I updated Eclipse with the new SDK tools (rev. 23), but now when Eclipse starts I receive the error:
This Android SDK requires Android Developer Toolkit version 23.0.0 or above. Current version is 22.6.3.v201404151837-1123206. Please update ADT to the latest version.
No updates were found with "Check for updates". If I try "Install new software", I can see version 23, but I can't upgrade due to the following error:
Cannot complete the install because of a conflicting dependency.

After download of the last ADT from the web site, it seems there's another problem.
With SDK Tools rev. 23 proguard is not installed, the folder SDK dir/tools/proguard is missing, and other tools are missing. This version contains several bugs.
Google has released ADT v23.0.2. This solved many problems of previous ADT version 23.
Step-by-step:
Menu Help → Install New Software...
For "Work with", select the Android source https://dl-ssl.google.com/android/eclipse
Tick ADT v23.0 for installation, then click "Next"
Eclipse will show "Install Remediation Page" since there is conflict with previous version. (If it does not, see below.) Select "Update my installation to be compatible with items being installed" to uninstall the old version and install the new one. After that, proceed with the usual steps.
Note: When I installed the new version of ADT, I didn't include the new version of "Android Native Development Tools" package. Instead, I installed the rest of packages first, and then installed "Android Native Development Tools". For a reason, if I try to install all the new packages including "Android Native Development Tools", the installation fails.
If there is no "Remediation page", the only way to remove the ADT plugin from Eclipse is to go to menu Help → About Eclipse → Installation Details and uninstall from there. But there is a risk of uninstalling Eclipse itself.
Google response:
This is a packaging bug. The entire proguard file is missing. We'll have an update asap, but until then just copy it over from a previous version of the tools:
http://dl.google.com/android/android-sdk_r22.6.2-linux.tgz
http://dl.google.com/android/android-sdk_r22.6.2-windows.zip
http://dl.google.com/android/android-sdk_r22.6.2-macosx.zip
and copy over the following files:
tools/hprof-conv
tools/support/annotations.jar
tools/proguard
So at the end if you started from a new ADT copy by hand the files :)
Edit: with the latest ADT release, the bundle should now work with auto-update, so install these new versions:
linux 64 bit vm: http://dl.google.com/android/adt/adt-bundle-linux-x86_64-20140702.zip
linux 32 bit vm: http://dl.google.com/android/adt/adt-bundle-linux-x86-20140702.zip
mac: http://dl.google.com/android/adt/adt-bundle-mac-x86_64-20140702.zip
win32: http://dl.google.com/android/adt/adt-bundle-windows-x86-20140702.zip
win64: http://dl.google.com/android/adt/adt-bundle-windows-x86_64-20140702.zip
Don't try to upgrade from previous version because it doesn’t work at all.
If you have got problems with zipalign, it's now under build-tools and no more under tools/ so you can do a symbolic link or just copy it into the expected folder.
None of the other answers worked for me using the ADT bundle published on developer.android.com.
I ended up downloading the latest version of Eclipse (not the ADT bundle) and then installing the ADT plugin via menu Help → Install new software → entering https://dl-ssl.google.com/android/eclipse (mentioned by #RED_).
I also had to update my workspace to point to my previous workspace, and most things seemed to be restored.
On a side note: This seems like a good time to migrate to Android Studio...
NOTE: Use this approach with caution because this might break your Eclipse installation (see comments).
This might help you if you installed the ADT plugin manually. But if you are using the version of Eclipse from the Eclipse ADT Bundle the below steps could break your Eclipse installation, and you may not be able to use Eclipse again!
Go to
Menu Help → About Eclipse SDK → Installation Details.
Now you will see all 22.0 versions and then click Uninstall button at bottom.
After uninstallation goto:
Menu Help → Install New Software → enter http://dl-ssl.google.com/android/eclipse/
Then install all the things, and now it is ready.
I was updating my build server today and came across the same issue. It has been reported here:
https://code.google.com/p/android/issues/detail?id=72419
The fix is in progress and the work around according to the project manager is:
Please wait for an updated version within a day or two. Until then, your workaround is to do download one of
http://dl.google.com/android/android-sdk_r22.6.2-linux.tgz
http://dl.google.com/android/android-sdk_r22.6.2-windows.zip
http://dl.google.com/android/android-sdk_r22.6.2-macosx.zip
and copy over the following files:
tools/hprof-conv
tools/support/annotations.jar
tools/proguard
[edit]
zipalign was missing for me too, check to see if you need to copy this as well
It works for me :)
If for some reason you installed an ADT preview and need to revert back to the current stable, you can't use the dialog to install "new" software since what you want is actually an older one. Instead do this:
Open Help > About Eclipse... on Windows or Linux. On Mac, use the app's menu > About...
