Can't update ADT plugin in Eclipse to version 23.0.0 or above

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.
Software being installed: Tracer for OpenGL ES 23.0.0.1245622 (com.android.ide.eclipse.gldebugger.feature.feature.group 23.0.0.1245622)

Only one of the following can be installed at once:

To: com.android.ide.eclipse.gldebugger [21.0.0.v201210310015-519525]
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.

Trying to update ADT - receiving "conflicting dependency" error

I've had a series of problems ever since I tried to import an android project.
The location of my SDK hasn't been set up in preferences (even though it had been before and ADT was working perfectly fine).
When I try to set the path to the sdk folder, it says
This Android SDK requires Android Developer Toolkit version 23.0.0 or above. Current version is 22.6.2.v201403212031-1085508. Please update ADT to the latest version.
So I try to update Eclipse by the following as suggested on another SO post (since "Check for updates" keeps telling me that there are no updates available:
Help -> Install new software -> p2repo - https://dl-ssl.google.com/android/eclipse/ -> Check developer tools -> Next
And that's where I get the following error:
Cannot complete the install because of a conflicting dependency.

How can I successfully get around these errors and update eclipse?

Just uninstall current ADT version is 22.6.2.v201403212031-1085508 by going to Help>Installation Details> installed software and then select ADT(old version)> click uninstall. Now reinstall latest ADT. This way, I was able to update ADT to current version, hope it helps.
Note: This won't work on adt-bundle.

Uninstall all the conflicting components.
In my case, Open-GL, DDMS, ADT etc were conflicting with the update.
So i uninstalled all of these, using..
Help-> About Eclipse SDK->Installation details-> select the component to uninstall-> uninstall
Then update your ADT.
Help->Install New software-> Select the Adt update site(https://dl-ssl.google.com/android/eclipse/ if not present add it) in available s/w sites.
And update the ADT.

TODAY, I got the same error as you:
This Android SDK requires Android Developer Toolkit version 23.0.0 or above. Current version is 22.6.2.v201403212031-1085508. Please update ADT to the latest version.
YOUR MESSAGE:
This Android SDK requires Android Developer Toolkit version 23.0.0 or above. Current version is 22.6.2.v201403212031-1085508. Please update ADT to the latest version.
I fixed it in 5 minutes:
1-Make sure you still have the zip file (me it's "adt-bundle-windows-x86_64-20140321")
2-Copy the contents of the zip where you want it to be
3-It's like 1.30 GB (I think), so depending on your computer it could take a few minutes
4-Once it's copied, open it.
5-Go in the eclipse folder, then open the eclipse application (you can even pin it to the taskbar if you use it a lot)
I had this problem a few times, and this always works for me.

For Sanjay Manohar:
Basically, when you downloaded eclipse, it was in a zip file. You needed to extract the files in order to use its content. The file that I downloaded was named "adt-bundle-windows-x86_64-20140321" and I got it from "https://developer.android.com/training/basics/firstapp/index.html".
If you are using eclipse, you probably have the zip file in your downloads, so no need to download it again.
If I was you, I would make a file named "ANDROID" and in it place the zip file (to use as a future backup if you have similar problems)
I would also create a folder named workspace for all my projects, and a folder named ADT in which I would extract the contents of the zip file.
This would be the folders inside "ANDROID":
-ADT (->contains the extracted files of the zip file "adt-bundle-windows-x86_64-20140321")
-workspace (->contains my projects)
-adt-bundle-windows-x86_64-20140321 (->the zip file)
Sorry for creating a new answer, I don't have the reputation...

Just select ADT from Developer tools drop down

Android Development Tool 23.0.0 and Android L Update error in eclipse [duplicate]

This question already has answers here:

Closed 8 years ago.
I updated my SDK with latest release of Android L and restarted my eclipse i.e running on ADT V.22. But when I Check for update from
Hep -> Check for updates, it says No updates were found.
I manually tried to download ADT bundle from official website and tried to install ADT-23.0.0.zip from Help -> Install New Software and described installation guide over site, but it gave me error

I tired various solution provided earlier for killing adb server and restarting again using adb kill-server command.
Can anyone resolve or guide me how to build and compile my existing projects with this new SDK update in eclipse.

