This is a dumb newbie question, but one that is driving me nuts.
I have an Android project being developed on Eclipse with two source files. Eclipse for some reason decided I didn't need one of the files and removed it from the project (i.e., I pushed the wrong key at the wrong moment). Now I only have one source file in my project. The lost source file is still there in the directory, but Eclipse just doesn't recognize it as part of the project. How do I get it back?
MY first suggestion is press F5 on the source folder.
Second suggestion, right click the project folder->Properties->Java Build Path -> Source - expand ".../src" and ensure your source file is not under the Excluded option.
Try dragging the file out of your folder onto the desktop, and then drag it from the desktop into your source folder in eclipse. I've had a handful of different situations where this was necessary.

I am using eclipse juno -adt tool Eclipse Platform Version: 4.2.1.
i lost all projects from eclipse project explorer .they doesnt have single line of code. all projects in work space folder have 0kb data(user/workplace). is it possible to restore the complete projects from .metdata or work space runtime.
cd ~/Documents/workspace/.metalog/.plugins
rm -rf org.eclipse.core.resources
i have tried above commands but rm is not recognized .how can i setup path for eclipse.. please help me out..
I don't think that you can get it back, ask experts if you still don't get you may try this, there is 50% chance that you may get .java files atleast.
1) Download recuva
2) Open recuva and select All contents.
3) Locate the path to your workspace.
4) "Deep scan" that may take hours, when you get all the deleted data back, extract .java, .xml files from them.
5) Create a new workspace and add those files, and you can reprogram Manifist files manually. (If you are working on android)
Try manually separating metadata for each package from the metadata folder in your workspace. Once you do that put the corresponding metadata and packages to a separate folder and then in your eclipse choose workspace window select the folder which you created for individual packages. It'll work. All the best.
I have just experienced the same problem. The entire project displays all the files but they are all 0 bytes. Most recent bit bucket sync is not very recent. After cursing and kicking things, I had some luck with recuva. Since it is an android project, I have the latest apk I had installed in my phone yesterday as I was doing the test, dex2Jar and JD-GUI helped a little her, but there are still mountains of code I will never get back.
I'm using Eclipse (4.2.1 Juno) on Windows 7 for my Android 2.2 project. I have several PNG resources in my drawable folders, and I'm finding that if I edit my PNG files (Paint/Photoshop etc) Eclipse doesn't recognise the file has changed and the ADT graphical layout designer still displays the old version of the image. I've tried refreshing the project folders list, tried doing a Project->Clean but neither has any affect. The only way I've found of getting Eclipse to recognise the new image version is to exit completely and restart which is a pain.
Is there some setting I can use to tell Eclipse not to 'cache' the images and always read the latest version off disk?
Try in Eclipse Project -> Clean then select your project. This will delete your R.java file and will generate new one.
That is a common problem of Eclipse that it doesn't recognize external changes for files in the workspace. The only thing I have found out to remedy this problem a little (apart from refreshing like crazy), are the refresh settings in external tools configurations. That is, if you run for example an Ant build, you can tell eclipse to refresh the workspace or specific resources afterwards. I don't know of any automatic way to do this though.
you should try saving all the unsaved resources and files after adding images ,than try out again.try cleaning both options with cleaning your single working project and with cleaning all projects.
I don't know of an automatic setting, but I have found a relatively simple manual action that seems effective. I was having the same trouble as you; now the following procedure seems to work consistently for me, with Eclipse Juno 4.2.1.
Click on the "res" folder to select it, then press F5 to refresh. Also make sure your PNG file timestamps have been touched.
Resources cached in bin\res folder.
Create script which delete folder bin\res with all content.
Add this script as external tool in builder list.
Set position in builder list - after CDT builder. Second position in list. If no CDT builder - set it first.
Enjoy.
I've quite new to Android development and specially Eclipse.
I'm busy on a project called, say 'HelloEclipse'. I've had some major changes ahead, in which I had to some very big changes.
So I made a zip file of c:\workspace\HelloEclipse, placed that in a save place. Went on to work on my project. Few hours later, I wanted to go back to the saved situation. Closed Ecplise, rebooted my computer, because I wanted to make sure there were no locked files. Deleted the old c:\workspace\HelloEclipse folder, place the version out of the ZIP file back.
This resulted in a totally corrupted workspace status. Could not go foward, nor backward. I've ended up, creating a new project, and pasted in everything, took me hours. I think this is quite stupid Eclipse behavior. I've also tried ot, export/import with a archive from out of Eclipse, also not succesfull.
So the two questions;
How am I suppose to save projects (without installing anything like subversion)?
Why is saving the files not enough, and why does that make Eclipse barf?
Thanks in advance!