Click the "Installation Details" button.
Select the "Installation History" tab.
Select one of the previous configurations.
Click the "Revert" button at the bottom.
is what they are saying about this:
OK, guys, sorry about all this trouble, and we apologize for the messed up releases. Here's the summary:
There is no way to update an existing ADT bundle that you might have downloaded.
You can do one of two options:
Install Eclipse from eclipse.org and install ADT by pointing to the update site: https://dl-ssl.google.com/android/eclipse
Download bundles from here:
Linux 64-bit VM: http://dl.google.com/android/adt/adt-bundle-linux-x86_64-20140702.zip
Linux 32-bit VM: http://dl.google.com/android/adt/adt-bundle-linux-x86-20140702.zip

Windows 64-bit: http://dl.google.com/android/adt/adt-bundle-windows-x86_64-20140702.zip
Starting with ADT bundle 23.0.2, you should be able to update to future versions of ADT.
Source: https://code.google.com/p/android/issues/detail?id=72912
I have done following to resolve an issue.
Go to http://developer.android.com/sdk/installing/installing-adt.html and download the latest ADT ZIP file (at the bottom of page).
Go to Eclipse → menu Help → About Eclipse → Installation details
Delete Android DDM, Android Development Tools, Hierarchy Viewer, Native Development Tools, TraceView, etc., 22.X version.
Menu Help* → Install New Software → Add → Archive → *Select the downloaded ZIP file in step 1.
Select all the latest version of all 23 which I have deleted in step 3 and accept the license agreement.
Restart Eclipse, and it fixes my issue.
Only helped:
Fresh Eclipse installation (http://www.eclipse.org/downloads/packages/eclipse-ide-java-developers/lunar)
Help --> Install New Software --> https://dl-ssl.google.com/android/eclipse/
If you install a new Eclipse version it will work.
Here's what I did:
Installed the new Eclipse version, Luna
Made a backup of the current workspace.
Ran the new Eclipse, Luna, and updated the workspace
Installed the ADT plugin (Help -> Install New Software)
Restarted Eclipse
Done
There is a lot of confusion going around in this thread. There are two solutions depending on how you installed ADT.
If you installed the ADT plugin manually then I believe you can use the "Delete ADT" -> "Install New Software" approach.
If you are using the ADT Bundle then do not follow that solution! You will break Eclipse. Here is an update from a Google member - read #18:
https://code.google.com/p/android/issues/detail?id=72912
You must download a new version of the ADT-Bundle (yep, it's frustrating!).
Just uninstall the previous ADT.
Go to menu Help → About Eclipse → Installation Details
Uninstall all plugins which Id start with com.android.ide
Install ADT again from the update site.
DO NOT DO THIS
Warning: Please see the comments below this answer. These steps have had a negative impact for many people.
Click Help / Install new software...
Click on What is "already installed" (as in picture below)
In the new window you can uninstall the old ADT (uninstall Android Development Tools, Android DDMS, Android Hierarchy Viewer, Android TraceView, Android Native Development Tools and Tracer for OpenGL ES)
Restart Eclipse
Then again click on Help / Install New Software
Choose ADT... Install
I hope it helps!
After trying the approaches in other answers without success, I just installed a new bundle from http://developer.android.com/sdk/installing/index.html?pkg=adt and that worked fine.
Do the following:
As you don't want to re-download all the platforms again, copy the existing one from /OLD_ANDROID_SDK_PATH/sdk/platforms to /NEW_ANDROID_SDK_PATH/sdk/platforms.
When opening the new Eclipse from the recent downloaded bundle, make sure you reuse the previous 'workspace' folder. That will ensure that all your previous settings will be remembered.
After opening the new Eclipse on the previous workspace, please check if the used Android SDK is pointing to the new one (Eclipse preferences -> Android). It might be pointing to the old one, as you've reused the previews workspace settings.
With these steps, you should't have to reconfigure everything, and you won't need to spend time troubleshooting this BUG on this upgrade from Google Developers.
Good luck! ;-)
You need to uninstall the old version and install 23
uninstall:
Help > about Eclipse SDK > Installation Details
select Android related packages to uninstall
And then install V23.