I had the same problem and just solved it. what I did is uninstall entirely the android plugin from eclipse (from the "about" section..) including trace view..
Do not restart eclipse at this point!
then added again the ADT Plugin (https://dl-ssl.google.com/android/eclipse/)
the problem solved!
I guess it's a bug with the SDK manager or ADT Plugin update mechanism..

It saves my day...!
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.

I am depending on this article
How to install plugin for Eclipse from .zip
and I made it sorta work. still needs some fix from me. I'll update soon.
This is based on the idea of opening the ADT plugin zip file and copy it's contents by hand , an old fashioned copy-paste method. I still could not yet make it well configured, but the tools do work.
Don't forget to uninstall older ADT before doing this.

I had the same problem, finally I had to download a new ADT from http://developer.android.com/sdk/index.html is faster than trying to fight vs dependencies or adt versions.

What should I do now?

If you have a conflict with the previous version:
Select Help > Install New Software
Click on already installed
Select all Android software on version 22.*
Click on Uninstall
Work with: https://dl-ssl.google.com/android/eclipse/
Select Developer Tools and Next
Next, Accept the license agreement and Finish.
EDIT :
This trick is probably no more necessary!
Try to upgrade your SDK tools to 23.0.2+ and build&platform tools to rev 20 before.

The best solution to this is to download a new ADT from http://developer.android.com/sdk/index.html

Go to Help - About Eclipse and click Installation Details
On tab Installed Software, select all row that has version 22.6.3 then click Uninstall
Go to Help - Install new software, select work with ADT Plugin - http://dl-ssl.google.com/android/eclipse/
Check the Developer Tools and now install without conflict

AS you have done the upgrade to SDK 23.0 without upgrading the ADT it will show this kind error as you have mentioned in the screen shot.
Simply upgrading the SDK to 23.0 is of no use until and unless you also update the related development tool in ADT.
Follow the steps
First delete the SDK 23.0 and update the ADT to 23.0
For doing the update you need to click on Install new software from
help and choose the ADT/https://dl-ssl.google.com/android/eclipse/
under the link upon which you get the new Development tools to
update click all >next to continue .
Upon successful completion you can now update the SDK to 23.0.
Note:- Many of those who tried to update the SDK have face a problem Cannot complete the installation because of conflict dependancy
So its better to just stick to the 22.6v of the ADT.
The update to 23.0 is filled with bugs and it will take some time to fix the bugs

I also got the error of OP this morning. I clicked on "Check for Updates" but it was always saying "No updates available".
I found this thread and thought "Oh man, I'm gonna sit on this all day".
But lucky for me (and for you who will find this thread perhaps in a few weeks), the solution is getting easier. I just did this:
Help > Install New Software
choose the update site https://dl-ssl.google.com/android/eclipse/
it offered me the new ADT-Packages with version 23.0.3 and I chose all of them
it showed me the known conflicting-dependency-error BUT offered me directly a solution: It will deinstall the 22* ADT-packages for me. I just clicked "ok" and it automatically deinstalled the old packages and installed the new ones :)

no need to do any thing,
just download new eclipse, install ADT 23.0.0 from below link
https://dl-ssl.google.com/android/eclipse/
your problem solve...
its happened because you have SDK 23.0.1 and ADT 23.0.1 update not available....
yesterday i have same issue, i have solved that..

You are not alone.
This thing happened also to me. I tried many many solutions suggested on the internet but I had to use the "PLAN B"
I downloaded and installed new adt bundle and reimported all my projects and libraries. It takes some time but it is not that long :)
I hope that google will come up with fix, because the update to 23.0.0.2 also didnt work for me (same error).
So keep smiling and install new ADT :)

