Eclipse ADT update does not work

I updated my android sdk to and I tried updating my adt via ecplise through
Help-> Check for updates
This action results in the dialog that says:
no updates found
But my SDK says:
This android is SDK requires Android Development Kit 21.1.0 or above
Current version is 21.1.0.v201212060256-543035
Please update ADT to the latest version.
Help me out and you have my enormous undying gratitude.

Edit. 26/03/2016
Please note that Google Announced: Support for the Android Developer Tools (ADT) in Eclipse has ended, so consider migration to Android Studio.
Solution:
The fastest installation way I found to solve that without deleting eclipse, or losing any data/settings:
Go here download latest version of ADT, current ADT-23.0.7.zip (*)
At Eclipse > Help > Install new software... > Uncheck Contact all update sites during install to find required software (bottom, last preference) in order to avoid any unwanted delays during install.
Same screen (top) Click Add > Archive > select downloaded ADT-X.X.X.zip > follow on screen installation steps
As a user mentioned in a comment if you still face problems on updating like that you may try removing the previous version of ADT before installation.
(*) Previous versions:
ADT-23.0.0.zip | ADT-23.0.2.zip | ADT-23.0.3.zip | ADT-23.0.4.zip | ADT-23.0.6.zip
ADT-22.6.0.zip | ADT-22.6.1.zip | ADT-22.6.2.zip | ADT-22.6.3.zip
ADT-22.3.0.zip
ADT-22.2.1.zip
ADT-22.0.0.zip | ADT-22.0.1.zip | ADT-22.0.5.zip
ADT-21.1.0.zip
Edit to fit the updates of ADT, this solution seems to work in any version :D

I had similar issue when upgrading to 22.6.1 and I got support from Android team. The solution was super simple.
You need to go Help - Install new software and choose there httpS:// (s is important) update site, and then execute installation.
Check out this solution on Android issue tracker.

I had another issue with ADT 23+.
My ADT plugin was out-of-date, but Eclipse was still saying that the latest version was already installed.
Installing manually the latest ADT version with the archive was not working either.
Eclipse was wrong so I made a clean install of ADT Plugins.
Uninstall ADT in Eclipse: Help > About Eclipse > Installation Details
Select the plugins then click on Uninstall...
Relaunch Eclipse
Install ADT again: Help > Install New Software...

I had the same problem. The command line update didn't work for me for some reason. It's some sort of bug that I haven't experienced in any update before this one. Here's what I did to fix it:
I deleted my eclipse installation
Downloaded a fresh copy of the sdk from the developer website
unzipped the sdk and copied only the eclipse folder
replaced my old eclipse folder with this one (deleted the rest of the download since I already had the sdk)
started up eclipse and pointed the workspace location to the old workspace I already had. All my projects were back as I had left them.
There might be other methods as well. This one seemed simplest to me. Others have suggested updating every eclipse component one by one and things like that but it seemed too tedious to me. If your eclipse installation is heavily customized and you have a lot of plugins installed then it might make sense to find an alternative. My install is always pretty minimalistic so I didn't mind throwing it away and starting from scratch.
Hope this helps!

And at the page Google for Android Development at link http://developer.android.com/sdk/installing/installing-adt.html#Troubleshooting
They say:
If Eclipse can not find the remote update site containing the ADT plugin, try changing the remote site URL to use http, rather than https. That is, set the Location for the remote site to:
http://dl-ssl.google.com/android/eclipse/
For me - it's help.

If the solution of madlymad is not working, you could also try this solution which has worked for me.
In short: completely uninstall adt and then use the archive to install it again (as suggested above).
Without the uninstall i ran into conflicting jars.

Download Updated bundles here:
win32: Here
Unfortunately, you will NOT be able to update an existing installation. Just use a new copy of Eclipse and install the plugins using the update site, or use the bundle.
OR
You can fix this issue by removing all old Android plugins. Once you have removed all of the old Android plugins you can then install the new ones.
Open Eclipse
Select Help
Select About Eclipse SDK
Select Installation details
High light all Android plugins
Select Uninstall
Restart Eclipse
Then install the plugins again as normal
Restart Eclipse
At this point everything should be working again.

You can always try to update the SDK Tools and Platform tools outside Eclipse.
in CMD or Terminale type:
$ android
and the SDK manager will start.