I was getting the same "conflicting dependency" error on Mac OS X 10.9.3 and simply upgrading was not an option. What finally worked was downloading the latest Eclipse ADT bundle zip file from developer.android.com, extracting it and moving only "eclipse" folder to the place where my old eclipse folder was. (extracting the Eclipse ADT bundle zip file will give you "eclipse" and "sdk" folders).
If you decide to go the same route, first make sure you know what your Workspace path is. This can be found in Preferences. Then rename your old "eclipse" directory (not Eclipse.app) to something like eclipse-22.6.3, then move extracted "eclipse" folder into its place. Run new Eclipse.app inside, and when it asks you about Workspace, just enter the same path as you noted above. Or it can also be set later in Preferences.
Maybe worth adding is that to re-enable Android SDK Manager and Android Virtual Device Manager choose Window -> Customize Perspective -> Command Groups Availability and select Android SDK and AVD Manager. This will add these 2 items to the "Window" menu item for the current perspective (Java).
I didn't move the extracted "sdk" folder, because I already had sdk folder in the same directory as eclipse, which I have already updated to the latest Android tools. But if it makes you feel safer, you can also rename your old sdk folder (for backup purposes) and move the freshly extracted one into its place.
I faced the same problem and solved it. You need to uninstall the Android plugin entirely from within Eclipse (from the "about" section..), including trace view..
Then added the ADT Plugin again (https://dl-ssl.google.com/android/eclipse/) and install it.
The problem is solved!
I guess it's a bug with the SDK manager or ADT Plugin update mechanism...
How to update from 22.xx.x to 23.0.2 (my solution). This will beat the dependency issues.
I was suffering from this issue for days, and I have tried every single solution on this link, but no luck. I finally figured out a solution that actually works!
Please note that this solution works in Windows 7 (64 bit). It should probably work for other Windows operating systems.
Here we go:
download the latest ADT bundle from
http://developer.android.com/sdk/index.html#download
unzip it and open "eclipse" folder --> "plugins" folder
Now go to your old eclipse and open "eclipse" folder --> "plugins" folder, and copy everything inside.
Now paste them into the "plugins" folder of the (NEW ECLIPSE), but DO NOT overwrite anything.
While inside of the "plugins" folder of your new Eclipse, do the search. Type in 22. (notice 22 with a dot) and hit enter.
The search result will show up all the files or folders with .....22.6...... For example,
com.android.ide.eclipse.adt_**22.6.2**.v201403212031-1085508
Highlight all of these files/folders and hit delete key.
Make sure to update your old API/SDK to the latest version and load this sdk directory to work with your new eclipse.
or
You can watch this video, which shows you how to move all your SDK/API to your new SDK folder.
Link: https://www.youtube.com/watch?v=jPZpJdnbbN0
I have not tried to update from any other ADT versions, but I think it should work for any old ADT versions too.
Don't forget to backup stuff before attempting.
What I have just found is that you need to update your ADT plugin in your Eclipse (whether stand alone or ADT Bundle) before updating your build tool.
If your Eclipse installation points to the most recent Build Tool and your Eclipse is having ADT 22.x, it will show those errors.
What worked for me: (on Ubuntu 14.04 64-bit)
Installed an older version of Eclipse and ADT (from the Bundle)
This copy of Eclipse was pointing to an older SDK verion with old build tools (before 20)
Updated the ADT to v23 (via archive, in my case)
Pointed Eclipse to the latest version of build tools.
You may not have an older copy of Eclipse and Build tools, in that case you can uninstall latest build tool from SDK Manager and install the older copy.
Once everything starts working fine, do the above steps.
I am trying to upload older copies of such bundles somewhere on the Internet, will update the links here, once I am done uploading.
I found these instructions in a comment.
Download the newest version of ADT and use your existing workspace. This is actually the least pain-full upgrade you'll ever do. It didn't mess with the .android folder so I still had my original debug key. Only things missing were a couple of add ons I hardly ever use and they are easily installed into the new version.
Note don't install into your existing adt folder create a new folder so you can still fall back if the new install doesn't work.
On ADT-bundled Eclipse I had to first uninstall the ADT and then do a fresh install.
To remove the ADT plugin from Eclipse:
Go to menu Help → About Eclipse → Installation Details.
Select ADT plug-in, then click Uninstall.
After uninstallation install ADT from Help → Install new software.
For me it helped to delete Android 4.4W which is also API 20 and might be a cause for the conflict. So only install Android 4.4W or Android L until they fix it.