On Linux (Ubuntu), I managed to solve the problem in a bit of a 'hackish' way. It may be useful if you're reluctant to download stuff all over again (like me) :)
Warning: I suspect this won't work if the ADT and SDK versions are too far apart. (For me, it worked for ADT 22.6.2 and Android SDK update 24.)
Modify the file $SDK_HOME/tools/lib/plugin.prop ($SDK_HOME = base directory of your Android SDK installation), to contain the current ADT version, instead of the actual (updated) SDK version. In my case the original content of the file was
plugin.version=23.0.0
which I changed as
plugin.version=22.6.2
This suppresses the "Please update ADT..." issue, but ADT won't work properly as it won't be able to identify some of the components relocated by newer SDK updates.
Create shortcuts (symlinks) or copies of missing SDK components, at the locations where ADT expects to see them. You can find the expected locations using ADT's error consoles.
For example, in my case, the DDMS console showed an error
[2016-02-27 19:33:33 - DDMS] DDMS files not found: /usr/lib/sdk/tools/hprof-conv
as soon as I tried to switch to the DDMS perspective. So I just created a symlink $SDK_HOME/tools/hprof-conv pointing to $SDK_HOME/platform-tools/hprof-conv (which has been relocated):
me#computer:$SDK_HOME/tools$ ln -s ../platform-tools/hprof-conv hprof-conv
For me, after these 2 steps, ADT started working without any problems/errors.

#Kalpesh DON'T delete SDK 23.0 it will remove your "tools" folder and you won't be able to run SDK Manager after that. I know because I have just done that. Bad suggestion!
The solution from Kikiwa worked for me.

I have also come across this issue and figure out few steps that will help in a way or other.
One thing to note that the error "This Android SDK requires Android Developer Toolkit version 23.0.0 or above" will only come if you have updated your Android SDK Tool and Android SDK Platform Tool before updating your ADT.
Here are the steps that will help you to get rid of this: -
You can try the steps provided by Kikiwa but that might create some issues like removing your android SDK. So the solution is to re-configure your eclipse with re-installing the Android SDK.
Steps given by user285oo6 will also create some issues like when you delete the Updated SDK 23.0 then it will also remove the files from Platform-tools and tools folder from SDK directory. Now your eclipse wont start as it wont find the necessary files that are required to identify Android SDK or it may throw and error says "cannot find tools for the SDK" or "cannot find the version of ADT" or "emulator.exe not found".
In this case the solution is to restore your SDK Manager files along with Platform-tools and tools folder. Now the question arises how you will get it? Below are links for the same
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
This will download the SDK platform ZIP files and it contains the SDK manager along with tools folder. My Suggestion is to extract them and replace the
-tools folder
-SDK Manager.exe
-AVD Manager.exe
in your android SDK directory.
Now you have latest ADT installed (if you have follow the user285oo6 steps. If not then install it using your eclipse with URL https://dl-ssl.google.com/android/eclipse/) i.e. version 23.x.x and SDK on the older version.
Now you have to restart your eclipse and update the Android SDK tool and SDK Platform tool. This will work. I have done it for windows OS and was able to get it up and running
I know I am bit late but its always good to be late then never.
Please let me know if anyone has any question or confusion with the steps

Android ADT 23 Update - Cannot complete the install because of a conflicting dependency

This is what I got when trying to update:

How can I solve this?

I was facing the same issue and resolved it by uninstalling the previous version of ADT completely and then installing the new version.
Try it out.

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.

I downloaded Eclipse Luna without ADT. This is important.
Depending on where you saved your workspace and what version of eclipse you were using before a pop up might come up saying that it will migrate to Eclipse Luna etc2. I chose to migrate to Luna.
I then went to help -> install new software and added the ADT plugin via https://dl-ssl.google.com/android/eclipse.
I have run my app I was developing on ADT 22.xx and it runs fine on the emulator and my own nexus 5.
I hope this helps.....

I was using Eclipse Luna. I downloaded SDK 23. Then when I read ADT 23 released I was excited. I downloaded it too. But I relised it has many errors. I couldn't do anything with eclipse. I thought the other one, ADT 22 was good.
So I started to use Kepler again. I install SDK 22.6.2 and ADT 22.6.2 too. I am happy now. I have no errors anymore.
If it is running, do not touch it!

You have to Update your Google ADT to the Latest Version!
In Eclipse go to Help
Install New Software ---> Add
inside Add Repository write:
https://dl-ssl.google.com/android/eclipse/
Double click in the opening Box the 1 entry.
Follow the Eclipse instructions.
After loading some time you will get the newest Developer Tools and NDK Plugins
Repeat this for 2 times