ADT plugin doesn't show up in Eclipse

I've followed the instruction here for installing ADT, but I don't see any sign of ADT in Eclipse, except that it's installed.
According to what it says here, I should have additional project templates, which are missing. See the screenshots:

Besides reinstalling eclipse and reloading the ADT I have found another solution :
Inside Eclipse ->Window ->Customize Perspective ->Command Groups Availability ->Check All Android groups -> OK
That should solve any issues. Currently there are four (4) android groups.
Good luck guys!

You Simply need to Download the ADT Plugin. Please look at step by step guide here.
Start Eclipse, then select Help > Install New Software....
Click Add, in the top-right corner.
In the Add Repository dialog that appears, enter "ADT Plugin" for the Name and the following URL for the Location:
https://dl-ssl.google.com/android/eclipse/
Click OK
Note: If you have trouble acquiring the plugin, try using "http" in the Location URL, instead of "https" (https is preferred for security reasons).
In the Available Software dialog, select the checkbox next to Developer Tools and click Next.
In the next window, you'll see a list of the tools to be downloaded. Click Next.
Read and accept the license agreements, then click Finish.
Note: If you get a security warning saying that the authenticity or validity of the software can't be established, click OK.
When the installation completes, restart Eclipse.

I'm on Ubuntu and had the same problem as the poster. Had to run Eclipse as sudo and do the ADT install (into the same workspace as my non-root user account).
Restarted Eclipse as a non-root user and everything works.

I think you have to update JDK.
Please check JDK version.
#java -version
I've meet same problem when I use JDK 1.5 on ubuntu.

The answer is here: Android ADT Plugin doesn't show up in Eclipse
Actually, running as administrator on Win7 worked for me after uninstalling ADT.
Another thing is to execute eclipse with the parameter -clean after uninstalling ADT.

When you load the Android ADT plugins, using Help -> Install New Software, you need to have started Eclipse with "run as administrator". If you installed the ADT plugins without having run Eclipse as administrator, it might not work when you go to Windows -> Preferences...., and Android doesn't appear in the left panel.

make sure you have the latest jdk installed. that was the issue in my case

Somehow, your installation didn't register properly. Try removing ADT and reinstalling it.
To uninstall, go to Window > Preferences > Install/Upload, then click on the "Uninstall or update" link. Find ADT (and related software), remove, then try to reinstall.

I had to reinstall Eclipse and that solved the problem.

ADT Plugin Won't Install

I am using Eclipse Indigo on Windows 7 and have repeatedly tried to install the ADT Plugin for android but to no avail. I have tried: using Eclipse 3.6, downloading the .ZIP file, checking for updates and trying again, using the "http" protocol instead of the "https" in the repository. None of them worked.
However, whenever I try to install it, it either freezes at "calculating dependencies and requirements" or says
"Cannot complete the install because one or more required items could not be found.
Software being installed: Android Development Tools 16.0.1.v201112150204-238534 (com.android.ide.eclipse.adt.feature.group 16.0.1.v201112150204-238534)"
Someone please help, I desperately need android for my projects.

Run Eclipse as Administrator, if you're not already.

What package of Eclipse did you download? Perhaps the package you have doesn't include some pre-requisite that ADT needs.See if my answer to this question help solve your problem.
Also, it would help to see more of the failure reason. We know you're trying to install ADT, what's important is what comes after that, the part that tells which requires items can't be found.

It seems this issue is due to proxy. Please try to download plugin locally, by link:
dl.google.com/android/ADT-16.0.1.zip
extract zip file.
In Eclipse go to help-> install new software-> Select add
Select to local, and browse to your downloaded package. If problem still persists, try without proxy.

Eclipse Indigo Android ADT - install OK, no "Android" option in Preferences and New Project

I have Eclipse (Indigo Service Release 1, Build id: 20110916-0149) running on Win XP.
I've added
https://dl-ssl.google.com/android/eclipse/
and installed 4 plugins, including ADT, and restarted Eclipse.
Installed software list shows Android plugins are installed.
But nothing appears in Preferences, and there are no Android-type project in New Projects.
Later I check Eclipse's directories and there were four *.jar archives with these Android plugins, and they weren't unzipped to corresponding directories (like other plugins). I unpacked them so directories same as *.jar names, and started Eclipse again, but nothing happens.
How can I work with ADT plugin in Eclipse?