And (again this might only be for me) it only works in Android Studio not in Eclipse ...
I had to delete ADT and install it again.
However be warned, this caused me and one other person to have an annotations.jar missing errors in the Java Build path for certain projects, probably because it was trying to look for an old SDK, so upgrading projects is the next step I have to take.
The errors relate to libraries mostly, Google Play Services, Facebook SDK, ActionBarCompat.
For this step, you uninstall ADT, then put the URL back in to download them. The url is: https://dl-ssl.google.com/android/eclipse
I found a solution for the problem with "conflicting dependency". I don't have the same page of Daniel Díaz's response, but a page show "conflicting dependency", and I can't make anything.
The problem is that I'm not the owner of the file. Eclipse was installed in other session (on OS X). I have the right to read and write the Eclipse file, but I'm not the owner. Make a "chown" command on all Eclipse files to solve the problem. After, I have the same result as Daniel Diaz.
I hope this helps someone.
WARNING
There is now an update for ADT 23.0.1, but the Windows and Linux scripts are messed up, so wait with the upgrade!
You could check for example tools/proguard/bin/*.sh in http://dl.google.com/android/android-sdk_r23.0.1-windows.zip.
I did this to solve the same issue (in OS X):
Help > Install New Software > Add or select this repository "http://download.eclipse.org/eclipse/updates/4.3"
Under "Eclipse platform" select the newest version of Eclipse.
The installer will ask if you want to uninstall the ADT, click finish.
Restart Eclipse and install ONLY the ADT 23 using this repository: https://dl-ssl.google.com/android/eclipse.
Restart Eclipse and install DDMS, Hierarchy Viewer, Trace View etc.
Restart Eclipse again.
Hope it helps.
If Eclipse gives an error after uninstalling the ADT plugin from your Eclipse installation, try to edit file config.ini in the Eclipse folder → configuration. Find:
eclipse.application=
And change it to:
eclipse.application=org.eclipse.ui.ide.workbench
I hope it works for you too.
I simply went to my Android resources folder on my C:/ drive (C:/Android), deleted the 'eclipse' folder and all its contents. I downloaded Android Developer Tools once more and just moved over the 'eclipse' folder.
I started up and everything was fine; I had updated to version 23.
Hopefully this helps, possibly not suitable for everyone as some of you have Eclipse modifications but for someone who, like me, wanted a quick fix and get back to developing this seemed to be the easiest path.
I am using Eclipse v4.3 (Kepler), and this is how I solved my problem.
Goto menu Help → Install new software → click Add.
In the popup, give any name (I named it as Eclipse ADT Plugin), and in the link's place, use https://dl-ssl.google.com/android/eclipse/
Once you click OK, you will be displayed with new packages that will be installed and old packages that will be deleted. Don't worry about these packages. Click OK.
New packages will be installed, and this should solve your problem.
I am beginner in Android programming. My problem is, that I can not update ADT. The problem started, when after a long time I have updated in Android SDK Manager the Android SDK Tools. Then I was trying to import a project into the workspace. But I couldn't import that, because every time I clicked the Finish button, nothing happened. Then I closed Eclipse and opened it again, and showed me the following error:
I clicked on the Check for Updates, but it didn't find anything. On the Internet I have found an URL, so I clicked Help-->Install New Software...--> Add--> and pasted this URL. When I clicked Next, it showed me the list of items which I wanted to install and also an error:
Cannot complete the install because of a conflicting dependency.

I have also read somewhere, that I should try to replace the plugins folder with the updated plugins folder so I tried to rename "plugins" folder in the Eclipse folder to "pluginsx" and pasted the new one I have downloaded from the site. After this I couldn't open the Eclipse.
This site is also about the same problem as I have, and there is an answer which is accepted as the solution of the question. So I tried also to download, and copy those 3 things to folders which were mentioned in the comment below, but I have still the same problem, nothing changed.
So now I don't have any idea, how to fix this problem. Can anyone help me, please?
Thanks in advance.
Help-->Install New Software-->What is already installed?
Then, Select "Android DDMS, Andoid Devlopment Tools,Android Hierarcy Viewer, Android native Development Tools, Android Traceview, Tracer for OpenGL ES" and click Uninstall.
After all this step, try Add link (https://dl-ssl.google.com/android/eclipse/) and name is ADT Plugin. This link will get the latest ADT Plugin. In this way you reinstall the ADT.
None of these "update" alone answers worked for me.
