From what I read, this error could be caused by duplicate references to classes existing in diff jar files and that seemed to be the case after I fiddled with the Build Path. BUT, all I have was the android.jar and the android-support-v4.jar on my Build path and under the Referenced libraries which I need to get a clean build.
I cleaned the project, deleted the R.java, closed and reopened the project but am still getting this right off the bet. What else can I do to fix this? I need both .jar files and they are the only ones included in my project.

Ill-advised or mistaken usage of a core class (java.* or javax.*)

This is often due to inadvertently including a core library file

going on.
However, you might actually be trying to define a class in a core

It is also often of questionable legality.
If you really intend to build a core library -- which is only

the "--core-library" option to suppress this error message.
If you go ahead and use "--core-library" but are in fact

I had the same problem while trying to run an example app written for android 3 under android 4. I commented-out the body of every method in every class and tried to remove the android.jar from the classpath and I don't get the error message anymore. And it works even when I comment-in the code previously out-commented... strange :( Unfortunately I'm not sure if this is the proper solution since I get a NPE while trying to run the app in question. What about you?
I have faced with the same problem, and I realized that I have added Android library twice, also the JRE environment. Just make sure that Java build path of the project only contains one Android platform as the library, and not JRE. This should resolve the issue.
Remove any other library or jar files that you might be using apart from the android library. Chances are you might be using the Android library and also have added the jar for android from "Add Jar" option. If so, remove the additional jar. After that, a clean build should solve your problem.

this error only appears when run my project. I search long time to the right solution but all possible solutions don't work. I use android 4.0 and Eclipse 3.6,now
by the way, this project worked in Android 2.1 but in Android 4.0 No!!!
Your package name starts with java, which is reserved for core Java packages. You should rename your package if at all possible.
I was getting this because I had manually added android.jar to the build libraries because it was saying it wasn't finding the android libraries. The fix was to...
Remove android.jar from the build libraries
Right click on the project, go to "Android Tools", and select "Fix Project Properties"
Hope this helps.
You have to check that your project (or dependencies libraries) doesn't contain android.jar in build path (Project>Properties>Java Build Path>Order and Export).
If your main project contains android.jar in Android Private Libraries then you have to check build path for all libraries which were added to your project and remove android.jar from build path.
Modify the error caused by the jar package's scope attribute, from compile-> provided, this operation can be modified in File-> Project Structure-> Dependencies or in the project view app folder in the build.gradle file there dependencies , The corresponding jar package compile modified

Find another LDAP library, then, one that is not in the javax namespace. What you want to do with this JAR is not possible.
Add the dex parameter --core-library to the [ANDROID_SDK]\platform-tools\dx.bat.
Change line ~59 of dx.bat: 'set params=' to 'set params=--core-library'
This enables the Android build process to allow including javax pacakges.
Like the error message says:
move the classes in question into your own package namespace.
[...] JarJar is a tool that may help you in this endeavor.
Repackage the JNDI code into your own namespace, by using JarJar. Then rely on your new jar instead.

Android framework do not allow addition of JAVA core libraries in your project as external jars.
Heres how you can add libraries to your application:
Open project properties by right clicking project and selecting properties
Select JAVA build path on the left pane
Select Libraries tab from right side
Click add Library button
Select JRE system library and add required package.
I was facing the same problem, and noticed that I had added the system JRE library as one of the build path dependencies. However, the problem did not go after removing it.
I then removed the android.jar file as build path dependency, and it started working. Might be it was conflicting with an include from one of the other project dependencies, since the project was dependent on other android projects.
For people not working in english, it could also be your project name containing special characters (éàè...). I had the same problem, renamed my projects (with F2) and it worked.
I got rid of this error by checking the project dependencies and removing the Android dependencies.
In Eclipse:
Right click on the project -> properties->Java Build Path -> Libraries and there I removed the android dependencies
Check the box of System Library when you add the external jar files through Build Path--Add Libraries--User Library--User Libraries--new
I had same problem and after a couple of day of search and fight i found this thread. It does not solved my problems but helps me to find the solution.
I do this steps mentioned above:
Open project properties by right clicking project and selecting
properties.
I saw I had Android 2.1 library and Android 1.6 library.
Removed all libraries.
Changed the Android version of my project from 1.6 to 2.2.1
Clean the project
This solved my problem. The application now is working.
BTW, the application I was trying is an Android auto-answer (http://code.google.com/p/auto-answer/source/browse#svn%2Ftrunk%2Fres%2Fdrawable-hdpi)
Removing SPACES from an imported project name fixed the problem for me.