I just had the same problem on windows 7 running Indigo. I eventually discovered that I had accidentally not run Eclipse as an administrator when I installed the ADT plugin. I solved the issue by uninstalling the ADT plugin, and then re-installing the ADT plugin when running Eclipse as an administrator. Once I did that Eclipse restarted and immediately prompted me for the location of my android SDK.
As far as steps go:
Run Eclipse as Administrator
Go to Help > About Eclipse SDK > Installation Details
Select Android DDMS, Android Development Tools, Android Hierarchy Viewer, and Android Traceview
Click Uninstall and click through the dialogs
Restart Eclipse at the prompt
Close Eclipse and re-run it as an administrator (not sure if this was necessary but I wanted be sure Eclipse had full permissions when I reinstalled the ADT Plugin)
Re-install the ADT plugin the way you did before.
Restart Eclipse at the prompt.

Q: Did you install the Android SDK?
You need to do this in addition to installing a) Java, b) Eclipse and c) the Android plugins for Eclipse
Here's one (of many!) "Quick Start Guides" for setting up Android on your development PC:
http://www.talkandroid.com/guides/developer/android-sdk-install-guide/
PS:
Please don't "unpack" anything, except unzipping Eclipse itself.
You might actually wish to delete your install and re-install from scratch (just to make sure there isn't anything "weird" in your environment).

Well i had this issue as well, but what i see its one componment that isnt on the google servers (at least for indigo) com.android.ide.eclipse.adt_20.0.0.v201206242043-391819.jar
you need download the ADT from google server ADT 20.00 and the install new software in help menu as always
In the Add Site dialog, click Archive.
Browse and select the downloaded zip file.
Enter a name for the local update site (e.g., "ADT-20.0.0.zip") in the "Name" field.
Click OK.
and done choose the ADT developer that i bet you dont have installed that should fix the problem ;)

I tried everything and nothing worked until I made my JAVA_HOME and PATH point to my JDK 6, they were pointing to the 5, then before installing the ADT plugin, make sure Eclipse is using the JDK 6 in Preferences/Java/Installed JREs. Of course make sure you are running/installing everything as an administrator.

You should install start SDK package (download), after that install android packages by windows/SDK manager. After that you§ll see everything you've mentioned

I encountered the same problem today, and a simple removal of the installed plugin is not helpful. My final solution is:
Remove the Android DDMS, Android Development Tools, Android Hierarchy Viewer, Android TraceView and Tracer for OpenGL ES first.
Remove the com.android.ide.eclipse.adt.package_version_info and other adt related jar directory under eclipse_home/plugins/. It is very easy to recognize based on its version_info on its name.
Modify the artifact.xml under eclipse_home, remove all artifact tag related with 'adt'.
Reinstall Android ADT again with Admin Privilege.

If you are going to reinstall as administrator make sure to remove the ADT Plugin from the Windows > Preferences > Install/Update > Available Software Sites.
Also something that may help is when installing the ADT Plugin you get the option for Developer Tools which the http://developer.android.com/sdk/installing/installing-adt.html guide tells you to select, but make sure to also select NDK Plugins.
And as usual do this while running as administrator. It probably doesn't make a difference but instead of clicking restart I closed Eclipse and reopened as administrator each time it was necessary.
As far as I can tell the NDK Plugin was the only thing I did differently when I finally got it to work.

I have Ubuntu , to make story short, I tried every advice here, nothing helped (reinstall, ADT removal- adding, run as sudo, deleting .eclipse folder etc).
The cause of problem was running eclipse updates.
So, I downloaded ADT bundle as zip - adt-bundle-linux-x86_64-20130729
unpacked it, run eclipse inside it, used existing workplace, and it worked, 'android' option appeared in Preferences.
However, there is no longer 'eclipse' splash logo at start-up, it's now called Android Developer Tools
Build: v22.0.5-757759

The real solution to this issue is that you MUST run Eclipse as an Administrator before you install. There are a number of plugins that have this same issue.

Problem while installing ADT on eclipse galileo (ubuntu)

I have eclipse Galileo installed my ubuntu machine. It was working fine with Android 2.2 ADT.
But in between something happened and I was not able to run any program. So I uninstalled Eclipse and reinstalled. Now When I try to installed ADT, it is giving errors.

Please help me to install ADT on eclipse.

Try it and if it works:
http://android-er.blogspot.com/2009/11/cannot-complete-install-because-one-or.html

Go to **window>>Preferences>>android and proper sdk location is given or not.. and then click apply..

Start Eclipse, then select Help > Install New Software....
Click Add, in the top-right corner.
In the Add Site dialog, click Archive.
Browse and select the downloaded zip file.
Enter a name for the local update site (e.g., "Android Plugin") in the "Name" field.
Click OK.
If it will not work then give ADT plugin location directly from internet.