The solution I used is to uninstall the ADT (from Uninstalling Android ADT)
Help > About Eclipse > Installation Details
Select all of the Android modules (prefixed with com.android.ide...)
and delete them (Uninstall...) and re-add the libraries from the
help > Install new software
As listed above....
The only solution that worked to me was to download the current Eclipse ADT bundle from the Android site
After download it, I copied my current sdk to a folder like .../development/sdk. Then I deleted the sdk that came with this new Bundle.
I put ADT Bundle in .../development/adt-bundle-....
After start it, you jave to inform the new sdk location in Window > Preferences > Android, so in SDK Location you put the new sdk path. In my case: .../development/sdk.
Of course, you can put the sdk folder inside the new ADT Bundle folder, but I do this way, because I use Android Studio as well, so I point the two IDEs to the same SDK.
After finish this and be sure everything is working I deleted the old ADT Bundle folder.
I had the same issue and the following solution worked for me.
I had installed SDK Platform of M Preview while my ADT was of version 22.
So I just uninstalled SDK Platform of M preview and installed SDK platform of API level 22 from SDK Manager.
This worked for me.
this solution works.!!!!!!!
Open eclipse> Help>about eclipse>Installation
uninstall the component the are included to the .zip file you downloaded. download like below.
(credit to mr.zakimark
I found it simpler at times to first uninstall all the 7 components:
-Android DDMS
-Andoid Devlopment Tools
-Android Hierarcy Viewer
-Android Native Development Tools
-Android Traceview
-Tracer for OpenGL ES
-Google App Engine Tools for Android(If installed)
Then download the latest ZIP/Archive.
Install the Archive from Help->Install New Software->Add->Archive
Select the downloaded ZIP, provide a name for it and follow the standard installation process.
Installing ADT is a major problem specially when updating. Also sometimes it's just a pain to install ADT by providing the direct link. Often Eclipse will stall while displaying "Calculating requirements and dependencies".
I found it simpler at times to first uninstall all the 7 components:
-Android DDMS
-Andoid Devlopment Tools
-Android Hierarcy Viewer

Then download the latest ZIP/Archive.
Install the Archive from Help->Install New Software->Add->Archive
Select the downloaded ZIP, provide a name for it and follow the standard installation process.
I couldn't uninstall the old ADT plugins from the 'Help->Installation Details` page because the 'Uninstall...' button was disabled when I selected any of the modules.
Also, because the ADT bundle is no longer available to download, reinstalling was not an option.
What worked for me was to install the basic Eclipse environment using the Eclipse Installer from here. In the installer, I selected 'Advanced Mode...' from the hamburger menu, and then selected just the 'Eclipse Platform' to install, i.e. just the core tools. I think that this is only possible using the installer.
After eclipse was installed, I installed all the ADT plugins using 'Help->Install New Software' and using link https://dl-ssl.google.com/android/eclipse/.
YMMV, but this worked for me.
When i create a new android application project in eclipse the gen - file is empty.
I found out I have to install android sdk build-tools but in the tools folder there's just the Android SDK tools and the android platform tools.
It's revision 22
You need to start the SDK Manager and download the build-tools from there.
You'll need to update the ADT (Android Development Tools) in Eclipse to the newest version first (see this post for more info on how to do this). What also worked for me was to get the Android API and all the extras updated before I could update the build-tools.
May be you can use ADT bundle (http://developer.android.com/sdk/index.html) and avoid the manual installing of SDK and eclipse plugins. All you need to do is to download it, unzip it and start using eclipse to create your apps.
I had the same concern.
You may be looking in the wrong sdk folder.
I had two on my machine. One from before I started using the ADT Bundle. when you open Eclipse sometimes it opens the SDK manager for the wrong SDK. Open it manually from the bundle you downloaded.
Hope this helps.
I hope that this will help you and others. I had downloaded the "build tools" myself and placed in "Android home". I even used some of the tools several times but could not link them to other tools listed under sdkmanager. After much searching, I found that;
deleting the old tools that I installed manually, and
re-installing the same package version of the tools using the sdkmanager
helped me. After this the tools showed up under the list of packages in the sdkmanager. I had not noticed that my "build tools" were not listed on sdkmanager before as I had installed them myself and barely used the manager.
If you don't want to go through this (reinstall) hassle, I noticed that the only difference between the auto install and manual is that sdkmanager kept the package version directory structure for the "build tools". For example, if you download version 4.0.5, then it will be in