In eclipse if you want to reimport an old project from a ZIP, don't just copy the project files to the workspace, instead, extract the files to a normal dir outside the workspace.
Open Eclipse normally and select File>New Project>Android Project, just as you would to to create a new Android project, but then in the new android project window, you have a radio button giving you the choice to Create project from existing source, point it to the directory where you have extracted your old project and it should be re-imported to the WorkSpace alright.
Or do File>Import>Import existing project into workspace.
But in any case, don't put the files in the workspace manually to avoid conflicts, Eclipse will copy the files it needs itself upon importing.
There are hidden workspace files that you may have missed -- specifically, .classpath and .project. That said, it's a lot easier to make a backup copy (for example, of a released version so you can continue developing while supporting the release) by simply right-clicking on the top-level of the project in Eclipse and selecting Copy, then right-clicking and selecting Paste. The result will be a copy of the project after an opportunity to name the copy.
If you want to zip projects, you can do that by exporting them. If you want to delete existing projects, you should do that from inside Eclipse with a right-click. You can import the zip you previously exported.
If by save, you meant backing up the best something would be to create a local repository. If I were you, I would backup my code in an online repository too; to save it from hardware crashes or other disasters.
In your problem, you could have tried deleting the project alone and import the backup copy(from the zipped file) instead of deleting the entire workspace. Can't pinpoint the exact reason of why eclipse barfed but maybe because it messed up the workspace settings for eclipse. On a related note, I found this on the net.
Eclipse is rather troublesome at times but AFAIK it's the best IDE for android.
First of all, after several months of developing with eclipse I moved to IntelliJ (they have a community edition) and I found it much much better.
In intelliJ you can save local history, for example, you can set-up a label and go back to that label whenever you like without losing anything.
As for eclipse, you probably didn't zip some hidden files or something.
In addition, I remember having some similar problem, I had to resync the files with the project, try this one
Good Luck
I do the same thing with my projects. Instead of going through windows explorer to copy the files, I find copying the entire project from within Eclipse (right click the project in the explorer window pane, click copy, then click outside of the project and click paste) works just fine. When you paste it, you can specify a new save location and project name, which can be your backup space. Then you can switch between versions of the project no problem.
i was developing Android applications on my macbook pro after which i had to shift to the iMac at work. So i copied my Eclipse directory and the android sdk and the workspace and pasted it on the iMac at work.
I have set the Android sdk root inside the preferences of the Eclipse but the workspace is not loading inside my package explorer?
i have made the workspace folder inside the documents folder where it was in my macbook pro.
When Eclipse starts i choose the specified path of my workspace and then start eclipse.
Why are my workspace projects not being available in my package explorer?
thank you in advance.
EDIT:
i imported the project into my workspace. But there was .classpath 5.0 compatibility error, so i right clicked on my project and clicked android tools -> fix project properties. That error regarding .class path compatibility went away but a new error came in which the whole src folder inside my project has errors.. i mean each and every class.
And the error is regarding classes that come in the Android library...for eg. it is giving me error in the getCount method saying there is no such method in a class i used to extend the BaseAdapter class..what is going wrong here?
i have cleaned my project several times, but no change.
I just experienced something similar - had to create a new workspace and import the projects from my previous workspace to make it work. Pretty annoying, but it seems to be a bug in Eclipse.
Make sure that the build path of the project links correctly to the Android SDK. Right click on the project and choose configure build path and make sure that there are no red marks there.
Your project list is stored at .metadata.plugins\org.eclipse.core.resources\projects\, so you might want check that file to see if your projects are there.
from : Eclipse - No project visible in explorer
What helped me is i went to the package explorer and on the right site click the menu i.e. go to Filters -> Non Shared Projects. Remove that check mark. Then i see all projects.
Well, I hosed up my Android development PC, but didn't care all that much since I really needed a newer, much faster PC for this work. And here I am now with a high-end Windows 7 64-bit box.
Eclipse and all the Android components are up and running, but the one thing I'm having trouble with is how to get my previous project into the new workspace. I copied over my entire old workspace directory from the old disk and made that my Eclipse workspace, but it doesn't automatically see the projects that are there. I tried creating a new Android project "from existing source", but it complained about having "overlapping projects" or some such.
Is there a way to have it recognize the existing project files, or should I move them somewhere else, create the project from scratch, and then copy the old files back into the project tree? Or any other solutions?
A super easy way is by just doing an Import.
Select File Import.
Select Existing Projects Into Workspace and click next.
Select the directory of the project file.
Click Finish.
You will have to do this for each project. Note, that you may need to remove the project folder that you copied into the workspace manually, because this procedure will automatically copy the folder and hierarchy for you.
I used this method to code on my home machine as well as a development environment running from a live CD while attending classes in the computer lab.
Get Dropbox.
Put your workspace in a Dropbox folder.
Point the new machine's Eclipse install to your
Dropbox workspace folder after it
has updated itself.
Get back to coding.
Hope this works for you. It did for me.
There was one other complication. On my "old" PC I had been using Eclipse Helios, which apparently has some minor compatibility issues with ADT, so on my new PC I went with Galileo instead, and there might be some differences in existing files in the project directory.
In any case, what I did was to move my old project directory to a temp location, create a new project in Eclipse with the same name and basic settings, close Eclipse, copy my whole directory tree back into the new project directories, and then restart Eclipse. Eclipse bitched a bit about something, then went ahead and rebuilt everything.
I'm back in business! Thanks for all the responses.
BTW, the entire install process took a long time since I wasn't sure whether to install 64-bit Java or 32-bit (32-bit was required), etc. But it's nice to be running on a clean, fast PC instead of one that's been accumulating general crud for several years.
Move each of the projects in your hard disk to the new PC's workspace, or wherever you want to have them. Do not copy the metadata folder!. Then create new projects from existing sources (yes, you'll have to manually do this for each of the projects)

I know that this is old question but it is a issue I ran into when moving my project over from my home theater PC to my new laptop so I can leave my HTPC to doing HTPC things. Anyways what I did was I imported my project from over the computer over the network to my new laptop using new android project from existing code. The files where populated but it changed my root folder name. Being OCD I wanted to change the name of the root folder back to what I had on the other machine. I found if I right clicked the item in the project tree and selected refactor I could rename it back to what it was on my HTPC. This then resulted in my laptop having a exact working copy of the code so I can program from here.
You can copy whole Workspace just through import>General>Existing Projects into Workspace>Select root Directory>finish
Have you checked if the export/import eclipse mechanim works fine with 2 linked projects: android and app engine?
