read somewhere else that another option was to relocate the metadata file, open and close Eclipse, and then overwrite the new metadata file, and it still hasn't worked, considering the .lock file ends up in the metadata again, somehow.
Is there any way I can fix this or am I just better off reinstalling Eclipse?
Thank you for any help, and sorry if this is very simple—I'm still very new to all this!
II updated AS to the latest stable build and all of my projects melted down. Only Java files in the main directory (com.company.app) can find R.java as intended. ALL of my subdirs can't find it. I did not have to import R.java before the update. I rebuilt my projects from scratch, restored backups, copy-paste to new projects from the backups, reinstalled AS, restarted PC, invalidated caches and restart, cleaned, literally every go to insta-fix-it solution that the internet always recommends and still I can't get this to work.
Can someone tell me how my subdirectories cant find R.java but other files in my main directory can? Is this a feature change in AS or something? Are we now supposed to import R.java? There are no XML errors. My project built before I moved any subdirectory files back to my main package. The package name exactly matches the one in my manifest.
Edit 1: I can rebuild my project and make R.java. The main package files still see it without the import, but the subdirs can't find it.
Edit 2: I can move a file from my main package to a subdir and it still finds R.java. This appears to be a compiler glitch.
Edit 3: Importing R.java makes the errors go away so I guess that is a solution. I am leaving the question open because this makes no logical sense.
You need to understand how App resources work.
When you build your android project, all of your resources in /res folder will be mapped automatically in generated your.package.names.R class.
Now you want to access the resources through the class. It's only make sense when you need to import the file when you use it in different package.
I had this issue, even though the error wasn't being underlined in red there was an error in my strings.xml. Go to Values->strings.xml and check if you duplicated any strings.
I am just starting off in Java and trying to follow buckythenewboston on you tube. I have java and eclipse neon both downloaded correctly. However, when I create a new project like he showed in the video, I click finish and nothing shows up, in the video it showed on the side there should be a like java symbol with the name of the project I created. Well nothing happens it is blank on my screen. I tried opening a file from the work space in my C drive and that doesn't work either as nothing shows up so I can create a class. I know there is a couple of forum questions with similar title but that is different I think as they can at least get code in where I can't. Any explanation as what is going on would be helpful. I also tried to go to file-import-existing project... but the existing project part isn't an option.
Thanks in advance.
go into your workspace directory and delete .metadata folder, then restart eclipse

When I create new Project in Eclipse, it displays the Desktop Manager beside the project name by default. How can I get rid of it?
If I understand your problem correctly, you're seeing the file location next to the file name. It looks something like this, perhaps?
There are a handful of ways to get rid of the location tag, but the most correct one (the one Eclipse wants you to use) is for you to put the project in the default location.
That results in a project name having no location tag. It also helps Eclipse find your projects later.
A caveat: since I do not have a screenshot of your problem and I do not know which Eclipse version you are using, nor what compoents you've added, I might be thinking of the wrong tag. If so, please add those details and I'll continue trying to help.
I'm using eclipse and a problem confused me. I downloaded the project from svn and for the first time I tried to do the debug, "ClassNotFoundException" occurred. Even the file is in my project. So I added the file path and then I could do the dubug, BUT instead of the original file, the debug is executed in another file whose icon is a light blue "J".
As you can see in the image, the left one is the original file, the right one is where the debug is executed. The right icon is light blue. I think it indicate that the file is not in the project.
Now there are two problems, the first one is sometimes the "light blue" code is not the newest. The other problem is I cannot watch the expressions in the file.
Does anyone know how can I solve these problems? Thank you guys!
This could be due to build path, check the order of classpath entries , remove the library if you have added original project as a dependency.
