I have an old Android project sitting in another laptop. I try not to change its contents for when I have to look at its codes. But when I tried to look at it, I cannot seem to import it on my workspace. I do not have any existing project in my workspace. I have also tried deleting my "workspace" folder so I could start anew, but it still won't work. There are no error messages, it just won't import.
The same has happened to me.
The solution was to create a new project, add the classes from the old project and all necessary libs.
Have you experience yourself this solution? I know it is not the most correct, but if consigas not otherwise experience. Can you then know which classes have errors.

I'm trying to install the ActionBar-PullToRefresh whithout the gradle. I download the source and I go on Import->Existing Android Code Into Workspace but for a reason I don't know it doesn't let me to import it (see image below). I see other posts and the solution was to import it like this way but for me doesn't work. I'm new and I'm sorry for this dump question. Thanks :)
Because you already have projects named main and MainActivity in your workspace.
Click on every projects path and then click on it's name and change it.
I ma trying to open the source code of Gallery2 application in of Android in Eclipse and for some reason I am not able to open it.
I did Open> Android project from the existing code and selected the Gallery2 folder that I downloaded. As soon as I do that, i see the following screen:
As we can see that next button is disabled, Finish button is disabled and it says "Select atleast one project even though the project is selected". I am not sure what to do.
Or let me ask the question another way. I have successfully imported project into my workspace. What do I do now? I am fron Visual Studio world and ideally I should be looking for a solution file and that will open the entire project. How does that happen with java Android file?
Any ideas?
Because there is already project whose name is same GalleryActivity/Gallery2 or project which have same package name already imported in your eclipse workspace.
Check all the imported projects in your eclipse project explorer
This similiar error happened to me when I imported a standard Java project, I knew it was a java project but Eclipse didn't think so. It turned out that my project was missing the project.properties file and because of that Eclipse didn't recognize my project as a Java project. In the end I imported it as default project and added java facets to it, that did the trick. I don't know if this is your case but it may be worth to have a look at it, eclipse is a bit pedantic when it comes to things like this.
you have already imported same named project in your workspace. so first check your workspace and if exists delete it. or create another workspace and try to import the project
I have map Project in Eclipse IDE and I Cleaned It From Project Menu.It deleted mY BIN Folder and also Gen Folder.Now I Have tried Much BY Build Manually and also from Android Toold To Fix Project Properties But It is Not fixing the Problem and In Source Files R is Red underlined and Bin and Gen Folder are Not Being Created again.Please any oNe Help me to To Get Out OF this issue.
There may be Some Reasons :-
1.from Project-> checked Build Automatically.
2.There Should not any error in your xml otherwise R file will not build automatically.
3.Refresh the project & Restart eclipse.
First backup(e.g. zip) your whole workspace before you start experimenting. Then try to remove IDE specific files e.g. .project .classpath and setup it again. If it fails create new project with similar configuration and simply copy your libraries and source code into new project. Eclipse IDE is pure magic sometimes.
If you have imported this project, then try import as a general project, not as android project. then in build path see if all libraries are present, then run as android application
you have to try till you succeed process.
Try following steps:-
Make sure there is no error any any of your .xml files .. check in
Problem section..
Make sure all your impoert are correct, Eclipse sometimes do import
android.R; on its own, so remove that..
If that doesnt succed make some changes in Manifest file say remove a
word save it then again add that word save it.. I know it doesnot
make sence as code but making changes in Manifest files rebuilds the
workspace an so is the auto generated files. then clean build your
project.
Restart Eclipse as last resort..
try the following steps to help us
remove if imported import android.R; and after like example if your application package name is com.example.project you need import like import com.example.project.R;
I copied my program at work to another computer so I can work on it here. When I try to create New project from existing code I get the dreaded R. cannot be resolved to a variable.
Apparently, R.java is supposed to be in the gen folder but it isn't. Eclipse tells me to import R.java but we all know that isn't correct.
None of the many answers I have seen explain or solve my problem. Any help is greatly appreciated.
I've cleaned the project - as advised - many times after doing other things but it does nothing.
try doing something like this type R and give a control + space. It will give few suggestions among which you may have the R.java file related to your project. Import that R instead of the default android.R . Before doing all these check if your project shows any errors in the xml files. If you have any errors in any of your xml files the R.java file will not be created
R. java gets generated .(Thats what gen stands for 'gen folder') Do not import R.java as suggested by Android, clean your project and rebuild it and the R.java file will be created in the gen folder unless your project has errors.
Let me know how it goes
Do not modify the source (such as importing R.java) if it worked on another computer.
Right click the project and select Android Tools -> Fix Project Properties.
If you do not have errors in your xml files, this should work.
EDIT:
If you do not mind other IDEs, I think IntelliJ IDEA is good for Android developing.(compared to Eclipse) and it should save a lot problems.
Maybe you can also try doing this instead of creating 'New project from existing code':
In your eclipse go to:
File -> Import -> General -> Existing Projects into Workspace -> browse to your project -> Finish
Hope that helps. :)
Try importing your R class manually. Go to a java file in one of your activities and try this in your import statements.
import com.yourpackage.name.R;
Aside from the other solutions, try changing the build of your app through
properties > Android
then revert it back to your original build.
or just in case, try checking your layout or res folder
If I'm not mistaken, R couldn't be built if there is something wrong with the res folder.
Aside from the other solutions, try to delete the package that is causing the problem under the "gen" folder and let eclipse rebuild it.
i almost face the same problem again. Few minutes ago i posted a question concerning that, the
R.layout.mylayout
is not recognised by eclipse despite that, the layout folder contains my xml file and the layout folder is located inside the res folder. the answer was to delete the R.java from the gen folder and clean the project and restart the workspace.
Now, i face the same problem again despite that i followed the previous steps to solve the error but the error which is that, the
R.layout.mylayout
is not recognise still exist and there is also exclaimation mark beside the project name.
is there any other ways to solve this problem
Project - > Clean
Select "Build Automatically" so that every time you clean the project, it will be rebuilt. And yeah, make sure you are saving the file before cleaning it (I know it is weird but sometimes the errors refuse to go away until you save it and then Clean it). Make sure that there is no error in the files in the layout folder, as it sometimes prevents the auto-generation of the code in R.java
Also, make sure that your code in MainActivity.java does not have import android.R. Eclipse tends to add that when you are managing the imports.
Please check you import statements.... If you have by mistake imported the android.R , then please remove it at once.... and then clean the project and see how it works...
Run the Lint tool. Right click your project and check under Android tools. check what is the issue using that.
